Product details
Overview
MSPM0L1305TDYYR from Texas Instruments is a 32-bit Arm® Cortex®-M0+ microcontroller operating at up to 32 MHz, featuring 32 KB flash, 4 KB SRAM, and integrated analog peripherals including a 12-bit 1.68-Msps ADC with 6 external channels, two zero-drift chopper op-amps, and a high-speed comparator with 8-bit reference DAC. It targets ultra-low-power battery management and smart sensing applications in industrial and personal electronics.
For engineers reviewing the MSPM0L1305TDYYR datasheet, MSPM0L1305TDYYR pinout, MSPM0L1305TDYYR application, or MSPM0L1305TDYYR 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 current of 1.0 µA with full SRAM retention, and support for LIN, UART, I²C, and SPI interfaces in low-power operation.
Technical Context
The MSPM0L1305TDYYR implements an enhanced Arm Cortex-M0+ core with on-chip SYSOSC (±1.2% accuracy) eliminating external crystal requirements. Its analog subsystem integrates programmable gain stages (1–32×) into both OPA0 and OPA1, supports configurable internal VREF (1.4 V or 2.5 V), and enables direct analog signal routing between ADC, OPAs, COMP, and DAC via flexible analog muxing.
Digital intelligence includes a 3-channel DMA, four 16-bit timers supporting 8 PWM outputs, event fabric signaling, and a windowed watchdog timer. Low-power operation is enforced across RUN (71 µA/MHz), STOP (44 µA @ 32 kHz), STANDBY (1.0 µA with 32-kHz timer active), and SHUTDOWN (61 nA with IO wakeup) modes - all retaining critical state without external supervision.

FAQ
What is the maximum ADC sampling rate supported by the MSPM0L1305TDYYR?
The MSPM0L1305TDYYR supports a maximum ADC sampling rate of 1.68 million samples per second (Msps). This performance is achieved with the 12-bit successive approximation register (SAR) ADC and applies to single-channel acquisition. The device allocates up to 6 external analog input channels in the 16-pin SOT package, and the high throughput enables real-time signal analysis for applications such as motor current sensing or audio pre-processing.
Does the MSPM0L1305TDYYR support hardware-based cryptographic operations?
No, the MSPM0L1305TDYYR does not include dedicated cryptographic accelerators (e.g., AES, SHA, or TRNG). It relies on software libraries for lightweight encryption tasks. However, it supports secure boot via ROM-based bootloader validation and flash lock bits to prevent unauthorized firmware access - providing foundational security for firmware integrity in resource-constrained endpoints.
Can the MSPM0L1305TDYYR operate without an external crystal oscillator?
Yes, the MSPM0L1305TDYYR operates without an external crystal oscillator. It integrates an internal 4–32 MHz SYSOSC with ±1.2% accuracy and a 32-kHz LFOSC with ±3% accuracy. These oscillators are factory-trimmed and sufficient for UART communication (with appropriate oversampling), ADC timing, and general-purpose timing - eliminating BOM cost and PCB area for external crystals in most applications.
How many analog input channels are accessible on the MSPM0L1305TDYYR in the 16-pin SOT package?
The MSPM0L1305TDYYR in the 16-pin SOT (DYY) package provides 6 dedicated external analog input channels: A0 through A5 (mapped to pins PA27, PA26, PA25, PA24, PA23, and PA22 respectively). These channels connect directly to the 12-bit ADC and support programmable sampling sequences, hardware averaging, and injection modes for priority conversions.
What debug interface does the MSPM0L1305TDYYR support, and how many pins are required?
The MSPM0L1305TDYYR supports 2-pin Serial Wire Debug (SWD), using SWCLK (PA20) and SWDIO (PA19) pins. This interface enables full JTAG-equivalent debugging - including breakpoints, memory inspection, and real-time variable watch - while consuming only two dedicated pins and leaving all other GPIOs available for application use during development and field deployment.
