Product details

What the MSP430F5131IDA brings to a lighting or display controller

The MSP430F5131IDA is a 16-bit MCU running at 25 MHz with 8 KB Flash and 1 KB RAM. It is part of the MSP430F5xx series. The 29 I/O lines and internal oscillator reduce BOM count.

At 25 MHz, the core can execute a PWM update or read an ADC sample within a few hundred nanoseconds. The 8 KB Flash holds a dimming profile table plus communication stack; the 1 KB RAM handles a few frames of buffered data.

No last-time-buy or obsolescence notice applies.

Frequently asked questions

What is MSP430F5131IDA's listed speed?

The MSP430F5131IDA runs at 25 MHz, which is the core clock speed for the MSP430 CPUXV2 processor.

What is the closest pin-compatible alternative to MSP430F5131IDA?

Within the MSP430F5xx family, devices with higher Flash and RAM densities (e.g., 16 KB Flash, 2 KB RAM) share the same 38-TSSOP footprint and peripheral set, offering a drop-in upgrade path without PCB changes.
