DESCRIPTION
The 4559 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 two 8-bit timers (each timer has one or two reload registers),
a 16-bit timer for clock count, interrupts, and oscillation circuit
switch function.
The various microcomputers in the 4559 Group include
variations of type as shown in the table below.
FEATURES
• Minimum instruction execution time..............................0.5 µs
(at 6 MHz oscillation frequency, in high-speed through-mode)
• Supply voltage .......................................................1.8 to 5.5 V
(It depends on operation source clock, 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 two reload registers and carrier wave generation circuit
Timer 3........................ 16-bit timer (fixed dividing frequency)
• Interrupt ..................................................................... 4 sources
• Key-on wakeup function pins .............................................. 17
• I/O port ................................................................................. 22
• Output port ............................................................................. 3
• LCD control circuit
Segment output ..................................................................... 32
Common output ...................................................................... 4
• Voltage drop detection circuit
Reset occurrence..................................Typ. 1.7 V (Ta = 25 °C)
Reset release ........................................Typ. 1.8 V (Ta = 25 °C)
Skip occurrence ...................................Typ. 2.0 V (Ta = 25 °C)
• Power-on reset circuit
• Watchdog timer
• Clock generating circuit
Built-in clock (on-chip oscillator)
Main clock (ceramic resonator/RC oscillation)
Sub-clock (quartz-crystal oscillation)
• LED drive directly enabled (port D)
