Overview

®

ARM core with embedded Flash & RAM

The STR710 series is a family of ARM-powered 32-bit Microcontrollers with embedded

Flash and RAM. It combines the high performance ARM7TDMI CPU with an extensive

range of peripheral functions and enhanced I/O capabilities. STR71xF devices have on-chip

high-speed single voltage FLASH memory and high-speed RAM. STR710R devices have

high-speed RAM but no internal Flash. The STR710 family has an embedded ARM core

and is therefore compatible with all ARM tools and software.

Extensive tools support

STMicroelectronics’ 32-bit, ARM core-based microcontrollers are supported by a complete

range of high-end and low-cost development tools to meet the needs of application

developers. This extensive line of hardware/software tools includes starter kits and complete

development packages all tailored for ST’s ARM core-based MCUs. The range of

development packages includes third-party solutions that come complete with a graphical

development environment and an in-circuit emulator/programmer featuring a JTAG

application interface. These support a range of embedded operating systems (OS), while

several royalty-free OSs are also available.

For more information, please refer to ST MCU site http://www.st.com/mcu

Package Choice: Low Pin-Count 64-pin or Feature-Rich 144-pin LQFP or BGA

The STR710 family is available in 5 main versions.

The 144-pin versions have the full set of all features including CAN, USB and External

Memory Interface (EMI).

●

STR710F: 144-pin BGA or LQFP with CAN, USB and EMI

●

STR710R: Flashless 144-pin BGA or LQFP with CAN, USB and EMI (no internal Flash

memory)

4/74

STR71xF

Introduction

The three 64-pin versions (BGA or LQFP) do not include External Memory Interface.

●

STR715F: 64-pin BGA or LQFP without CAN or USB

STR711F: 64-pin BGA or LQFP with USB

STR712F: 64-pin BGA or LQFP with CAN

High Speed Flash Memory (STR71xF)

The Flash program memory is organized in two banks of 32-bit wide Burst Flash memories

enabling true read-while-write (RWW) operation. Device Bank 0 is up to 256 Kbytes in size,

typically for the application program code. Bank 1 is 16K bytes, typically used for storing

data constants. Both banks are accessed by the CPU with zero wait states @ 33 MHz

Bank 0 memory endurance is 10K write/erase cycles and Bank 1 endurance is 100K

write/erase cycles. Data retention is 20 years on both banks. The two banks can be

accessed independently in read or write. Flash memory can be accessed in two modes:

●

Burst mode: 64-bit wide memory access at up to 50 MHz.

●

Direct 32-bit wide memory access for deterministic operation at up to 33 MHz.

The STR7 embedded Flash memory can be programmed using In-Circuit Programming or

In-Application programming.

IAP (In-Application Programming): The IAP is the ability to re-program the Flash memory

of a microcontroller while the user program is running.

ICP (In-Circuit Programming): The ICP is the ability to program the Flash memory of a

microcontroller using JTAG protocol while the device is mounted on the user application

board.

The Flash memory can be protected against different types of unwanted access

(read/write/erase). There are two types of protection:

●

Sector Write Protection

●

Flash Debug Protection (locks JTAG access)

Refer to the STR7 Flash Programming Reference manual for details.

Optional External Memory (STR710)

The non-multiplexed 16-bit data/24-bit address bus available on the STR710 (144-pin)

supports four 16-Mbyte banks of external memory. Wait states are programmable

individually for each bank allowing different memory types (Flash, EPROM, ROM, SRAM

etc.) to be used to store programs or data.

Figure 1 shows the general block diagram of the device family.

Flexible Power Management

To minimize power consumption, you can program the STR710 to switch to SLOW, WAIT,

LPWAIT (low power wait), STOP or STANDBY mode depending on the current system

activity in the application.

Flexible Clock Control

Two external clock sources can be used, a main clock and a 32 kHz backup clock. The

embedded PLL allows the internal system clock (up to 66 MHz) to be generated from a main

clock frequency of 16 MHz or less. The PLL output frequency can be programmed using a

wide selection of multipliers and dividers. The microcontroller core, APB1 and APB2

peripherals are in separate clock domains and can be programmed to run at different

frequencies during application runtime. The clock to each peripheral is gated with an

5/74

Introduction

STR71xF

individual control bit to optimize power usage by turning off peripherals any time they are not

required.

Voltage Regulators

The STR710 requires an external 3.0-3.6V power supply. There are two internal Voltage

Regulators for generating the 1.8V power supply for the core and peripherals. The main VR

is switched off during low power operation.

Low Voltage Detectors

Each voltage regulator has an embedded LVD that monitors the internal 1.8V supply. If the

regulated voltage drops below a certain threshold, the LVD will reset the STR710. This

enhances the security of the system by preventing the MCU from going into an

unpredictable state.

An external reset circuit must be used to provide the RESET at V power-up. It is not

33

sufficient to rely on the RESET generated by the LVD in this case. This is because LVD

operation is guaranteed only when V is within the specification.

1.2

On-Chip Peripherals

CAN Interface (STR710 and STR712)

The CAN module is compliant with the CAN specification V2.0 part B (active). The bit rate

can be programmed up to 1 MBaud.

USB Interface (STR710 and STR711)

The full-speed USB interface is USB V2.0 compliant and provides up to 16 bidirectional/32

unidirectional endpoints, up to 12 Mb/s (full-speed), support for bulk transfer, isochronous

transfers and USB Suspend/Resume functions.

Standard Timers

Each of the four timers have a 16-bit free-running counter with 7-bit prescaler

Three timers each provide up to two input capture/output compare functions, a pulse

counter function, and a PWM channel with selectable frequency.

The fourth timer is not connected to the I/O ports. It can be used by the application software

for general timing functions.

Realtime Clock (RTC)

The RTC provides a set of continuously running counters driven by the 32 kHz external

crystal. The RTC can be used as a general timebase or clock/calendar/alarm function.

When the STR710 is in Standby mode the RTC can be kept running, powered by the low

power voltage regulator and driven by the 32 kHz external crystal.

UARTs

The 4 UARTs allow full duplex, asynchronous, communications with external devices with

independently programmable TX and RX baud rates up to 1.25 Mb/s.

Smart Card Interface

UART1 is configurable to function either as a general purpose UART or as an asynchronous

Smart Card interface as defined by ISO 7816-3. It includes Smart Card clock generation and

provides support features for synchronous cards.

6/74

STR71xF

Introduction

Buffered Serial Peripheral Interfaces (BSPI)

Each of the two SPIs allow full duplex, synchronous communications with external devices,

master or slave communication at up to 5.5Mb/s in Master mode and 4 Mb/s in Slave mode.

2

I C Interfaces

2

The two I C Interfaces provide multi-master and slave functions, support normal and fast

2

I C mode (400 kHz) and 7 or 10-bit addressing modes.

2

One I C Interface is multiplexed with one SPI, so either 2xSPI+1x I C or 1xSPI+2x I C may

be used at a time.

HDLC interface

The High Level Data Link Controller (HDLC) unit supports full duplex operation and NRZ,

NRZI, FM0 or MANCHESTER protocols. It has an internal 8-bit baud rate generator.

A/D Converter

The Analog to Digital Converter, converts in single channel or up to 4 channels in single-

shot or round robin mode. Resolution is 12-bit with a sampling frequency of up to 1 kHz. The

input voltage range is 0-2.5V.

Watchdog

The 16-bit Watchdog Timer protects the application against hardware or software failures

and ensures recovery by generating a reset.

I/O Ports

The 48 I/O ports are programmable as Inputs or Outputs.

External Interrupts

Up to 14 external interrupts are available for application use or to wake-up the application

from STOP mode.

1. The Reset configuration of the I/O Ports is IPUPD (input pull-up/pull down). Refer to Table 7 on page 28.

The Port bit configuration at reset is PC0=1, PC1=1, PC2=0. The port data register bit (PD) value depends

on the pu/pd column which specifies whether the pull-up or pull-down is enabled at reset

2. In reset state, these pins configured as Input PU/PD with weak pull-up enabled. They must be configured

by software as Alternate Function (see Table 7: Port Bit Configuration Table on page 28) to be used by the

External Memory Interface.

3. In reset state, these pins configured as Input PU/PD with weak pull-down enabled to output Address

0x0000 0000 using the External Memory Interface. To access memory banks greater than 1Mbyte, they

need to be configured by software as Alternate Function (see Table 7: Port Bit Configuration Table on

page 28).

4. V_33IO-PLLand V₃₃are internally connected. V_SSIO-PLLand V_SSare internally connected.

5. During the reset phase, these pins are in input pull-up state. When reset is released, they are configured as

Output Push-Pull.

6. During the reset phase, these pins are in input pull-up state. When reset is released, they are configured as

Hi-Z.

7. During the reset phase, these pins are in input pull-down state. When reset is released, they are configured

as Output Push-Pull.

8. During the reset phase, and after reset is released, this pin is in Output Push-Pull state.

The Port bit configuration at reset is PC0=1, PC1=1, PC2=0. The port data register bit (PD) value depends

on the pu/pd column which specifies whether the pull-up or pull-down is enabled at reset

2. V_33IO-PLLand V₃₃are internally connected. V_SSIO-PLLand V_SSare internally connected.

Parameter conditions

Unless otherwise specified, all voltages are referred to V

.

2.1.1

Minimum and maximum values

Unless otherwise specified the minimum and maximum values are guaranteed in the worst

conditions of ambient temperature, supply voltage and frequencies by tests in production on

100% of the devices with an ambient temperature at T =25°C and T =T max (given by the

A

selected temperature range).

Data based on characterization results, design simulation and/or technology characteristics

are indicated in the table footnotes and are not tested in production. Based on

characterization, the minimum and maximum values refer to sample tests and represent the

mean value plus or minus three times the standard deviation (mean 3Σ).

2.1.2

2.1.3

Typical values

Unless otherwise specified, typical data are based on T =25°C, V =3.3V (for the

A

33

3.0V≤V ≤3.6V voltage range) and V =1.8V. They are given only as design guidelines and

33

18

are not tested.

Typical ADC accuracy values are determined by characterization of a batch of samples from

a standard diffusion lot over the full temperature range, where 95% of the devices have an

error less than or equal to the value indicated (mean 2Σ).

Typical curves

Unless otherwise specified, all typical curves are given only as design guidelines and are

not tested.

Notes:

1. I_INJ(PIN)must never be exceeded. This is implicitly insured if V_INmaximum is respected. If V_INmaximum

cannot be respected, the injection current must be limited externally to the I_INJ(PIN)value. A positive

injection is induced by V_IN>V₃₃while a negative injection is induced by V_IN<V_SS. For true open-drain pads,

there is no positive injection current, and the corresponding V_INmaximum must always be respected

2. All 3.3V power (V₃₃, AV_DD, V_33IO-PLL) and ground (V_SS, AV_SS, V_SSIO-PLL) pins must always be connected

to the external 3.3V supply.

3. Negative injection disturbs the analog performance of the device. See note in Section 2.3.9: ADC

characteristics on page 62.

4. When several inputs are submitted to a current injection, the maximum ΣI_INJ(PIN)is the absolute sum of the

positive and negative injected currents (instantaneous values). These results are based on

characterization with ΣI_INJ(PIN)maximum current injection on four I/O port pins of the device.

5. Only when using external 1.8V power supply. All the power (V₁₈, V_18BKP) and ground (V_SS18, V_SSBKP) pins

must always be connected to the external 1.8V supply.

OSC32K Crystal / Ceramic Resonator Oscillator

The STR7 RTC clock can be supplied with a 32kHz Crystal/Ceramic resonator oscillators.

All the information given in this paragraph are based on characterization results with

specified typical external components. In the application, the resonator and the load

capacitors have to be placed as close as possible to the oscillator pins in order to minimize

output distortion and start-up stabilization time. Refer to the crystal resonator manufacturer

for more details (frequency, package, accuracy...).

EMC characteristics

Susceptibility tests are performed on a sample basis during product characterization.

45/74

Electrical parameters

STR71xF

Functional EMS (Electro Magnetic Susceptibility)

Based on a simple running application on the product (toggling 2 LEDs through I/O ports),

the product is stressed by two electro magnetic events until a failure occurs (indicated by the

LEDs).

●

ESD: Electro-Static Discharge (positive and negative) is applied on all pins of the

device until a functional disturbance occurs. This test conforms with the IEC 1000-4-2

standard.

●

FTB: A Burst of Fast Transient voltage (positive and negative) is applied to V and

DD

V

through a 100pF capacitor, until a functional disturbance occurs. This test

SS

conforms with the IEC 1000-4-4 standard.

A device reset allows normal operations to be resumed. The test results are given in the

table below based on the EMS levels and classes defined in application note AN1709.

Designing hardened software to avoid noise problems

EMC characterization and optimization are performed at component level with a typical

application environment and simplified MCU software. It should be noted that good EMC

performance is highly dependent on the user application and the software in particular.

Therefore it is recommended that the user applies EMC software optimization and

prequalification tests in relation with the EMC level requested for his application.

Software recommendations:

The software flowchart must include the management of runaway conditions such as:

●

Corrupted program counter

Unexpected reset

Critical Data corruption (control registers...)

Prequalification trials:

Most of the common failures (unexpected reset and program counter corruption) can be

reproduced by manually forcing a low state on the RESET pin or the Oscillator pins for 1

second.

To complete these trials, ESD stress can be applied directly on the device, over the range of

specification values. When unexpected behavior is detected, the software can be hardened

to prevent unrecoverable errors occurring (see application note AN1015).

In the case of an ARM7 CPU, in order to write robust code that can withstand all kinds of

stress, such as very strong electromagnetic disturbance, it is mandatory that the Data Abort,

Prefetch Abort and Undefined Instruction exceptions are managed by the application

software. This will prevent the code going into an undefined state or performing any

unexpected operation.

Absolute Maximum Ratings (Electrical Sensitivity)

Based on three different tests (ESD, LU and DLU) using specific measurement methods, the

product is stressed in order to determine its performance in terms of electrical sensitivity.

For more details, refer to the application note AN1181.

Electro-Static Discharge (ESD)

Electro-Static Discharges (a positive then a negative pulse separated by 1 second) are

applied to the pins of each sample according to each pin combination. The sample size

depends on the number of supply pins in the device (3 parts*(n+1) supply pin). Two models

can be simulated: Human Body Model and Machine Model. This test conforms to the

JESD22-A114A/A115A standard.

Static and Dynamic Latch-Up

●

LU: 3 complementary static tests are required on 10 parts to assess the latch-up

performance. A supply overvoltage (applied to each power supply pin) and a current

injection (applied to each input, output and configurable I/O pin) are performed on each

sample. This test conforms to the EIA/JESD 78 IC latch-up standard. For more details,

refer to the application note AN1181.

●

DLU: Electro-Static Discharges (one positive then one negative test) are applied to

each pin of 3 samples when the micro is running to assess the latch-up performance in

dynamic mode. Power supplies are set to the typical values, the oscillator is connected

as near as possible to the pins of the micro and the component is put in reset mode.

This test conforms to the IEC1000-4-2 and SAEJ1752/3 standards. For more details,

refer to the application note AN1181.

Consequently, when using this I C in a multi-master network, it is not possible to power off

the STR7X while some another I C master node remains powered on: otherwise, the

ADC Accuracy vs. Negative Injection Current: Injecting negative current on any of the standard (non-

robust) analog input pins should be avoided as this significantly reduces the accuracy of the conversion

being performed on another analog input. It is recommended to add a Schottky diode (pin to ground) to

standard analog pins which may potentially inject negative current. The effect of negative injection current

on robust pins is specified in Section 2.3.5.

Any positive injection current within the limits specified for I_INJ(PIN)and ΣI_INJ(PIN)in Section 2.3.5 does not

affect the ADC accuracy.

Analog Power Supply and Reference Pins

The AV and AV pins are the analog power supply of the A/D converter cell. They act as

DD

SS

the high and low reference voltages for the conversion.

Separation of the digital and analog power pins allow board designers to improve A/D

performance. Conversion accuracy can be impacted by voltage drops and noise in the event

of heavily loaded or badly decoupled power supply lines (see: General PCB Design

Guidelines).

General PCB Design Guidelines

To obtain best results, some general design and layout rules should be followed when

designing the application PCB to shield the noise-sensitive, analog physical interface from

noise-generating CMOS logic signals.

●

Use separate digital and analog planes. The analog ground plane should be connected

to the digital ground plane via a single point on the PCB.

●

Filter power to the analog power planes. It is recommended to connect capacitors, with

good high frequency characteristics, between the power and ground lines, placing

power supply pins and a 1 to 10µF capacitor close to the power source (see Figure 35).

●

The analog and digital power supplies should be connected in a star network. Do not

use a resistor, as AV is used as a reference voltage by the A/D converter and any

DD

resistance would cause a voltage drop and a loss of accuracy.

Properly place components and route the signal traces on the PCB to shield the analog

inputs. Analog signals paths should run over the analog ground plane and be as short

as possible. Isolate analog signals from digital signals that may switch while the analog

inputs are being sampled by the A/D converter. Do not toggle digital outputs near the

A/D input being converted.

Software Filtering of Spurious Conversion Results

For EMC performance reasons, it is recommended to filter A/D conversion outliers using

software filtering techniques.
