EPC8QI100

Configuration PROMs For FPGAs Overview

The Altera EPC8QI100 is an Enhanced Configuration PROM designed for FPGA configuration. It provides 8 Mbit storage capacity and operates within a supply voltage range of 3V to 3.6V. The device supports system-in-programmable functionality, allowing for in-system updates. It is housed in a 100-PQFP (20x14) surface-mount package with 100 pins. The component functions across an industrial temperature range of -40°C to 85°C. This memory device serves as non-volatile storage for loading configuration data into compatible Altera FPGAs upon power-up.

Configuration PROMs For FPGAs Feature Summary

• System-in-programmable capability enables configuration updates without removing the device from the circuit board.
• Non-volatile flash memory architecture retains FPGA configuration data during power-off periods.
• Designed specifically for high-density FPGA initialization and configuration management.

Configuration PROMs For FPGAs Applications

• Configuration of Altera Cyclone and Stratix series FPGAs
• Industrial control systems requiring reliable FPGA boot sequences
• Telecommunications infrastructure equipment

Configuration PROMs For FPGAs Procurement Notes

Verify the specific suffix and package variant against the official datasheet, as the EPC8 family includes multiple pin-compatible options. Confirm that the target FPGA design matches the supported configuration protocols for this generation of devices. Check for end-of-life status or obsolescence notices, as this product line has been discontinued by the manufacturer. Ensure compatibility with existing programming tools and software versions used for flashing configuration data.

Configuration PROMs For FPGAs Selection Notes

Select this component when an 8 Mbit configuration capacity is required for legacy Altera FPGA designs. Consider the 100-pin PQFP package constraints for PCB layout and thermal management. Evaluate if newer EPCS or EPCQ series devices offer better performance or availability for new designs, as this part belongs to an older generation. Verify that the operating voltage and temperature range meet the specific environmental requirements of the target application.

Configuration PROMs For FPGAs Part Context

The EPC8QI100 belongs to the Enhanced Configuration (EPC) device family produced by Altera, now part of Intel. These devices were widely used to store configuration bitstreams for various FPGA families. The EPC8 series specifically offered higher density than earlier EPC4 devices, supporting more complex logic designs. This component represents a standard solution for non-volatile configuration in mid-range FPGA applications prior to the widespread adoption of serial Flash alternatives.

Configuration PROMs For FPGAs Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The EPC8 family is listed as discontinued. Designers should consult official migration guides for transitioning to current Intel FPGA configuration memory solutions.
