GAL20V8B-25QJ

Programmable Logic Device Pld Overview

The GAL20V8B-25QJ is a discontinued Electrically Erasable Programmable Logic Device (PLD) from Lattice Semiconductor. It utilizes E2CMOS technology and features an 8-output architecture with reprogrammable Output Logic Macrocells (OLMCs). The device supports registered, complex, and simple logic modes. Key electrical parameters include a maximum propagation delay of 25 ns, a typical operating supply current of 45 mA for the quarter-power variant, and operation within a +4.50 V to +5.50 V supply range for industrial grades.

Programmable Logic Device Pld Feature Summary

• E2CMOS technology enabling high-speed erasure (<100ms) and 20-year data retention
• Reconfigurable OLMCs supporting registered, complex, and simple modes
• Active pull-ups on all pins and programmable output polarity
• Emulates standard PAL architectures with full function compatibility

Programmable Logic Device Pld Applications

• DMA Control
• State Machine Control

Programmable Logic Device Pld Procurement Notes

This specific part number has been officially discontinued per Product Change Notification (PCN) #13-10. Verification of availability requires checking for obsolete inventory through authorized distributors or third-party suppliers. No new production units are manufactured by Lattice Semiconductor.

Programmable Logic Device Pld Selection Notes

Designers requiring this component must account for its discontinued status. Selection should focus on verifying the package type (PLCC) and speed grade (-25 ns). Alternative modern PLDs or CPLDs from Lattice or other manufacturers should be evaluated for functional equivalence and long-term supply stability.

Programmable Logic Device Pld Part Context

The GAL20V8B series represents the second generation of Generic Array Logic devices from Lattice, succeeding the original GAL20V8C. The 'B' suffix denotes the updated process technology offering improved power consumption characteristics compared to earlier iterations.

Programmable Logic Device Pld Replacement Considerations

GAL20V8B-25QJN is the lead-free version of this device, also discontinued.
