Product details

FRAM-based 16-bit MCU for low-power sensing and control

The MSP430FR2311IPW20 belongs to the MSP430 FRAM family, with 3.75 KB FRAM and 1 KB SRAM.

3.75 KB FRAM — write endurance and non-volatility without the EEPROM tax

The 3.75 KB program space is also usable for non-volatile data storage — config parameters, calibration constants, or logging counters — without wearing out the memory. Combined with 1 KB SRAM, the memory budget fits small control loops, state machines, and data-logging firmware that does not exceed a few thousand lines of C.

20-TSSOP — footprint and layout notes

The 16 I/O lines are accessible on both sides of the body. Decoupling should follow the usual ceramic per supply pin, placed close to the package.

Frequently asked questions

What replaces the MSP430FR2311IPW20?

The natural successor is the MSP430FR2355 in TSSOP-20, which is pin-compatible and steps up to 32KB FRAM. Treat any cross-reference as requiring firmware validation against the datasheet — the peripheral register map and ADC channel mapping must be verified before a drop-in swap.
