HD64570F - Brand New Renesas Electronics America Interface - Specialized
-
Overview
The HD64570 serial communications adaptor (SCA) converts parallel data to serial data for communication with other devices. Its two independent, full- duplex transceivers support both synchronous (bit-synchronous or byte- synchronous) and asynchronous communication. Extensive protocol functions are provided.
The SCA chip provides FIFO transmit and receive buffers with 32 stages each and a four-channel direct memory access controller (DMAC) with chained-block transfer facilities, enabling high speed transfer of data between SCA and memory. A built-in bus arbiter and 16-bit bus interface support high- performance system designs.Features
• Data transfer rate: 50 bits/s to 7.1 Mbits/s (f = 10 MHz),
50 bits/s to 12 Mbits/s (f = 16.7 MHz)
50 bits/s to 5.7 Mbits/s (f = 8 MHz)
• Protocol support
Asynchronous (ASYNC): 5 to 8 bits + parity
Byte synchronous (COP): bisync, X.21, DDCMP, etc.
_ Bit synchronous (BOP): frame relay, HDLC, SDLC, X.25 link level (LAPB), LAPD etc.
• Highly efficient data transfer: two 32-byte FIFOs (transmit/receive) per channel
• Error detection: parity (asynchronous)
CRC-16, CRC-CCITT (byte- and bit-synchronous)
