Configuration PROMs For FPGAs Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure compatibility with existing FPGA master serial mode requirements. Confirm that the 20-lead PLCC footprint matches the target PCB design. Check for any recent product change notices regarding pinout or electrical characteristics updates.

Configuration PROMs For FPGAs Selection Notes

Select this component when a 512-Kbit capacity is required for FPGA configuration. Choose the industrial temperature grade (-40°C to +85°C) for environments exceeding commercial limits. Consider cascading options if larger configuration arrays are needed. Verify voltage supply constraints align with the 3.3V or 5V system designs supported by the device.

Configuration PROMs For FPGAs FAQ

How is the reset polarity configured?

The polarity of the RESET/OE pin is programmable by the user during the programming phase using four specific EEPROM bytes.

What is the function of the nCASC pin?

The nCASC pin outputs a low signal when the address counter reaches its maximum value, allowing it to drive the chip select of the next device in a daisy-chain configuration.
