COP8SG Family
8-Bit CMOS ROM Based and OTP Microcontrollers with
8k to 32k Memory, Two Comparators and USART
General Description
The COP8SGx5 Family ROM based microcontrollers are
highly integrated COP8Feature core devices with 8k to
32k memory and advanced features including Analog com-
parators, and zero external components. These single-chip
CMOS devices are suited for more complex applications re-
quiring a full featured controller with larger memory, low EMI,
two comparators, and a full-duplex USART. COP8SGx7 de-
vices are 100% form-fit-function compatible 8k or 32k OTP
(One Time Programmable) versions for use in production or
development.
Erasable windowed versions are available for use with a
range of COP8 software and hardware development tools.
Family features include an 8-bit memory mapped architec-
ture, 15 MHz CKI with 0.67 µs instruction cycle, 14 inter-
rupts, three multi-function 16-bit timer/counters with PWM,
full duplex USART, MICROWIRE/PLUS, two analog com-
parators, two power saving HALT/IDLE modes, MIWU, idle
timer, on-chip R/C oscillator, high current outputs, user se-
lectable options (WATCHDOG, 4 clock/oscillator modes,
power-on-reset), 2.7V to 5.5V operation, program code se-
curity, and 28/40/44 pin packages.
