16-bit core, 8 MHz ceiling, 24 KB Flash
The MSP430F436IPZR runs a 16-bit MSP430 CPU16 core at 8 MHz — the throughput is set by the core speed and the zero-wait-state Flash access, not by external memory timing. On-chip memory is 24 KB of Flash (24K x 8 + 256B) and 1K x 8 of RAM, enough for a moderate sensor-fusion or LCD-display application without external memory.
100-LQFP footprint and peripheral set
Housed in a 100-LQFP (14x14 mm) package with 48 I/O lines, the device suits designs that need many GPIOs alongside an LCD driver and an 8-channel 12-bit ADC. On-chip peripherals include a brown-out detect, POR, PWM timer, watchdog, and an LCD controller — the LCD segment drive eliminates a separate display driver IC in metering and handheld applications. Serial connectivity covers SPI and UART/USART; the 48 I/O lines provide room for a parallel LCD data bus plus sensor and keypad interfaces.
The base product number is MSP430F436; the IPZR suffix indicates the 100-LQFP package on tape-and-reel for automated assembly.
