EP22V10PC-25

Programmable Logic Device Pld Overview

The Altera EP22V10PC-25 is an Electrically Erasable Programmable Logic Device (EEPLD) based on PAL architecture. It features a CMOS construction housed in a 24-pin Plastic Dual In-line Package (PDIP). The device provides 12 dedicated inputs and 10 I/O lines, supporting up to 22 input signals with 10 registered outputs via macrocells. Operating at a maximum clock frequency of 35.7 MHz, it has a propagation delay of 25 ns. The component requires a 5 V power supply and functions within a commercial temperature range of 0 °C to 70 °C.

Programmable Logic Device Pld Procurement Notes

Verify the manufacturer origin carefully, as this component was originally produced by Lattice Semiconductor before its acquisition by Vantis Corporation. Confirm the specific suffix 'PC' indicates the PDIP package and '25' denotes the speed grade. Check RoHS compliance status, as original versions may not meet current environmental standards. Ensure the source provides valid traceability for legacy programmable logic components.

Programmable Logic Device Pld Selection Notes

Select this part when a simple PAL structure with registered outputs is required for low-pin-count applications. Compare against the EP22V10 variant if surface mount packaging is preferred. Verify that the 5 V voltage level matches the system logic requirements. Consider pin-compatible alternatives from the same family if higher speed grades or different package types are needed for the design.

Programmable Logic Device Pld Part Context

This device belongs to the PALCE22V10 series of electrically erasable PLDs. Originally manufactured by Lattice Semiconductor, production rights transferred to Vantis Corporation following corporate acquisitions. The EP22V10PC-25 represents the commercial temperature version in a through-hole DIP package, serving as a direct drop-in replacement for older non-erasable PAL devices in existing hardware designs.

Programmable Logic Device Pld Replacement Considerations

Direct pin-compatible replacements include other speed grades within the PALCE22V10 family, such as the -15 or -10 variants, provided timing constraints allow. Cross-brand equivalents from Microchip or Atmel may require schematic review due to potential differences in macrocell functionality or pin assignments.
