DESCRIPTION
The 4571 Group is a 4-bit single-chip microcomputer designed
with CMOS technology. Its CPU is that of the 4500 series using a
simple, high-speed instruction set. The computer is equipped
with three 8-bit timers (each timer has one or two reload
registers), interrupts, and voltage drop detection circuit.
The various microcomputers in the 4571 Group include
variations of the built-in memory size as shown in the table
below.
FEATURES
Minimum instruction execution time..............................0.5
s
(at 6 MHz oscillation frequency, in through-mode)
Supply voltage .......................................................1.8 to 5.5 V
(It depends on oscillation frequency and operation mode)
Timers
Timer 1..................................8-bit timer with a reload register
and carrier wave output auto-control function
Timer 2..................................8-bit timer with a reload register
Timer 3..................... 8-bit timer with two reload registers and
carrier wave generation circuit
Interrupt ..................................................................... 6 sources
Key-on wakeup function pins .............................................. 12
I/O port ................................................................................. 17
Output port ............................................................................. 1
Input port ................................................................................ 1
Voltage drop detection circuit
Reset occurrence................................ Typ. 1.65 V (Ta = 25
°C)
Reset release ...................................... Typ. 1.75 V (Ta = 25
°C)
Interrupt occurrence........................... Typ. 1.85 V (Ta = 25
°C)
Watchdog timer
Power-on reset circuit
Clock generating circuit (ceramic resonator)
