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
COP8SER7 devices are pin and software compatible (differ-
ent V
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-
including
EERAM.
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.
