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.
