It belongs to the MSP430x4xx series, the LCD-drive branch of the family — the segment driver is integrated, so a water-meter or gas-meter board saves an external display controller and the associated SPI bus overhead. ## 32 KB Flash and 2K RAM — firmware envelope for a metrology stack The data converter block is the headline peripheral: a 5-channel 16-bit ADC and a single 12-bit DAC — the 16-bit ADC gives 0.0015 % resolution at a 3.6 V reference, enough for a class-0.5 energy-meter current channel without an external amplifier. ## 80-LQFP 12x12 — a hand-solderable footprint with 48 GPIO The 80-lead LQFP (12x12 mm body) has a 0.5 mm pitch — fine enough for a two-layer board with careful fan-out, but wide enough that a rework station with a hot-air pencil can replace the part without a pre-heater. The 48 I/O lines leave room for a parallel LCD data bus plus a keypad matrix and still have pins for the ADC inputs. The internal oscillator saves the external crystal for the real-time clock, though the 8 MHz ceiling limits the DCO to that speed. ## Active lifecycle — stable supply for production BOMs The base product number is MSP430F477, and the IPN suffix indicates the 80-LQFP tray package.","metaTitle":"TI MSP430F477IPN 16-bit MCU, 8MHz, 32KB Flash, 80-LQFP","metaDescription":"Texas Instruments MSP430F477IPN active 16-bit MCU, 8MHz MSP430 CPU16, 32KB Flash, 2K RAM, 5x16b ADC, 80-LQFP.
