Product details
Overview
MSPM0L1304TDGS20R from Texas Instruments is a 32-bit Arm® Cortex®-M0+ microcontroller operating at up to 32 MHz, featuring 16 KB flash, 2 KB SRAM, and a 12-bit 1.68-Msps ADC with 8 external analog input channels. It integrates two zero-drift chopper op-amps (0.5 µV/°C drift), one high-speed comparator (32 ns propagation delay), and supports –40°C to 125°C operation on 1.62–3.6 V supply - deployed in battery-powered smart metering and portable power management systems.
For engineers reviewing the MSPM0L1304TDGS20R datasheet, MSPM0L1304TDGS20R pinout, MSPM0L1304TDGS20R application, or MSPM0L1304TDGS20R equivalent, key selection criteria include its 20-pin VSSOP package, 8-channel ADC capability, ultra-low standby current (1.0 µA), dual chopper op-amp architecture, and support for LIN/IrDA/SMBus protocols in STANDBY mode.
Technical Context
This MCU implements an enhanced Arm Cortex-M0+ core with integrated SYSOSC (±1.2% accuracy) eliminating external crystals, and features a dedicated peripheral bus architecture separating CPU, DMA, and low-power peripherals (ULPCLK domain). Its analog subsystem enables programmable signal routing between ADC, OPAs, COMP, and DAC via internal analog muxes.
The device supports five low-power modes - RUN (71 µA/MHz), STOP (44 µA @ 32 kHz), STANDBY (1.0 µA with 32-kHz timer active and 3.2 µs wakeup), SHUTDOWN (61 nA with IO wakeup), and deep-sleep wake-on-analog events - optimized for energy-constrained measurement applications requiring long battery life.

FAQ
What is the maximum ADC sampling rate supported by the MSPM0L1304TDGS20R?
The MSPM0L1304TDGS20R supports a maximum ADC sampling rate of 1.68 million samples per second (Msps) at 12-bit resolution. This performance is achieved using its dedicated ADC clock domain and supports burst-mode acquisition for time-critical applications like switch-mode power supply feedback control. The ADC includes hardware averaging and configurable sample-and-hold timing to maintain accuracy across varying input impedances.
Does the MSPM0L1304TDGS20R include an internal voltage reference for the ADC?
Yes, the MSPM0L1304TDGS20R integrates a programmable internal voltage reference (VREF) that can be configured to 1.4 V or 2.5 V. This reference is routed to the ADC and also available at the PA23 pin for external use. It provides stable, temperature-compensated operation across the full –40°C to 125°C range, eliminating the need for external reference ICs in most precision measurement designs.
How many analog input channels does the MSPM0L1304TDGS20R support?
The MSPM0L1304TDGS20R supports 8 external analog input channels (A0–A7) on its 20-pin VSSOP package. These pins are multiplexed with GPIO and other functions, and all are accessible through the internal analog mux for routing to the ADC, comparators, or op-amp inputs. Channel mapping follows the physical pin assignments defined in the device's signal description table.
What debug interface is supported by the MSPM0L1304TDGS20R?
The MSPM0L1304TDGS20R supports 2-pin Serial Wire Debug (SWD) via dedicated SWCLK and SWDIO pins (PA20 and PA19). This interface enables full JTAG-equivalent debugging - including breakpoints, register inspection, and flash programming - using standard TI XDS110 or third-party CMSIS-DAP debug probes. No external debug header is required beyond the two SWD traces and GND.
What is the lowest power consumption mode available on the MSPM0L1304TDGS20R?
The lowest power mode is SHUTDOWN, consuming just 61 nA while retaining IO wakeup capability. In this mode, all clocks are stopped, SRAM and registers are lost, but selected GPIO pins can trigger a full wakeup. For applications requiring SRAM retention and fast wakeup, STANDBY mode draws 1.0 µA with the 32-kHz timer running and full register/SRAM retention - achieving 3.2 µs wakeup to active execution.
