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 pins (may be pulled up or driven to 5.5 V). s Up to 10 (P89LPC9107) or eight (P89LPC9102/9103) I/O pins when using internal oscillator and reset options. s Ultra-small 10-pin HVSON package (P89LPC9102/9103).
