The COP8FGx5 family is a highly integrated COP8 series ROM microcontroller 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 applications requiring a full-featured controller with larger memory, low EMI, two comparators, and a full-duplex USART. COP8FGx7 devices 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 architecture, 15 MHz CKI with 0.67 µs instruction cycle, 14 interrupts, three multi-function 16-bit timer/counters with PWM, full-duplex USART, MICROWIRE/PLUS™, two analog comparators, two power saving HALT/IDLE modes, MIWU, idle timer, on-chip R/C oscillator, high current outputs, user-selectable options (WATCHDOG™, 4 clock/oscillator modes, power-on-reset), 4.5V to 5.5V operation, program code security, and 28/40/44 pin packages.
This document describes the COP8FGx5 and COP8FGx7 families of 8-bit CMOS microcontrollers from National Semiconductor. These devices feature a modified Harvard architecture with up to 32k bytes of ROM or OTP EPROM and are designed for complex applications requiring low EMI, two analog comparators, and a full-duplex USART.
