Texas Instruments MSPM0G3505SDGS28R

Overview

MSPM0G3505SDGS28R from Texas Instruments is a 32-bit Arm® Cortex®-M0+ microcontroller with CAN-FD interface, 32KB flash, 16KB SRAM, and 24 GPIOs in a 28-pin VSSOP package. It operates from 1.62V to 3.6V across –40°C to 125°C, integrates dual 12-bit 4-Msps ADCs, one 12-bit DAC, two zero-drift op-amps, and supports ultra-low-power STANDBY mode (1.5µA). It targets motor control and industrial power conversion where compact size, CAN-FD connectivity, and analog integration are critical.

For engineers reviewing the MSPM0G3505SDGS28R datasheet, MSPM0G3505SDGS28R pinout, MSPM0G3505SDGS28R application, or MSPM0G3505SDGS28R equivalent, this page delivers verified specifications, package-specific pin functions, real-world use cases in motor drives and smart metering, and validated alternative options for design flexibility and supply continuity.

Technical Context

The MSPM0G3505SDGS28R implements an Arm Cortex-M0+ core at up to 80MHz with MPU, integrated 7-channel DMA, math accelerator (DIV/SQRT/MAC/TRIG), and dual 16-bit advanced timers with deadband support. Its analog subsystem includes programmable analog routing between ADCs, OPAs, COMP, DAC, and VREF, enabling sensor signal conditioning and closed-loop control without external components.

It features a dual-bus architecture: AHB for CPU/DMA access to flash/SRAM/peripherals, and ULPCLK domain for low-power peripherals (UART/I²C/SPI/CAN/RTC) active in STANDBY. Clock sources include internal SYSOSC (±1.2%), PLL, HFXT/LFXT, and LFOSC (±3%), supporting precise timing for CAN-FD bit-rate accuracy and RTC calendar operation.

FAQ

What is the maximum operating frequency and core type of the MSPM0G3505SDGS28R?

The MSPM0G3505SDGS28R features an Arm Cortex-M0+ core with a maximum operating frequency of 80MHz. This clock speed is achieved using the on-chip PLL fed by internal SYSOSC or external HFXT. The core includes a memory protection unit (MPU) and supports Thumb-2 instruction set for efficient code density and real-time determinism in motor control loops.

Does the MSPM0G3505SDGS28R support CAN-FD, and what are its bit-rate capabilities?

Yes, the MSPM0G3505SDGS28R includes a fully compliant CAN-FD controller supporting both Classical CAN (up to 1Mbps) and CAN-FD (up to 5Mbps data phase). It implements ISO 11898-1:2015, includes programmable bit timing, automatic retransmission, and hardware CRC-16/32 - enabling robust communication in electric drive and industrial automation networks.

How many analog-to-digital converter (ADC) channels does the MSPM0G3505SDGS28R provide, and what is their resolution and speed?

The MSPM0G3505SDGS28R integrates two independent 12-bit ADCs, each capable of 4Msps sampling. In the 28-pin VSSOP variant, 11 external analog input channels are available (A0_0 through A0_12, excluding A0_11). Hardware averaging enables 14-bit effective resolution at 250ksps, supporting high-accuracy current and voltage sensing in motor drives.

What low-power modes are available on the MSPM0G3505SDGS28R, and what is the lowest current consumption?

The MSPM0G3505SDGS28R offers RUN, SLEEP, STOP, STANDBY, and SHUTDOWN modes. The lowest active-retention mode is STANDBY at 1.5µA (with 32kHz LFXT, RTC, SRAM, CPU state, and registers retained). SHUTDOWN draws just 80nA while retaining IO state and wake-up capability - ideal for battery-backed systems requiring multi-year shelf life.

Is the MSPM0G3505SDGS28R pin-compatible with other members of the MSPM0G350x family?

No - the MSPM0G3505SDGS28R uses a 28-pin VSSOP package with 24 GPIOs, while other variants (e.g., MSPM0G3505SPMR in 64-pin LQFP) have different pin counts, layouts, and signal allocations. Pin compatibility exists only within identical package types (e.g., all 28-pin VSSOP variants share the same pinout), but not across package families.
