n 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. n 128-byte RAM data memory. n Two 16-bit timer/counters (P89LPC9102/9107). Two 16-bit timers (P89LPC9103) n 23-bit system timer that can also be used as a RTC. n Four input multiplexed 8-bit A/D converter/single DAC output. One *og comparator with selectable reference. n Enhanced UART with fractional baud rate generator, break detect, framing error detection, automatic address detection and versatile interrupt capabilities (P89LPC9103/9107). n 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. n VDD operating range of 2.4 V to 3.6 V with 5 V tolerant I/O pins (may be pulled up or driven to 5.5 V). n Up to 10 (P89LPC9107) or eight (P89LPC9102/9103) I/O pins when using internal oscillator and reset options. n Ultra-*all 10-pin HVSON package (P89LPC9102/9103). 14-pin TSSOP (P89LPC9107).
