Texas Instruments MSPM0G1505SRGZR

Overview

MSPM0G1505SRGZR 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. It integrates two zero-drift chopper op-amps (0.5µV/°C drift), one 12-bit 1Msps DAC with output buffer, three high-speed comparators (32ns propagation delay), and supports extended temperature operation from –40°C to 125°C for industrial motor control and power conversion applications.

For engineers reviewing the MSPM0G1505SRGZR datasheet, MSPM0G1505SRGZR pinout, MSPM0G1505SRGZR application, or MSPM0G1505SRGZR equivalent, key selection considerations include its 48-pin VQFN (7mm × 7mm) package, 1.62V–3.6V supply range, ultra-low-power STOP mode (190µA at 4MHz), STANDBY mode (1.5µA with RTC and SRAM retention), and integrated analog signal chain for sensor conditioning and closed-loop control.

Technical Context

The MSPM0G1505SRGZR implements an Arm Cortex-M0+ core with memory protection unit (MPU) and operates at up to 80MHz via internal PLL or external HFXT (4–48MHz). Its analog subsystem includes programmable analog interconnect between ADCs, OPAs, COMP, DAC, and GPAMP, plus configurable 1.4V/2.5V shared voltage reference and integrated temperature sensor.

Digital peripherals include a 7-channel DMA controller, math accelerator (DIV/SQRT/MAC/TRIG), five timers (including two 16-bit advanced timers with deadband and complementary outputs), two window-watchdog timers, and RTC with calendar mode. Communication interfaces comprise four UARTs (one supporting LIN/IrDA/DALI), two I²C (FM+, 1Mbit/s), and two SPIs (one up to 32Mbits/s).

FAQ

What is the maximum operating frequency of the MSPM0G1505SRGZR?

The MSPM0G1505SRGZR operates at up to 80MHz using its internal PLL or external HFXT oscillator. This frequency is sustained across the full –40°C to 125°C temperature range and 1.62V–3.6V supply voltage, enabling deterministic real-time execution of control algorithms in demanding industrial environments. The MSPM0G1505SRGZR achieves this performance while maintaining low dynamic power consumption (101µA/MHz in RUN mode).

Does the MSPM0G1505SRGZR support simultaneous sampling on both ADCs?

Yes, the MSPM0G1505SRGZR supports true simultaneous sampling on its two 12-bit 4Msps ADCs, allowing concurrent acquisition of up to 17 external analog channels. This capability is critical for vector control applications where phase current and bus voltage must be captured at precisely the same instant. The MSPM0G1505SRGZR implements hardware-triggered synchronization and shared sample-and-hold control to ensure sub-nanosecond timing alignment between ADC conversions.

What analog reference voltages are available on the MSPM0G1505SRGZR?

The MSPM0G1505SRGZR provides a configurable internal shared voltage reference (VREF) with selectable 1.4V or 2.5V outputs, accessible at PA21 (VREF−) and PA23 (VREF+). These references serve all analog peripherals - ADC, DAC, comparators, and OPAs - ensuring consistent scaling and eliminating external reference components. The MSPM0G1505SRGZR also supports external reference injection via the VREF+ pin for applications requiring higher precision or custom voltage levels.

How many GPIOs does the MSPM0G1505SRGZR provide in its 48-pin VQFN package?

The MSPM0G1505SRGZR in the 48-pin VQFN (RGZ) package provides 44 usable GPIOs, as confirmed in Table 5-1 of the device comparison. These include two 5V-tolerant open-drain pins, two 20mA high-drive outputs, and up to five high-speed I/Os capable of >20MHz toggle rates. All GPIOs support programmable pull-up/pull-down, hysteresis, and wake-up from low-power modes - verified in the Pin Attributes table (Section 6.2) of the datasheet.

Is the MSPM0G1505SRGZR qualified for extended temperature operation?

Yes, the MSPM0G1505SRGZR is qualified for operation from –40°C to 125°C (industrial temperature grade, denoted "S" in device nomenclature). This qualification is explicitly stated in the Device Comparison table and supported by thermal characterization data in Section 7.4. The MSPM0G1505SRGZR maintains full specification compliance - including flash read/write, ADC accuracy, and timer resolution - across this full range, making it suitable for under-hood automotive auxiliary modules and industrial motor drives.
