P89LPC915/916/917 8-bit microcontrollers with accelerated two-clock 80C51 core 2 k B 3 V flash with 8-bit A/D converter Rev. 05 - 15 December 2009 Product data sheet 1. General description The P89LPC915/916/917 are single-chip microcontrollers, available in low-cost 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 P89LPC915/916/917 in order to reduce ponent count, board space, and system cost. 2. Features 2.1 Principal Features I 2 k B 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. I 256-byte RAM data memory. I Two 16-bit counter/timers. Timer 0 (and Timer 1 - P89LPC917) may be configured to toggle a port output upon timer overflow or to bee a PWM output. I 23-bit system timer that can also be used as a Real-Time clock. I 4-input multiplexed 8-bit A/D converter/single DAC output. Two analog parators with selectable reference. I Enhanced UART with fractional baud rate generator, break detect, framing error detection, automatic address detection and versatile interrupt capabilities. I SPI munication port (P89LPC916). I Internal RC oscillator option allows operation without external oscillator ponents. The RC oscillator (factory calibrated to ±1 %) option is selectable and fine tunable. I 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). I Up to 14 I/O pins when using internal oscillator and reset options (P89LPC916, P89LPC917). 2.2 Additional Features I 14-pin (P89LPC915) and 16-pin (P89LPC916, P89LPC917) TSSOP packages. I A high performance 80C51 CPU provides instruction cycle times of 111 ns to 222 ns for all instructions except multiply and divide when executing at 18 MHz. This is six times the performance of the standard...
