Texas Instruments MSPM0G3505SRGZR

Overview

MSPM0G3505SRGZR from Texas Instruments is a 32-bit Arm® Cortex®-M0+ microcontroller with CAN-FD interface, 32KB flash, 16KB SRAM, dual 12-bit 4Msps ADCs (16 external channels), and operation from –40°C to 125°C at 1.62V–3.6V supply. It targets motor control, industrial inverters, and smart metering where integrated analog precision, real-time CAN-FD communication, and ultra-low-power STANDBY mode (1.5µA) are critical.

For engineers reviewing the MSPM0G3505SRGZR datasheet, MSPM0G3505SRGZR pinout, MSPM0G3505SRGZR application, or MSPM0G3505SRGZR equivalent, key selection factors include its 48-pin VQFN (7mm × 7mm) package, CAN-FD + dual high-speed ADC support, 1.5µA STANDBY current with RTC/SRAM retention, and compatibility with TI's MSPM0 SDK and LP-MSPM0G3507 LaunchPad™.

Technical Context

The MSPM0G3505SRGZR implements an Arm Cortex-M0+ core with MPU, running up to 80MHz via PLL or internal SYSOSC (±1.2% accuracy). Its analog subsystem integrates two simultaneous-sampling ADCs with hardware averaging (14-bit effective at 250ksps), three comparators each with 8-bit reference DACs, two zero-drift chopper op-amps (0.5µV/°C drift), and a programmable gain stage (up to 32×).

Digital intelligence includes a 7-channel DMA, math accelerator (DIV/SQRT/MAC/TRIG), five timers (including two 16-bit advanced timers with deadband), and dual-window watchdogs. The CAN-FD peripheral supports both CAN 2.0A/B and FD frames up to 5Mbps, with dedicated TX/RX pins and message RAM for flexible filtering and buffering.

FAQ

What is the maximum operating frequency of the MSPM0G3505SRGZR?

The MSPM0G3505SRGZR features an Arm Cortex-M0+ core with a maximum operating frequency of 80MHz, achieved using the on-chip PLL driven by the internal 4–32MHz SYSOSC or external HFXT crystal. This frequency is fully supported across the full –40°C to 125°C temperature range and 1.62V–3.6V supply voltage window, enabling deterministic real-time execution for motor control and power conversion applications.

Does the MSPM0G3505SRGZR support CAN-FD in addition to classic CAN 2.0?

Yes, the MSPM0G3505SRGZR integrates a fully compliant CAN-FD controller supporting ISO 11898-1:2015. It operates in both CAN 2.0A/B modes and CAN-FD mode with bit rates up to 5Mbps in the data phase. The peripheral includes message RAM, flexible filtering, and automatic retransmission - all accessible via TI's driverlib and HAL APIs in the MSPM0 SDK.

How many analog input channels does the MSPM0G3505SRGZR support, and what is their sampling capability?

The MSPM0G3505SRGZR integrates two independent 12-bit analog-to-digital converters (ADC0 and ADC1), each capable of 4Msps sampling. It supports up to 16 external analog input channels (A0_0–A0_7 and A1_0–A1_7), with simultaneous sampling enabled via hardware synchronization. At 250ksps, hardware averaging achieves 14-bit effective resolution - ideal for high-fidelity current/voltage sensing in motor drives.

What low-power modes are available on the MSPM0G3505SRGZR, and what is the lowest current consumption?

The MSPM0G3505SRGZR offers five low-power modes: RUN, SLEEP, STOP, STANDBY, and SHUTDOWN. The lowest active mode is STANDBY, consuming just 1.5µA while retaining RTC operation, 32KB SRAM, CPU register state, and wake-up capability via CAN, GPIO, or timer events. SHUTDOWN draws only 80nA but retains only IO state and wake-up capability - no SRAM or RTC retention.

Is the MSPM0G3505SRGZR pin-compatible with other members of the MSPM0G350x family?

Yes, the MSPM0G3505SRGZR in the 48-pin VQFN (RGZ) package shares identical pinout and electrical characteristics with the MSPM0G3506SRGZR and MSPM0G3507SRGZR - all three devices are pin-for-pin compatible. This allows seamless migration between memory variants (32KB/64KB/128KB flash) without PCB redesign, provided the target firmware fits within the selected device's memory constraints.
