Programmable Logic Device Pld Procurement Notes

This component has been officially discontinued per Product Change Notification PCN#06-07. No new units are manufactured by Lattice Semiconductor. Verification of availability requires checking third-party distributors for existing inventory. Sourcing should focus on verifying the authenticity and condition of surplus stock from authorized channels.

Programmable Logic Device Pld Selection Notes

Designers requiring this specific part number must account for its discontinued status. Selection should prioritize verifying the lead-free package option if required by environmental regulations. Compatibility checks with existing compiler software (e.g., CUPL, LOG/iC) are necessary to ensure proper configuration of the OLMC modes during legacy system maintenance.

Programmable Logic Device Pld Part Context

The GAL16V8D series belongs to the Generic Array Logic family, designed to replace standard bipolar PAL devices. The 'D' suffix indicates the industrial/commercial grade variant using E2CMOS technology. This specific model represents the low-power version within the 25 ns speed bin, offering a balance between performance and power consumption compared to earlier bipolar generations.

Programmable Logic Device Pld Replacement Considerations

Lattice Semiconductor has not listed direct functional replacements in the datasheet. Designers should evaluate modern SPLDs or FPGAs that offer similar I/O counts and pin compatibility. Consultation with Rochester Electronics may be required for potential obsolescence management strategies.
