AT17LV040-10TQC

Configuration PROMs For FPGAs Overview

The AT17LV040-10TQC is a 4-Mbit (512K x 8) serial EEPROM configurator designed for FPGA configuration. It operates on 3.3V or 5.0V supplies and supports industrial temperature ranges from -40°C to +85°C. The device features a simple serial interface compatible with FPGA master modes, allowing direct connection without external controllers. It includes programmable reset polarity, write protection mechanisms, and cascading capabilities via the CEO output pin.

Configuration PROMs For FPGAs Replacement Considerations

AT17LV040-10BJC offers identical functionality in a 44-lead PLCC package. AT17LV040-10TQU provides a fully green, RoHS-compliant version in the same TQFP package. Verify package dimensions and pinout compatibility before substitution.

Configuration PROMs For FPGAs FAQ

How does the device handle cascading configurations?

The device uses its CEO output pin to signal completion to the next device in the chain. When the address counter reaches its maximum value, CEO goes Low, enabling the CE input of the subsequent configurator.

Is the reset polarity fixed?

No, the reset polarity is programmable. Users can configure the RESET/OE pin to be active High or active Low by programming four specific EEPROM bytes during initialization.
