Product details
Overview
MSPM0L1304SDYYR from Texas Instruments is an ultra-low-power 32-bit Arm® Cortex®-M0+ microcontroller operating up to 32 MHz, featuring 16 KB flash, 2 KB SRAM, a 12-bit 1.68-Msps ADC with 6 external analog inputs, two zero-drift chopper op-amps, and a high-speed comparator with integrated 8-bit DAC - deployed in battery-powered smart sensors and portable power management systems.
For engineers reviewing the MSPM0L1304SDYYR datasheet, MSPM0L1304SDYYR pinout, MSPM0L1304SDYYR application, or MSPM0L1304SDYYR equivalent, key selection criteria include its 16-pin SOT package, –40°C to 125°C extended temperature rating, 1.62–3.6 V supply range, STANDBY mode consuming only 1.0 µA with full SRAM retention, and support for LIN/IrDA/SMBus protocols via dual UARTs and dual I²C interfaces.
Technical Context
The MSPM0L1304SDYYR integrates a 32-MHz Arm Cortex-M0+ core with on-chip SYSOSC (±1.2% accuracy) eliminating external crystals, and supports intelligent low-power operation across RUN (71 µA/MHz), STOP (44 µA at 32 kHz), STANDBY (1.0 µA with 32-kHz timer active), and SHUTDOWN (61 nA with IO wakeup) modes.
Its analog subsystem includes programmable analog routing between ADC, OPAs, COMP, and DAC; configurable internal VREF (1.4 V or 2.5 V); and dedicated OPA input pins (e.g., OPA0_IN0+, OPA1_IN0−) with 0.5-µV/°C drift and 6-pA input bias current - enabling precision sensor signal conditioning without external components.

FAQ
What is the maximum operating frequency and core type of the MSPM0L1304SDYYR?
The MSPM0L1304SDYYR features an Arm Cortex-M0+ CPU core with a maximum operating frequency of 32 MHz. This enables efficient real-time processing for control loops and communication stacks while maintaining low dynamic power consumption. The core is supported by a 3-channel DMA controller and NVIC for deterministic interrupt handling - essential for time-critical functions in the MSPM0L1304SDYYR.
Does the MSPM0L1304SDYYR support hardware debug interfaces, and which ones?
Yes, the MSPM0L1304SDYYR supports 2-pin Serial Wire Debug (SWD) via dedicated SWCLK (PA20) and SWDIO (PA19) pins. This interface enables full programming, real-time debugging, and memory inspection without occupying additional GPIOs. The MSPM0L1304SDYYR does not support JTAG; SWD is the sole debug protocol, fully compatible with Code Composer Studio and third-party debug probes.
How many analog inputs does the MSPM0L1304SDYYR ADC support, and what is its resolution and speed?
The MSPM0L1304SDYYR integrates a 12-bit analog-to-digital converter (ADC) capable of up to 1.68 million samples per second (Msps), with 6 total external analog input channels (A0–A5). Its configurable internal voltage reference (1.4 V or 2.5 V) ensures consistent conversion accuracy across supply and temperature variations - a key specification confirmed for the MSPM0L1304SDYYR in its device-specific configuration.
What low-power modes are available on the MSPM0L1304SDYYR, and what is the lowest current draw?
The MSPM0L1304SDYYR supports four low-power modes: RUN, STOP, STANDBY, and SHUTDOWN. Its lowest active mode is STANDBY, drawing just 1.0 µA while retaining full SRAM and register contents and running a 32-kHz timer - with wake-up to full 32-MHz operation in 3.2 µs. SHUTDOWN draws only 61 nA but loses SRAM retention, making STANDBY the practical minimum for most always-on sensor applications using the MSPM0L1304SDYYR.
Is the MSPM0L1304SDYYR qualified for extended temperature operation, and what is its supply voltage range?
Yes, the MSPM0L1304SDYYR is qualified for operation from –40°C to +125°C and supports a wide supply voltage range of 1.62 V to 3.6 V. This extended temperature and voltage range is explicitly specified for the MSPM0L1304SDYYR in TI's SLASEX0D datasheet and enables deployment in harsh environments such as automotive under-hood modules, industrial motor drives, and outdoor energy metering - without external voltage regulation or thermal derating.
