The COP8SG family is a series of highly integrated 8-bit CMOS ROM and OTP microcontrollers with 8k to 32k memory and advanced features including analog comparators and zero external components. These single-chip CMOS devices are suitable for more complex applications requiring a full-featured controller with larger memory, low EMI, two comparators, and a full-duplex USART.
The COP8SG family are 8‑bit CMOS microcontrollers offering 8 kB to 32 kB of ROM or OTP memory, two analog comparators, a full‑duplex USART, three 16‑bit timers with PWM, and low‑EMI design. They operate from 2.7 V to 5.5 V and support clock frequencies up to 15 MHz with a 0.67 µs instruction cycle.
The datasheet provides detailed pin‑out diagrams for 28‑, 40‑ and 44‑pin packages, electrical characteristics, ordering information, and packaging options. It also includes a life‑support policy disclaimer and contact information for National Semiconductor support.
