It delivers functional safety support up to ASIL B and targets body electronics, gateway, and motor control modules requiring integrated analog, low-power operation, and robust communication.

For engineers reviewing the M0G3105QRHBRQ1 datasheet, M0G3105QRHBRQ1 pinout, M0G3105QRHBRQ1 application, or M0G3105QRHBRQ1 equivalent, key selection criteria include its 32-pin VQFN (5mm × 5mm) package, CAN-FD + four UARTs + two I²C + two SPI interfaces, ultra-low-power STANDBY mode (1.5µA), and hardware ECC/parity for safety-critical firmware and data integrity.

Technical Context

The M0G3105QRHBRQ1 implements an Arm Cortex-M0+ core at up to 80MHz with MPU, integrated 7-channel DMA, and dual independent 12-bit ADCs supporting simultaneous sampling and hardware averaging for 14-bit effective resolution at 250ksps. Its clock system combines SYSOSC (±1.2%), PLL, HFXT/LFXT, and LFOSC (±3%) for flexible timing across operating modes.

Safety architecture includes ISO 26262 ASIL B certification by TÜV, built-in ECC on flash and parity on SRAM, CRC-16/32, TRNG, and AES-128/256 encryption. Power management supports five low-power states - RUN (101µA/MHz), SLEEP (40µA/MHz), STOP (190µA @4MHz), STANDBY (1.5µA with RTC/SRAM retention), and SHUTDOWN (80nA with IO wake-up).

FAQ

What is the maximum operating frequency of the M0G3105QRHBRQ1?

The M0G3105QRHBRQ1 features an Arm Cortex-M0+ CPU with a maximum operating frequency of 80MHz, achieved via its internal PLL. This frequency is fully supported across the specified operating temperature range (–40°C to +125°C) and supply voltage (1.62V to 3.6V), enabling deterministic real-time control in automotive applications such as motor drivers and gateway nodes. The M0G3105QRHBRQ1 maintains timing compliance under all recommended conditions per its datasheet specifications.

Does the M0G3105QRHBRQ1 support CAN-FD, and what data rates does it achieve?

Yes, the M0G3105QRHBRQ1 integrates a Controller Area Network interface compliant with both CAN 2.0 A/B and CAN-FD protocols. It supports bit rates up to 5Mbps in FD mode and up to 1Mbps in classical CAN mode. The peripheral includes dedicated TX/RX pins (PA26/PA27), message RAM buffering, and error handling logic - all validated for AEC-Q100 Grade 1 operation. This makes the M0G3105QRHBRQ1 suitable for high-throughput vehicle network gateways and domain controllers.

How many analog input channels does the M0G3105QRHBRQ1 support, and what is its ADC resolution?

The M0G3105QRHBRQ1 integrates two simultaneous-sampling 12-bit analog-to-digital converters (ADCs) with up to 11 external input channels. At 250ksps, hardware averaging yields 14-bit effective resolution. Each ADC supports programmable sampling windows, window comparison, and direct memory access via the 7-channel DMA controller - enabling precise current sensing, battery monitoring, and environmental sensing in automotive subsystems without external signal conditioning.

What low-power modes are available on the M0G3105QRHBRQ1, and what is the lowest current draw?

The M0G3105QRHBRQ1 supports five low-power modes: RUN, SLEEP, STOP, STANDBY, and SHUTDOWN. Its lowest active-retention mode is STANDBY, drawing just 1.5µA while retaining RTC operation, SRAM contents, CPU register state, and interrupt wake-up capability. In SHUTDOWN mode, current drops to 80nA with IO retention and wake-up enabled - meeting stringent automotive off-mode battery drain requirements for modules like door handles and occupancy sensors.

Is the M0G3105QRHBRQ1 qualified for automotive use, and what safety certifications does it hold?

Yes, the M0G3105QRHBRQ1 is AEC-Q100 Grade 1 qualified (–40°C to +125°C) and ISO 26262 certified up to ASIL B by TÜV. It includes hardware-level safety mechanisms: flash ECC, SRAM parity, CRC accelerators, lockstep-capable peripherals, and systematic development documentation. These features collectively support functional safety requirements for automotive body electronics, gateway, and comfort systems - verified across silicon, firmware, and toolchain layers per TI's safety manual for the MSPM0G310x-Q1 family.
