E0C6281

4-bit Single Chip Microcomputer

● Core CPU Architecture

● SVD Circuit/Comparator

● Melody Circuit

■ DESCRIPTION

The E0C6281 is an advanced single-chip CMOS 4-bit microcomputer consisting of the E0C6200 CMOS 4-bit

core CPU. It also contains the ROM, RAM, LCD driver, time base counter and melody generation circuit.

The E0C6281 provides an excellent solution for low-power consumption systems with clock functions.

2 bits (for melody output): MO, MO (also used as the external CR

connecting terminal for envelope)

1 bit (for lamp output)

1 bit (for clock output: frequency can be selected from 256Hz

through 32kHz by mask option)

● I/O port ..................................................4 bits

● LCD driver .............................................26 segments × 3 commons, 1/3 duty or 4 commons, 1/4 duty

● Built-in stopwatch timer
