Product details
Overview
MSPM0C1104SDSGR from Texas Instruments is an ultra-low-power 32-bit Arm® Cortex®-M0+ microcontroller operating at up to 24MHz, featuring 16KB 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 MSPM0C1104SDSGR datasheet, MSPM0C1104SDSGR pinout, MSPM0C1104SDSGR application, or MSPM0C1104SDSGR equivalent, key selection factors include its 8-pin WSON package (2mm × 2mm), -40°C to 125°C operation, 1.62V–3.6V supply range, and support for UART/I²C/SPI interfaces in STANDBY mode with 5µA retention current.
Technical Context
The MSPM0C1104SDSGR implements a single-core Arm Cortex-M0+ CPU with on-chip 24MHz SYSOSC (±2% accuracy) and 32kHz LFOSC, eliminating external crystals. Its power management unit enables 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 and up to 8 PWM channels, two 16-bit general-purpose timers, a windowed watchdog, and a dedicated 1-channel DMA for ADC transfers. Analog integration comprises a 10-channel-capable ADC (3 external channels available in this 8-pin variant), configurable 1.4V/2.5V internal VREF, and on-die temperature sensing.

FAQ
What is the maximum ADC sampling rate supported by the MSPM0C1104SDSGR?
The MSPM0C1104SDSGR supports 1.5Msps at 12-bit resolution when using VDD as the voltage reference. This rate is achievable across its three available external ADC channels (A0, A5, A6), enabling high-fidelity acquisition of fast-changing analog signals such as current sense waveforms in switching power supplies.
Does the MSPM0C1104SDSGR require an external crystal oscillator?
No, the MSPM0C1104SDSGR does not require an external crystal. It integrates a 24MHz internal SYSOSC with ±2% accuracy and a 32kHz LFOSC, both qualified for full operational use across –40°C to 125°C - eliminating BOM cost and layout complexity associated with external timing components.
How many GPIO pins are available on the MSPM0C1104SDSGR in its 8-pin WSON package?
The MSPM0C1104SDSGR in the 8-pin WSON (DSG) package provides 6 GPIO pins: PA0, PA1/NRST, PA24, PA27, PA20, and PA28. All support digital I/O functions; PA0 and PA1 are 5V-tolerant open-drain, while the others are standard-drive with configurable pullup/pulldown.
What low-power modes does the MSPM0C1104SDSGR support, and what is the lowest current consumption?
The MSPM0C1104SDSGR supports RUN, STOP, STANDBY, and SHUTDOWN modes. Its lowest active-retention mode is STANDBY at 5µA with full 1KB SRAM retention. In SHUTDOWN mode, it draws only 200nA - suitable for long-term storage or infrequent wake-up scenarios.
Can the MSPM0C1104SDSGR interface with I²C peripherals operating at 5V logic levels?
Yes - the MSPM0C1104SDSGR features two 5V-tolerant open-drain I/O pins (PA0 and PA1), which safely interface with standard 5V I²C buses. These pins accept up to 5.5V input while operating from a 1.62–3.6V VDD supply, eliminating the need for external level translators in mixed-voltage systems.
