Texas Instruments MSPM0G1106TRHBR

Overview

MSPM0G1106TRHBR from Texas Instruments is a 32-bit Arm® Cortex®-M0+ microcontroller with 64KB flash, 32KB SRAM, dual 12-bit 4Msps ADCs (11 external channels), 1.62V–3.6V operation, and –40°C to 105°C extended temperature range-designed for motor control and industrial power conversion where analog integration, low-power standby (1.5µA), and compact 32-pin VQFN packaging are critical.

For engineers reviewing the MSPM0G1106TRHBR datasheet, MSPM0G1106TRHBR pinout, MSPM0G1106TRHBR application, or MSPM0G1106TRHBR equivalent, key selection considerations include its 32-pin VQFN (5mm × 5mm) footprint, 28 GPIO count, dual ADC channel count (11 external), GPAMP support, and STANDBY-mode timer retention-essential for battery-backed or thermally constrained embedded systems.

Technical Context

The MSPM0G1106TRHBR implements an Arm Cortex-M0+ core at up to 80MHz with MPU, integrated SYSOSC (±1.2% accuracy), PLL, and dual clock domains (MCLK/ULPCLK) enabling concurrent high-speed and ultra-low-power peripheral operation. Its memory subsystem includes ECC-protected flash and parity-secured SRAM.

Analog subsystem features two simultaneous-sampling 12-bit ADCs with hardware averaging (14-bit effective at 250ksps), configurable 1.4V/2.5V shared VREF, one GPAMP, and integrated temperature sensor-all accessible via dedicated analog I/O pins mapped to the 32-pin VQFN package.

FAQ

What is the maximum operating frequency of the MSPM0G1106TRHBR?

The MSPM0G1106TRHBR operates at up to 80MHz using its Arm Cortex-M0+ core, enabled by the integrated PLL and high-accuracy SYSOSC (±1.2%). This frequency is fully supported across the –40°C to 105°C temperature range and 1.62V–3.6V supply, making it suitable for real-time motor control loops with sub-microsecond interrupt latency. The MSPM0G1106TRHBR maintains timing compliance without derating under worst-case thermal and voltage conditions.

Does the MSPM0G1106TRHBR support hardware error correction for flash and SRAM?

Yes, the MSPM0G1106TRHBR includes built-in error correction code (ECC) for its 64KB flash memory and hardware parity checking for its 32KB SRAM. These features detect and correct single-bit errors in real time, preventing silent data corruption in mission-critical applications such as industrial power conversion or medical device control. The MSPM0G1106TRHBR implements these protections without software overhead or performance penalty.

How many analog input channels does the MSPM0G1106TRHBR support?

The MSPM0G1106TRHBR supports 11 external analog input channels across its dual 12-bit, 4Msps ADCs. This count is specific to the 32-pin VQFN (RHB) package variant, as confirmed in Table 5-1 of the device datasheet. The MSPM0G1106TRHBR also includes internal channels for temperature sensor and VREF monitoring, but only 11 pins are assigned to external analog signals in this package configuration.

What debug interface does the MSPM0G1106TRHBR provide?

The MSPM0G1106TRHBR provides a 2-pin Serial Wire Debug (SWD) interface via PA19 (SWDIO) and PA20 (SWCLK), supporting full JTAG-equivalent functionality including breakpoints, register inspection, and flash programming. This interface operates independently of the main application code and remains active in all debug-enabled modes-including RUN, SLEEP, and STOP-enabling non-intrusive validation of real-time control behavior. The MSPM0G1106TRHBR requires no additional debug hardware beyond a standard SWD probe.

Is the MSPM0G1106TRHBR pin-compatible with other MSPM0G110x variants in the same package?

Yes, the MSPM0G1106TRHBR shares identical pinout, electrical characteristics, and peripheral mapping with other RHB-package MSPM0G110x devices-including MSPM0G1107TRHBR and MSPM0G1105TRHBR-making them drop-in replacements within the same footprint. All RHB variants use the same 32-pin VQFN layout, signal naming, and I/O structure, allowing firmware reuse and simplified BOM management across flash-size variants. The MSPM0G1106TRHBR requires no PCB changes when substituted for these compatible parts.
