Texas Instruments MSPM0G3506SRHBR

Overview

MSPM0G3506SRHBR from Texas Instruments is a 32-bit Arm® Cortex®-M0+ mixed-signal microcontroller with CAN-FD interface, 64KB flash, 32KB 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, and supports –40°C to 125°C industrial temperature range. It targets real-time motor control and power conversion systems requiring analog precision, deterministic timing, and robust fieldbus communication.

For engineers reviewing the MSPM0G3506SRHBR datasheet, MSPM0G3506SRHBR pinout, MSPM0G3506SRHBR application, or MSPM0G3506SRHBR equivalent, key selection criteria include its 32-pin VQFN package with 28 GPIOs, CAN-FD + UART/I²C/SPI interfaces, ultra-low-power STANDBY mode (1.5µA), and integrated analog signal chain for sensor conditioning and closed-loop actuation.

Technical Context

The MSPM0G3506SRHBR implements an Arm Cortex-M0+ core with MPU and operates at up to 80MHz via internal PLL or external HFXT (4–48MHz). Its analog subsystem includes programmable analog routing between ADCs, OPAs, COMP, DAC, and VREF, enabling flexible signal path configuration 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, and dual window-watchdog timers. The CAN-FD controller supports both CAN 2.0A/B and FD frames up to 5Mbps, with dedicated TX/RX pins and message RAM buffering.

FAQ

What is the maximum operating frequency of the MSPM0G3506SRHBR?

The MSPM0G3506SRHBR operates at up to 80MHz using its internal PLL driven by SYSOSC or external HFXT (4–48MHz). This frequency is fully supported across all operating conditions (–40°C to 125°C, 1.62V–3.6V), enabling deterministic real-time control loops with sub-microsecond interrupt response times. The MSPM0G3506SRHBR's clock system includes fail-safe monitoring and automatic fallback to LFOSC if primary sources fail.

Does the MSPM0G3506SRHBR support CAN-FD in addition to classical CAN?

Yes, the MSPM0G3506SRHBR integrates a full CAN-FD controller compliant with ISO 11898-1:2015, supporting both classical CAN 2.0A/B and CAN-FD frames. It achieves up to 5Mbps data phase rates, includes hardware message RAM with filtering and FIFOs, and provides dedicated CAN_TX/CAN_RX pins (PA26/PA27). The MSPM0G3506SRHBR does not integrate a physical transceiver - an external CAN-FD transceiver is required for bus connection.

How many analog input channels are available on the MSPM0G3506SRHBR in its 32-pin VQFN package?

The MSPM0G3506SRHBR in the 32-pin VQFN (RHB) package provides 11 external analog input channels for ADC0 and ADC1 combined - specifically A0_0 through A0_7 and A1_0 through A1_2. These pins are multiplexed with digital functions but retain full analog performance when configured as ADC inputs. The MSPM0G3506SRHBR's analog mux allows dynamic reconfiguration of these channels to OPAs, COMP, or DAC without GPIO remapping.

What low-power modes are supported by the MSPM0G3506SRHBR, and what is retained in STANDBY mode?

The MSPM0G3506SRHBR supports RUN, SLEEP, STOP, STANDBY, and SHUTDOWN modes. In STANDBY mode, it draws just 1.5µA while retaining 32kHz LFXT operation, RTC with calendar/alarm, full SRAM contents, CPU register state, and peripheral context. Wake-up is possible via CAN-FD activity, GPIO interrupt, or RTC alarm - enabling rapid resumption (<5µs) without full reboot. The MSPM0G3506SRHBR's STANDBY mode is ideal for always-on edge nodes requiring time-stamped events.

Is the MSPM0G3506SRHBR pin-compatible with other members of the MSPM0G350x family in the same package?

Yes, all MSPM0G350x devices (MSPM0G3505/3506/3507) share identical pinouts across each package option - including the 32-pin VQFN (RHB). The MSPM0G3506SRHBR is functionally and physically pin-compatible with MSPM0G3505SRHBR and MSPM0G3507SRHBR, allowing hardware reuse across variants. Differences are limited to flash/SRAM size and factory-programmed constants - no PCB redesign is needed when scaling memory capacity.
