The MSP430F5247IRGCR is a 16-bit microcontroller from the MSP430F5xx family, with a 25 MHz core, 64 KB Flash, 8 KB RAM, 53 I/O, 12-channel 10-bit ADC, 1.8 V to 3.6 V supply, and -40 to 85 °C range.
25 MHz CPUXV2 — throughput for control loops
The 25 MHz clock on the 16-bit core delivers throughput for a PID loop or a Modbus packet handler.
64 KB Flash, 8 KB RAM — what it fits
64 KB Flash suits a firmware image with a real-time kernel, communication stack, and moderate application logic. The 8 KB RAM handles a few hundred bytes of sensor buffers and a modest call stack; if your application needs a large frame buffer or multi-packet FIFO, budget the RAM tighter or look up the density variants in the MSP430F5xx family.
Industrial temperature range and on-chip peripherals
Rated for -40 to 85 °C, the MSP430F5247IRGCR is specified for industrial enclosures, outdoor telecom cabinets, and under-hood-adjacent environments where condensation and thermal cycling are expected. On-chip peripherals include brown-out detect, POR, DMA, PWM, and a watchdog timer — enough to run a standalone controller without an external supervisor. Connectivity covers I²C, IrDA, SPI, and UART/USART, which covers the common sensor and actuator bus interfaces in a distributed control panel.
