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 counter/timers. Each timer may be configured to toggle a port output upon timer overflow or to become a PWM output. n 23-bit system timer that can also be used as a Real-Time clock. n Two *og comparators with selectable inputs and reference source. n Enhanced UART with fractional baudrate generator, break detect, framing error detection, automatic address detection and versatile interrupt capabilities (P89LPC913, P89LPC914). n SPI communication port. n Internal RC oscillator (factory calibrated to ±1 %) option allows operation without external oscillator components. The RC oscillator option is selectable and fine tunable. n 2.4 V to 3.6 V VDD operating range. I/O pins are 5 V tolerant (may be pulled up or driven to 5.5 V). n Up to 12 I/O pins when using internal oscillator and reset options.
