PALCE22V10-5PC

Programmable Logic Device Pld Overview

The PALCE22V10-5PC is a CMOS Flash-erasable programmable logic device (PLD) from Cypress Semiconductor. It utilizes a second-generation PAL architecture with a sum-of-products structure and programmable macrocells. The device features 22 inputs and 10 outputs, organized as 12 dedicated inputs and 10 I/O lines. It supports variable product terms ranging from 8 to 16 per macrocell. The '5' suffix indicates a 5 ns propagation delay specification, enabling high-speed state machine operations up to 181 MHz in commercial versions. It is housed in a 24-pin PDIP package.

Programmable Logic Device Pld Feature Summary

• CMOS Flash EPROM technology for electrical erasability and reprogrammability without UV exposure
• Programmable macrocells with individually selectable registered or combinatorial output modes
• Output polarity control for each macrocell
• Up to 22 input terms and 10 outputs with variable product terms (2x(8 through 16))

Programmable Logic Device Pld Applications

• High-speed state machine implementations
• Complex glue logic replacement
• Address decoding and bus arbitration
• Memory interface control logic

Programmable Logic Device Pld Procurement Notes

Verify the specific speed grade suffix matches the required timing constraints, as the '5' denotes a 5 ns performance level. Confirm the package type corresponds to the design footprint, specifically the 24-pin PDIP configuration. Check RoHS compliance status, as older Cypress PLDs may not meet current environmental directives. Ensure programming equipment compatibility with Cypress Flash PAL devices.

Programmable Logic Device Pld Selection Notes

Select this component when reprogrammability is required compared to one-time programmable PALs like the PALC22V10. Choose the 5 ns variant for applications demanding higher clock frequencies than the 10 ns or 15 ns versions. Consider the PDIP package only if through-hole mounting is necessary; surface mount alternatives like LCC or PLCC are available for different board layouts.

Programmable Logic Device Pld Part Context

This part belongs to the PALCE22V10 family, which represents Cypress's second-generation electrically erasable PLDs. It succeeds the OTP PALC22V10 series by adding Flash memory capabilities. The device competes with other EE PLDs offering similar I/O counts and macrocell flexibility, providing a bridge between simple logic gates and complex FPGAs.

Programmable Logic Device Pld Replacement Considerations

Direct pin-compatible replacements include other PALCE22V10 variants with different speed grades (e.g., PALCE22V10-10, PALCE22V10-15). Military-grade equivalents such as 5962-8984103LX offer identical functionality with extended temperature ranges. Verify that substitute parts maintain the same macrocell architecture and I/O configuration.
