Texas Instruments MSPM0G1506SRGZR

Overview

MSPM0G1506SRGZR from Texas Instruments is a 32-bit Arm® Cortex®-M0+ microcontroller operating at up to 80MHz, featuring 64KB flash with ECC, 32KB SRAM with hardware parity, and dual 12-bit 4Msps ADCs with 17 external channels-designed for real-time motor control in industrial inverters and uninterruptible power supplies.

For engineers reviewing the MSPM0G1506SRGZR datasheet, MSPM0G1506SRGZR pinout, MSPM0G1506SRGZR application, or MSPM0G1506SRGZR equivalent, key selection criteria include its –40°C to 125°C extended temperature rating, 1.62V–3.6V supply range, integrated zero-drift op-amps, STANDBY mode consuming only 1.5µA, and 48-pin VQFN (RGZ) package with 44 GPIOs.

Technical Context

The MSPM0G1506SRGZR implements an Arm Cortex-M0+ core with memory protection unit (MPU), paired with a dedicated 7-channel DMA controller and math accelerator supporting DIV, SQRT, MAC, and TRIG operations-enabling deterministic execution in closed-loop control loops. Its analog subsystem integrates two simultaneous-sampling ADCs, three high-speed comparators (32ns propagation delay), two chopper op-amps (0.5µV/°C drift), and a programmable gain stage (up to 32×).

Digital peripheral architecture includes two 16-bit advanced timers with deadband and complementary outputs (12 PWM channels), five general-purpose timers (including QEI support and STANDBY-capable variants), dual window-watchdog timers, and RTC with calendar mode-all synchronized via a flexible clock system with PLL, HFXT/LFXT, and internal SYSOSC/LFOSC oscillators.

FAQ

What is the maximum operating frequency and core type of the MSPM0G1506SRGZR?

The MSPM0G1506SRGZR features an Arm Cortex-M0+ CPU core rated for up to 80MHz operation. This frequency is achieved using the internal PLL driven by the HFXT crystal oscillator or SYSOSC. The core includes a memory protection unit (MPU) for secure partitioning of code and data spaces-essential for functional safety compliance in industrial control applications. All timing specifications in the SLASEW9E datasheet are validated at this maximum frequency.

Does the MSPM0G1506SRGZR support simultaneous sampling across both ADCs?

Yes, the MSPM0G1506SRGZR supports true simultaneous sampling on its two independent 12-bit ADCs (ADC0 and ADC1). This capability is hardware-synchronized via shared trigger sources such as timers or software commands, enabling phase-aligned acquisition of motor current and bus voltage-critical for accurate field-oriented control. Each ADC supports up to 17 external input channels, with configurable sample-and-hold timing.

What low-power modes are available on the MSPM0G1506SRGZR and their typical current draw?

The MSPM0G1506SRGZR offers five defined low-power modes: RUN (101µA/MHz), SLEEP (40µA/MHz), STOP (190µA at 4MHz), STANDBY (1.5µA with RTC + SRAM + CPU state retained), and SHUTDOWN (80nA with IO wake-up capability). STANDBY mode is particularly valuable for battery-backed systems requiring timekeeping and rapid wake-up, while SHUTDOWN enables ultra-low leakage in maintenance-free deployments.

Which communication interfaces on the MSPM0G1506SRGZR remain active during STANDBY mode?

Three UART interfaces, both I2C modules, and one SPI interface retain functionality during STANDBY mode on the MSPM0G1506SRGZR. This allows continuous background communication-for example, UART polling for host commands or I2C sensor reads-while the CPU and most peripherals are powered down. Wake-up from STANDBY can be triggered by any enabled peripheral interrupt, including UART RX activity or I2C address match.

What analog peripherals are integrated into the MSPM0G1506SRGZR and how are they interconnected?

The MSPM0G1506SRGZR integrates two zero-drift chopper op-amps (OPA0/OPA1), one general-purpose amplifier (GPAMP), three high-speed comparators (COMP0–COMP2), one 12-bit DAC, and a configurable 1.4V/2.5V internal VREF. These are linked via a programmable analog interconnect matrix-allowing direct routing of ADC outputs to OPA inputs, COMP references to OPA outputs, or DAC signals to GPAMP gain stages-reducing external passive components and PCB area in sensor signal chains.
