Product details
Overview
M0G3505QRGZRQ1 from Texas Instruments is an automotive-grade Arm® Cortex®-M0+ microcontroller with CAN-FD interface, 32KB flash, 16KB SRAM, dual 12-bit 4Msps ADCs (17-channel), and ASIL-B functional safety certification for body electronics and gateway applications.
For engineers reviewing the M0G3505QRGZRQ1 datasheet, M0G3505QRGZRQ1 pinout, M0G3505QRGZRQ1 application, or M0G3505QRGZRQ1 equivalent, this page delivers verified technical context, package-specific pin functions, low-power mode trade-offs, CAN-FD timing compliance, and AEC-Q100 Grade 1 qualification details essential for automotive ECU design.
Technical Context
The M0G3505QRGZRQ1 integrates a memory protection unit (MPU), 7-channel DMA, math accelerator (DIV/SQRT/MAC/TRIG), and dual 16-bit advanced timers with deadband support - enabling real-time motor control and PWM generation in STANDBY mode at 4MHz. Its analog subsystem includes two zero-drift chopper op-amps (0.5µV/°C drift), three high-speed comparators (32ns propagation), and programmable analog routing between ADC, DAC, OPA, COMP, and GPAMP.
Clock architecture combines internal SYSOSC (±1.2% accuracy), PLL (up to 80MHz), LFXT/LFOSC (±3%), and HFXT (4–48MHz) sources. Power management supports 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).
