It integrates dual 12-bit 4Msps ADCs, 12-bit 1Msps DAC, two zero-drift chopper op-amps, three high-speed comparators, and supports –40°C to 125°C industrial temperature range. Used in motor control systems requiring real-time analog sensing, CAN-FD communication, and ultra-low-power standby.

For engineers reviewing the MSPM0G3507SDGS28R datasheet, MSPM0G3507SDGS28R pinout, MSPM0G3507SDGS28R application, or MSPM0G3507SDGS28R equivalent, this page delivers verified technical context, package-specific pin functions, low-power mode trade-offs, CAN-FD timing compliance, and validated alternative options for industrial embedded design.

Technical Context

The MSPM0G3507SDGS28R implements an Arm Cortex-M0+ core with MPU, paired with a dual-ADC subsystem supporting simultaneous sampling across 11 external channels (VSSOP-28 package constraint), hardware averaging enabling 14-bit effective resolution at 250ksps, and programmable analog interconnect between ADC, OPA, COMP, DAC, and VREF.

Its clock system combines internal SYSOSC (±1.2% accuracy), PLL (up to 80MHz), LFXT/LFOSC, and HFXT sources; 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)-all validated for the 28-pin VSSOP variant.

FAQ

What is the maximum operating frequency and core architecture of the MSPM0G3507SDGS28R?

The MSPM0G3507SDGS28R features an Arm Cortex-M0+ core with a maximum operating frequency of 80MHz. It includes a memory protection unit (MPU) for secure task isolation and operates across –40°C to 125°C. This frequency is achieved using the internal PLL driven by SYSOSC or external HFXT, and is fully supported in the 28-pin VSSOP package per TI's SLASEX6C datasheet revision October 2025.

Does the MSPM0G3507SDGS28R support CAN-FD, and what are its physical layer requirements?

Yes, the MSPM0G3507SDGS28R integrates a CAN-FD controller compliant with ISO 11898-1:2015 and supports data rates up to 5Mbps. It requires an external CAN transceiver (e.g., TCAN1042) connected to PA26 (CAN_TX) and PA27 (CAN_RX). The device does not include integrated PHY; signal integrity depends on proper termination, stub length control, and transceiver selection per ISO 11898-2:2016.

How many analog input channels are accessible on the MSPM0G3507SDGS28R in the 28-pin VSSOP package?

The MSPM0G3507SDGS28R supports up to 11 external analog input channels in the 28-pin VSSOP package. These are mapped across A0_0 to A0_7 and A1_0 to A1_3 (PA27–PA21, PA18–PA15, PA14), with dual 12-bit ADCs capable of simultaneous sampling. Channel count is reduced from the 17-channel capability of larger packages due to pin limitations-not a functional restriction of the silicon.

What low-power modes are available on the MSPM0G3507SDGS28R, and what is the lowest achievable current draw?

The MSPM0G3507SDGS28R supports five low-power modes: RUN, SLEEP, STOP, STANDBY, and SHUTDOWN. The lowest current draw is 80nA in SHUTDOWN mode with IO retention and wake-up capability. STANDBY mode draws 1.5µA while retaining RTC, SRAM, CPU state, and registers-validated for the VSSOP package under specified conditions in the SLASEX6C datasheet.

Is the MSPM0G3507SDGS28R pin-compatible with other members of the MSPM0G350x family in the same package?

Yes, the MSPM0G3507SDGS28R is pin-compatible with MSPM0G3505SDGS28R and MSPM0G3506SDGS28R in the 28-pin VSSOP package. All share identical pinout, electrical characteristics, and peripheral mapping. Firmware portability is ensured across flash variants (32KB/64KB/128KB), though users must verify memory layout and linker script alignment for each part.
