Product details
Overview
MSPM0L1304SRTRR 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 metering and portable medical sensors.
For engineers reviewing the MSPM0L1304SRTRR datasheet, MSPM0L1304SRTRR pinout, MSPM0L1304SRTRR application, or MSPM0L1304SRTRR equivalent, key selection criteria include its 16-pin WQFN (RTR) package, –40°C to 125°C extended temperature rating, 1.62–3.6 V supply range, STANDBY mode consuming only 1.0 µA with full SRAM retention, and dual UART/I²C/SPI interfaces supporting LIN, SMBus, and PMBus protocols.
Technical Context
The MSPM0L1304SRTRR implements a single-core Arm Cortex-M0+ CPU with tightly coupled AHB bus architecture, integrated LDO regulator (VCORE), and hierarchical power domains (PD0/PD1) enabling selective peripheral clock gating. Its analog subsystem includes programmable interconnect between ADC, OPAs, COMP, and DAC - allowing configurable signal chains without external components.
Low-power operation is enforced via four distinct modes: RUN (71 µA/MHz), STOP (44 µA at 32 kHz), STANDBY (1.0 µA with 32-kHz timer active and 3.2 µs wakeup), and SHUTDOWN (61 nA with IO wake capability). The device uses internal SYSOSC (±1.2% accuracy) and LFOSC (±3%) - eliminating need for external crystals in most applications.
Key Specifications

FAQ
What is the maximum operating frequency and process node of the MSPM0L1304SRTRR?
The MSPM0L1304SRTRR operates at a maximum CPU frequency of 32 MHz and is built on Texas Instruments' advanced low-power CMOS process optimized for analog-digital integration. This frequency provides deterministic real-time response for sensor acquisition and control loops while maintaining sub-100 µA/MHz active power efficiency - verified in TI's SLASEX0D datasheet revision January 2024.
Does the MSPM0L1304SRTRR support hardware-based cryptographic acceleration?
No, the MSPM0L1304SRTRR does not include dedicated cryptographic accelerators such as AES or SHA engines. It relies on software libraries for security functions. For applications requiring hardware crypto, consider the MSPM0G3507 or companion secure elements. The MSPM0L1304SRTRR focuses on analog integration and ultra-low-power operation rather than cryptographic throughput.
Can the MSPM0L1304SRTRR's chopper op-amps drive capacitive loads directly?
The MSPM0L1304SRTRR's OPA0 and OPA1 are specified for stable operation with ≤100 pF capacitive loads per TI's SLASEX0D datasheet Section 17. Driving larger capacitive loads (e.g., long PCB traces or display segments) requires external isolation resistors or buffer stages. Always verify stability using the recommended compensation network in the MSPM0L13xx Technical Reference Manual.
What debug interface does the MSPM0L1304SRTRR provide, and what pins are required?
The MSPM0L1304SRTRR provides 2-pin Serial Wire Debug (SWD) using dedicated SWCLK and SWDIO pins - both located on the 16-pin WQFN (RTR) package (pins 12 and 11 respectively). No reset pin is required for debug initialization, and the interface supports full JTAG-like functionality including breakpoints, memory access, and real-time variable watch - confirmed in Section 26 of the SLASEX0D datasheet.
Is the MSPM0L1304SRTRR pin-compatible with other members of the MSPM0L130x family in the same RTR package?
Yes, all MSPM0L130x devices in the 16-pin WQFN (RTR) package - including MSPM0L1303SRTRR, MSPM0L1304SRTRR, MSPM0L1305SRTRR, and MSPM0L1306SRTRR - share identical pinouts, electrical characteristics, and package dimensions. Firmware and hardware designs are interchangeable across these variants, differing only in flash/SRAM capacity and qualification grade (S = 125°C, T = 105°C).
