SINGLE-CHIP 4-BIT CMOS MICROCOMPUTER  
2006.12.22  
DESCRIPTION  
Interrupt ........................................................................ 4 sources  
Key-on wakeup function pins ..................................................... 9  
LCD control circuit  
The 4552 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.  
Segment output ........................................................................ 28  
Common output .......................................................................... 4  
Voltage drop detection circuit (only H version)  
Reset occurrence .................................... Typ. 1.8 V (Ta = 25 °C)  
Reset release .......................................... Typ. 1.9 V (Ta = 25 °C)  
Watchdog timer  
The various microcomputers in the 4552 Group include variations  
of the built-in memory size as shown in the table below.  
Clock generating circuit  
FEATURES  
Minimum instruction execution time  
Built-in clock  
(on-chip oscillator)  
Mask ROM version .............................................................. 0.5 µs  
(at 6 MHz oscillation frequency, in high-speed through-mode)  
One Time PROM version................................................... 0.68 µs  
(at 4.4 MHz oscillation frequency, in high-speed through-mode)  
Supply voltage  
Main clock  
(ceramic resonator/RC oscillation)  
Sub-clock  
(quartz-crystal oscillation)  
LED drive directly enabled (port D)  
Mask ROM version ...................................................... 1.8 to 5.5 V  
One Time PROM version............................................. 1.8 to 3.6 V  
(It depends on operation source clock, oscillation frequency and op-  
eration mode)  
APPLICATION  
Remote control transmitter  
Timers  
Timer 1...................................... 8-bit timer with a reload register  
Timer 2................................. 8-bit timer with two reload registers  
Timer 3.............................. 16-bit timer (fixed dividing frequency)
