Product details
Overview
M0L1305QDGS20RQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive-qualified 32-bit Arm® Cortex®-M0+ microcontroller operating up to 32 MHz, with 32 KB flash, 4 KB SRAM, a 12-bit 1.68-Msps ADC (8 external channels), two zero-drift chopper op-amps, and integrated temperature sensor - deployed in steering wheel systems and door handle modules.
For engineers reviewing the M0L1305QDGS20RQ1 datasheet, M0L1305QDGS20RQ1 pinout, M0L1305QDGS20RQ1 application, or M0L1305QDGS20RQ1 equivalent, key selection criteria include its 20-pin VSSOP package, -40°C to +125°C operation, 1.62–3.6 V supply range, low-power STANDBY mode (1.0 µA), and functional safety documentation support.
Technical Context
The M0L1305QDGS20RQ1 implements an Arm Cortex-M0+ core with on-chip SYSOSC (±1.2% accuracy, 4–32 MHz) and LFOSC (±3%, 32 kHz), enabling crystal-free operation in automotive body electronics. Its analog subsystem integrates programmable gain (1–32×) into both OPA0 and OPA1, with dedicated ADC input routing and configurable internal VREF (1.4 V or 2.5 V).
Digital peripherals include two UARTs (one LIN-capable), two I²C interfaces (one FM+, 1 Mbit/s), one SPI (16 Mbit/s), four 16-bit timers supporting 8 PWM channels, and a 3-channel DMA - all accessible via a hierarchical peripheral bus architecture (PD0/PD1) with event fabric signaling for low-latency inter-peripheral communication.
