Programmable Logic Device Pld Procurement Notes

This component is officially discontinued per Product Change Notification PCN#13-10. No new production units are available from the manufacturer. Verification of existing stock should be conducted through authorized distributors, noting that availability is limited and subject to final inventory status.

Programmable Logic Device Pld Selection Notes

Select this part only if legacy compatibility with standard 22V10 fuse maps is required. The -25 speed grade offers a 25 ns maximum propagation delay. Ensure designs account for the commercial temperature range (0°C to +75°C) and 5V power supply constraints. Verify programming tool support for the GAL22V10 architecture.

Programmable Logic Device Pld Part Context

The GAL22V10D series represents a high-performance CMOS implementation of the generic 22V10 architecture. It provides full functional and parametric compatibility with older bipolar and UVCMOS 22V10 devices while offering significantly lower power consumption. The 'D' suffix denotes the specific device variant within the GAL family.

Programmable Logic Device Pld Replacement Considerations

Public confirmed substitute part numbers are not provided in the source material. Due to the discontinued status, alternative solutions require evaluation of modern SPLDs or CPLDs that match the pinout and logic density requirements.

Programmable Logic Device Pld FAQ

What is the maximum number of erase/write cycles?

The device supports 100 erase/write cycles.

How does the device handle unused inputs?

Built-in active pull-ups cause floating inputs to float to a TTL high (logic 1), though connecting them to Vcc or ground is recommended for noise immunity.

Is the electronic signature affected by the security cell?

No, the electronic signature remains accessible to the user regardless of the state of the security cell.
