FRAM memory and 16-bit core for low-power sensing
The MSP430FR2633IDAR is a 16-bit MCU from the MSP430™ FRAM family, built around the MSP430 CPU16 core clocked at 16 MHz. The 15.5 KB FRAM program memory is the standout feature — it writes at byte level without a separate erase cycle, so data logging and parameter storage happen in-place without wear-leveling overhead. With 4K x 8 of RAM and 19 general-purpose I/O lines, this part handles sensor fusion and control loops in a single chip. The 8-channel 10-bit ADC captures analog inputs directly — no external converter needed for thermistor or strain-gauge signals.
Industrial temperature range and serial connectivity
Serial interfaces include I²C, SPI, UART, and IrDA — enough to talk to an external radio module, a display driver, or a host processor over a single bus.
