Texas Instruments MSPM0L1305TRHBR

Overview

MSPM0L1305TRHBR 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, 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 power delivery and smart metering systems.

For engineers reviewing the MSPM0L1305TRHBR datasheet, MSPM0L1305TRHBR pinout, MSPM0L1305TRHBR application, or MSPM0L1305TRHBR 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 analog-peripheral configurability across ADC, OPA, COMP, and DAC.

Technical Context

The MSPM0L1305TRHBR implements an Arm Cortex-M0+ core with on-chip SYSOSC (±1.2% accuracy, 4–32 MHz) and LFOSC (±3%, 32 kHz), eliminating need for external crystals. Its analog subsystem integrates programmable gain (1–32×) into both OPAs and supports configurable internal VREF (1.4 V or 2.5 V).

Digital intelligence includes a 3-channel DMA, four 16-bit timers (8 PWM channels total), event fabric signaling, and communication interfaces with protocol support: UART (LIN/IrDA/DALI/Manchester), I²C (SMBus/PMBus/FM+), and SPI (16 Mbit/s), all operable in STANDBY mode.

FAQ

What is the maximum operating frequency and core architecture of the MSPM0L1305TRHBR?

The MSPM0L1305TRHBR uses an Arm Cortex-M0+ 32-bit RISC core with a maximum operating frequency of 32 MHz. It achieves this speed using the internal SYSOSC oscillator with ±1.2% accuracy across temperature and voltage, eliminating the need for an external crystal while maintaining timing integrity for real-time control loops in the MSPM0L1305TRHBR.

Does the MSPM0L1305TRHBR support debugging during low-power operation?

Yes, the MSPM0L1305TRHBR supports 2-pin Serial Wire Debug (SWD) via PA19/SWDIO and PA20/SWCLK pins, and retains debug accessibility in RUN, STOP, and STANDBY modes. However, debug session suspension is not supported in SHUTDOWN mode, where only IO wakeup is active - ensuring full visibility during development and field validation of the MSPM0L1305TRHBR's low-power behavior.

How many analog inputs does the MSPM0L1305TRHBR ADC support, and what reference options are available?

The MSPM0L1305TRHBR integrates a 12-bit, 1.68-Msps ADC with up to 10 external analog input channels (A0–A9). It supports two programmable internal voltage references: 1.4 V and 2.5 V, selectable via register configuration. These references are routed to VREF+ and VREF− pins (PA23 and PA21), enabling ratiometric measurements and flexible full-scale adjustment in the MSPM0L1305TRHBR's analog front end.

What are the key low-power mode current specifications for the MSPM0L1305TRHBR?

The MSPM0L1305TRHBR offers four defined 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 operation - critical for responsive, energy-efficient designs using the MSPM0L1305TRHBR.

Can the MSPM0L1305TRHBR's operational amplifiers drive ADC inputs directly, and what gain ranges are supported?

Yes, the MSPM0L1305TRHBR's two zero-drift chopper OPAs (OPA0 and OPA1) can directly drive ADC inputs through the configurable analog interconnect matrix. Each OPA includes an integrated programmable gain stage supporting gains from 1× to 32× in discrete steps - enabling direct amplification of µV-level sensor signals (e.g., thermocouples or shunt voltages) before digitization in the MSPM0L1305TRHBR's 12-bit ADC.
