		Overview The CP-332 is a single board computer based on the 68332 microcontroller. A number of features distinguish the CP-332 from other 68332 based cards. These include a processor supervisory circuit, sockets for all board I.C.'s, 88C681 DUART, support for high density memory devices, and optional analog and motion control daughterboards. The CP-332 measures 5.5 by 8.5 inches. Resources on the card can be considered as five separate subsections: 68332 microcontroller, memory section, 68881 FPU ( optional ), processor supervisory circuit, 88C681 DUART, and daughterboard expansion connector. Memory The board supports up to 768K bytes of EPROM, RAM, and EEPROM in six-32 pin JEDEC standard memory sockets. Digital and Serial I/O The 88C681 provides one 8-bit output port and one 7-bit input port. Additional input/output port lines are available on the 68332, depending on resource usage. Three UARTs are available on the board. Two of these are RS-232C buffered and brought out on header connectors. Optional Daughterboards Currently, two optional daughterboards are available. The AC-332 analog daughterboard provides 4 channels of 12-bit A/D conversion and 2 channels of 12-bit D/A conversion. Also, the DIGI-DAC motion control daughterboard provides 6 channels of 12-bit D/A conversion and 24 digital I/O lines. Connectors All CPU lines are brought out on four separate 2 by 20 pin header connectors. The CPU's UART is RS-232C buffered and brought out on a 2 by 5 pin header. Serial Port A of the 88C681 is RS-232 buffered and brought out on a 2 by 5 header. The two parallel ports of the 88C681 and its serial port B lines are brought out ( unbuffered ) to a 2 by 10 pin header. A 2 by 20 pin header is available for adding custom user circuitry or as a connection point for the optional daughterboards. Optional 68881 FPU A socket is provided for the 68881 FPU. Note that this socket is unpopulated as the board is shipped from the factory. Power Requirements The CP-332 requires +5 Volts ( regulated ) at 300 ma ( maximum ).
