GAL20XV10B-15LJ

Programmable Logic Device Pld Overview

The GAL20XV10B-15LJ is a Complex Programmable Logic Device (CPLD) manufactured by Lattice Semiconductor Corporation. It belongs to the GAL20XV10 family, utilizing high-speed E2CMOS technology and electrically erasable floating gate architecture. The device features 10 macrocells and operates with a maximum propagation delay of 15 nanoseconds. It is housed in a 28-pin Plastic Leaded Chip Carrier (PLCC) package, measuring 11.51 x 11.51 mm. This component serves as a generic array logic solution for digital design applications requiring reprogrammability.

Programmable Logic Device Pld Feature Summary

• Integrates high-performance CMOS process with electrically erasable floating gate technology for non-volatile programmability.

Programmable Logic Device Pld Applications

• Digital logic replacement
• State machine implementation
• Address decoding

Programmable Logic Device Pld Procurement Notes

Verify the specific suffix '15LJ' against official Lattice documentation to confirm the 15ns speed grade and PLCC package type. Ensure compatibility with existing board footprints for 28-PLCC components. Cross-reference the manufacturer part number to distinguish from similar GAL20V or GAL16 variants within the same product family.

Programmable Logic Device Pld Selection Notes

Select this component when a reprogrammable logic solution with electrical erasability is required. The 10-macrocell capacity suits simple logic functions. The 15ns delay specification defines the timing performance. Consider the 28-PLCC package constraints for PCB layout and thermal management during the initial design phase.

Programmable Logic Device Pld Part Context

This device is part of the GAL20XV10 series, representing Lattice's early CPLD offerings based on E2CMOS technology. It provides a bridge between traditional PALs and modern FPGAs, offering user-reprogrammability without the complexity of larger FPGA architectures. The series supports various speed grades and package options.

Programmable Logic Device Pld Replacement Considerations

Direct replacements include other GAL20XV10 variants with compatible pinouts, such as different speed grades like GAL20XV10B-10LJ. Verify that substitute parts maintain the same 28-PLCC footprint and logical functionality before integration.
