2. GENERAL DESCRIPTION
The P80CE559/P83CE559 (hereafter generically referred to as P8x CE559) single-chip 8-bit microcontroller is manufactured in an advanced CMOS process and is a derivative of the 80C51 microcontroller family. The P8x CE559 has the same instruction set as the 80C51. Three versions of the derivative exist:
- Two 8-bit resolution, pulse width modulation outputs
- Five 8-bit I/O ports plus one 8-bit input port shared with analog inputs
- I2C-bus serial I/O port with byte oriented master and slave functions
- Full-duplex UART patible with the standard 80C51
- On-chip watchdog timer
- 15 interrupt...
