Texas Instruments M0G3506QPTRQ1

Overview

M0G3506QPTRQ1 from Texas Instruments is an automotive-grade Arm® Cortex®-M0+ microcontroller operating at up to 80MHz, featuring 64KB flash with ECC, 32KB SRAM with hardware parity, and integrated CAN-FD interface. It delivers ASIL B functional safety compliance, operates from –40°C to 125°C, and supports 1.62V–3.6V supply for body electronics and gateway applications.

For engineers reviewing the M0G3506QPTRQ1 datasheet, M0G3506QPTRQ1 pinout, M0G3506QPTRQ1 application, or M0G3506QPTRQ1 equivalent, key selection criteria include CAN-FD timing accuracy, dual 12-bit 4Msps ADC channel count, low-power STOP/STANDBY current (190µA at 4MHz / 1.5µA), and AEC-Q100 Grade 1 qualification.

Technical Context

The M0G3506QPTRQ1 implements a memory protection unit (MPU) and 7-channel DMA for deterministic real-time control in automotive subsystems. Its analog subsystem integrates two simultaneous-sampling 12-bit ADCs (4Msps), one 12-bit DAC (1Msps), three high-speed comparators (32ns propagation delay), and two zero-drift chopper op-amps (0.5µV/°C drift).

Digital peripherals include two 16-bit advanced timers with deadband support (up to 12 PWM channels), five general-purpose timers (including QEI-capable and STANDBY-mode variants), and dual window-watchdog timers. Clocking combines SYSOSC (±1.2%), PLL (80MHz), LFXT (32kHz), and HFXT (4–48MHz) sources for robust timing across operating modes.

FAQ

What is the maximum operating frequency and core architecture of the M0G3506QPTRQ1?

The M0G3506QPTRQ1 features an Arm® Cortex®-M0+ CPU with memory protection unit, operating at up to 80MHz. This frequency is achieved via internal PLL driven by SYSOSC or external HFXT, and is validated across the full –40°C to 125°C temperature range. The M0G3506QPTRQ1 core executes Thumb-2 instructions and supports deterministic interrupt latency critical for automotive real-time tasks.

Does the M0G3506QPTRQ1 support CAN-FD, and what are its timing capabilities?

Yes, the M0G3506QPTRQ1 includes a fully compliant Controller Area Network interface supporting both CAN 2.0 A/B and CAN-FD protocols. It achieves bit rates up to 5Mbps in FD mode with programmable sample points and synchronization jump width. The CAN module integrates TX/RX FIFOs, error counters, and loopback testing-enabling robust diagnostics in automotive networks without external transceivers.

How much flash and SRAM does the M0G3506QPTRQ1 provide, and what data integrity features are included?

The M0G3506QPTRQ1 provides 64KB of embedded flash memory with built-in error correction code (ECC) and 32KB of SRAM with hardware parity checking. ECC detects and corrects single-bit errors and detects double-bit errors in flash, while SRAM parity protects against soft errors-both essential for ASIL B compliance and long-term reliability in automotive environments.

What low-power modes are available on the M0G3506QPTRQ1, and what is the lowest current consumption?

The M0G3506QPTRQ1 supports RUN, SLEEP, STOP, STANDBY, and SHUTDOWN modes. Minimum current is 80nA in SHUTDOWN mode with IO retention and wake-up capability. STANDBY draws 1.5µA while retaining RTC, SRAM, CPU state, and registers-ideal for always-on vehicle modules requiring sub-second wake latency.

Is the M0G3506QPTRQ1 qualified for automotive use, and what certifications does it hold?

Yes, the M0G3506QPTRQ1 is AEC-Q100 Grade 1 qualified (–40°C to 125°C) and ISO 26262 certified up to ASIL B by TÜV. It includes documentation for functional safety system design, hardware integrity analysis, and systematic capability evidence-enabling direct integration into ASIL B automotive subsystems without additional component-level certification effort.
