Product details
Overview
MSPM0L1105TDYYR 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 a 12-bit 1.68-Msps ADC with 10 external channels. It supports –40°C to 105°C operation on 1.62–3.6 V supply and integrates GPAMP, temperature sensor, and dual UARTs - deployed in battery charging systems requiring ultra-low-power wake-up and analog sensing.
For engineers reviewing the MSPM0L1105TDYYR datasheet, MSPM0L1105TDYYR pinout, MSPM0L1105TDYYR application, or MSPM0L1105TDYYR equivalent, key selection criteria include its 16-pin SOT package, 1.0 µA STANDBY current with 32-kHz timer active, 61 nA SHUTDOWN mode with IO wakeup, and support for LIN/IrDA/DALI protocols via UART peripherals.
Technical Context
The MSPM0L1105TDYYR implements an enhanced Arm Cortex-M0+ core with on-chip 4–32 MHz SYSOSC (±1.2% accuracy) eliminating external crystals, and a 32-kHz LFOSC (±3%) for low-power timing. Its power management unit enables five distinct low-power modes - RUN, STOP, STANDBY, SHUTDOWN, and deep-sleep variants - with sub-microamp retention and 3.2 µs wakeup from STANDBY using 32 MHz clock.
Digital subsystem includes a 3-channel DMA, four 16-bit timers (eight total PWM outputs), windowed watchdog, and event fabric for inter-peripheral signaling. Analog integration comprises one configurable 1.4-V/2.5-V internal VREF, GPAMP with differential inputs, and temperature sensor - all accessible within the 16-pin SOT footprint without external components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSPM0L1105TRHB | 32-pin VQFN (5 mm × 5 mm), 28 GPIOs, 10 ADC channels - larger footprint, more I/O, same memory/performance. | Used where board space permits expansion, e.g., evaluation boards or multi-sensor hubs requiring >13 GPIOs. | Select when additional analog/digital resources justify larger package and higher assembly cost. |
| MSPM0L1106TDYYR | Same 16-pin SOT package, but 64 KB flash / 4 KB SRAM - identical pinout and peripherals, doubled program memory. | Preferred for field-upgradable firmware, complex communication stacks (e.g., DALI+BLE coexistence), or future-proofing. | Choose if firmware size exceeds 32 KB or long-term feature scalability is required; no hardware redesign needed. |
Compared with MSPM0L1105TRHB, the MSPM0L1105TDYYR saves board area and cost in space-constrained applications; compared with MSPM0L1106TDYYR, it trades flash capacity for lower unit cost - making it optimal for fixed-function, memory-efficient designs like dedicated chargers or simple sensor nodes.

FAQ
What is the maximum operating frequency of the MSPM0L1105TDYYR?
The MSPM0L1105TDYYR features an Arm Cortex-M0+ core rated for up to 32 MHz operation with zero wait states below 24 MHz and one wait state up to 32 MHz. This frequency is sustained across the full –40°C to 105°C temperature range and 1.62–3.6 V supply, enabled by the integrated ±1.2% accurate SYSOSC - no external crystal required for timing-critical applications.
Does the MSPM0L1105TDYYR support hardware debugging?
Yes, the MSPM0L1105TDYYR supports 2-pin Serial Wire Debug (SWD) via dedicated SWCLK (Pin 12) and SWDIO (Pin 11) pins. These pins are functional in all operating modes except SHUTDOWN and enable full debug visibility - including breakpoints, register inspection, and flash programming - using standard TI tools like Code Composer Studio and compatible JTAG/SWD probes.
How many analog input channels does the MSPM0L1105TDYYR ADC support in the 16-pin SOT package?
In the MSPM0L1105TDYYR (16-pin SOT), the 12-bit ADC supports three external analog input channels: A0 (Pin 15), A1 (Pin 1), and A2 (Pin 16). These correspond to PA27, PA26, and PA25 respectively. Internal sources - temperature sensor and VREF - are also accessible, but only these three pins are routed to package terminals for external signal acquisition.
What is the lowest power consumption mode available on the MSPM0L1105TDYYR?
The lowest power mode is SHUTDOWN, consuming just 61 nA typical with IO wakeup capability. In this mode, the CPU, flash, SRAM, and most peripherals are powered down; only selected GPIOs retain wakeup functionality. The device exits SHUTDOWN in ~10 µs upon configured edge detection - enabling rapid response while maximizing battery life in intermittently active sensor nodes.
Can the MSPM0L1105TDYYR operate without an external crystal?
Yes, the MSPM0L1105TDYYR operates fully without an external crystal. Its integrated 4–32 MHz SYSOSC achieves ±1.2% accuracy across voltage and temperature, and the 32-kHz LFOSC provides ±3% accuracy - both meet timing requirements for UART, SPI, I²C, and real-time control. External crystals are optional and only needed if tighter than ±1.2% frequency stability is mandated.
