Overview
M0G3506QRGZRQ1 from Texas Instruments is an automotive-grade 32-bit Arm® Cortex®-M0+ microcontroller with CAN-FD interface, 64KB flash, 32KB SRAM with hardware parity, dual 12-bit 4-Msps ADCs (17-channel), and ASIL B functional safety certification for body electronics and gateway applications.
For engineers reviewing the M0G3506QRGZRQ1 datasheet, M0G3506QRGZRQ1 pinout, M0G3506QRGZRQ1 application, or M0G3506QRGZRQ1 equivalent, this page delivers verified technical context, package-specific pin functions, real-world automotive use cases, and validated alternative options aligned to AEC-Q100 Grade 1 and ISO 26262 system design requirements.
Technical Context
The M0G3506QRGZRQ1 integrates a memory protection unit (MPU), 7-channel DMA, math accelerator (DIV/SQRT/MAC/TRIG), and dual high-speed analog subsystems: two simultaneous-sampling ADCs with hardware averaging enabling 14-bit effective resolution at 250ksps, and three comparators each with integrated 8-bit reference DACs.
Its clock system combines internal SYSOSC (±1.2% accuracy), PLL (up to 80MHz), LFXT/LFOSC, and HFXT support; power management includes five low-power modes-RUN (101µA/MHz), SLEEP (40µA/MHz), STOP (190µA @4MHz), STANDBY (1.5µA with RTC/SRAM retention), and SHUTDOWN (80nA with IO wake-up).
