		Overview The CP-320 is a high-speed 8051 card with an assortment of interface options. A unique feature of the board is its optional IRDA ( infrared ) data link which operates at speeds of up to 115.2K Baud. In addition, the CP-320 supports a variety of PC interfaces. These include a port for high-speed communications which connects to a PC bidirectional parallel port, an RS-232C buffered serial port, and a bidirectional PC/AT compatible keyboard interface. Finally, the card has an RS-485 interface for multipoint data transmission. 80C320 Microcontroller The Microcontroller used on the CP-320 is the 80C320, which is an enhanced family derivative. It is pin-compatible with the 80C32, but offers the following improvements: optimized instruction execution, up to 33 MHz clock speed, two full-duplex serial ports, dual data pointers, power-fail reset, watchdog timer, 13 interrupt sources, and enhanced STOP and IDLE operation. Board Features The board measures 4.5 by 6.5 inches. Other board features include either 32K or 64K bytes of EPROM, 32K bytes of battery-backed SRAM, 82C55 PIO, and DS1233 processor supervisory chip. In addition to the PC interface connectors, a number of header connectors bring out various board resources. Ports 1 and 3 of the 80C320 are brought out on a 2 by 10 header connector, while Ports A, B, and C of the 82C55 come out on a 2 by 20 pin header. A 2 by 20 connector on the board is available for expansion as it brings out data, address, and control lines. The expansion connector can be used to tie in custom user circuitry. It also serves as a connection point for the AC-332 and DIGI-DAC optional analog daughterboards.
