116 KB flash, 8 KB RAM — memory budget for mixed-signal control
The MSP430F2618TPM packs 116 KB of program flash and 8 KB of RAM on a 16-bit CPU16 core clocked at 16 MHz. That memory split suits a single-chip controller that runs a sensor-fusion algorithm, a Modbus stack, and a PID loop without needing external memory — the 8 KB RAM holds a few hundred data points for a 1 kHz logging rate. On-chip data converters — an 8-channel 12-bit ADC and a dual 12-bit DAC — let it close the analog loop directly: read a current shunt or thermistor, compute the correction, and drive an actuator output without an external converter. The 48 general-purpose I/O lines, combined with I²C, SPI, UART, IrDA, and LIN connectivity, cover sensor buses, debug UART, and automotive LIN node interfaces on a single part.
The internal oscillator and brown-out detect (BOD) keep the core running through supply dips down to the reset threshold.
Package and board-fit note — 64-LQFP
Housed in a 64-LQFP with a 10x10 mm body and 0.50 mm pitch. Surface-mount only — no through-hole variant. The fine pitch demands controlled solder-paste deposition and a reflow profile matching JEDEC MSL level (not listed, but typical for this package class).
