COP8SG Family  
8-Bit CMOS ROM Based and OTP Microcontrollers with  
8k to 32k Memory, Two Comparators and USART  
Erasable windowed versions (Q3) are available for use with  
a range of COP8 software and hardware development tools.  
General Description  
The COP8SG Family ROM and OTP based microcontrollers  
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,  
™
are highly integrated COP8 Feature core devices with 8k  
to 32k memory and advanced features including Analog  
comparators, and zero external components. These single-  
chip CMOS devices are suited for more complex applica-  
tions requiring a full featured controller with larger memory,  
™
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-  
low EMI, two comparators, and  
a full-duplex USART.  
™
lectable options (WATCHDOG , 4 clock/oscillator modes,  
COP8SGx7 devices are 100% form-fit-function compatible  
OTP (One Time Programmable) versions for use in produc-  
tion or development of the COP8SGx5 ROM.
