PALCE22V10H-7PC/5

Programmable Logic Device Pld Overview

The PALCE22V10H-7PC/5 is an Electrically Erasable Programmable Logic Device (EE PLD) manufactured by Lattice Semiconductor Corporation. It belongs to the GAL22V10 family and features a PAL-type architecture with 10 macrocells. The device operates at a maximum propagation delay of 7 ns, supporting a maximum clock frequency of approximately 142 MHz. It utilizes a 24-pin Plastic Dual In-line Package (PDIP). Key electrical specifications include a supply voltage range of 4.5 V to 5.5 V and a typical operating current of 90 mA. The component is classified as obsolete.

Programmable Logic Device Pld Feature Summary

• PAL-type EE PLD architecture with 10 macrocells
• High-speed performance with 7 ns maximum propagation delay
• 24-pin PDIP package for through-hole mounting
• Single 5 V power supply operation

Programmable Logic Device Pld Applications

• Replacement for legacy PAL devices in existing designs
• Complex glue logic implementation
• Address decoding and bus arbitration
• State machine control logic

Programmable Logic Device Pld Procurement Notes

This component is officially discontinued and no longer in production. Verification of authenticity is critical due to potential availability from third-party sources or surplus markets. Buyers should confirm the specific suffix '/5' indicates the commercial temperature grade and package variant. Ensure compatibility with existing PCB footprints and programming equipment before procurement.

Programmable Logic Device Pld Selection Notes

Select this part when replacing obsolete PALs requiring 22 inputs and 10 outputs with registered outputs. The 7 ns speed grade offers higher performance than the standard 25 ns variants. Verify that the PDIP-24 package fits the target assembly constraints. Consider the GAL22V10D series for surface-mount alternatives if design flexibility allows package changes.

Programmable Logic Device Pld Part Context

The PALCE22V10H-7PC/5 is part of the Lattice GAL22V10 family, which bridges the gap between fixed-function PALs and complex FPGAs. It provides non-volatile programmability with electrically erasable memory. The 'H' suffix typically denotes high-speed performance, while '/5' specifies the commercial temperature range and PDIP package. This family was widely used in industrial and consumer electronics before being superseded by more dense programmable logic solutions.

Programmable Logic Device Pld Replacement Considerations

Direct pin-to-pin replacements are limited due to the obsolete status. Potential substitutes include other GAL22V10 variants with different speed grades or package types, such as GAL22V10D-25LJ for surface mount applications. Cross-reference with similar EE PLDs from other manufacturers may require schematic verification for pinout and electrical compatibility.
