Product details
Overview
MSPM0C1103SDYYR from Texas Instruments is an ultra-low-power 32-bit Arm® Cortex®-M0+ microcontroller operating at up to 24MHz, featuring 8KB flash, 1KB SRAM, and a 12-bit 1.5Msps ADC with VDD reference-designed for battery-powered industrial sensing and power management in compact SOT-16 packages.
For engineers reviewing the MSPM0C1103SDYYR datasheet, MSPM0C1103SDYYR pinout, MSPM0C1103SDYYR application, or MSPM0C1103SDYYR equivalent, this page delivers verified package mapping (16-pin SOT), confirmed low-power modes (5µA STANDBY), analog integration (10-channel ADC), debug interface (2-pin SWD), and real-world substitution guidance for cost-sensitive embedded designs.
Technical Context
The MSPM0C1103SDYYR implements a single-core Arm Cortex-M0+ CPU with tightly coupled AHB bus architecture, supporting up to 24MHz operation using its internal ±2% SYSOSC-eliminating external crystal requirements. Its peripheral subsystem integrates dedicated DMA for ADC transfers, CRC-16 acceleration, and three independent timer groups: one 16-bit advanced timer with deadband support, two 16-bit general-purpose timers, and a windowed watchdog.
Communication is handled by one UART (LIN/IrDA/DALI/Manchester capable), one I²C (FM+, SMBus, PMBus), and one SPI (up to 12Mbps), all configurable for low-power STOP/STANDBY wake-up. Analog resources include a 10-channel ADC with selectable 1.4V/2.5V internal VREF, integrated temperature sensor, supply monitor, and beeper output for audible alerts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0+, 24MHz max-enables deterministic real-time control without external clock source. |
| Memory | 8KB flash / 1KB SRAM-sufficient for firmware + runtime variables in compact power-constrained applications. |
| ADC Performance | 12-bit, 1.5Msps at 12-bit (VDD reference)-supports high-speed voltage/current sampling in battery chargers or power supplies. |
| Operating Range | –40°C to 125°C, 1.62V–3.6V supply-validated for automotive under-hood and industrial ambient conditions. |
| Low-Power Modes | STANDBY: 5µA with SRAM retention-enables multi-year battery life in always-on monitoring nodes. |
| Package | 16-pin SOT (DYY), 4.2mm × 3.26mm footprint-fits space-constrained PCB layouts in portable electronics. |
| Debug Interface | 2-pin Serial Wire Debug (SWD)-reduces test point count while enabling full firmware development and field updates. |
Pinout & Package
Package: 16-pin SOT (DYY), 4.2mm × 3.26mm body size with gull-wing leads; thermal performance characterized per JEDEC JESD51-7 (RθJA = 98.2°C/W for TSSOP-equivalent layout).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PA0 | I²C0_SDA / BEEP / TIMG8_C0 | Open-drain I/O usable as I²C data line or beeper driver-no external pull-up required for I²C bus. |
| PA1 / NRST | Reset input (active-low) | Asynchronous reset pin; must be pulled high to VDD for reliable startup-internal weak pull-up insufficient. |
| VDD | Power supply input | 1.62V–3.6V main supply; requires ≥10µF low-ESR capacitor placed adjacent to pin for stable operation. |
| VSS | Ground reference | Primary return path for analog/digital domains; connects to exposed thermal pad on compatible packages (not applicable to SOT). |
| PA20 / SWCLK | SWD clock input | Drives debug clock during programming and real-time tracing-requires clean 10MHz–50MHz square wave. |
| PA19 / SWDIO | SWD bidirectional data | Single-wire debug channel carrying both command and response traffic-supports full memory access and breakpoint control. |
| A0–A5 | ADC analog inputs | 6 dedicated analog input pins (A0–A5) mapped to PA27, PA28, PA26, PA25, PA24, PA23-support simultaneous sampling via DMA trigger. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated VREF | Selectable 1.4V or 2.5V internal reference enables precise ADC measurements independent of VDD fluctuations. |
| Dedicated ADC DMA | 1-channel DMA controller automatically transfers ADC results to SRAM-reduces CPU load and latency in continuous sampling. |
| Advanced Timer Deadband | 16-bit advanced timer supports programmable deadtime insertion between complementary PWM outputs-prevents shoot-through in motor/gate drivers. |
| UART Low-Power Mode | UART retains LIN/IrDA/DALI protocol support while waking from STANDBY mode-ideal for always-listening communication nodes. |
| 5V-Tolerant IOs | Two open-drain pins (PA0, PA1) tolerate 5V logic levels-simplifies interfacing with legacy peripherals without level shifters. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSPM0C1104SDYYR | 16KB flash, 10 ADC channels, same 16-pin SOT package | Supports larger firmware images and additional analog inputs-suitable when code size exceeds 8KB or >6 ADC channels needed | Select when future firmware expansion or higher channel-count sensing is anticipated; identical pinout and debug interface. |
| MSPS003F3SPW20R | 8KB flash, 1KB SRAM, 20-pin TSSOP, 9 ADC channels | Larger package with more GPIOs and ADC inputs-better for prototyping or designs requiring signal routing flexibility | Choose when board layout allows 20-pin footprint and additional I/Os simplify interconnect; not pin-compatible with DYY. |
Compared with MSPM0C1104SDYYR, the MSPM0C1103SDYYR trades flash capacity and ADC channel count for lower unit cost in volume production; versus MSPS003F3SPW20R, it offers superior space efficiency but fewer GPIOs-making it optimal for miniaturized, cost-sensitive power management ICs.

FAQ
What is the maximum ADC sampling rate supported by MSPM0C1103SDYYR?
The MSPM0C1103SDYYR supports 1.5Msps at 12-bit resolution when using VDD as the voltage reference. This rate is achievable across all 10 ADC channels with proper clock configuration and DMA buffering-enabling high-fidelity waveform capture in power quality analyzers or motor current sensing.
Does MSPM0C1103SDYYR support crystal-less operation?
Yes, MSPM0C1103SDYYR operates crystal-less using its internal 24MHz SYSOSC with ±2% accuracy over temperature and voltage. This eliminates external crystal components and associated load capacitors-reducing BOM cost and PCB area while maintaining sufficient timing precision for UART, I²C, and SPI communication.
How many GPIOs are available on the MSPM0C1103SDYYR in the 16-pin SOT package?
The MSPM0C1103SDYYR provides 14 GPIOs in the 16-pin SOT (DYY) package. Two pins are dedicated to power (VDD, VSS), and the remaining 14-including PA0 through PA28 mappings-support configurable digital I/O, analog input, timer functions, and communication interfaces as defined in the pin attributes table.
What low-power modes does MSPM0C1103SDYYR offer, and what is the lowest current draw?
MSPM0C1103SDYYR offers RUN, STOP, STANDBY, and SHUTDOWN modes. The lowest active current is 5µA in STANDBY mode with SRAM retention-enabling years of operation on coin-cell batteries in wireless sensor nodes while preserving critical state data for rapid wake-up.
Is MSPM0C1103SDYYR pin-compatible with other devices in the MSPM0C110x family?
No-MSPM0C1103SDYYR uses the 16-pin SOT (DYY) package, while other variants like MSPM0C1104SDGS20R use 20-pin VSSOP and MSPM0C1103SDSGR uses 8-pin WSON. Pin compatibility exists only within the same package type (e.g., MSPM0C1103SDYYR and MSPM0C1104SDYYR share identical 16-pin SOT pinout).
