• Multiple configuration clock sources supported (internal oscillator and external clock input pin)
• External clock source with frequencies up to 100 MHz
• Internal oscillator defaults to 10 MHz and you can program the internal oscillator for higher frequen‐
cies of 33, 50, and 66 MHz
• Clock synthesis supported using user programmable divide counter
• Available in the 100-pin plastic quad flat pack (PQFP) and the 88-pin Ultra FineLine BGA (UFBGA)
packages
• Vertical migration between all devices supported in the 100-pin PQFP package
• Supply voltage of 3.3 V (core and I/O)
• Hardware compliant with IEEE Std. 1532 in-system programmability (ISP) specification
• Supports ISP using Jam Standard Test and Programming Language (STAPL)
• Supports JTAG boundary scan
• The nINIT_CONF pin allows private JTAG instruction to start FPGA configuration
• Internal pull-up resistor on the nINIT_CONF pin always enabled
• User programmable weak internal pull-up resistors on nCS and OE pins
• Internal weak pull-up resistors on external flash interface address and control lines, bus hold on data
lines
• Standby mode with reduced power consumption
Note:
For more information about FPGA configuration schemes and advanced features, refer to the
configuration chapter in the appropriate device handbook.
Functional Description
The Altera EPC device is a single device with high speed and advanced configuration solution for high-
density FPGAs. The core of an EPC device is divided into two major blocks—a configuration controller
and a flash memory. The flash memory is used to store configuration data for systems made up of one or
more than one Altera FPGAs. Unused portions of the flash memory can be used to store processor code
or data that can be accessed using the external flash interface after the FPGA configuration is complete.
