Product details
Overview
MSPM0L1105TRTRR 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, and integrated GPAMP and temperature sensor. It targets battery-powered industrial sensing and power management systems requiring extended temperature operation (–40°C to 105°C) and sub-µA standby current.
For engineers reviewing the MSPM0L1105TRTRR datasheet, MSPM0L1105TRTRR pinout, MSPM0L1105TRTRR application, or MSPM0L1105TRTRR equivalent, key selection criteria include its 16-pin WQFN (3 mm × 2 mm) package, dual UART support with LIN/IrDA/DALI, 1.62–3.6 V supply range, and STANDBY mode consuming only 1.0 µA with full SRAM retention and 32-kHz timer active.
Technical Context
The MSPM0L1105TRTRR implements a single-core Arm Cortex-M0+ CPU with on-chip SYSOSC (±1.2% accuracy, 4–32 MHz) and LFOSC (±3%, 32 kHz), eliminating external crystals. Its peripheral bus architecture separates high-speed (MCLK) and ultra-low-power (ULPCLK) domains to enable concurrent operation of timers, ADC, and communication interfaces in low-power modes.
It integrates a 3-channel DMA controller, event fabric for cross-peripheral triggering, four 16-bit general-purpose timers supporting 8 PWM outputs, and intelligent digital peripherals including windowed watchdog and CRC-16/32 accelerators - all accessible without CPU intervention in STANDBY mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSPM0L1106TRTRR | 64 KB flash (vs. 32 KB), same package, identical peripherals and pinout | Supports larger firmware images with bootloader, OTA updates, or complex protocol stacks (e.g., Matter over Thread) | Select when future firmware expansion or dual-bank secure boot is required - drop-in replacement with no layout change. |
| STM32G031F8P6 | Arm Cortex-M0+, 64 MHz, 64 KB flash, 8 KB SRAM, but no integrated GPAMP or configurable VREF | Lacks analog signal conditioning capability; requires external op-amp and reference for precision sensor front-end | Choose for higher clock speed and memory where analog integration is handled externally - not pin-compatible; different 20-pin TSSOP footprint. |
Compared with MSPM0L1106TRTRR, the MSPM0L1105TRTRR trades flash capacity for lower unit cost in fixed-function applications; versus STM32G031F8P6, it delivers superior analog integration in a smaller package but at lower maximum frequency - making it optimal for space- and power-constrained sensing nodes.

FAQ
What is the maximum operating frequency of the MSPM0L1105TRTRR?
The MSPM0L1105TRTRR operates at up to 32 MHz using its internal SYSOSC with ±1.2% accuracy - sufficient for real-time control loops and high-speed communication without external crystal. This frequency is supported across the full –40°C to 105°C temperature range and 1.62–3.6 V supply, with zero wait states below 24 MHz and one wait state at 32 MHz per the Technical Reference Manual.
Does the MSPM0L1105TRTRR support hardware debugging?
Yes, the MSPM0L1105TRTRR supports 2-pin Serial Wire Debug (SWD) via dedicated SWCLK and SWDIO pins. This enables full JTAG-style programming, breakpoint setting, register inspection, and real-time variable monitoring using TI's Code Composer Studio or third-party IDEs with SWD support - all without occupying additional GPIOs or requiring a separate debug header.
How many analog input channels does the MSPM0L1105TRTRR ADC support?
The MSPM0L1105TRTRR integrates a single 12-bit ADC supporting up to 10 external analog input channels (A0–A9). In the 16-pin RTR package, pins A0–A6 are physically available; A7–A9 are not routed out. The ADC achieves 1.68 million samples per second with configurable 1.4-V or 2.5-V internal reference voltage - enabling high-fidelity sensor data acquisition in compact designs.
Can the MSPM0L1105TRTRR operate from a single-cell lithium battery?
Yes, the MSPM0L1105TRTRR operates from 1.62 V to 3.6 V - fully compatible with discharge profiles of single-cell Li-ion (3.0–4.2 V) and LiFePO₄ (2.5–3.65 V) batteries. Its RUN-mode current of 71 µA/MHz and SHUTDOWN current of 61 nA allow multi-year operation in battery-gauging or periodic wake-up sensor applications without external regulators.
What communication interfaces are available on the MSPM0L1105TRTRR?
The MSPM0L1105TRTRR provides two UARTs (supporting LIN, IrDA, DALI, Manchester), one I²C interface (FM+, 1 Mbit/s), and one SPI (16 Mbit/s). Both UARTs retain functionality in STANDBY mode for wake-on-frame, and I²C supports SMBus/PMBus protocols - making it suitable for smart sensors, lighting controllers, and industrial monitors requiring multiple standardized serial links.
