Intel Corporation Configuration PROMs for FPGAs EPC4QI100

The EPC4QI100 is a configuration PROM designed for use with Altera FPGAs, featuring a memory size of 4,194,304 bits. It supports on-chip decompression, which effectively doubles the configuration density, and is compatible with various Altera FPGA families including ACEX, APEX, Arria, Cyclone, and Stratix series. The device operates at a supply voltage of 3.3 V and supports in-system programmability (ISP) compliant with IEEE Std. 1532. The EPC4QI100 offers multiple configuration clock sources, including an internal oscillator with programmable frequencies up to 66 MHz and an external clock input supporting frequencies up to 100 MHz. It is available in a 100-pin plastic quad flat pack (PQFP) package, allowing for vertical migration between devices. The device also features a page mode for remote and local reconfiguration, supporting up to eight configurations for the entire system. Engineers considering this product should note its capabilities for flash memory block protection and the ability to access unused portions of memory for additional processor code storage. The EPC4QI100 is suitable for applications requiring efficient configuration solutions for high-density FPGAs.
