Product details
Overview
MSPM0C1103SRUKR from Texas Instruments is an ultra-low-power 32-bit Arm® Cortex®-M0+ microcontroller operating at up to 24MHz, featuring 8KB flash, 1KB SRAM, a 12-bit 1.5Msps ADC with VDD reference, and integrated temperature sensor - deployed in battery-powered smart meters and portable medical sensors.
For engineers reviewing the MSPM0C1103SRUKR datasheet, MSPM0C1103SRUKR pinout, MSPM0C1103SRUKR application, or MSPM0C1103SRUKR equivalent, key selection criteria include its 20-pin WQFN (3mm × 3mm) package, -40°C to 125°C extended temperature range, 1.62V–3.6V supply, 5µA STANDBY current with SRAM retention, and dual UART/I²C/SPI interfaces supporting LIN, SMBus, and low-power standby wakeup.
Technical Context
The MSPM0C1103SRUKR integrates an Arm Cortex-M0+ core with dedicated 1-channel DMA for ADC transfers, three 16-bit timers (including one advanced timer with deadband support), and a windowed watchdog timer. Its clock system combines a ±2% internal 24MHz SYSOSC and 32kHz LFOSC, eliminating external crystals.
Analog subsystem includes a 10-channel ADC with configurable 1.4V/2.5V internal VREF, on-chip temperature sensor, supply monitor, and two 5V-tolerant open-drain I/Os. Digital I/Os support flexible pin-muxing via PINCM registers, with hysteresis, pull-up/down, and drive strength control.

FAQ
What is the maximum ADC sampling rate supported by the MSPM0C1103SRUKR?
The MSPM0C1103SRUKR supports 1.5Msps at 12-bit resolution when using VDD as the voltage reference. This rate is achievable across all 10 external ADC channels and is specified under recommended operating conditions (1.62V–3.6V, –40°C to 125°C). The MSPM0C1103SRUKR datasheet confirms this performance in Section 7.11.
Does the MSPM0C1103SRUKR include an internal voltage reference for the ADC?
Yes, the MSPM0C1103SRUKR includes a configurable internal voltage reference (VREF) selectable between 1.4V and 2.5V via register settings. This allows stable ADC conversions independent of VDD fluctuations, and is documented in Section 1.7 of the MSPM0C110x datasheet.
What debug interface does the MSPM0C1103SRUKR support?
The MSPM0C1103SRUKR supports 2-pin Serial Wire Debug (SWD) using PA19 (SWDIO) and PA20 (SWCLK). This interface enables full firmware download, real-time debugging, and register access without requiring additional pins or protocols like JTAG.
Can the MSPM0C1103SRUKR operate across the full industrial temperature range?
Yes, the MSPM0C1103SRUKR is rated for –40°C to 125°C ambient temperature operation, with junction temperature limited to 130°C. This is verified in Section 7.3 (Recommended Operating Conditions) and applies to all package variants including the RUK WQFN used in MSPM0C1103SRUKR.
How many general-purpose I/O pins does the MSPM0C1103SRUKR provide?
The MSPM0C1103SRUKR provides up to 18 GPIOs in its 20-pin WQFN (RUK) package. Two of these - PA0 and PA1 - are 5V-tolerant open-drain I/Os, while the remaining 16 support standard-drive digital I/O with programmable pull-up/pull-down and hysteresis.
