Product details
Overview
MSPM0L1305SRHBR 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 10 external channels, two zero-drift chopper op-amps, and a high-speed comparator with 8-bit DAC. It targets ultra-low-power battery-powered systems such as smart metering and portable medical devices.
For engineers reviewing the MSPM0L1305SRHBR datasheet, MSPM0L1305SRHBR pinout, MSPM0L1305SRHBR application, or MSPM0L1305SRHBR 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 support for LIN, DALI, and Smart Card protocols via dual UARTs.
Technical Context
The MSPM0L1305SRHBR implements an Arm Cortex-M0+ core with on-chip SYSOSC (±1.2% accuracy, 4–32 MHz) and LFOSC (±3%, 32 kHz), eliminating external crystals. Its analog subsystem integrates programmable gain (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 without CPU intervention.
Digital intelligence includes a 3-channel DMA, event fabric for low-latency peripheral triggering, four 16-bit timers (eight PWM outputs total), and intelligent I/O with wake-from-SHUTDOWN capability on selected pins. Communication is supported by two UARTs (one LIN-capable), two I²C interfaces (one FM+, SMBus/PMBus), and one SPI up to 16 Mbit/s - all operable in STANDBY mode.
Key Specifications
