P89LPC931FDH [Rochester]

The P89LPC930/931 are single-chip microcontrollers based on a high-performance 80C51 core that executes instructions in two to four clocks, offering six times the performance of standard 80C51 devices. They feature 4 kB or 8 kB Flash memory, 256-byte RAM, and a wide range of peripherals including UART, I2C, SPI, analog comparators, timers, and watchdog timer. Designed for high-integration, low-cost applications, they reduce component count and board space while providing flexible I/O options and low-power modes.
