2. GENERAL DESCRIPTION
The P80CE558/P83CE558/P89CE558 (hereafter generically
referred to as P8xCE558) single-chip 8-bit microcontroller is
manufactured in an advanced CMOS process and is a derivative of
the 80C51 microcontroller family. The P8xCE558 has the same
instruction set as the 80C51. Three versions of the derivative exist:
•
•
•
P83CE558 — 32 Kbytes mask programmable ROM
P80CE558 — ROMless version of the P83CE558
P89CE558 — 32 Kbytes FEEPROM (Flash-EEPROM)
The P8xCE558 contains a non-volatile 32 Kbytes mask
programmable ROM (P83CE558) or electrically erasable FEEPROM
respectively (P89CE558), a volatile 1024
×
8 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 DAC pulse width modulated interface, two serial
interfaces (UART and I
2
C-bus), a “watchdog” timer, an on-chip
oscillator and timing circuits. For systems that require extra
capability the P8xCE558 can be expanded using standard TTL
compatible memories and logic.
In addition, the P8xCE558 has two software selectable modes of
power reduction — 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 device also functions as an arithmetic processor having
facilities for both binary and BCD arithmetic as well as bit-handling
capabilities. The instruction set 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
µs
and 40% in
1.5
µs.
Multiply and divide instructions require 3
µs.
