ORCA Series 2 FPGAs
Description (continued)
The FPGA’s functionality is determined by internal configuration RAM. The FPGA’s internal initialization/configura-
tion circuitry loads the configuration data at powerup or under system control. The RAM is loaded by using one of
several configuration modes. The configuration data resides externally in an EEPROM, EPROM, or ROM on the
circuit board, or any other storage media. Serial ROMs provide a simple, low pin count method for configuring
FPGAs, while the peripheral and JTAG configuration modes allow for easy, in-system programming (ISP).
