80C51 8-bit microcontroller – 12 clock operation
16K/512 OTP/RAM, 8 channel 10-bit A/D, I
capture/compare, high I/O
DESCRIPTION
The P87C554 Single-Chip 8-Bit Microcontroller is manufactured in
an advanced CMOS process and is a derivative of the 80C51
microcontroller family. The 87C554 has the same instruction set as
the 80C51.
The 87C554 contains a 16k
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, four-priority-level, nested interrupt structure, an 8-input
ADC, a dual DAC pulse width modulated interface, two serial
interfaces (UART and I
oscillator and timing circuits. For systems that require extra
capability, the P87C554 can be expanded using standard TTL
compatible memories and logic.
In addition, the P87C554 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. Optionally, the ADC can be
operated in Idle mode. 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 plus 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 crystal,
58% of the instructions are executed in 0.75 s and 40% in 1.5 s.
Multiply and divide instructions require 3 s.
