2. GENERAL DESCRIPTION
The P80C557E6/P83C557E6 (hereafter generically referred to as
P8xC557E6) single-chip 8-bit microcontroller is manufactured in an
advanced CMOS process and is a derivative of the 80C51
microcontroller family. The P8xC557E6 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
•
I
2
C-bus serial I/O port with byte oriented master and slave
functions
•
P83C557E6 — 48 Kbytes mask programmable ROM
•
P80C557E6 — ROMless version of the P83C557E6
•
Full-duplex UART compatible with the standard 80C51
•
On-chip watchdog timer
•
15 interrupt sources with 2 priority levels (2 to 6 external sources
possible)
•
Extended temperature range (–40 to +85
°C)
•
4.5 to 5.5 V supply voltage range
•
Frequency range for 80C51–family standard oscillator: 3.5 MHz to
16 MHz
The P8xC557E6 contains a non-volatile 48 Kbytes mask
programmable ROM (P83C557E6), a volatile 1536
×
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 P8xC557E6 can be expanded using standard TTL
compatible memories and logic.
In addition, the P8xC557E6 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.
