Product details
Overview
MSPM0C1103SDSGR from Texas Instruments is an ultra-low-power 32-bit Arm® Cortex®-M0+ microcontroller operating up to 24MHz, featuring 8KB flash, 1KB SRAM, and a 12-bit 1.5Msps ADC with VDD reference-designed for compact battery-powered systems such as smart metering interfaces and portable medical sensors.
For engineers reviewing the MSPM0C1103SDSGR datasheet, MSPM0C1103SDSGR pinout, MSPM0C1103SDSGR application, or MSPM0C1103SDSGR equivalent, key selection criteria include its 8-pin WSON package (2mm × 2mm), -40°C to 125°C operation, 1.62V–3.6V supply range, integrated temperature sensor, and support for UART/I²C/SPI in STANDBY mode.
Technical Context
The MSPM0C1103SDSGR implements a single-core Arm Cortex-M0+ CPU with on-chip 24MHz SYSOSC (±2% to +1.2% accuracy) and 32kHz LFOSC, eliminating external crystals. Its power architecture supports four low-power modes: RUN (87µA/MHz), STOP (311µA at 32kHz), STANDBY (5µA with SRAM retention), and SHUTDOWN (200nA).
Digital peripherals include one 16-bit advanced timer with deadband, two 16-bit general-purpose timers (4 and 2 capture/compare channels), windowed watchdog, and beeper generator (1–8kHz). Analog integration comprises a 10-channel-capable ADC (3 external channels on this 8-pin variant), configurable 1.4V/2.5V internal VREF, on-die temperature sensor, and supply monitor.

FAQ
What is the maximum ADC sampling rate supported by the MSPM0C1103SDSGR?
The MSPM0C1103SDSGR supports 1.5Msps at 12-bit resolution when using VDD as the voltage reference. This rate applies to all three external ADC channels (A0, A3, A6) available on the 8-pin WSON package. The device does not support higher-speed modes like 1.7Msps (10-bit) on this variant due to pin count limitations.
Does the MSPM0C1103SDSGR include hardware debug support?
Yes, the MSPM0C1103SDSGR includes 2-pin Serial Wire Debug (SWD) support via dedicated PA19 (SWDIO) and PA20 (SWCLK) pins. This enables full firmware download, breakpoint debugging, and real-time register inspection using standard TI-supported tools like Code Composer Studio and standalone debug probes.
Can the MSPM0C1103SDSGR operate without an external crystal?
Yes, the MSPM0C1103SDSGR operates without an external crystal. It integrates an internal 24MHz SYSOSC with ±2% to +1.2% accuracy and a 32kHz LFOSC, both qualified for full-spec operation across –40°C to 125°C. No external timing components are required for basic functionality.
What are the absolute maximum ratings for VDD on the MSPM0C1103SDSGR?
The absolute maximum VDD rating for the MSPM0C1103SDSGR is 4.1V. Operation above this voltage may cause permanent damage. The recommended operating range remains 1.62V to 3.6V per specification, and the device is not guaranteed functional outside that range-even if below 4.1V.
How many GPIOs are available on the MSPM0C1103SDSGR package?
The MSPM0C1103SDSGR in the 8-pin WSON (DSG) package provides six usable GPIOs: PA0, PA1, PA24, PA27, PA20, and PA19. All support digital I/O; PA0 and PA1 are 5V-tolerant open-drain; PA24 and PA27 also serve as ADC inputs A3 and A0 respectively.
