Texas Instruments MSPM0G1105TRGZR

Overview

MSPM0G1105TRGZR from Texas Instruments is a 32-bit Arm® Cortex®-M0+ microcontroller with 32KB flash, 16KB SRAM, dual 12-bit 4Msps ADCs (16 external channels), 1.62V–3.6V operation, and –40°C to 105°C temperature rating-designed for motor control, smart metering, and industrial power conversion systems.

For engineers reviewing the MSPM0G1105TRGZR datasheet, MSPM0G1105TRGZR pinout, MSPM0G1105TRGZR application, or MSPM0G1105TRGZR equivalent, key selection criteria include its 48-pin VQFN package, integrated GPAMP and configurable VREF, ultra-low-power STANDBY mode (1.5µA), and support for four UARTs-including one with LIN/IrDA/DALI/Smart Card compatibility.

Technical Context

The MSPM0G1105TRGZR implements an Arm Cortex-M0+ core with MPU, operates up to 80MHz via PLL or internal SYSOSC (±1.2% accuracy), and integrates dual simultaneous-sampling ADCs with hardware averaging enabling 14-bit effective resolution at 250ksps. Its clock system supports HFXT (4–48MHz), LFXT (32kHz), and internal oscillators.

Power management includes five low-power modes: RUN (101µA/MHz), SLEEP (40µA/MHz), STOP (190µA @ 4MHz), STANDBY (1.5µA with RTC/SRAM retention), and SHUTDOWN (80nA with IO wake-up). The device features 7-channel DMA, two advanced timers with dead-band and fault handling, and CRC-16/32 for data integrity.

FAQ

What is the maximum operating frequency of the MSPM0G1105TRGZR?

The MSPM0G1105TRGZR operates at up to 80MHz using its integrated PLL or internal SYSOSC. This frequency is sustained across the full –40°C to 105°C temperature range and 1.62V–3.6V supply voltage, enabling deterministic real-time control loop execution in demanding industrial environments. The MSPM0G1105TRGZR achieves this performance while maintaining sub-100µA/MHz active power consumption.

Does the MSPM0G1105TRGZR support hardware-accelerated cryptography?

The MSPM0G1105TRGZR includes a dedicated cyclic redundancy checker (CRC-16 and CRC-32) engine for fast checksum computation, but does not integrate AES, SHA, or other cryptographic accelerators. It supports secure boot via ROM-based bootloader (BSL) with I²C/UART interfaces, and firmware integrity verification relies on CRC-based validation. For advanced encryption, external co-processors or software libraries are required. The MSPM0G1105TRGZR prioritizes deterministic timing and analog integration over cryptographic throughput.

How many analog input channels does the MSPM0G1105TRGZR support?

The MSPM0G1105TRGZR supports up to 16 external analog input channels across its two 12-bit, 4Msps ADCs (ADC0 and ADC1). Pin assignments vary by package: in the 48-pin VQFN (RGZ), channels A0_0 through A0_12 and A1_0 through A1_6 are available, totaling 16 distinct inputs. All channels support simultaneous sampling, and hardware averaging enables 14-bit effective resolution at 250ksps-critical for precision metrology and motor current sensing in the MSPM0G1105TRGZR.

What debug interface does the MSPM0G1105TRGZR provide?

The MSPM0G1105TRGZR provides a 2-pin Serial Wire Debug (SWD) interface using PA19 (SWDIO) and PA20 (SWCLK). This interface supports full JTAG-equivalent functionality-including flash programming, real-time register inspection, breakpoint setting, and memory read/write-without requiring additional pins beyond the standard SWD pair. The MSPM0G1105TRGZR does not include JTAG TDI/TDO/TMS pins, simplifying layout while retaining full development visibility.

Is the MSPM0G1105TRGZR pin-compatible with other devices in the MSPM0G110x family?

Within the same package variant, the MSPM0G1105TRGZR is pin-compatible with MSPM0G1106TRGZR and MSPM0G1107TRGZR-sharing identical 48-pin VQFN (RGZ) pinout, power domains, and peripheral mappings. This allows direct substitution for memory scaling without PCB redesign. However, it is not pin-compatible with other packages (e.g., LQFP or VSSOP), and functional differences-such as flash size, SRAM, or ADC channel count-must be validated in firmware. The MSPM0G1105TRGZR's compatibility is strictly limited to RGZ-package variants in the same family.
