8-BIT MICROCOMPUTER UNIT

HARDWARE FEATURES

DESCRIPTION

32 TTL/CMOS COMPATIBLE I/O LINES

24 BIDIRECTIONAL (8 lines are LED compati-

ble)

8 INPUT-ONLY

3776 BYTES OF USER ROM

112 BYTES OF RAM

The EF6805U3 Microcomputer Unit (MCU) is a

member of the 6805 Family of low-cost single-chip

Microcomputers. The 8-bit microcomputer contains

a CPU, on-chip CLOCK, ROM, RAM, I/O, and TI-

MER. It is designed for the user who needs an eco-

nomical microcomputer with the proven capabilities

of the 6800-based instruction set. A comparison of

thekey features of several members of the 6805 Fa-

mily of Microcomputers is shown at the end of this

data sheet. The following are some of the hardware

and software highlights of the EF6805U3 MCU.
