PALCE22V10-15KMB

Programmable Logic Device Pld Overview

The PALCE22V10-15KMB is a Flash-erasable, reprogrammable CMOS programmable array logic (PAL) device manufactured by Cypress Semiconductor. It features a second-generation architecture with up to 22 input terms and 10 outputs. The component utilizes variable product terms ranging from two times eight to sixteen product terms. It supports user-programmable macrocells that can be configured for registered or combinatorial operation with output polarity control. The specific KMB suffix indicates a ceramic package variant. The device operates within a temperature range of -55°C to +125°C and offers a propagation delay of 15 ns.

Programmable Logic Device Pld Feature Summary

• Flash EPROM technology enabling electrical erasability and reprogrammability without UV exposure
• Configurable macrocells allowing individual selection between registered and combinatorial modes
• Variable product term structure supporting flexible logic implementation
• High reliability with 100% programming and functional testing

Programmable Logic Device Pld Applications

• State machine implementations requiring high-speed clocking
• Address decoding and data routing in embedded systems
• Replacement for legacy fixed-function logic gates in industrial environments
• Prototyping complex digital logic functions before ASIC fabrication

Programmable Logic Device Pld Procurement Notes

Verify the package marking against the official Cypress datasheet to confirm the KMB ceramic package designation. Ensure the order specifies the correct speed grade (-15) and voltage requirements. Check for RoHS compliance status as older military-grade variants may not meet current environmental standards. Confirm availability through authorized distributors given the component's age.

Programmable Logic Device Pld Selection Notes

Select this component when a non-volatile, reprogrammable logic solution is required for harsh environments due to its wide operating temperature range. Compare the 15 ns propagation delay against system timing constraints. Consider the pin count and I/O configuration relative to the target application's interface needs. Evaluate power consumption specifications against available supply rails.

Programmable Logic Device Pld Part Context

This part belongs to the PALCE22V10 family of electrically erasable PLDs. It serves as a drop-in replacement for many standard PAL devices like the GAL22V10, though with enhanced reprogrammability. The family includes various speed grades and package options to suit different commercial, industrial, and military applications.

Programmable Logic Device Pld Replacement Considerations

Direct replacements include other PALCE22V10 variants with compatible speed grades and packages. Verify pin compatibility with existing PCB layouts. Ensure software tools support the specific device family for programming. Cross-reference with equivalent parts from other manufacturers if Cypress supply is limited.
