The P89LPC912/913/914 are single-chip microcontrollers in low-cost 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 P89LPC912/913/914 in order to reduce component count, board space, and system cost.
P89LPC913 Features
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. 128-byte RAM data memory. Two 16-bit counter/timers. Each timer may be configured to toggle a port output upon timer overflow or to become a PWM output. 23-bit system timer that can also be used as a Real-Time clock. Two analog comparators with selectable inputs and reference source. Enhanced UART with fractional baudrate generator, break detect, framing error detection, automatic address detection and versatile interrupt capabilities (P89LPC913, P89LPC914). SPI communication port. High-accuracy internal RC oscillator option allows operation without external oscillator components.The RC oscillator option is selectable and fine tunable. 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). Up to 12 I/O pins when using internal oscillator and reset options.
