• High-speed operation with 3.0ns maximum propagation delay
• Single 3.3V power supply compatibility (2.7V–3.6V range)
• In-system programmability via JTAG interface

Programmable Logic Device Pld Applications

• Address decoding and bus interfacing in embedded systems
• Replacement for legacy GALs and PALs in existing designs
• Protocol conversion between different logic families
• State machine implementation in industrial control units

Programmable Logic Device Pld Procurement Notes

Verify the specific suffix code (e.g., LC-30) against the manufacturer's current datasheet to confirm package type and temperature grade. Rochester Electronics products are often last-time-buy or sustainment items; confirm availability status directly with the supplier. Ensure the JTAG programming requirements match your existing test infrastructure before procurement.

Programmable Logic Device Pld Selection Notes

Select the EP910LC-30 when design requirements exceed the capacity of simple logic gates but do not justify the complexity of an FPGA. Compare pin counts and macrocell density against alternative CPLDs from the same era. Verify that the 3.3V operating voltage aligns with the rest of the system's logic levels to avoid level-shifting requirements.

Programmable Logic Device Pld Part Context

Rochester Electronics specializes in sustaining obsolete semiconductor products. The EP910 series is part of the original Lattice Semiconductor EP900 family. Rochester provides continued production and testing for these devices, ensuring supply continuity for long-life applications where original manufacturers have discontinued support.

Programmable Logic Device Pld Replacement Considerations

Direct functional equivalents include other EP910 variants with different speed grades or packages. Cross-reference with original Lattice Semiconductor EP910 datasheets for pinout and electrical parameter compatibility. Ensure any substitute maintains the same I/O voltage levels and programming interface.
