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 counter/timers. (P89LPC901 Timer 0 may be configured to toggle a port output upon timer overflow or to become a PWM output.) s 23-bit system timer that can also be used as a Real-Time clock. s Two analog comparators (P89LPC902 and P89LPC903, single analog comparator on P89LPC901). s Enhanced UART with fractional baudrate generator, break detect, framing error detection, automatic address detection and versatile interrupt capabilities (P89LPC903). s High-accuracy internal RC oscillator option allows operation without external oscillator components. The RC oscillator (factory calibrated to ±1 %) option is selectable and fine tunable. s 2.4 V to 3.6 V VDD operating range with 5 V tolerant I/O pins (may be pulled up or driven to 5.5 V).
