Product details

Mixed-signal MCU with on-chip ADC and DAC

The MSP430FG477IPN: The distinguishing feature of this variant is its on-chip data converter set: a 5-channel 16-bit ADC and a 2-channel 12-bit DAC, which allows direct connection of analog sensors and actuators without an external analog front-end IC.

Peripheral set and connectivity

The device includes a brown-out detect and reset circuit, an LCD driver, PWM outputs, and a watchdog timer. With 48 general-purpose I/O lines in an 80-LQFP package, it provides enough pin count for moderate-complexity control panels and sensor hubs.

Frequently asked questions

What is the closest pin-compatible alternative to the MSP430FG477IPN?

Within the MSP430x4xx family, the MSP430FG478 and MSP430FG479 are pin-compatible variants with larger Flash memory options (48 KB and 60 KB respectively). They share the same 80-LQFP footprint, same ADC/DAC peripheral set, and same supply and temperature ratings. The trade-off is program memory density versus cost; the FG477 at 32 KB is the entry point for this mixed-signal subfamily.
