Overview
The FPGA104 is a building platform that supports up to four daughter cards. Each daughter card location supports interfaces ith up to 28 I/O signals. Each daughter card location is symmetrical. Daughter cards can encompass one or more daughter card locations for greater I/O. For example, the FPDB-DEV uses all four daughter card locations and has access to 112 I/O signals.
The FPGA104 is PC/104 compliant and is interfaced to the full PC/104 bus signals including memory and I/O mapped signals.
The on-board FPGA is configured via the on-board EEPROM, ISA/PCI bus, or the JTAG port. The configuration EEPROM can be programmed, independently of the FPGA, over the PC/104 bus or via the ISP port.
The FPGA104 is based on the Altera's Cyclone FPGA family: 4K, 12K or 20K logic element parts. Altera's free Quartus-II basic FPGA design software can be used by the end-user to define the circuit/system functions to be implemented in the on-board FPGA.
The FPGA104 has an on-board real-time counter/clock with SuperCap backup, and a unique read-only 64-bit serial number ROM.
Included on the FPGA104 and are the connectors and physical layer circuits for 10/100 Ethernet and optionally a 10/100/1000 GIGJACK port, and an I2C/SMBus. Also included are a 50 MHz oscillator, and an SMB connector for an external reference frequency source.
The FPGA104 is powered from the ISA/PCI bus, or external 6V DC to 18V DC supply. Temperature range is 0°C to 85°C.
