Product details
Overview
M0G3505QDGS28RQ1 from Texas Instruments is an automotive-grade Arm® Cortex®-M0+ microcontroller with CAN-FD interface, 32KB flash, 16KB SRAM, dual 12-bit 4Msps ADCs (11-channel), and operation from –40°C to 125°C at 1.62V–3.6V supply. It integrates two zero-drift op-amps, three comparators, one 12-bit DAC, and supports ASIL B functional safety per ISO 26262 for body electronics and motor control.
For engineers reviewing the M0G3505QDGS28RQ1 datasheet, M0G3505QDGS28RQ1 pinout, M0G3505QDGS28RQ1 application, or M0G3505QDGS28RQ1 equivalent, key selection criteria include its 28-pin VSSOP package, CAN-FD + UART/I²C/SPI interfaces, ultra-low-power STANDBY mode (1.5µA), AEC-Q100 Grade 1 qualification, and integrated analog signal chain for sensor conditioning and closed-loop control.
Technical Context
The M0G3505QDGS28RQ1 implements a single-core Arm Cortex-M0+ CPU running up to 80MHz with MPU, 7-channel DMA, and math accelerator supporting DIV/SQRT/MAC/TRIG. Its analog subsystem includes programmable analog routing between ADCs, OPAs, COMP, DAC, and VREF, enabling flexible sensor front-end configurations without external components.
Digital peripherals include two 16-bit advanced timers (12 PWM channels with deadband), five general-purpose timers (including QEI-capable and STANDBY-mode timers), two window-watchdog timers, RTC with calendar, and four UARTs - three of which retain functionality in STANDBY mode. Clocking supports internal SYSOSC (±1.2%), PLL, HFXT/LFXT, and LFOSC (±3%).
