Product details
Overview
MSPM0L1305SRTRR from Texas Instruments is a 32-bit Arm® Cortex®-M0+ microcontroller operating at up to 32 MHz, featuring 32 KB flash, 4 KB SRAM, and integrated analog peripherals including a 12-bit 1.68-Msps ADC with 10 external channels, two zero-drift chopper op-amps, and a high-speed comparator with 8-bit reference DAC - deployed in battery-powered smart metering and portable power delivery systems.
For engineers reviewing the MSPM0L1305SRTRR datasheet, MSPM0L1305SRTRR pinout, MSPM0L1305SRTRR application, or MSPM0L1305SRTRR equivalent, key selection criteria include its 16-pin WQFN (RTR) package, –40°C to 125°C extended temperature rating, 1.62–3.6 V supply range, ultra-low-power STANDBY mode (1.0 µA), and configurable analog signal routing between ADC, OPAs, COMP, and DAC.
Technical Context
The MSPM0L1305SRTRR implements an enhanced Arm Cortex-M0+ core with on-chip SYSOSC (±1.2% accuracy) eliminating external crystals, and supports intelligent low-power operation via RUN (71 µA/MHz), STOP (44 µA @ 32 kHz), STANDBY (1.0 µA with 32-kHz timer active), and SHUTDOWN (61 nA) modes. Its analog subsystem enables direct sensor-to-digital conversion with programmable gain (1–32×) and internal voltage references (1.4 V or 2.5 V).
Digital integration includes two UARTs (one supporting LIN/IrDA/DALI/Manchester), two I²C interfaces (one FM+, SMBus/PMBus-capable), one SPI (up to 16 Mbit/s), four 16-bit timers (8 PWM channels total), 3-channel DMA, and event fabric signaling - all accessible in STANDBY mode for responsive wake-up and real-time control.
Key Specifications
