16 MHz core, 32 KB flash — sizing the memory envelope
The MSP430G2744IDA38 runs a 16-bit MSP430 CPU16 core at 16 MHz. With 32 KB of on-chip flash and 1 KB of RAM, the memory split suits control loops and sensor fusion that keep the code and small data sets on-chip rather than paging external memory.
Peripheral set and I/O count for sensor and actuator nodes
The 12-channel 10-bit ADC samples analog inputs from thermistors, potentiometers, or current-sense resistors; the 10-bit resolution is adequate for 0.1% accuracy over a 3.3 V reference.
Industrial temperature grade and on-chip supervision
Built-in brown-out detect, power-on reset, and watchdog timer mean the part can recover from a glitch on the supply rail without an external supervisor IC — a BOM simplification for cost-sensitive boards.
ROHS3 compliant per, with the base product number MSP430G2744 covering multiple package variants for alternate sourcing within the same die family.
