SINGLE-CHIP 4-BIT CMOS MICROCOMPUTER  
2005.06.15  
DESCRIPTION  
ꢀInterrupt ........................................................................ 8 sources  
ꢀKey-on wakeup function pins ................................................... 10  
ꢀSerial interface ............................................................. 8 bits ꢀ 1  
ꢀ A/D converter .......... 10-bit successive comparison method, 8ch  
ꢀVoltage drop detection circuit  
The 4519 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  
serial interface, four 8-bit timers (each timer has one or two reload  
registers), a 10-bit A/D converter, interrupts, and oscillation circuit  
switch function.  
Reset occurrence .................................... Typ. 3.5 V (Ta = 25 °C)  
Reset release .......................................... Typ. 3.7 V (Ta = 25 °C)  
ꢀWatchdog timer  
The various microcomputers in the 4519 Group include variations  
of the built-in memory size as shown in the table below.  
ꢀClock generating circuit  
(ceramic resonator/RC oscillation/quartz-crystal oscillation/on-  
chip oscillator)  
FEATURES  
ꢀMinimum instruction execution time .................................. 0.5 µs  
(at 6 MHz oscillation frequency, in XIN through-mode)  
ꢀSupply voltage  
ꢀLED drive directly enabled (port D)  
APPLICATION  
Mask ROM version ...................................................... 1.8 to 5.5 V  
One Time PROM version............................................. 2.5 to 5.5 V  
(It depends on operation source clock, oscillation frequency and op-  
eration mode)  
Electrical household appliance, consumer electronic products, of-  
fice automation equipment, etc.  
ꢀTimers  
Timer 1...................................... 8-bit timer with a reload register  
Timer 2...................................... 8-bit timer with a reload register  
Timer 3...................................... 8-bit timer with a reload register  
Timer 3................................. 8-bit timer with two reload registers
