i.MX 7ULP Applications

Processor—Industrial

MCIMX7U5CVP06SD

MCIMX7U3CVP06SD

The i.MX 7ULP product family members are optimized for power-

sensitive applications benefiting from NXP's Heterogeneous

Multicore Processing (HMP) architecture. Achieving an efficient

balance between processing power and deterministic processing

needs, the i.MX 7ULP is an asymmetric processor consisting of

two separate processing domains: an application domain and a

real-time domain. The application domain is built around an

ARM® Cortex®-A7 processor with an ARM NEON™ SIMD

engine and floating point unit (FPU) and is optimized for rich OS

based applications. The real-time domain is built around an ARM

Cortex-M4 processor (with FPU) optimized for lowest possible

leakage. Both domains are completely independent, with

separate power, clocking, and peripheral domains, but the bus

Plastic package: BGA 14x14mm, 0.5mm pitch

fabric of each domain is tightly integrated for efficient communication. The part is streamlined to minimize pin

count, enabling small packages and simple system integration.

Clocking

2.1 Introduction

This section details the clock sources, distribution and management within the i.MX

7ULP. These functions are under joint control of the System Clock Generation (SCG)

modules, Peripheral Clock Control (PCC) modules, and Core Mode Controller (CMC)

blocks.

NOTE

References in this chapter to “Core 0” or “Processor A”

correspond to the Cortex M4 core. References in this chapter

to “Core 1” or “Processor B” correspond to the Cortex A7

core.

The clocking scheme provides clear separation between M4 domain and A7 domain.

Except for a few clock sources shared between two domains, such as the System

Oscillator clock, the Slow IRC (SIRC), and the Fast IRC clock (FIRC), clock sources

and clock management are separated and contained within each domain.

M4 clock management consists of SCG0, PCC0, PCC1, and CMC0 modules.

A7 clock management consists of SCG1, PCC2, PCC3, and CMC1 modules.

2.2 Clock distribution

The SCG modules generate and distribute clocks on the device. SCG functions include:

• clock reference selection

• generation of clock used to derive processor, system, peripheral bus and external

memory interface clocks

• source selection for peripheral clocks

• control of power-saving clock-gating mode

PCC modules control clock selection, optional division and clock gating mode for

peripherals.

NOTE

• To bypass system oscillator and directly apply clock from

pin, SCG_SOSCCFG[EREFS] should be set to 0. The

direct clock should be applied on the EXTAL pin.

• For using oscillator reference,

SCG_SOSCCSR[SOSCEN] and

SCG_SOSCCFG[EREFS] should both be set to 1.

Clocking

2.3 External clock sources

In normal functional mode, this device operates off two primary external reference

clocks: System oscillator clock (SOSC) and RTC oscillator clock (ROSC):

• System oscillator clock is a high frequency reference clock with a frequency in

the range of 16 MHz to 32 MHz. This clock is used as a reference clock to the on-

chip PLLs which generate all the required high frequency clocks.

• RTC oscillator clock is the 32.768 kHz constant frequency, real-time clock.

2.4 Oscillators

The system oscillator, in conjunction with an external crystal or resonator, generates a

reference clock for the device. The system oscillator module supports 16-32 MHz

crystals or resonators. It also provides the option for an external input clock to

EXTAL signal directly.

The RTC oscillator is in the VBAT domain. The RTC oscillator module, in

conjunction with an external crystal, generates a 32.768 kHz real-time reference clock

for the RTC and will always be enabled and supplying clock to SRTC. This is the

default clock source.

2.5 Internal clock sources

This device is capable of generating these internal reference clocks:

• The FIRC is the fast IRC clock with nominal frequency in the range from 48 to 60

MHz. In addition, the FIRC provides a clock selection option for peripherals.

• The SIRC is the slow IRC clock with nominal frequency of 16 MHz. The SIRC

provides a clock selection option for peripherals.

• The IRC1K generates 1 kHz clock that is enabled in all modes of operation,

including all low power modes.

• The RTC OSC has the capability to provide nominal 32 kHz (not recommended

for accurate clock and normal operation) IRC in absence of the external OSC

reference clock if the VBAT domain is enabled.

NOTE

The internal oscillator is automatically multiplexed in the

clocking system when the system detects a loss of clock.

The internal oscillator will provide clocks to the same on-

Application domain (implementing ARM Cortex-A7)

chip modules as the external 32 kHz oscillator. The internal

oscillator is not precise relative to a crystal. While it will

provide a clock to the system, it generally will not be precise

enough for long-term time keeping. The internal oscillator is

anticipated to be useful for quicker start-up times and

tampering prevention, but should not be used as the exclusive

source for the 32 kHz clocks. An external 32 kHz clock

source must be used for production systems.

3 Application domain (implementing ARM Cortex-A7)

The application domain is built around an ARM Cortex-A7 processor optimized to run

nominally at 500 MHz, supported by a 32 KB L1 instruction and data cache, a large L2

cache, and an LPDDR2/LPDDR3 memory interface. The Cortex-A7 processor is a

high-performance low-power processor that implements the ARMv7-A architecture. It

uses the generic interrupt controller (GIC), generic 64-bit OS timer, FPU and the ARM

NEON SIMD engine. Additionally, all the optional debug features are included.

ring oscillator. In addition, the module’s Pseudo-Random Number Generator (PRNG)

provides accelerated processing of pseudo-random data.

3.2.2.2 Real-Time Clock (RTC)

The RTC module provides 64-bit monotonic counter with roll-over protection, 32-bit

seconds counter with roll-over protection and 32-bit alarm. This timer module is

extremely low power that allows it to operate on a backup power supply when the main

power supply is cut off. The RTC remains functional in all low power modes and can

generate an interrupt to exit any low power mode.

3.2.2.3 High Assurance Boot (HAB)

The High Assurance Boot (HAB) component of the ROM protects against the potential

threat of attackers modifying areas of code or data in programmable memory to make it

behave in an incorrect manner. The HAB also prevents attempts to gain access to

features which should not be available.

The integration of the HAB feature with the ROM code ensures that the chip does not

enter an operational state if the existing hardware security blocks have detected a

condition that may be a security threat or areas of memory deemed to be important have

been modified. The HAB uses RSA digital signatures to enforce these policies.

JTAG_ID_REG (address 0x410A_308C).

5.3 Oscillators and PLLs

5.3.1 System oscillator (SYS OSC)

The system oscillator (SYS OSC) is a crystal oscillator. The SYS OSC, in conjunction

with an external crystal or resonator, generates a reference clock for this chip. It also

provides the option for an external input clock to EXTAL signal directly.

5.3.2 Real-Time Clock Oscillator (RTC OSC)

The RTC OSC module provides the clock source for the Real-Time Clock module. The

RTC OSC module, in conjunction with an external crystal, generates a 32.678 kHz

reference clock for the RTC.

5.3.3 USB PLL

The USB PLL is embedded in the USB transceiver block. This PLL allows an exact 480

MHz to be generated from a supported reference clock of 24 MHz. The output of this

PLL is primarily used for USB operations. The USB PLL clock is also made available

as a clock source for other peripherals in the SoC.

i.MX 7ULP LDO Bypass versus LDO-enabled modes

6 i.MX 7ULP LDO Bypass versus LDO-enabled modes

i.MX 7ULP has internal low-dropout (LDO) regulators to power certain sections of the

core logic. In LDO Enabled mode, the internal LDO is used to regulate the core logic

voltage under software control. In LDO Bypass mode, the internal LDO is disabled and

the core logic supply voltage is provided externally.

The Real-time domain only supports LDO Enabled mode. The Application Domain

supports either mode. The LDO modes require specific board-level connections. LDO

Bypass vs. Enabled mode must be chosen prior to board design because the physical

connection is different.

6.1 Real-time domain LDO Enabled mode

A 1.8 V nominal voltage supply is provided externally to the VDD_PMC18_DIG0

supply. The internal LDO output is routed to VDD_PMC11_DIG0_CAP.

VDD_PMC11_DIG0_CAP must be routed back to VDD_DIG0 at the board-level with

appropriate bypass capacitors to VSS. This connection has a maximum board routing

impedance requirement. See parameter RDIG0 in Table 5.

See the i.MX 7ULP Hardware Development Guide (IMX7ULPHDG) for details on the

required bypass capacitors.

6.2 Application domain LDO Enabled mode

A 1.2 V nominal voltage supply is provided externally to the VDD_PMC12_DIG1

supply. The internal LDO output is routed to VDD_PMC11_DIG1_CAP.

VDD_PMC11_DIG1_CAP must be routed back to VDD_DIG1 at the board-level with

appropriate bypass capacitors to VSS. This connection has a maximum board routing

impedance requirement. See parameter RDIG1 in Table 5.

See the i.MX 7ULP Hardware Development Guide (IMX7ULPHDG) for details on the

required bypass capacitors.

1. VDD_PMC18, VDD18_IOREF and VDD_PTB are connected internally and, as such, must be driven from the same

source.

2. If VDD_PMC18_DIG0 is operated at 1.8 V, it should be tied to VDD_PMC18 at the board level.

3. Note that the M4 LDO is always enabled, and the VDD_PMC11_DIG0_CAP is internally regulated. There is no LDO

bypass option. VDD_PMC0_DIG0_CAP is connected to VDD_DIG0 at the board-level. The voltage observed at

VDD_PMC18_DIG0_CAP differs from the from the programmed voltage on the internal LDO because the sense point

for the LDO is on-chip.

4. The table rows under the heading "Real Time Domain (M4 domain) PMC 0 Register Configuration Requirements" define

the required voltage operating points for each operation mode. The register configurations shown must be used.

5. FBB=+/- 0.3 V is the only supported FBB voltage level on the i.MX 7ULP. CM4 FBB voltage levels are configured in the

PMC 0 Biasing Control register (BCTRL) fields FBBPLEVEL and FBBNLEVEL

6. RBB=+/-1.0 V is the only supported RBB voltage level on the i.MX 7ULP. CM4 RBB voltage levels are configured in the

PMC 0 Biasing Control register (BCTRL) fields RBBPLEVEL and RBBNLEVEL.

7. Note that the A7 LDO can be operated in LDO-enabled mode or LDO-bypass mode. In LDO-bypass mode, the internal

LDO is disabled and the voltage supply for the internal logic in the A7 domain is provided externally to

VDD_PMC12_DIG1, VDD_PMC11_DIG1_CAP, and VDD_DIG1.

8. If the MIPI DSI is used, VDD_DSI11 must be connected to VDD_DIG1 at board level. If MIPI DSI is not used,

VDD_DSI11 can be connected to ground through a 10 KΩ resistor.

9. CA7 domain HSRUN is limited to 8760 power-on hours over the lifetime of the product. The total power-on hours

includes all CA7 power modes except VLLS mode and VBAT mode in which the CA7 domain is internally power-gated.

10. FBB=+/- 0.3 V is the only supported FBB voltage level on the i.MX 7ULP. CA7 FBB voltage levels are configured in the

PMC 1 Biasing Control register (BCTRL) fields FBBPLEVEL and FBBNLEVEL.

11. To minimize power consumption in VLPS mode, configure PMC1 register bit SRAMCTRL[SRAM_STDY] to

RETENTION mode.

12. In VLLS mode, VDD_DIG1 is internally power gated to the application domain logic. VDD_DIG1 must remain powered if

the following supplies are powered: VDD_USB18, VDD_USB33, VDD_DSI18 and VDD_DSI11. If the USB and DSI

supplies are not used/powered, VDD_DIG1 can be turned off at the board level.

13. Note that the A7 LDO can be operated in LDO-enabled mode or LDO-bypass mode. In LDO-enabled mode, the voltage

supply to the internal logic in the A7 domain is regulated by the internal LDO.

14. When using LDO-enabled mode, the voltage at the associated *_CAP ball differs from the programmed voltage

because the sense point for the LDO is on-chip.

15. To achieve minimum power consumption, VDD_PTA, VDD_PTB, VDD_PTC, VDD_PTE, and VDD_PTF must remain

powered in all modes except BAT mode.

16. VDD_PTA must be powered during a power-on reset (POR) for the SMC0 Mode register (MR) BOOTCFG field to

properly latch the boot configuration from the PTA signals (GPIO Boot mode).

17. VDD_ANA33 must be shorted to VDD_PTA at the board level.

18. VDD_PTF must be powered during a power-on reset (POR) for the SMC1 Mode register (MR) BOOTCFG field to

properly latch the boot configuration from the PTF signals (GPIO Boot mode). VDD_PTF must also remain powered

during all A7 power modes except for BAT mode.

19. VDD_DDR must remain powered while VDD18_DDR is powered.

20. The 7ULP USB PHY provides two options for reporting VBUS valid back to the USB controller:

• A programmable internal VBUS_VALID comparator (the default option), or

• An alternate VBUS_VALID_3V detector that will report VBUS valid for voltages above 3 V

38

System specifications

USBPHY_USB1_VBUS_DETECTn[VBUSVALID_SEL] selects which option is used. If the VBUS_VALID comparator is

used, USBPHY_USB1_VBUS_DETECTn[VBUSVALID_THRESH] determines the threshold voltage for a valid VBUS.

The programmable range is 4.0V to 4.4V (default).

21. The 7ULP USB PHY provides two options for reporting VBUS valid back to the USB controller:

• A programmable internal VBUS_VALID comparator (the default option), or

• An alternate VBUS_VALID_3V detector that will report VBUS valid for voltages above 3 V.

USBPHY_USB1_VBUS_DETECTn[VBUSVALID_SEL] selects which option is used. If the VBUS_VALID_3V detector

is used, the detector voltage is not programmable.

7.1.6 Estimated maximum supply currents

This table represents the estimated maximum current on the power supply rails and

should be used for power supply selection. The data below is based on design

simulation as well as measured data. Note that some of the data in the table is based

on internal companion regulator limits and not actual use cases. Maximum currents

are higher by far than the average power consumption of typical use cases.

7.2.2 Core, platform, and system bus clock frequency limitations

The clock ratio restrictions among the core, platform and IP bus clocks are listed as

follows:

• A7 core clock frequency is higher than A7 platform clock frequency.

• Clock ratio must be integers between A7 fast platform (NIC0) and A7 slow

platform (NIC1).

NOTE

Use A7 SPLL for core clock and A7 APLL for

DDR/NIC clocks.

• Clock ratio must be integers between A7 slow platform and A7 system IP bus.

• Clock ratio must be integers between M4 core/platform and M4 system IP bus.

• M4 slow clock must be slower and an integer division of M4 system IP bus.

• A7 Slow platform (NIC1) clock frequency should be higher than A7 System IP

bus clock (NIC1_BUS clock).

The following tables show examples of various allowable clock frequencies for the

cores, platforms, system bus, and DDR in different operating modes.

NOTE

The frequencies stated in these tables are typical

configuration and maximum frequencies in a particular

mode. However, since there are multiple clock dividers,

different clock ratios can be achieved.

7.2.5 Audio tunable clock

For audio applications where the data stream is coming from a remote source, the

device has to locally tune a clock signal to match the remote system clock. The

Auxiliary PLL, which provides the clock for master audio, has synchronization logic to

support on-the-fly configuration changes. This allows the device to generate a tunable

clock for audio stream. The clock from one of the Auxiliary PLLs (PLL1) can be

divided by the post-dividers in analog and also the dividers in SCG module. The

divided tunable clock generated should meet the following requirement:

• Output center frequency of 12.288 MHz or 11.2896 MHz

• Tunable range of 1000 ppm

• Tunable resolution of 1 ppm

All processor bus timings are synchronous; input setup/hold and output delay are

given in respect to the rising edge of a reference clock, FB_CLK. The FB_CLK

frequency may be the same as the internal system bus frequency or an integer divider

of that frequency.

The following timing parameters indicate when data is latched or driven onto the

external bus, relative to the Flexbus output clock (FB_CLK). All other timing

relationships can be derived from these values.

1. The master mode I²C deasserts ACK of an address byte simultaneously with the falling edge of SCL. If no slaves

acknowledge this address byte, then a negative hold time can result, depending on the edge rates of the SDA and

SCL lines.

2. The maximum tHD; DAT must be met only if the device does not stretch the LOW period (tLOW) of the SCL signal.

3. Input signal Slew = 10 ns and Output Load = 50 pF

4. Set-up time in slave-transmitter mode is 1 IPBus clock period, if the TX FIFO is empty.

5. A Fast mode I²C bus device can be used in a Standard mode I2C bus system, but the requirement t_{SU; DAT}≥ 250 ns

must then be met. This is automatically the case if the device does not stretch the LOW period of the SCL signal. If

such a device does stretch the LOW period of the SCL signal, then it must output the next data bit to the SDA line t_rmax

+ t_{SU; DAT}= 1000 + 250 = 1250 ns (according to the Standard mode I²C bus specification) before the SCL line is

released.

1. It is recommended to operate the DAC in the output voltage range between 0.15 V and (VDD_ANA18 - 0.15 V) for

best accuracy. Linearity of the output voltage outside this range will be affected as current load increases.

2. When VREFH_ANA18 is selected as the reference (DAC_CR[DACRFS]=1b).

3. When the internal 1.2 V source is selected as the reference (DAC_CR[DACRFS]=1b).

4. The DAC output remains within 0.5 LSB of the final measured value for digital input code change. Noise on the

power supply can cause this performance to degrade to 1 LSB. This parameter represents both rising edge and

falling edge settling time.

5. Time for the DAC output to transition from 10% to 90% signal amplitude (rising edge or falling edge).

6. PSRR=20*log{∆VDD_ANA18 /∆VDAC_OUT}

7. If two DACs are used and sharing the same VREFH.
