COP888xG/CS Family
8-Bit CMOS ROM Based Microcontrollers with 4k to 24k
Memory, Comparators and USART
General Description
Note: COP8SG devices are form-fit-function compatible su-
persets of the COP888xG/CL/CS Family devices, and are
replacements for these in new designs, and design up-
grades with minimum effort.
The COP888xG ROM based microcontrollers are highly inte-
grated COP8Feature core devices with larger memory (4k
to 24k) and advanced features including two Analog com-
parators. These single-chip CMOS devices are suited for
more complex applications requiring a full featured controller
with a range of memory sizes, low EMI (except EG), com-
parators, and a full-duplex USART. Pin and software com-
patible (different VCC range) 8k toor 32k OTP (One Time
Programmable) versions are available (COP8SGx7 Family).
Erasable windowed versions are available for use with a
range of software and hardware development tools.
Family features include an 8-bit memory mapped architec-
ture, 10 MHz CKI with 1µs instruction cycle, three multi-
function 16-bit timer/counters, full-duplex USART,
MICROWIRE/PLUSserial I/O, two Analog comparators,
two power saving HALT/IDLE modes, idle timer, MIWU, high
current outputs, software selectable I/O options, WATCH-
DOGtimer and Clock Monitor, low EMI 2.5V to 5.5V opera-
tion, and 28/40/44 pin packages.
