AT17LV512A-10JU

Configuration PROMs For FPGAs Overview

The AT17LV512A-10JU is a 512-kbit serial EEPROM designed for FPGA configuration. It operates at 3.0V to 5.5V and supports industrial temperatures from -40°C to +85°C. The device uses a simple serial interface compatible with SRAM-based FPGAs in Master Serial mode. It features In-System Programmability (ISP) via a 2-wire bus, allowing updates without removal. The memory organization is 524,288 x 1-bit. It includes programmable reset polarity and cascading capabilities through the CEO pin.

Configuration PROMs For FPGAs Feature Summary

• Designed specifically for storing configuration programs for Field Programmable Gate Arrays (FPGAs).
• Supports In-System Programming (ISP) using a standard 2-wire serial bus interface.
• Features a cascading output (CEO) pin that enables connection of multiple devices for larger arrays.
• Includes a programmable reset polarity feature to match specific FPGA control signal requirements.

Configuration PROMs For FPGAs Applications

• Configuration memory for Xilinx XC3000, XC4000, XC5200, Spartan, and Virtex FPGAs.
• Configuration storage for Altera FLEX and APEX devices.
• Configuration storage for Atmel AT6000, AT40K, and AT94K devices.
• Daisy-chained FPGA systems requiring expanded configuration memory capacity.

Configuration PROMs For FPGAs Procurement Notes

Verify the package type matches the design footprint; the 'J' suffix indicates a 20-lead PLCC package. Confirm the voltage range requirement aligns with the 3.0V to 5.5V specification. Ensure the programming tool supports the 2-wire ISP mode if field updates are required. Check for lead-free status as indicated by the 'U' designation in the ordering code.

Configuration PROMs For FPGAs Selection Notes

Select this component when an FPGA requires non-volatile configuration storage with low power consumption. It is suitable for designs needing compatibility with legacy Atmel or major FPGA families. Consider the 20-lead PLCC package availability against board space constraints. Verify that the maximum clock frequency meets the system timing requirements.
