Product details
Overview
MSPM0L1305SRGER from Texas Instruments is an ultra-low-power 32-bit Arm® Cortex®-M0+ microcontroller operating up to 32 MHz, featuring 32 KB flash, 4 KB SRAM, a 12-bit 1.68-Msps ADC with 10 external channels, two zero-drift chopper op-amps (0.5 µV/°C drift, 6-pA bias), and integrated temperature sensor - deployed in battery-powered smart metering and portable medical sensors.
For engineers reviewing the MSPM0L1305SRGER datasheet, MSPM0L1305SRGER pinout, MSPM0L1305SRGER application, or MSPM0L1305SRGER equivalent, key selection criteria include its 32-pin VQFN (RHB) 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 32-kHz timer, and dual UART/I²C/SPI interfaces supporting LIN, SMBus, and PMBus protocols.
Technical Context
The MSPM0L1305SRGER integrates a high-accuracy ±1.2% internal SYSOSC (4–32 MHz) and ±3% LFOSC (32 kHz), eliminating external crystals. Its analog subsystem enables programmable connections between ADC, OPAs, COMP, and DAC - including OPA gain configuration (1×–32×) and COMP with integrated 8-bit reference DAC (32-ns propagation delay).
Digital intelligence includes a 3-channel DMA, event fabric for low-latency peripheral signaling, four 16-bit timers (8 PWM channels total), and windowed watchdog. Power management supports five modes: RUN (71 µA/MHz), STOP (151 µA @ 4 MHz), STANDBY (1.0 µA), and SHUTDOWN (61 nA with I/O wakeup).

FAQ
What is the maximum operating frequency and core architecture of the MSPM0L1305SRGER?
The MSPM0L1305SRGER features an Arm Cortex-M0+ CPU core with a maximum operating frequency of 32 MHz. It uses the Thumb-2 instruction set and includes a nested vectored interrupt controller (NVIC) for deterministic real-time response. This architecture balances computational throughput with ultra-low power consumption, making it suitable for time-critical sensor processing in constrained energy environments.
Does the MSPM0L1305SRGER support hardware debug, and what interface is used?
Yes, the MSPM0L1305SRGER supports 2-pin serial wire debug (SWD) via dedicated SWCLK and SWDIO pins (PA20 and PA19). This interface enables full firmware download, breakpoint setting, register inspection, and real-time variable monitoring without requiring additional pins or complex cabling - critical for rapid development and field diagnostics in space-limited designs.
How many analog input channels does the MSPM0L1305SRGER ADC support, and what is its sampling rate?
The MSPM0L1305SRGER integrates a single 12-bit analog-to-digital converter (ADC0) supporting up to 10 external analog input channels (A0–A9). Its maximum sampling rate is 1.68 million samples per second (Msps), enabling high-fidelity capture of fast transients in power quality monitoring or motor current analysis applications.
What low-power modes are available on the MSPM0L1305SRGER, and what is the lowest current draw?
The MSPM0L1305SRGER offers RUN, STOP, STANDBY, and SHUTDOWN modes. The lowest active-retention mode is STANDBY, drawing just 1.0 µA while maintaining full SRAM and register contents and keeping a 32-kHz timer operational. Wakeup to full 32-MHz operation occurs in 3.2 µs - ideal for duty-cycled sensor nodes requiring sub-second responsiveness.
Is the MSPM0L1305SRGER pin-compatible with other devices in the MSPM0L130x family?
Yes, the MSPM0L1305SRGER in the 32-pin VQFN (RHB) package shares identical pinout and electrical characteristics with other RHB-packaged variants including MSPM0L1303SRGER, MSPM0L1304SRGER, and MSPM0L1306SRGER.
