DESCRIPTION
The 4506 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 a reload register), interrupts, and
10-bit A/D converter.
The various microcomputers in the 4506 Group include variations
of the built-in memory size as shown in the table below.
FEATURES
qMinimum instruction execution time ................................ 0.68 µs
(at 4.4 MHz oscillation frequency, in high-speed mode)
qSupply voltage .......................................................... 2.0 V to 5.5 V
(It depends on the oscillation frequency and operating mode.)
q Timers
Timer 1 ...................................... 8-bit timer with a reload register
Timer 2 ...................................... 8-bit timer with a reload register
qInterrupt ........................................................................ 4 sources
qKey-on wakeup function pins ................................................... 12
qInput/Output port ...................................................................... 14
qA/D converter .................. 10-bit successive comparison method
qWatchdog timer
qClock generating circuit (ceramic resonator/RC oscillation)
qLED drive directly enabled (port D)
APPLICATION
Electrical household appliance, consumer electronic products, of-
fice automation equipment, etc.

DEFINITION OF CLOCK AND CYCLE
q Operation source clock
The operation source clock is the source clock to operate this
product. In this product, the following clocks are used.
• External ceramic resonator
• External RC oscillation
• Clock (f(XIN)) by the external clock
• Clock (f(RING)) of the on-chip oscillator which is the internal
oscillator.
q System clock
The system clock is the basic clock for controlling this product.
The system clock is selected by the bits 2 and 3 of the clock con-
trol register MR.
q Instruction clock
The instruction clock is a signal derived by dividing the system
clock by 3. The one instruction clock cycle generates the one
machine cycle.
q Machine cycle
The machine cycle is the standard cycle required to execute the
instruction.
Table Selection of system clock

MR3 MR2
(Note 1)
0 0 f(XIN) or f(RING)
0 1 f(XIN)/2 or f(RING)/2
1 0 f(XIN)/4 or f(RING)/4
1 1 f(XIN)/8 or f(RING)/8
Operation mode
High-speed mode
Middle-speed mode
Low-speed mode
Default mode
Notes 1: The on-chip oscillator clock is f(RING), the clock by the
ceramic resonator, RC oscillation or external clock is
f(XIN).
2: The default mode is selected after system is released
from reset and is returned from RAM back-up.
