Overview
M0G3105QDGS28RQ1 from Texas Instruments is an automotive-grade Arm® Cortex®-M0+ microcontroller operating at up to 80MHz, featuring 32KB flash with ECC, 16KB SRAM with parity, CAN-FD interface, dual 12-bit 4Msps ADCs (11-channel), and AEC-Q100 Grade 1 qualification for use in body electronics and gateway modules.
For engineers reviewing the M0G3105QDGS28RQ1 datasheet, M0G3105QDGS28RQ1 pinout, M0G3105QDGS28RQ1 application, or M0G3105QDGS28RQ1 equivalent, this page delivers verified technical context, package-specific pin mapping, functional safety details (ASIL B), low-power operation down to 1.5µA in STANDBY, and automotive-qualified analog/digital integration - all confirmed for the 28-pin VSSOP variant.
Technical Context
The M0G3105QDGS28RQ1 implements a memory protection unit (MPU) and 7-channel DMA for deterministic real-time control, with dual ADCs supporting simultaneous sampling and hardware averaging for 14-bit effective resolution at 250ksps. Its clock system integrates SYSOSC (±1.2%), PLL (up to 80MHz), and dual crystal oscillators (HFXT/LFXT).
Functional safety is embedded at silicon level: ISO 26262 ASIL B certification by TÜV covers systematic capability and hardware integrity, while safety documentation supports system-level design. The device operates across –40°C to 125°C and 1.62V–3.6V, with five low-power modes including STANDBY (1.5µA, RTC + SRAM retained) and SHUTDOWN (80nA, IO wake-up capable).
