Overview
MSPM0L1304TRHBR 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 sensing - deployed in battery-powered power delivery and smart metering systems.
For engineers reviewing the MSPM0L1304TRHBR datasheet, MSPM0L1304TRHBR pinout, MSPM0L1304TRHBR application, or MSPM0L1304TRHBR 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 MSPM0L1304TRHBR integrates a high-accuracy ±1.2% internal SYSOSC (4–32 MHz) and ±3% LFOSC (32 kHz), eliminating external crystals. Its analog subsystem enables programmable connections between ADC, OPAs, COMP, and DAC, supporting sensor signal conditioning and closed-loop control without external components.
Digital intelligence includes a 3-channel DMA, event fabric for low-latency peripheral triggering, four 16-bit timers (8 PWM channels total), and a windowed watchdog timer - all operable in STANDBY mode with 3.2 µs wakeup to 32 MHz, enabling responsive yet energy-efficient real-time operation.

FAQ
What is the maximum operating frequency of the MSPM0L1304TRHBR?
The MSPM0L1304TRHBR features an Arm Cortex-M0+ CPU with a maximum operating frequency of 32 MHz, enabled by its internal ±1.2% accuracy SYSOSC. This frequency is fully supported across the entire specified operating temperature range (–40°C to 125°C) and supply voltage range (1.62 V to 3.6 V), ensuring deterministic real-time performance without external clock sources.
Does the MSPM0L1304TRHBR support hardware debugging?
Yes, the MSPM0L1304TRHBR supports 2-pin Serial Wire Debug (SWD) via dedicated SWCLK (Pin 24) and SWDIO (Pin 23) pins. This interface enables full programming, breakpoint-based debugging, real-time variable inspection, and trace capabilities using standard TI tools like Code Composer Studio and third-party JTAG/SWD debuggers compatible with ARM CoreSight.
How many analog input channels does the MSPM0L1304TRHBR ADC support?
The MSPM0L1304TRHBR integrates a single 12-bit, 1.68-Msps ADC supporting up to 10 external analog input channels (A0–A9), mapped to GPIO pins PA27 through PA19. These channels are accessible simultaneously via hardware-triggered sampling and support configurable internal references (1.4 V or 2.5 V), enabling precise multi-sensor acquisition in compact designs.
What low-power modes are available on the MSPM0L1304TRHBR?
The MSPM0L1304TRHBR offers four configurable low-power modes: RUN (71 µA/MHz), STOP (151 µA at 4 MHz), STANDBY (1.0 µA with 32-kHz timer active and full SRAM retention), and SHUTDOWN (61 nA with IO wakeup). All modes retain register state except SHUTDOWN, and STANDBY enables 3.2 µs wakeup to full 32 MHz operation - critical for duty-cycled sensor applications.
Is the MSPM0L1304TRHBR pin-compatible with other MSPM0L130x variants?
Yes, the MSPM0L1304TRHBR in the 32-pin VQFN (RHB) package shares identical pinout, electrical characteristics, and peripheral mapping with MSPM0L1303TRHBR, MSPM0L1305TRHBR, and MSPM0L1306TRHBR. This allows hardware reuse across firmware variants - for example, upgrading flash capacity from 16 KB to 64 KB requires only a BOM change, not PCB redesign.
