Product details
Overview
MSPM0L1305SDGS20R 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 input channels. It integrates two zero-drift chopper op-amps, one high-speed comparator with 8-bit DAC, and supports ultra-low-power STANDBY mode (1.0 µA) with 32-kHz timer retention - ideal for battery-powered sensor nodes and portable power management systems.
For engineers reviewing the MSPM0L1305SDGS20R datasheet, MSPM0L1305SDGS20R pinout, MSPM0L1305SDGS20R application, or MSPM0L1305SDGS20R equivalent, key selection criteria include its 20-pin VSSOP package, –40°C to 125°C extended temperature rating, 1.62–3.6 V supply range, integrated analog signal chain, and support for LIN/IrDA/SMBus protocols in low-power modes.
Technical Context
The MSPM0L1305SDGS20R implements an Arm Cortex-M0+ core with on-chip SYSOSC (±1.2% accuracy) eliminating external crystals, and features a dedicated peripheral bus architecture with AHB/ULPCLK domains enabling concurrent high-speed and ultra-low-power operation. Its analog subsystem includes programmable interconnect between ADC, OPAs, COMP, and VREF, allowing flexible signal routing without external components.
Digital intelligence is delivered via a 3-channel DMA, event fabric for cross-peripheral triggering, four 16-bit timers supporting 8 PWM outputs, and dual UARTs with LIN/Smart Card protocol support - all retaining functionality in STANDBY mode with sub-µs wakeup latency (3.2 µs).
Key Specifications
