Texas Instruments MSPM0L1304SDGS28R

Overview

MSPM0L1304SDGS28R 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, and integrated temperature sensing - deployed in battery-powered power delivery and smart metering systems.

For engineers reviewing the MSPM0L1304SDGS28R datasheet, MSPM0L1304SDGS28R pinout, MSPM0L1304SDGS28R application, or MSPM0L1304SDGS28R equivalent, key selection criteria include its 28-pin VSSOP package, –40°C to 125°C extended temperature rating, 1.62–3.6 V supply range, STANDBY mode current of 1.0 µA with 32-kHz timer retention, and analog peripheral configurability across ADC/OPA/COMP/DAC paths.

Technical Context

The MSPM0L1304SDGS28R 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 programmable gain (1–32×) into both OPA0 and OPA1, with dedicated internal connections to the 12-bit ADC and 8-bit reference DAC inside COMP0.

Power management includes five distinct low-power modes: RUN (71 µA/MHz), STOP (151 µA @ 4 MHz), STANDBY (1.0 µA with full SRAM retention and 3.2 µs wakeup), SHUTDOWN (61 nA with GPIO wakeup), and configurable clock domains (MCLK/ULPCLK) enabling selective peripheral gating without CPU intervention.

FAQ

What is the maximum operating frequency of the MSPM0L1304SDGS28R?

The MSPM0L1304SDGS28R features an Arm Cortex-M0+ core rated for up to 32 MHz operation. This frequency is supported across the full –40°C to 125°C temperature range and 1.62–3.6 V supply voltage window, with internal SYSOSC accuracy of ±1.2% - eliminating need for external crystal in timing-critical but cost-sensitive applications like power supply supervisors.

Does the MSPM0L1304SDGS28R support hardware debugging?

Yes, the MSPM0L1304SDGS28R supports 2-pin serial wire debug (SWD) via dedicated PA20 (SWCLK) and PA19 (SWDIO) pins. These pins are multiplexed with ADC inputs and communication peripherals but retain debug functionality regardless of peripheral configuration - enabling in-circuit programming and real-time trace without requiring additional debug headers.

How many analog-to-digital converter channels does the MSPM0L1304SDGS28R provide?

The MSPM0L1304SDGS28R integrates a single 12-bit ADC with up to 10 external analog input channels (A0–A9). All channels are accessible on the 28-pin VSSOP package, with A0–A5 mapped to dedicated pins and A6–A9 shared with debug and communication functions - allowing flexible routing for mixed-signal applications such as multi-rail power monitoring.

What low-power modes are available on the MSPM0L1304SDGS28R?

The MSPM0L1304SDGS28R offers four defined low-power states: RUN (71 µA/MHz), STOP (151 µA @ 4 MHz), STANDBY (1.0 µA with full SRAM retention and 32-kHz timer active), and SHUTDOWN (61 nA with GPIO wakeup). STANDBY mode enables fastest wakeup (3.2 µs) while preserving all register contents - ideal for interrupt-driven sensor polling in battery-powered nodes.

Can the MSPM0L1304SDGS28R drive 5-V logic interfaces directly?

Yes, the MSPM0L1304SDGS28R includes two 5-V-tolerant open-drain I/O pins (PA0 and PA1) with fail-safe protection. These pins tolerate 5-V signals while operating from a 1.62–3.6 V supply, enabling direct connection to legacy I2C buses, SMBus peripherals, or 5-V level-shifted UART lines without external translators - simplifying interoperability in mixed-voltage industrial systems.
