Configuration PROMs For FPGAs Procurement Notes

Verify the specific suffix PC8 corresponds to the 8-pin PDIP package variant when sourcing. Confirm operational voltage requirements align with your system design, as this device supports both 5.0-V and 3.3-V interfaces. Ensure compatibility with legacy Altera device families such as ACEX, APEX, FLEX, and Mercury, as newer FPGA architectures may require different configuration controllers. Check RoHS compliance status if required by your manufacturing standards, as older stock may not meet current environmental regulations.

Configuration PROMs For FPGAs Selection Notes

Select the EPC1064PC8 when configuring smaller capacity Altera CPLDs or early FPGA families that utilize serial configuration protocols. This part is appropriate for systems requiring a cost-effective, through-hole mounted configuration memory solution. Consider the 64K-bit density limit; larger devices like Stratix or Cyclone series typically require Enhanced Configuration Devices (EPC4, EPC8, or EPC16) due to higher data volume requirements. Evaluate the 4 MHz clock speed against your system's timing constraints for reliable data transfer during the configuration phase.

Configuration PROMs For FPGAs Part Context

The EPC1064 belongs to the original serial device family introduced by Altera for configuring its earlier generation programmable logic products. Unlike the later Enhanced Configuration Devices (EPC4/8/16) which offer on-chip decompression and parallel interfaces, this series relies on a straightforward serial protocol. It serves as a foundational component for legacy designs involving ACEX, APEX, and FLEX families, providing non-volatile storage for device bitstreams in embedded systems.
