P89LPC938 Datasheet | NXP Semiconductors

.. 8-bit microcontroller with accelerated two-clock 80C51 core 8 k B 3 V byte-erasable Flash with 10-bit A/D converter Rev. 01 - 25 February 2005 Product data sheet 1. General description The P89LPC938 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 P89LPC938 in order to reduce ponent count, board space, and system cost. 2. Features 2.1 Principal Features s 8 k B byte-erasable Flash code memory organized into 1 k B sectors and 64-byte pages. Single-byte erasing allows any byte(s) to be used as non-volatile data storage. s 256-byte RAM data memory and a 512-byte auxiliary on-chip RAM. s 512-byte customer Data EEPROM on chip allows serialization of devices, storage of set-up parameters, etc. s 8-input multiplexed 10-bit A/D converter. Two analog parators with selectable inputs and reference source. s 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 a RTC. s 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. s CCU provides PWM, input capture, and output pare functions. s High-accuracy internal RC oscillator option allows operation without external oscillator ponents. The RC oscillator option is selectable and fine tunable. s 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). s 28-pin TSSOP, PLCC, and HVQFN packages with 23 I/O pins minimum and up to 26 I/O pins while using on-chip oscillator and reset options.
