PALCE26V12H-10JC/4

Overview

The PALCE26V12H-10JC/4 is a high-performance Programmable Logic Device (PLD) manufactured by Lattice Semiconductor Corporation. It belongs to the PALCE family, featuring 12 macrocells for complex logic implementation. The device operates with a maximum propagation delay of 10 ns, ensuring fast signal processing capabilities. It is housed in a 28-pin Plastic Leaded Chip Carrier (PLCC) package, measuring 11.51x11.51 mm, which facilitates surface-mount integration into various electronic circuits.

Feature Summary

• Utilizes PAL-type architecture for flexible combinatorial and registered logic functions
• Provides instant-on capability without requiring external configuration memory
• Supports high-speed operation with low propagation delays for critical timing paths

Applications

• General-purpose digital logic replacement for standard TTL or CMOS gates
• Address decoding and chip select generation in memory systems
• Control logic implementation for industrial automation interfaces
• Signal routing and protocol conversion in embedded communication modules

Procurement Notes

Verify component authenticity through authorized distributors or certified suppliers. Confirm that the part number matches the exact suffix specifications. Check for obsolescence notices from Lattice Semiconductor regarding fabrication site transitions. Ensure storage conditions comply with moisture sensitivity levels prior to reflow soldering processes.

Selection Notes

Select this component when designing systems requiring moderate logic density with fast switching speeds. Consider the 28-PLCC package constraints for board space limitations. Evaluate power consumption requirements against system thermal management capabilities. Compare against newer CPLD families if higher pin counts or advanced features are needed.

Part Context

This device is part of Lattice's legacy PALCE series, designed for cost-effective logic solutions. It serves as a direct upgrade path for older GAL devices like the GAL26V12C. The product line emphasizes reliability and ease of use for designers transitioning from fixed-function logic to programmable alternatives.

Replacement Considerations

The GAL26V12C-10LJ is listed as a compatible substitute in official conversion guides. Verify pinout compatibility and electrical characteristics before substitution. Ensure programming tools support both original and replacement part numbers.
