Texas Instruments MSPM0L1306SRTRR

Overview

MSPM0L1306SRTRR from Texas Instruments is an ultra-low-power 32-bit Arm® Cortex®-M0+ microcontroller operating up to 32 MHz, with 64 KB flash, 4 KB SRAM, and integrated analog peripherals including a 12-bit 1.68-Msps ADC, two zero-drift chopper op-amps, and a high-speed comparator-designed for battery-powered industrial sensing and power management applications.

For engineers reviewing the MSPM0L1306SRTRR datasheet, MSPM0L1306SRTRR pinout, MSPM0L1306SRTRR application, or MSPM0L1306SRTRR equivalent, key selection criteria include its 16-pin WQFN (3 mm × 2 mm) 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 support for LIN, DALI, and Smart Card protocols via dual UARTs.

Technical Context

The MSPM0L1306SRTRR implements a single-core Arm Cortex-M0+ CPU with on-chip SYSOSC (±1.2% accuracy) eliminating external crystals, and integrates a programmable analog subsystem enabling direct signal conditioning-ADC inputs can be routed through OPA0/OPA1 gain stages (1×–32×) or COMP0 with built-in 8-bit DAC before digitization.

Its low-power architecture supports five operational 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), SHUTDOWN (61 nA with IO wakeup), and deep-sleep wake sources include GPIO, comparator output, and timer events-all accessible in the 16-pin WQFN footprint.

FAQ

What is the maximum operating frequency of the MSPM0L1306SRTRR?

The MSPM0L1306SRTRR features an Arm Cortex-M0+ CPU with a maximum operating frequency of 32 MHz. This is achieved using the internal SYSOSC, which maintains ±1.2% accuracy across voltage and temperature without requiring an external crystal. The 32 MHz clock supports real-time control tasks such as motor commutation timing and high-speed ADC sampling at 1.68 Msps.

Does the MSPM0L1306SRTRR support hardware debugging?

Yes, the MSPM0L1306SRTRR supports 2-pin Serial Wire Debug (SWD) via dedicated SWCLK and SWDIO pins. This interface enables full programming, real-time debugging, and trace capabilities using standard tools like Code Composer Studio™ and TI's MSP Software Development Kit. No external debug probe is required beyond a compatible SWD adapter.

How many analog input channels does the MSPM0L1306SRTRR ADC support?

The MSPM0L1306SRTRR integrates a 12-bit ADC supporting up to 6 external analog input channels (A0–A5) in its 16-pin WQFN package. These inputs are mapped to physical pins PA27 through PA22 and support programmable internal voltage references (1.4 V or 2.5 V), enabling precise ratiometric measurements in sensor applications without external reference ICs.

What low-power modes are available on the MSPM0L1306SRTRR?

The MSPM0L1306SRTRR offers four configurable low-power modes: RUN (71 µA/MHz), STOP (44 µA at 32 kHz), STANDBY (1.0 µA with 32-kHz timer active and full SRAM retention), and SHUTDOWN (61 nA with GPIO wakeup). All modes retain register state except SHUTDOWN, and wakeup latency from STANDBY is 3.2 µs-critical for responsive event-driven sensing.

Can the MSPM0L1306SRTRR drive 5-V logic directly?

Yes, the MSPM0L1306SRTRR 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 interface with legacy 5-V peripherals such as I²C EEPROMs or optocouplers without level-shifting circuitry-reducing BOM count and PCB area.
