COP8SG Family
8-Bit CMOS ROM Based and OTP Microcontrollers with
8k to 32k Memory, Two Comparators and USART
General Description
The COP8SG Family ROM and OTP based microcontrollers
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,
low EMI, two comparators, and a full-duplex USART.
COP8SGx7 devices are 100% form-fit-function compatible
OTP (One Time Programmable) versions for use in produc-
tion or development of the COP8SGx5 ROM.
Erasable windowed versions (Q3) 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.
