Texas Instruments MSPM0L1106TRTRR

Overview

MSPM0L1106TRTRR from Texas Instruments is an ultra-low-power 32-bit Arm® Cortex®-M0+ microcontroller operating up to 32 MHz, featuring 64 KB flash, 4 KB SRAM, a 12-bit 1.68-Msps ADC with 6 external analog inputs, integrated GPAMP, and support for –40°C to 105°C operation. It targets battery-powered industrial sensing and power management systems requiring precise analog acquisition and rapid wake-from-standby response.

For engineers reviewing the MSPM0L1106TRTRR datasheet, MSPM0L1106TRTRR pinout, MSPM0L1106TRTRR application, or MSPM0L1106TRTRR equivalent, key selection criteria include its 16-pin WQFN (3 mm × 2 mm) package, 6-channel ADC input capability, 1.0 µA STANDBY current with 32-kHz timer active, and dual UART/I²C/SPI interface support in low-power modes.

Technical Context

The MSPM0L1106TRTRR implements a single-core Arm Cortex-M0+ CPU with on-chip SYSOSC (±1.2% accuracy, 4–32 MHz) and LFOSC (±3%, 32 kHz), eliminating need for external crystals. Its peripheral bus architecture separates ULPCLK (for timers, ADC, GPAMP) and MCLK domains to enable concurrent low-power analog operation and CPU activity.

Power management includes four distinct low-power states: RUN (71 µA/MHz CoreMark), STOP (151 µA @ 4 MHz), STANDBY (1.0 µA with 32-kHz timer + full SRAM retention), and SHUTDOWN (61 nA with IO wakeup). The event fabric and 3-channel DMA offload CPU during sensor acquisition and communication bursts.

FAQ

What is the maximum ADC sampling rate supported by the MSPM0L1106TRTRR?

The MSPM0L1106TRTRR integrates a 12-bit analog-to-digital converter with a maximum sampling rate of 1.68 million samples per second (Msps). This specification is confirmed in the device's official datasheet (SLASEX5C, Section 1 Features and Section 7.12 ADC). The high speed enables precise capture of fast transients in power supply monitoring and motor current sensing applications using the MSPM0L1106TRTRR.

Does the MSPM0L1106TRTRR support external voltage reference for the ADC?

Yes, the MSPM0L1106TRTRR supports external voltage reference input via dedicated pins VREF+ and VREF−. These pins accept an externally supplied reference voltage, which directly sets the ADC's full-scale range. As specified in Section 6.3 Signal Descriptions and Section 7.14 VREF of the datasheet, proper decoupling (capacitor between VREF+ and VREF−) is required. This capability allows the MSPM0L1106TRTRR to maintain ADC accuracy independent of VDD fluctuations.

How many general-purpose I/O pins does the MSPM0L1106TRTRR provide?

The MSPM0L1106TRTRR provides 13 general-purpose I/O pins (PA0 through PA12, excluding NRST and power pins). This count is derived from the 16-pin WQFN (RTR) package configuration detailed in Table 6-1 (Pin Attributes) and Figure 6-6 of the datasheet. Two of these (PA0 and PA1) are 5-V tolerant open-drain, while others support standard-drive or high-speed operation - all configurable via PINCM registers in the MSPM0L1106TRTRR.

What debug interface does the MSPM0L1106TRTRR use, and how many pins are required?

The MSPM0L1106TRTRR uses a 2-pin Serial Wire Debug (SWD) interface, requiring only SWCLK and SWDIO pins (mapped to PA20 and PA19 respectively). This is explicitly stated in Section 1 Features ("2-pin serial wire debug") and confirmed in Figure 6-6 and Table 6-1 of the datasheet. No reset pin is required for debug, reducing PCB routing complexity. The interface is fully supported by TI's Code Composer Studio and third-party tools compatible with ARM SWD protocol for the MSPM0L1106TRTRR.

Is the MSPM0L1106TRTRR qualified for operation at 105°C ambient temperature?

Yes, the MSPM0L1106TRTRR is qualified for continuous operation from –40°C to 105°C ambient temperature, as indicated by the "T" grade in its device nomenclature (Section 5 Device Comparison and Section 7.3 Recommended Operating Conditions). This qualification applies to the full feature set including ADC, GPAMP, and all communication peripherals. The datasheet specifies junction temperature limits up to 125°C, confirming thermal robustness for sealed industrial enclosures where the MSPM0L1106TRTRR is deployed.
