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.","metaTitle":"TI MSP430FR2355TRSMR 16-bit MCU, 24 MHz, 32 KB FRAM","metaDescription":"Texas Instruments MSP430FR2355TRSMR 16-bit MCU with 24 MHz CPU, 32 KB FRAM, 4K x 8 SRAM, 28 I/O, -40 to 105°C.

The MSP430FR2355TRSMR with 32 KB is the cost-optimized choice when the application fits within that memory budget."},{"question":"What are the programming tools for MSP430FR2355TRSMR?","answer":"Standard MSP430 toolchain applies: TI's Code Composer Studio (CCS), IAR Embedded Workbench, and Energia (an Arduino-like IDE).
