This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
DESCRIPTION
The Texas Instruments MSP430™ family of ultra-low-power microcontrollers consist of several devices featuring
different sets of peripherals targeted for various applications. The architecture, combined with five low-power
modes is optimized to achieve extended battery life in portable measurement applications. The device features a
powerful 16-bit RISC CPU, 16-bit registers, and constant generators that contribute to maximum code efficiency.
The digitally controlled oscillator (DCO) allows wake-up from low-power modes to active mode in less than 1 µs.
The MSP430F22x4/MSP430F22x2 series is an ultra-low-power mixed signal microcontroller with two built-in
16-bit timers, a universal serial communication interface, 10-bit A/D converter with integrated reference and data
transfer controller (DTC), two general-purpose operational amplifiers in the MSP430F22x4 devices, and 32 I/O
pins.
Typical applications include sensor systems that capture analog signals, convert them to digital values, and then
process the data for display or for transmission to a host system. Stand-alone radio-frequency (RF) sensor front
ends are another area of application.

Interrupt Vector Addresses
The interrupt vectors and the power-up starting address are located in the address range of 0FFFFh to 0FFC0h.
The vector contains the 16-bit address of the appropriate interrupt handler instruction sequence.
If the reset vector (located at address 0FFFEh) contains 0FFFFh (for example, if flash is not programmed), the
CPU goes into LPM4 immediately after power up.

Bootstrap Loader (BSL)
The MSP430 bootstrap loader (BSL) enables users to program the flash memory or RAM using a UART serial
interface. Access to the MSP430 memory via the BSL is protected by user-defined password. For complete
description of the features of the BSL and its implementation, see the MSP430 Programming Via the Bootstrap
Loader User’s Guide (SLAU319).

Flash Memory
The flash memory can be programmed via the JTAG port, the bootstrap loader, or in-system by the CPU. The
CPU can perform single-byte and single-word writes to the flash memory. Features of the flash memory include:
•
Flash memory has n segments of main memory and four segments of information memory (A to D) of
64 bytes each. Each segment in main memory is 512 bytes in size.
•
•
Segments 0 to n may be erased in one step, or each segment may be individually erased.
Segments A to D can be erased individually, or as a group with segments 0 to n.
Segments A to D are also called information memory.
•
Segment A contains calibration data. After reset, segment A is protected against programming and erasing. It
can be unlocked, but care should be taken not to erase this segment if the device-specific calibration data is
required.

Peripherals are connected to the CPU through data, address, and control buses and can be handled using all
instructions. For complete module descriptions, see the MSP430x2xx Family User's Guide (SLAU144).
Oscillator and System Clock
The clock system is supported by the basic clock module that includes support for a 32768-Hz watch crystal
oscillator, an internal very-low-power low-frequency oscillator, an internal digitally-controlled oscillator (DCO), and
a high-frequency crystal oscillator. The basic clock module is designed to meet the requirements of both low
system cost and low power consumption. The internal DCO provides a fast turn-on clock source and stabilizes in
less than 1 µs. The basic clock module provides the following clock signals:
•
Auxiliary clock (ACLK), sourced from a 32768-Hz watch crystal, a high-frequency crystal, or the internal
very-low-power LF oscillator.
•
•
Main clock (MCLK), the system clock used by the CPU.
Sub-Main clock (SMCLK), the sub-system clock used by the peripheral modules.

Brownout
The brownout circuit is implemented to provide the proper internal reset signal to the device during power on and
power off.
Digital I/O
There are four 8-bit I/O ports implemented—ports P1, P2, P3, and P4:
•
•
•
•
•
All individual I/O bits are independently programmable.
Any combination of input, output, and interrupt condition is possible.
Edge-selectable interrupt input capability for all eight bits of port P1 and P2.
Read/write access to port-control registers is supported by all instructions.
Each I/O has an individually programmable pullup/pulldown resistor.
Because there are only three I/O pins implemented from port P2, bits [5:1] of all port P2 registers read as 0, and
write data is ignored.
Watchdog Timer (WDT+)
The primary function of the WDT+ module is to perform a controlled system restart after a software problem
occurs. If the selected time interval expires, a system reset is generated. If the watchdog function is not needed
in an application, the module can be disabled or configured as an interval timer and can generate interrupts at
selected time intervals.

Universal Serial Communications Interface (USCI)
The USCI module is used for serial data communication. The USCI module supports synchronous
communication protocols like SPI (3 or 4 pin), I2C and asynchronous communication protocols such as UART,
enhanced UART with automatic baudrate detection (LIN), and IrDA.
USCI_A0 provides support for SPI (3 or 4 pin), UART, enhanced UART, and IrDA.
USCI_B0 provides support for SPI (3 or 4 pin) and I2C.
ADC10
The ADC10 module supports fast, 10-bit analog-to-digital conversions. The module implements a 10-bit SAR
core, sample select control, reference generator and data transfer controller, or DTC, for automatic conversion
result handling allowing ADC samples to be converted and stored without any CPU intervention.

Vhys(B_IT-) is ≤ 1.8 V.
(2) During power up, the CPU begins code execution following a period of td(BOR) after VCC = V(B_IT-) + Vhys(B_IT-) . The default DCO settings
must not be changed until VCC ≥ VCC(min), where VCC(min) is the minimum supply voltage for the desired operating frequency.

All ranges selected by RSELx overlap with RSELx + 1: RSELx = 0 overlaps RSELx = 1, ... RSELx = 14
overlaps RSELx = 15.
•
•
DCO control bits DCOx have a step size as defined by parameter SDCO .
Modulation control bits MODx select how often fDCO(RSEL,DCO+1) is used within the period of 32 DCOCLK
cycles. The frequency fDCO(RSEL,DCO) is used for the remaining cycles. The frequency is an average equal to:

(1) To improve EMI on the XT1 oscillator, the following guidelines should be observed.
(a) Keep the trace between the device and the crystal as short as possible.
(b) Design a good ground plane around the oscillator pins.
(c) Prevent crosstalk from other clock or data lines into oscillator pins XIN and XOUT.
(d) Avoid running PCB traces underneath or adjacent to the XIN and XOUT pins.
(e) Use assembly materials and praxis to avoid any parasitic load on the oscillator XIN and XOUT pins.
(f) If conformal coating is used, ensure that it does not induce capacitive/resistive leakage between the oscillator pins.
(g) Do not route the XOUT line to the JTAG header to support the serial programming adapter as shown in other documentation. This
signal is no longer required for the serial programming adapter.
(2) Includes parasitic bond and package capacitance (approximately 2 pF per pin).
Because the PCB adds additional capacitance, it is recommended to verify the correct load by measuring the ACLK frequency. For a
correct setup, the effective load capacitance should always match the specification of the crystal that is used.
(3) Frequencies below the MIN specification set the fault flag. Frequencies above the MAX specification do not set the fault flag.
Frequencies in between might set the flag.
(4) Measured with logic-level input frequency but also applies to operation with crystals.

(1) The leakage current is defined in the leakage current table with Px.x/Ax parameter.
(2) The analog input voltage range must be within the selected reference voltage range VR+ to VR- for valid conversion results.
(3) The internal reference supply current is not included in current consumption parameter IADC10
.
(4) The internal reference current is supplied via terminal VCC. Consumption is independent of the ADC10ON control bit, unless a
conversion is active. The REFON bit enables the built-in reference to settle before starting an A/D conversion.

(1) The external reference is used during conversion to charge and discharge the capacitance array. The input capacitance, CI, is also the
dynamic load for an external reference during conversion. The dynamic impedance of the reference supply should follow the
recommendations on analog-source impedance to allow the charge to settle for 10-bit accuracy.
(2) The accuracy limits the minimum positive external reference voltage. Lower reference voltage levels may be applied with reduced
accuracy requirements.
(3) Under this condition, the external reference is internally buffered. The reference buffer is active and requires the reference buffer supply
current IREFB. The current consumption can be limited to the sample and conversion period with REBURST = 1.
(4) The accuracy limits the maximum negative external reference voltage. Higher reference voltage levels may be applied with reduced
accuracy requirements.
(5) The accuracy limits the minimum external differential reference voltage. Lower differential reference voltage levels may be applied with
reduced accuracy requirements.

(1) The sensor current ISENSOR is consumed if (ADC10ON = 1 and REFON = 1), or (ADC10ON = 1 and INCH = 0Ah and sample signal is
high).When REFON = 1, ISENSOR is included in IREF+.When REFON = 0, ISENSOR applies during conversion of the temperature sensor
input (INCH = 0Ah).
(2) The following formula can be used to calculate the temperature sensor output voltage:
VSensor,typ = TCSensor ( 273 + T [°C] ) + VOffset,sensor [mV] or
VSensor,typ = TCSensor T [°C] + VSensor(TA = 0°C) [mV]
(3) Results based on characterization and/or production test, not TCSensor or VOffset,sensor

(4) No additional current is needed. The VMID is used during sampling.
(5) The on time, tVMID(on), is included in the sampling time, tVMID(sample); no additional on time is needed.

JTAG Fuse Check Mode
MSP430 devices that have the fuse on the TEST terminal have a fuse check mode that tests the continuity of the
fuse the first time the JTAG port is accessed after a power-on reset (POR). When activated, a fuse check
current, ITF , of 1 mA at 3 V, 2.5 mA at 5 V can flow from the TEST pin to ground if the fuse is not burned. Care
must be taken to avoid accidentally activating the fuse check mode and increasing overall system power
consumption.
When the TEST pin is again taken low after a test or programming session, the fuse check mode and sense
currents are terminated.
Activation of the fuse check mode occurs with the first negative edge on the TMS pin after power up or if TMS is
being held low during power up. The second positive edge on the TMS pin deactivates the fuse check mode.
After deactivation, the fuse check mode remains inactive until another POR occurs. After each POR the fuse
check mode has the potential to be activated.
The fuse check current flows only when the fuse check mode is active and the TMS pin is in a low state (see
Figure 28). Therefore, the additional current flow can be prevented by holding the TMS pin high (default
condition).

NOTE
The CODE and RAM data protection is ensured if the JTAG fuse is blown and the 256-bit
bootloader access key is used. Also, see the Bootstrap Loader section for more
information.
