8 MHz MSP430 CPUX core with 92 KB flash and LCD drive
The MSP430F4617IPZ runs the MSP430 CPUX 16-bit core at 8 MHz, with 92 KB of program flash and 8 KB of RAM. That memory split handles a moderate firmware image — enough for a metering or display application with a small RTOS or state machine — without pushing the flash boundary. The internal oscillator keeps the BOM simple; no external crystal is needed for the core clock.
Peripheral set — LCD, DMA, and 12-bit ADC
An integrated LCD driver handles segment displays directly — the core does not waste cycles refreshing the glass. The DMA controller moves data between memory and peripherals without CPU intervention, which matters for ADC logging or serial buffering. Twelve 12-bit ADC channels sample analog inputs; the brown-out detector and POR supervisor reset the part cleanly on power loss. 80 general-purpose I/O lines give plenty of headroom for a keypad, external memory, or sensor array. Connectivity covers I²C, SPI, UART/USART, and IrDA — enough for a serial sensor bus, a wireless module, or a debug UART on the same chip.
100-LQFP package and industrial temperature grade
The 100-LQFP (14x14 mm) uses a standard 0.5 mm pitch — no exotic footprint that fights the pick-and-place. The exposed pad is on the bottom; check the MSL rating before the reflow profile, and if the part has been sitting past its floor life, bake it or it popcorns.
Active lifecycle — sourcing posture
The base product number is MSP430F4617; the IPZ suffix identifies the 100-LQFP package and the industrial temperature range. No pin-compatible second source is documented, but the part is a standard TI catalog item with stable supply.
