The S3C8465/C8469 single-chip 8-bit microcontroller is designed for useful 10-bit resolution A/D converter, UART, SIO, ZCD extended PWM application field. Its powerful SAM87 CPU architecture includes. The internal register file is logically expanded to increase the on-chip register space. The S3C8465/C8469 has 16/32K bytes of on-chip program ROM. A sophisticated bus interface enables access to external memory and other peripherals when you use the chip in ROM-less mode. Following Samsung's modular design approach, the following peripherals are integrated with the SAM87 core: -- Large number of programmable I/O ports (total 56 pins) -- One asynchronous UART module -- One synchronous SIO module
