Texas Instruments MSPM0G1105TPTR

Overview

MSPM0G1105TPTR from Texas Instruments is a 32-bit Arm® Cortex®-M0+ microcontroller operating at up to 80MHz, featuring 32KB flash with ECC, 16KB SRAM with parity, dual 12-bit 4Msps ADCs (16-channel), and integrated GPAMP and configurable VREF. It targets motor control, smart metering, and industrial automation where ultra-low-power operation and analog integration are critical.

For engineers reviewing the MSPM0G1105TPTR datasheet, MSPM0G1105TPTR pinout, MSPM0G1105TPTR application, or MSPM0G1105TPTR equivalent, key selection factors include its 48-pin LQFP package, –40°C to 105°C temperature rating, 1.62V–3.6V supply range, STANDBY mode current of 1.5µA, and support for four UARTs (three low-power in STANDBY) and two I²C interfaces.

Technical Context

The MSPM0G1105TPTR implements an Arm Cortex-M0+ core with MPU and executes code from on-chip flash with ECC protection and SRAM with hardware parity. Its clock system integrates SYSOSC (±1.2%), PLL (up to 80MHz), LFOSC (±3%), HFXT, and LFXT, enabling precise timing across operating modes.

Analog subsystem includes two simultaneous-sampling 12-bit ADCs with 16 external channels, 14-bit effective resolution at 250ksps via hardware averaging, one GPAMP, and shared internal VREF (1.4V/2.5V). Digital peripherals comprise 7-channel DMA, two advanced timers with dead-band, five general-purpose timers (including QEI-capable and STANDBY-optimized), RTC, WWDTs, and CRC-32.

FAQ

What is the maximum operating frequency of the MSPM0G1105TPTR?

The MSPM0G1105TPTR operates at up to 80MHz using its Arm Cortex-M0+ core, enabled by the on-chip PLL driven from the internal SYSOSC or external HFXT. This frequency is fully supported across the entire –40°C to 105°C temperature range and 1.62V–3.6V supply voltage window, as verified in TI's production characterization data.

Does the MSPM0G1105TPTR support simultaneous sampling on both ADCs?

Yes, the MSPM0G1105TPTR supports true simultaneous sampling across both 12-bit ADCs, enabling synchronized acquisition of motor phase currents or voltage/current pairs. This capability is hardware-implemented and documented in the ADC section of the SLASF11D datasheet, with timing controlled via shared trigger sources and dedicated result registers.

What low-power modes are available on the MSPM0G1105TPTR, and what is the lowest current draw?

The MSPM0G1105TPTR offers RUN, SLEEP, STOP, STANDBY, and SHUTDOWN modes. The lowest active-retention mode is STANDBY, drawing 1.5µA while retaining SRAM, CPU state, registers, and RTC functionality with 32kHz LFXT running. SHUTDOWN draws 80nA but loses all state except IO configuration and wake-up capability.

Is the MSPM0G1105TPTR pin-compatible with other devices in the MSPM0G110x family?

No-pin compatibility is package-dependent. The MSPM0G1105TPTR uses the 48-pin LQFP (PT) package, which shares pinout with MSPM0G1106TPTR and MSPM0G1107TPTR in the same PT variant. However, it is not pin-compatible with RGZ (VQFN), RHB (VQFN), or DGS (VSSOP) variants due to differing pin counts and signal mappings.

What development tools support the MSPM0G1105TPTR?

The MSPM0G1105TPTR is supported by the LP-MSPM0G3507 LaunchPad™ development kit, MSPM0 Software Development Kit (SDK), Code Composer Studio™ IDE (desktop and cloud), and TI Resource Explorer. Debugging uses standard 2-pin SWD via PA19/PA20, and the SDK includes drivers for all on-chip peripherals including dual ADCs, GPAMP, and STANDBY-optimized timers.
