E0C621A  
4-bit Single Chip Microcomputer  
● Core CPU Architecture  
● 32kHz/455kHz Twin Clock Operation  
● SVD Circuit/Analog Comparator  
● Watchdog Timer  
■ DESCRIPTION  
The E0C621A is a CMOS 4-bit microcomputer using an E0C6200A as its core processor. It contains ROM,  
RAM, LCD driver circuit, remote-control carrier output circuit, time base counter, analog comparator, watchdog  
timer and other functions on a single chip. The E0C621A provides an excellent solution for low-power system  
applications such as an infrared remote controller with clock function.  
One time PROM version is available.  
■ FEATURES  
● CMOS LSI 4-bit parallel processing  
● Twin clock .............................................32.768kHz (Typ.) Crystal  
455kHz (Typ.)  
CR or Ceramic oscillation circuit  
(selectable by mask option)  
● Instruction set........................................100 instructions  
● Instruction cycle time ............................32kHz clock mode : 153µsec, 214µsec or 366µsec  
455kHz clock mode : 11µsec, 15µsec or 26µsec  
● ROM capacity .......................................4,096 × 12 bits  
● RAM capacity ........................................208 × 4 bits  
● Input port ...............................................8 bits (pull-up resistors are available by mask option)  
● Output port ............................................9 bits (clock, buzzer output is available by mask option)  
● I/O port ..................................................4 bits  
● Remote control carrier (REM)...............1 bit (hardware timer or software timer is selectable by software)  
● LCD driver .............................................32 segments × 3 commons or 32 segments × 4 commons  
(1/3 or 1/4 duty is selectable by mask option)  
● Built-in LCD power supplies..................Voltage regulator, voltage doubler and voltage tripler  
● Built-in SVD circuit ................................2.3V ± 0.1V (supply voltage detector) Criteria voltage  
● Built-in amplifier ....................................Operational amplifier for MOS input analog comparator  
● Built-in watchdog timer (Mask option)  
● Interrupts ...............................................External : Input interrupt  
Internal : Timer interrupt (32Hz, 8Hz, 2Hz) 1 line (3ch.)  
REM interrupt 1 line  
2 lines  
● Supply voltage ......................................3.0V (2.2V to 3.5V)  
● Current consumption ............................HALT mode (32.768kHz)  
: 2µA (Typ.)  
OPERATING mode (455kHz) : 130µA (Typ.)  
● Package ................................................QFP5-80pin (plastic), QFP14-80pin (plastic)  
Die form
