Product details
Overview
M0L1306QDGS32RQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive-qualified Arm® Cortex®-M0+ microcontroller operating up to 32 MHz, with 64 KB flash, 4 KB SRAM, a 12-bit 1.68-Msps ADC (10 external channels), two zero-drift chopper op-amps, and integrated 8-bit reference DAC for comparator use - deployed in body electronics modules requiring robust analog sensing and low-power operation across –40°C to +125°C.
For engineers reviewing the M0L1306QDGS32RQ1 datasheet, M0L1306QDGS32RQ1 pinout, M0L1306QDGS32RQ1 application, or M0L1306QDGS32RQ1 equivalent, this page delivers verified functional safety–managed MCU specifications, VSSOP-32 package I/O mapping, automotive-grade power sequencing details, and validated alternative options for gateway and motor control designs.
Technical Context
The M0L1306QDGS32RQ1 implements a single-core Arm Cortex-M0+ CPU with tightly coupled peripherals including a 3-channel DMA, event fabric signaling, and four 16-bit timers supporting 8 PWM outputs - all accessible via AHB and ULP peripheral buses with configurable clock domains (SYSOSC ±1.2%, LFOSC ±3%).
Analog subsystem integration includes programmable connections between ADC, OPAs, COMP, and DAC; dual chopper op-amps with 0.5-µV/°C drift and 1–32× gain; and a high-speed comparator with 32-ns propagation delay and internal 8-bit reference DAC - enabling closed-loop sensor conditioning without external components.
