		Overview The CP-320-F is a high-speed 8051 card for process control applications. It is a general purpose single board computer containing EPROM, RAM, and Flash memory. In addition, the board has a variety of control related resources, including timer/counters, serial ports, and digital I/O lines. Connectors are available to simplify connection to user circuitry. 80C320 Microcontroller The Microcontroller used on the CP-320-F is the 80C320, which is an enhanced 8051 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 48K bytes of Flash, 16K bytes of EPROM, 32K bytes of battery-backed SRAM, 82C55 PIO, and DS1233 processor supervisory chip. 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 for connection to custom user circuitry. It also serves as a connection point for the AC-332 and DIGI-DAC optional analog daughterboards. Power Supply Options Board power can be generated using either a voltage regulator or DC-DC converter. The voltage regulator is the least expensive approach, and uses a +9 Volt DC unregulated wall adapter as the power source. Another power option uses an on-board DC-DC converter. In this case, the user must provide a 24 to 36 Volt DC source.
