GENERAL DESCRIPTION
The 8-bit microcontrollers P80C557E8, P83C557E8 and
P87C557E8 - hereafter referred to as P8xC557E8 - are
manufactured in an advanced CMOS process and are
derivatives of the 80C51 microcontroller family.
The P8xC557E8 contains a volatile 2048 bytes read/write
Data Memory, five 8-bit I/O ports, one 8-bit input port, two
16-bit timer/event counters (identical to the timers of the
80C51), an additional 16-bit timer coupled to capture and
compare latches, a 15-source, two-priority-level,
nested interrupt structure, an 8-input ADC, a dual
Digital-to-Analog Convertor (DAC), Pulse Width
Modulated interface, two serial interfaces (UART and
I
2
C-bus), a Watchdog Timer, an on-chip oscillator and
timing circuits.
The P8xC557E8 is available in 3 versions:
P80C557E8: ROMless version
P83C557E8: containing a non-volatile 64 kbytes mask
programmable ROM
P87C557E8: containing 64 kbytes programmable
EPROM/OTP.
The P8xC557E8 is a control-oriented CPU with on-chip
Program and Data Memory; 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 TTL compatible memories and peripherals.
In addition, the P8xC557E8 has two software selectable
reduced power modes: Idle mode and Power-down mode.
The Idle mode freezes the CPU while allowing the RAM,
timers, serial ports, and interrupt system to continue
functioning. The Power-down mode saves the RAM
contents but freezes the oscillator, causing all other chip
functions to be inoperative.The Power-down mode can be
terminated by an external reset, by the seconds interrupt
and by any one of the two external interrupts;
see Section 15.3.
The device also functions as an arithmetic processor
having facilities for both binary and BCD arithmetic as well
as bit-handling capabilities. The instruction set of the
P8xC557E8 is the same as the 80C51 and consists of over
100 instructions: 49 one-byte, 45 two-byte, and
17 three-byte. With a 16 MHz system clock, 58% of the
instructions are executed in 0.75
μ
s and 40% in 1.5
μ
s.
Multiply and divide instructions require 3
μ
s.
