S3C72C8 Overview
With an up-to-96-dot LCD direct drive capability flexible 16-bit timer/counter, and 4-chanel parator, the S3C72C8 offers an excellent design solution for a low CDP and a card reader. Up to 28 pins of the 44-pin QFP or up to 26 pins of the 42-pin SDIP package can be dedicated to I/O. Eight vectored interrupts provide fast response to internal and external events.
