DescriptionHitachi SCA-I Series Communication DevicesThe SCA Series of devices converts parallel data to serial data, and serial data to parallel data for communication with other devices. The HD64570 and HD64572 Serial Communications Adapter (SCA-I and SCA-II, respectively) peripheral chips enable a host microprocessor to perform asynchronous, byte synchronous, or bit synchronous serial communication. The SCA-II can also perform transparent communication.Both chips have two independent full-duplex, multiprotocol serial channels that support a wide variety of communications protocols such as frame relay, HDLC, SDLCª, X.25, LAPB, LAPD, mono sync, bisync, X.21, DDCMP, asynch, etc. Both chips also include a built-in direct memory access controller (DMAC) with deep FIFOs that can execute chained-block transfers, enabling high-speed transfers of data between an SCA device and memory. Due to the on-chip DMAC, the SCA Series can support very high data rates without monopolizing the bus, even in full-duplex communication. Other on-chip features of the SCA Series include direct MPU interfaces, a bus arbiter, timers, and an interrupt controller.Highly optimized, the SCA Series of devices are used in a large number of datacommunication and networking applications such as bridges, routers, multiplexers, switches, frame relay exchanges, broad band and Internet access products, LAN/WAN interface cards, T1/E1 applications, fractional T3 applications, protocol converters, repeaters, frame relay over ATM applications, remote access LAN products, etc.
