Product details

FRAM instead of Flash — what that changes on the BOM

Its program memory is 32 KB of FRAM, not Flash — that means unified memory for code and data, write endurance of 10^15 cycles, and single-cycle writes at full speed. No erase-before-write penalty, no sector management for nonvolatile data storage. The 4K x 8 SRAM handles stack and scratchpad.

Package and PCB integration

Housed in a 32-VFQFN with exposed pad (4x4 mm body, supplier package 32-VQFN). Surface-mount only; 28 general-purpose I/O are available.

Frequently asked questions

What is the difference between MSP430FR2355TRSMR and MSP430FR2356?

The MSP430FR2356 is a higher-density sibling in the same FRAM series — it doubles the program memory to 64 KB while keeping the same 24 MHz core, 4K x 8 SRAM, 28 I/O count, and 32-VQFN package. The MSP430FR2355TRSMR with 32 KB is the cost-optimized choice when the application fits within that memory budget.

What are the programming tools for MSP430FR2355TRSMR?

Standard MSP430 toolchain applies: TI's Code Composer Studio (CCS), IAR Embedded Workbench, and Energia (an Arduino-like IDE). Debug and programming via the SBW (Spy-Bi-Wire) two-wire JTAG interface using a TI LaunchPad or standalone debugger like the MSP-FET.
