Texas Instruments MSPM0G1505SRHBR

Overview

MSPM0G1505SRHBR from Texas Instruments is a 32-bit Arm® Cortex®-M0+ microcontroller operating at up to 80MHz, featuring 32KB flash with ECC, 16KB SRAM with hardware parity, and dual 12-bit 4Msps ADCs with 17-channel analog input capability - deployed in motor control, industrial power conversion, and smart metering systems.

For engineers reviewing the MSPM0G1505SRHBR datasheet, MSPM0G1505SRHBR pinout, MSPM0G1505SRHBR application, or MSPM0G1505SRHBR equivalent, key selection criteria include its 32-pin VQFN (5mm × 5mm) package, –40°C to 125°C extended temperature rating, 1.62V–3.6V supply range, integrated zero-drift op-amps, and STANDBY mode current of 1.5µA with RTC and SRAM retention.

Technical Context

The MSPM0G1505SRHBR implements a memory protection unit (MPU), 7-channel DMA, and math accelerator supporting DIV/SQRT/MAC/TRIG operations. Its analog subsystem integrates two simultaneous-sampling ADCs, three high-speed comparators (32ns propagation delay), two zero-drift chopper op-amps (0.5µV/°C drift), and configurable analog routing between ADC, OPA, GPAMP, COMP, and DAC.

Digital peripherals include two 16-bit advanced timers with deadband and complementary outputs (up to 12 PWM channels), five general-purpose timers (including QEI support and STANDBY-capable variants), two window-watchdog timers, and RTC with calendar/alarm. Clocking supports internal SYSOSC (±1.2%), PLL (up to 80MHz), HFXT (4–48MHz), and LFXT (32kHz).

FAQ

What is the maximum operating frequency of the MSPM0G1505SRHBR?

The MSPM0G1505SRHBR operates at up to 80MHz using its integrated PLL, which locks to internal SYSOSC or external HFXT sources. This frequency is fully supported across the full –40°C to 125°C temperature range and 1.62V–3.6V supply voltage, enabling deterministic real-time control loops in demanding industrial applications. The MSPM0G1505SRHBR maintains timing compliance without derating under worst-case conditions.

Does the MSPM0G1505SRHBR support hardware CRC and encryption?

Yes, the MSPM0G1505SRHBR includes dedicated peripherals for cyclic redundancy checking (CRC-16/CRC-32) and AES encryption with 128-bit or 256-bit keys. These are implemented in hardware and accessible via memory-mapped registers, enabling fast, deterministic checksum validation and secure firmware update decryption without CPU overhead. The MSPM0G1505SRHBR uses these features in bootloader and field-upgrade implementations.

How many analog input channels does the MSPM0G1505SRHBR support?

The MSPM0G1505SRHBR supports 11 external analog input channels for ADC0 and ADC1 combined, as confirmed by the RHB package pinout in Table 5-1 and Section 6.1. This includes dedicated A0_x and A1_x pins routed to the two 12-bit 4Msps ADCs, with flexible analog muxing allowing reconfiguration of certain GPIOs as additional analog inputs where permitted by pin attributes. The MSPM0G1505SRHBR does not support all 17 channels listed for larger packages.

What debug interface does the MSPM0G1505SRHBR provide?

The MSPM0G1505SRHBR provides a 2-pin Serial Wire Debug (SWD) interface via PA19 (SWDIO) and PA20 (SWCLK), compliant with ARM CoreSight standards. This interface supports full breakpoint, watchpoint, and memory access capabilities through standard tools like Code Composer Studio and OpenOCD. No external debug probe is required beyond a compatible SWD adapter, and the MSPM0G1505SRHBR retains SWD functionality across all low-power modes except SHUTDOWN.

Is the MSPM0G1505SRHBR pin-compatible with other MSPM0G150x variants in the same package?

Yes, the MSPM0G1505SRHBR is pin-compatible with MSPM0G1506SRHBR and MSPM0G1507SRHBR in the 32-pin VQFN (RHB) package - sharing identical pin count, function mapping, and mechanical footprint. Differences are limited to flash/RAM size and enabled peripherals (e.g., math accelerator is present in all RHB variants). Firmware developed for MSPM0G1505SRHBR can be reused on higher-memory variants without hardware changes.
