Product details
Overview
MSPM0L1304TDGS28R 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 support for –40°C to 125°C operation. It targets battery-powered sensor nodes and power management subsystems requiring high analog integration and sub-µA shutdown current.
For engineers reviewing the MSPM0L1304TDGS28R datasheet, MSPM0L1304TDGS28R pinout, MSPM0L1304TDGS28R application, or MSPM0L1304TDGS28R equivalent, key selection considerations include its 28-pin VSSOP package, dual I²C/SPI/UART interfaces with STANDBY wakeup, programmable analog interconnects (ADC↔OPA↔COMP↔DAC), and verified 61 nA SHUTDOWN mode with IO wakeup capability.
Technical Context
The MSPM0L1304TDGS28R implements a single-core Arm Cortex-M0+ CPU with integrated SYSOSC (±1.2% accuracy) and LFOSC (±3%), eliminating need for external crystals. Its peripheral bus architecture separates ULPCLK and MCLK domains to enable concurrent low-power analog operation and digital processing.
Analog subsystem includes configurable VREF (1.4 V or 2.5 V), COMP0 with integrated 8-bit DAC, GPAMP, and programmable gain OPA stages (1×–32×). Digital intelligence is delivered via 3-channel DMA, event fabric, four 16-bit timers (8 PWM channels), and windowed watchdog - all functional in STANDBY mode.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSPM0L1305TDGS28R | 32 KB flash, 4 KB SRAM - double memory capacity with identical peripheral set and package. | Required for applications needing larger firmware (e.g., BLE stack + sensor fusion) or extended calibration tables. | Select when firmware size exceeds 16 KB or future-proofing for feature expansion is needed. |
| MSPM0L1304TRHB | Same flash/SRAM but 32-pin VQFN (5 mm × 5 mm) - adds 4 GPIOs and removes 5-V-tolerant I/O capability. | Suitable for space-constrained PCBs where extra I/O is needed and 5-V interfacing is unnecessary. | Choose for higher pin count and better thermal dissipation; avoid if interfacing with 5-V sensors or buses. |
Compared with MSPM0L1305TDGS28R, the MSPM0L1304TDGS28R trades memory headroom for lower cost and smaller code footprint; versus MSPM0L1304TRHB, it sacrifices 4 GPIOs and thermal pad access for guaranteed 5-V-tolerant I/O compatibility in mixed-voltage systems.
