Product details

FRAM MCU for mixed-signal control

It runs at up to 24 MHz and integrates a 10-channel 12-bit ADC and a 4-channel 12-bit DAC, making it a single-chip fit for sensor conditioning and closed-loop control in industrial and automotive auxiliary systems.

32 KB FRAM — no wear-leveling overhead

The 4 KB SRAM handles stack and scratchpad for the 24 MHz core. For designs that previously used external EEPROM, this part absorbs that function on-chip.

On-chip analog chain

Ten 12-bit ADC channels and four 12-bit DAC channels eliminate separate converter ICs for multi-sensor input and actuator output. The internal oscillator (no external crystal needed for basic timing) further reduces BOM count and board area.

Texas Instruments lists this part as Active.

Frequently asked questions

What is the difference between MSP430FR2355TDBTR and MSP430FR2433?

The MSP430FR2433 is a lower-density sibling with 16 KB FRAM and 4 KB RAM, no on-chip DAC, and a smaller 24-pin VQFN package. The MSP430FR2355TDBTR offers double the FRAM (32 KB), four 12-bit DAC channels, and 34 I/O in a 38-TFSOP package — a step up for designs needing more analog output channels or memory headroom.
