P89LPC9107

P89LPC9102/9103/9107 8-bit microcontrollers with two-clock accelerated 80C51 core 1 kB 3 V byte-erasable Flash with 8-bit A/D converter Rev. 02 — 11 April 2005 Product data sheet 1. General description The P89LPC9102/9103/9107 are single-chip microcontrollers in low-cost 10-pin and 14-pin packages based on a high performance processor architecture that executes instructions in two to four clocks, six times the rate of standard 80C51 devices. Many system-level functions have been incorporated into the P89LPC9102/9103/9107 in order to reduce component count, board space, and system cost. 2. Features 2.1 Principal features s 1 kB byte-erasable Flash code memory organized into 256-byte sectors and 16-byte pages. Single-byte erasing allows any byte(s) to be used as non-volatile data storage. s 128-byte RAM data memory. s Two 16-bit timer/counters (P89LPC9102/9107). Two 16-bit timers (P89LPC9103) s 23-bit system timer that can also be used as a RTC. s Four input multiplexed 8-bit A/D converter/single DAC output. One analog comparator with selectable reference. s Enhanced UART with fractional baud rate generator, break detect, framing error detection, automatic address detection and versatile interrupt capabilities (P89LPC9103/9107). s High-accuracy internal RC oscillator option, factory calibrated to 1 %, allows operation without external oscillator components. The RC oscillator option is selectable and fine tunable. s VDD operating range of 2.4 V to 3.6 V with 5 V tolerant I/O pi...
