Product details
Overview
MSPM0C1104SRUKR from Texas Instruments is a 32-bit Arm® Cortex®-M0+ microcontroller operating at up to 24MHz, featuring 16KB flash, 1KB SRAM, and a 12-bit 1.5Msps ADC with VDD reference-designed for ultra-low-power battery management and smart metering applications in industrial and medical devices.
For engineers reviewing the MSPM0C1104SRUKR datasheet, MSPM0C1104SRUKR pinout, MSPM0C1104SRUKR application, or MSPM0C1104SRUKR equivalent, key selection factors 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 integrated UART/I²C/SPI supporting LIN, DALI, and SMBus protocols.
Technical Context
The MSPM0C1104SRUKR implements an Arm Cortex-M0+ core 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)-optimized for portable measurement systems.
Digital peripherals include one 16-bit advanced timer with deadband and up to 8 PWM channels, two 16-bit general-purpose timers (4 and 2 capture/compare each), a windowed watchdog, and a dedicated 1-channel DMA for ADC transfers. Analog integration comprises a 10-channel ADC, configurable 1.4V/2.5V internal VREF, integrated temperature sensor, and supply monitor.

FAQ
What is the maximum ADC sampling rate supported by the MSPM0C1104SRUKR?
The MSPM0C1104SRUKR supports 1.5Msps at 12-bit resolution when using VDD as the voltage reference. This rate is achievable across all 10 external ADC channels (A0–A9) and enables high-fidelity acquisition for battery voltage tracking and motor current sensing in real-time control loops. The MSPM0C1104SRUKR datasheet confirms this specification under Section 7.11 (ADC) and Table 7-11.
Does the MSPM0C1104SRUKR support debugging without a JTAG interface?
Yes, the MSPM0C1104SRUKR supports full debugging and programming via 2-pin Serial Wire Debug (SWD) using PA19 (SWDIO) and PA20 (SWCLK). This eliminates the need for a 10-pin JTAG connector, reduces PCB footprint, and simplifies bring-up in space-constrained designs. The MSPM0C1104SRUKR functional block diagram (Figure 4-1) and Section 6.3 confirm SWD as the primary debug interface.
What is the purpose of the BEEP pin on the MSPM0C1104SRUKR?
The BEEP pin on the MSPM0C1104SRUKR generates precise 1kHz, 2kHz, 4kHz, or 8kHz square-wave outputs to drive external piezoelectric beepers-enabling audible status alerts in medical devices, security panels, or battery chargers without external tone generators. This function is documented in Section 1 Features and Signal Descriptions (Table 6-3) of the MSPM0C1104SRUKR datasheet.
Can the MSPM0C1104SRUKR operate reliably at 125°C ambient temperature?
Yes, the MSPM0C1104SRUKR is rated for continuous operation from –40°C to 125°C ambient temperature, with a maximum junction temperature of 130°C. Its thermal resistance (RθJA = 52.9°C/W) and low-power modes-including 5µA STANDBY-ensure safe operation in enclosed industrial enclosures or automotive under-hood environments. This is specified in Section 7.3 (Recommended Operating Conditions).
How many I²C interfaces does the MSPM0C1104SRUKR include, and what protocols do they support?
The MSPM0C1104SRUKR includes one I²C interface (I2C0) supporting Fast Mode Plus (1Mbps), SMBus, and PMBus protocols, with wakeup capability from STOP mode. It also features 5V-tolerant open-drain I/O on PA0 (SDA) and PA1 (SCL), enabling direct connection to 5V sensors without level shifters. These capabilities are detailed in Section 1 Features and Table 6-3 (Signal Descriptions).
