Product details
Overview
MSPM0G3505SRHBR from Texas Instruments is a 32-bit Arm® Cortex®-M0+ microcontroller with CAN-FD interface, 32KB flash, 16KB SRAM, and operation up to 80MHz. It integrates dual 12-bit 4Msps ADCs (11 external channels), one 12-bit 1Msps DAC, two zero-drift chopper op-amps, three high-speed comparators, and supports –40°C to 125°C industrial temperature range. It targets motor control and smart metering applications requiring robust analog integration and real-time communication.
For engineers reviewing the MSPM0G3505SRHBR datasheet, MSPM0G3505SRHBR pinout, MSPM0G3505SRHBR application, or MSPM0G3505SRHBR equivalent, this page delivers verified specifications, package-specific I/O mapping, low-power mode behavior, CAN-FD timing compliance, and direct alternative part comparisons - all grounded in TI's SLASEX6C production data sheet (October 2025 revision).
Technical Context
The MSPM0G3505SRHBR implements an Arm Cortex-M0+ core with MPU and operates at up to 80MHz via internal PLL fed by SYSOSC or external HFXT (4–48MHz). Its analog subsystem features programmable interconnect between ADCs, OPAs, COMP, DAC, and VREF, enabling sensor signal conditioning without external components.
Digital peripherals include a 7-channel DMA, math accelerator (DIV/SQRT/MAC/TRIG), five timers (including two 16-bit advanced timers with deadband), RTC with calendar, two WWDTs, and four UARTs - three of which retain functionality in STANDBY mode (1.5µA). The CAN-FD controller supports both CAN 2.0A/B and FD frames with bit rates up to 5Mbps.

FAQ
What is the maximum operating frequency and core architecture of the MSPM0G3505SRHBR?
The MSPM0G3505SRHBR features an Arm Cortex-M0+ CPU core with a maximum operating frequency of 80MHz, achieved via its integrated PLL. This frequency is supported across the full –40°C to +125°C temperature range and 1.62V–3.6V supply voltage window. The core includes a memory protection unit (MPU) for secure partitioning of code and data spaces, essential for functional safety compliance in industrial applications. All timing specifications in the SLASEX6C datasheet are validated at this 80MHz rate.
How many analog input channels does the MSPM0G3505SRHBR support, and what is their resolution and sampling rate?
The MSPM0G3505SRHBR integrates two simultaneous-sampling 12-bit analog-to-digital converters (ADCs) supporting up to 11 external analog input channels in the 32-pin VQFN package. Each ADC achieves 4Msps sampling rate, and hardware averaging enables 14-bit effective resolution at 250ksps. This performance is confirmed in Table 5-1 and Section 7.12 of the SLASEX6C datasheet, making it suitable for high-fidelity current/voltage sensing in motor control and power conversion.
Does the MSPM0G3505SRHBR support CAN-FD, and what are its key CAN timing capabilities?
Yes, the MSPM0G3505SRHBR includes a fully compliant CAN-FD controller supporting ISO 11898-1:2015. It enables data rates up to 5Mbps in FD mode and payloads up to 64 bytes per frame. The controller operates in both CAN 2.0A/B and FD modes, with flexible bit timing configuration and built-in error handling. These capabilities are documented in Section 28 of the Technical Reference Manual and validated in TI's CAN-FD conformance test reports for the MSPM0G350x family.
What low-power modes are available on the MSPM0G3505SRHBR, and what is the lowest achievable current draw?
The MSPM0G3505SRHBR supports RUN, SLEEP, STOP, STANDBY, and SHUTDOWN modes. The lowest active-retention mode is STANDBY at 1.5µA (with 32kHz LFXT, RTC, SRAM, and CPU state retained), and the absolute minimum is SHUTDOWN at 80nA with IO wake-up capability. These values are measured per Section 7.5 of SLASEX6C and reflect actual silicon characterization - not typical estimates - ensuring predictable battery life in always-on industrial sensors.
What development tools and software support are available for the MSPM0G3505SRHBR?
Texas Instruments provides full support for the MSPM0G3505SRHBR via the free MSPM0 Software Development Kit (SDK), integrated into Code Composer Studio™ IDE (desktop and cloud). Hardware support includes the LP-MSPM0G3507 LaunchPad™ development kit - compatible with MSPM0G3505SRHBR via pin-compatible headers - and the MSPM0G350x EVM.
