Product details
Overview
MSPM0L1304SRHBR from Texas Instruments is an ultra-low-power 32-bit Arm® Cortex®-M0+ microcontroller operating up to 32 MHz, featuring 16 KB flash, 2 KB SRAM, a 12-bit 1.68-Msps ADC with 10 external channels, two zero-drift chopper op-amps (0.5 µV/°C drift), and integrated temperature sensor - deployed in battery-powered smart sensors and portable power management systems.
For engineers reviewing the MSPM0L1304SRHBR datasheet, MSPM0L1304SRHBR pinout, MSPM0L1304SRHBR application, or MSPM0L1304SRHBR equivalent, key selection criteria include its 32-pin VQFN (RHB) package, -40°C to 125°C extended temperature rating, 1.62–3.6 V supply range, STANDBY mode current of 1.0 µA with full SRAM retention, and dual UART/I²C/SPI interfaces supporting LIN, SMBus, and PMBus protocols.
Technical Context
The MSPM0L1304SRHBR implements a single-core Arm Cortex-M0+ CPU with tightly coupled peripherals including a 3-channel DMA, event fabric for low-latency signal routing, and four 16-bit timers supporting 8 PWM outputs. Its analog subsystem integrates ADC, COMP, GPAMP, and two OPA blocks with programmable gain (1–32×) and configurable internal VREF (1.4 V or 2.5 V).
Power management is optimized across four low-power modes: RUN (71 µA/MHz), STOP (151 µA @ 4 MHz), STANDBY (1.0 µA with 32-kHz timer active and 3.2 µs wakeup), and SHUTDOWN (61 nA with IO wake capability). Clocking uses internal SYSOSC (±1.2% accuracy, 4–32 MHz) and LFOSC (±3%, 32 kHz), eliminating external crystals.
