P89LPC936

P89LPC933/934/935/936 8-bit microcontroller with accelerated two-clock 80C51 core 4 kB/8 kB/16 kB 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 component count, board space, and system cost. 2. Features and benefits 2.1 Principal features „ 4 kB/8 kB/16 kB byte-erasable flash code memory organized into 1 kB/2 kB 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 comparators 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 become 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 detect...
