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.
