Product details

16-bit MSP430 core with 8 KB Flash — what fits in that memory budget

Industrial temperature grade and on-chip peripherals

The slope A/D converter is a simple, low-pin-count alternative to a full SAR ADC when you need one slow analog channel for a thermistor or potentiometer read.

It is ROHS3 compliant.

Frequently asked questions

What is the MSP430F2131IDWR flash memory size and RAM?

The MSP430F2131IDWR has 8 KB of Flash program memory (8K x 8 plus 256 bytes) and 256 bytes of RAM (256 x 8). That Flash budget handles a modest control loop, UART communication, and a few hundred lines of C — but leaves no room for a full RTOS or a large lookup table.
