Product details
Overview
M0G3505QPTRQ1 from Texas Instruments is an automotive-grade 32-bit Arm® Cortex®-M0+ microcontroller with CAN-FD interface, 32KB flash, 16KB SRAM, and operation up to 80MHz. It integrates dual 12-bit 4Msps ADCs (16-channel), one 12-bit DAC, three high-speed comparators, two zero-drift op-amps, and supports ASIL B functional safety for body electronics and gateway applications.
For engineers reviewing the M0G3505QPTRQ1 datasheet, M0G3505QPTRQ1 pinout, M0G3505QPTRQ1 application, or M0G3505QPTRQ1 equivalent, key selection criteria include AEC-Q100 Grade 1 qualification, 48-pin LQFP package with 44 GPIOs, CAN-FD + four UARTs + two I²C + two SPI interfaces, and ultra-low-power STANDBY mode (1.5µA with RTC and SRAM retention).
Technical Context
The M0G3505QPTRQ1 implements a memory protection unit (MPU) and 7-channel DMA controller to support deterministic real-time control in automotive subsystems. Its analog subsystem enables simultaneous sampling across two ADCs with hardware averaging for 14-bit effective resolution at 250ksps, plus configurable internal VREF (1.4V/2.5V) and programmable gain (up to 32×) on OPA0/OPA1.
Digital peripherals include two 16-bit advanced timers with deadband and complementary outputs (12 PWM channels), five general-purpose timers (one QEI-capable, two STANDBY-wakeup capable), and dual window-watchdog timers. The clock system combines SYSOSC (±1.2%), PLL (80MHz), LFXT/LFOSC, and HFXT for robust timing across temperature (–40°C to 125°C) and supply (1.62V–3.6V).

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| M0G3506QPTRQ1 | 64KB flash, 32KB SRAM, same package/peripherals - doubles program memory and RAM capacity without layout change. | Required for larger firmware (e.g., OTA update stack + diagnostics + bootloader) or complex sensor fusion algorithms. | Select when firmware size exceeds 32KB or real-time multitasking requires >16KB heap/stack space. |
| SPC560B50L5 | Power Architecture e200z0h core, 64MHz, 512KB flash, 48KB RAM, CAN-FD, but no integrated high-speed ADC or op-amps. | Better suited for gateway routing tasks; lacks on-chip analog front-end for direct sensor interfacing. | Choose for pure CAN-FD routing/bridging where external ADCs/op-amps are already present; avoid if analog integration is required. |

The M0G3505QPTRQ1 features an Arm Cortex-M0+ 32-bit CPU core with a maximum operating frequency of 80MHz. It includes a memory protection unit (MPU) and operates across the full automotive temperature range (–40°C to 125°C). This core delivers deterministic real-time performance while maintaining ultra-low power consumption - essential for automotive body control and gateway functions where both speed and energy efficiency are critical. The M0G3505QPTRQ1 uses this architecture to execute safety-critical firmware with predictable timing behavior.
Does the M0G3505QPTRQ1 support CAN-FD, and what are its data rate capabilities?
Yes, the M0G3505QPTRQ1 integrates a fully compliant CAN-FD controller supporting both CAN 2.0 A/B and CAN-FD protocols. It achieves up to 1Mbps in nominal phase and 5Mbps in fast data phase. The peripheral includes dedicated TX/RX pins (PA12/PA13), built-in message RAM, and error counters - enabling high-bandwidth communication between vehicle domains without external protocol translation. This capability is directly leveraged in M0G3505QPTRQ1-based gateway and body control designs.
How many analog-to-digital converter (ADC) channels does the M0G3505QPTRQ1 support, and what is their resolution and speed?
The M0G3505QPTRQ1 integrates two independent 12-bit analog-to-digital converters (ADC0 and ADC1), each supporting up to 16 external input channels. They operate at up to 4Msps sampling rate with simultaneous sampling capability. With hardware averaging, effective resolution reaches 14 bits at 250ksps - ideal for precise current sensing, battery monitoring, and position feedback in automotive applications. These ADCs are central to the M0G3505QPTRQ1's role in sensor-rich ECUs.
What low-power modes are available on the M0G3505QPTRQ1, and what is the lowest current draw with RTC active?
The M0G3505QPTRQ1 offers five low-power modes: RUN, SLEEP, STOP, STANDBY, and SHUTDOWN. In STANDBY mode, it draws just 1.5µA while retaining RTC operation, SRAM contents, CPU state, and register values - powered by the 32kHz LFXT oscillator. This enables always-on functionality in modules like door handles and occupancy sensors. The M0G3505QPTRQ1 achieves this ultra-low quiescent current without sacrificing wake-up responsiveness or data retention.
Is the M0G3505QPTRQ1 qualified for automotive use, and what safety certifications does it hold?
Yes, the M0G3505QPTRQ1 is AEC-Q100 Grade 1 qualified (–40°C to 125°C) and ISO 26262 certified by TÜV up to ASIL B for both systematic capability and hardware integrity. Documentation supporting functional safety system design is provided by Texas Instruments.
