COP8SE Family

8-Bit CMOS ROM Based and OTP Microcontrollers with

4k Memory and 128 Bytes EERAM

General Description

The COP8SEx5 Family ROM based microcontrollers are

highly integrated COP8™ Feature core devices with 4k

memory

and

advanced

features

including

EERAM.

COP8SER7 devices are pin and software compatible (differ-

ent V

CC range), 32k OTP (One Time Programmable) ver-

sions for engineering development use with a range of

COP8 software and hardware development tools.

Family features include an 8-bit memory mapped architec-

ture, 10 MHz CKI with 1µs instruction cycle, 128 bytes of EE-

RAM, one multi-function 16-bit timer/counter, idle timer with

MIWU, MICROWIRE/PLUS™, serial I/O, crystal or R/C oscil-

lator, two power saving HALT/IDLE modes, Schmitt trigger

inputs, software selectable I/O options, WATCHDOG™ timer

and Clock Monitor, Low EMI 2.7V to 5.5V operation, and

16/20 pin packages.
