AT17LV002-10JU

Overview

The AT17LV002-10JU is a 2-Mbit serial EEPROM designed for FPGA configuration. It supports 3.0V to 5.5V operation and operates within -40°C to +85°C. The device uses a simple serial interface compatible with SRAM FPGAs in Master Serial mode. It features In-System Programmability via a 2-wire bus, cascading capability through the CEO pin, and programmable reset polarity. The component utilizes a low-power CMOS process and offers high reliability with 100,000 write cycles and 90-year data retention.

Feature Summary

• Designed specifically to store configuration programs for Field Programmable Gate Arrays (FPGAs).
• Supports In-System Programming (ISP) via a standard 2-wire serial bus.
• Features cascading capability using the Chip Enable Output (CEO) pin for multi-device configurations.
• Allows user-programmable logic polarity for the RESET/OE function.

Applications

• Configuration of Xilinx Spartan and Virtex series FPGAs.
• Configuration of Altera FLEX and APEX series FPGAs.
• Configuration of Atmel AT6000, AT40K, and AT94K devices.
• Cascaded memory arrays for larger FPGA configuration requirements.

Procurement Notes

Verify that the specific ordering suffix matches the required package type and lead finish. Confirm the voltage range and temperature grade align with system specifications. Ensure compatibility with existing FPGA configuration modes before procurement. Check for any end-of-life notices or recommended new design restrictions associated with this part number.

Selection Notes

Select this component when a 2-Mbit capacity is required for FPGA configuration. Consider the 20-lead PLCC package for board layout constraints. Verify support for both 3.3V and 5.0V systems if voltage flexibility is needed. Evaluate the need for cascading capabilities if single-chip storage is insufficient for the target FPGA.

Part Context

This device belongs to the AT17LV family of FPGA Configuration EEPROMs manufactured by Microchip Technology (formerly Atmel). The family includes various densities ranging from 65-Kbit to 4-Mbit. These configurators provide a cost-effective solution for loading configuration data into SRAM-based FPGAs automatically upon power-up.

Replacement Considerations

AT17LV002-10SU provides the same functionality in a 20-lead SOIC package. AT17LV002-10TQU offers the same density in a 44-lead TQFP package. Cross-package replacements require verification of pinout compatibility and physical footprint constraints.
