P8xC557E8

FUNCTIONAL DESCRIPTION

The P8xC557E8 is a stand-alone high-performance

microcontroller designed for use in real time applications

such as instrumentation, industrial control, medium to

high-end consumer applications and specific automotive

control applications.

In addition to the 80C51 standard functions, the device

provides a number of dedicated hardware functions for

these applications.

The P8xC557E8 is a control-oriented CPU with on-chip

program and Data Memory, but it cannot be extended with

external Program Memory. It can access up to 64 kbytes

of external Data Memory. For systems requiring extra

capability, the P8xC557E8 can be expanded using

standard memories and peripherals.

The functional description of the device is described in:

Chapter 8 “Memory organization”

Chapter 9 “I/O facilities”

Chapter 10 “Pulse Width Modulated outputs”

Chapter 11 “Analog-to-Digital Converter (ADC)”

Chapter 12 “Timers/counters”

Chapter 13 “Serial I/O ports”

Chapter 14 “Interrupt system”

Chapter 15 “Reduced power modes”

Chapter 16 “Oscillator circuits”

Chapter 17 “Reset circuitry”.
