80C51 8-bit microcontroller – 6-clock operation
16K/512 OTP/ROMless, 7 channel 10 bit A/D, I
capture/compare, high I/O, 64L LQFP
8DESCRIPTION
This data sheet describes the 6 clock version of the 8xC554. This
device is only available in 64L LQFP. The 8xC554 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. Three versions of the
derivative exist:
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 7-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 8xC554 can be expanded using standard TTL
compatible memories and logic.
In addition, the 8xC554 has two software selectable modes of power
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 an 8-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.
