EP610LI-20 is listed in the Programmable Logic Device Pld range at ChipApex. The manufacturer field lists Rochester Electronics, LLC. Its product description is OT PLD, 22NS, CMOS, PQCC28. Review the specifications below when checking this part for your BOM.
The EP610LI-20 is a high-performance Embedded Programmable Logic Device (EPLD) manufactured by Rochester Electronics, LLC. It features 16 macrocells and is housed in a 28-pin LDCC plastic package. The device operates within a voltage range of 4.75V to 5.25V and supports a maximum propagation delay of 22ns. This component is designed to provide reliable logic functionality for embedded applications requiring low power consumption and high speed.
Verify the specific suffix 'LI-20' against original OEM datasheets to ensure compatibility with required speed grades and package types. Confirm that the 28-pin LDCC form factor matches your PCB footprint requirements. Request manufacturer certification or traceability documentation to validate authenticity, as this part may be sourced through authorized lifecycle distributors rather than direct OEM channels.
Select this component when replacing legacy PLD/EPLD designs requiring 16 macrocells. Ensure the system voltage aligns with the 4.75V-5.25V operating range. Consider the 22ns speed grade if timing constraints are critical. Verify that the LDCC-28 package is suitable for the intended assembly process and thermal environment compared to alternative pinout packages.
Rochester Electronics specializes in end-of-life semiconductor solutions, offering authorized manufacturing and distribution of obsolete parts. The EP610 series represents a line of embedded programmable logic devices originally produced by other manufacturers. Rochester ensures these components meet original specifications, providing continuity for products where the original source is no longer available.
Check for equivalent parts from the original manufacturer if available. Compare pinouts and electrical characteristics with other EP610 variants such as EP610LC-35 or EP610PI-30 to ensure functional compatibility. Verify that any substitute maintains the same 28-pin LDCC package and 16-macrocell architecture.
