Texas Instruments MSPM0L1305TDGS20R

Overview

MSPM0L1305TDGS20R 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 8 external analog inputs. It integrates two zero-drift chopper op-amps (0.5 µV/°C drift), one high-speed comparator (32 ns propagation), and supports –40°C to 125°C operation on 1.62–3.6 V supply - ideal for battery-powered smart sensors and power management subsystems.

For engineers reviewing the MSPM0L1305TDGS20R datasheet, MSPM0L1305TDGS20R pinout, MSPM0L1305TDGS20R application, or MSPM0L1305TDGS20R equivalent, key selection criteria include its 20-pin VSSOP package with 17 GPIOs, dual I²C/SPI/UART interfaces supporting low-power STANDBY mode, integrated temperature sensor, and programmable analog signal routing between ADC, OPAs, COMP, and DAC.

Technical Context

The MSPM0L1305TDGS20R implements an Arm Cortex-M0+ core with 32 MHz max frequency and ±1.2% internal SYSOSC, eliminating need for external crystal. Its analog subsystem includes configurable VREF (1.4 V or 2.5 V), dedicated OPA0/OPA1 with 1–32× programmable gain, and COMP0 with integrated 8-bit reference DAC - all accessible via flexible analog mux.

Digital peripherals include four 16-bit timers (8 PWM channels), 3-channel DMA, event fabric, windowed watchdog, and communication interfaces with protocol support including LIN, IrDA, SMBus, and PMBus. Ultra-low-power operation is enabled by RUN (71 µA/MHz), STOP (44 µA @ 32 kHz), STANDBY (1.0 µA with 32-kHz timer active), and SHUTDOWN (61 nA) modes.

FAQ

What is the maximum operating frequency of the MSPM0L1305TDGS20R?

The MSPM0L1305TDGS20R features an Arm Cortex-M0+ CPU with a maximum operating frequency of 32 MHz, supported by an internal 4–32 MHz oscillator with ±1.2% accuracy - eliminating the need for an external crystal while maintaining timing precision for real-time control tasks.

How many analog input channels does the MSPM0L1305TDGS20R support?

The MSPM0L1305TDGS20R supports eight external analog input channels (A0–A7) for its 12-bit, 1.68-Msps ADC. These are mapped to physical pins PA27 through PA20 and PA25–PA22, with A5 and A6 also serving as VREF− and VREF+ terminals for the internal voltage reference.

Does the MSPM0L1305TDGS20R include hardware debug support?

Yes, the MSPM0L1305TDGS20R includes 2-pin Serial Wire Debug (SWD) support via dedicated SWCLK and SWDIO pins, enabling full programming, real-time debugging, and trace capabilities using standard TI or third-party debug probes without consuming additional GPIO resources.

What low-power modes are available on the MSPM0L1305TDGS20R?

The MSPM0L1305TDGS20R offers four low-power modes: RUN (71 µA/MHz), STOP (44 µA @ 32 kHz), STANDBY (1.0 µA with 32-kHz timer active and full SRAM retention), and SHUTDOWN (61 nA with IO wakeup). All modes support fast wake-up - STANDBY recovers in 3.2 µs.

Is the MSPM0L1305TDGS20R pin-compatible with other MSPM0L130x variants in the same package?
