1 / 59 page  COP8FG Family 8-Bit CMOS ROM Based and OTP Microcontrollers with 8k to 32k Memory, Two Comparators and USART General Description Note: COP8FG devices are 15 MHz versions of the COP8SG devices. The COP8FGx5 Family ROM based microcontrollers are highly integrated COP8™ Feature 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. COP8FGx7 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), 4.5V to 5.5V operation, program code se- curity, and 28/40/44 pin packages.
