P89LPC933/934/935/936 8-bit microcontroller with accelerated two-clock 80C51 core 4 k B/8 k B/16 k B 3 V byte-erasable flash with 8-bit ADCs Rev. 8 - 12 January 2011 Product data sheet 1. General description The P89LPC933/934/935/936 is a single-chip microcontroller, 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 P89LPC933/934/935/936 in order to reduce ponent count, board space, and system cost. 2. Features and benefits 2.1 Principal Features - 4 k B/8 k B/16 k B byte-erasable flash code memory organized into 1 k B/2 k B sectors and 64-byte pages. Single-byte erasing allows any byte(s) to be used as non-volatile data storage. - 256-byte RAM data memory. Both the P89LPC935 and P89LPC936 also include a 512-byte auxiliary on-chip RAM. - 512-byte customer data EEPROM on chip allows serialization of devices, storage of setup parameters, etc. (P89LPC935/936). - Dual 4-input multiplexed 8-bit A/D converters/DAC outputs (P89LPC935/936, single A/D on P89LPC933/934).Two analog parators with selectable inputs and reference source. - Two 16-bit counter/timers (each may be configured to toggle a port output upon timer overflow or to bee a PWM output) and a 23-bit system timer that can also be used as an RTC. - Enhanced UART with fractional baud rate generator, break detect, framing error detection, and automatic address detection; 400 k Hz byte-wide I2C-bus munication port and SPI munication port. - Capture/pare Unit (CCU) provides PWM, input capture, and output pare functions (P89LPC935/936). - High-accuracy internal RC oscillator option allows operation without external oscillator ponents. 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). - 28-pin TSSOP,...
