FRAM-based 16-bit MCU for industrial sensing and control
Its program memory is 32 KB of FRAM — a non-volatile memory that writes at near-SRAM speed with essentially unlimited endurance, unlike flash. On the analog side it integrates a 10-channel 12-bit ADC and a 4-channel 12-bit DAC, which means a single chip can handle multiple sensor inputs and actuator outputs without external converters.
FRAM endurance — no wear-leveling needed for data logging
FRAM writes at bus speed and tolerates 10¹⁵ write cycles, compared to flash's typical 10⁴–10⁵. For a firmware engineer, this means you can treat the 32 KB FRAM as both code store and data-logging space without managing wear-leveling or write buffers.
The MSP430FR2355TRHAR comes in a 40-VFQFN with exposed pad (6x6 mm body, supplier package 40-VQFN).
