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.

● 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)
