Description
The P89LPC904 is a single-chip microcontroller in a low-cost 8-pin package based on a high performance processor architecture that executes instructions in two to four clocks, six times the rate of standard 80C51 devices.
Features
- 2.1 Principal features
s 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. s 128-byte RAM data memory. s Two 16-bit counter/timers. s 23-bit system timer that can also be used as a Real-Time clock. s 2 -input multiplexed A/D converter/single DAC output. Two analog comparators with selectable reference. s Enhanced UART with fractional baud rate generator, break detect, framing err.
