Texas Instruments MSPM0L1305TRGER

Overview

MSPM0L1305TRGER from Texas Instruments is an ultra-low-power 32-bit Arm® Cortex®-M0+ microcontroller operating up to 32 MHz, featuring 32 KB flash, 4 KB SRAM, and a 12-bit 1.68-Msps ADC with 10 external channels-designed for battery-powered sensor monitoring and power management in industrial edge nodes.

For engineers reviewing the MSPM0L1305TRGER datasheet, MSPM0L1305TRGER pinout, MSPM0L1305TRGER application, or MSPM0L1305TRGER equivalent, key selection criteria include its –40°C to 125°C extended temperature rating, 1.62–3.6 V supply range, dual zero-drift OPAs with programmable gain (1–32×), STANDBY mode consuming only 1.0 µA with full SRAM retention, and integrated 8-bit reference DAC for comparator operation.

Technical Context

The MSPM0L1305TRGER implements a single-core Arm Cortex-M0+ CPU with on-chip SYSOSC (±1.2% accuracy) eliminating external crystals, and supports multiple low-power modes including SHUTDOWN (61 nA with IO wakeup). Its analog subsystem integrates two chopper-stabilized operational amplifiers (0.5 µV/°C drift, 6 pA input bias), one GPAMP, one high-speed comparator (32 ns propagation delay), and configurable analog routing between ADC, OPAs, COMP, and DAC.

Digital peripherals include four 16-bit timers (8 PWM channels total), 3-channel DMA, event fabric signaling, two UARTs (one supporting LIN/IrDA/DALI), two I²C interfaces (one FM+, 1 Mbit/s), and one SPI (up to 16 Mbit/s)-all operable in STANDBY mode with fast 3.2 µs wakeup from 32 MHz clock.
