AT17LV002A-10JU

Overview

The AT17LV002A-10JU is a 2-Mbit (2,097,152 x 1-bit) serial configuration EEPROM designed for FPGA programming. It supports both 3.3V and 5.0V operating voltages with an industrial temperature range of -40°C to +85°C. The device features in-system programmability via a 2-wire bus and provides high endurance of 100,000 write cycles with 90-year data retention. Packaged in a 20-lead PLCC, it interfaces directly with SRAM-based FPGAs using standard control signals.

Feature Summary

• Supports both 3.3V and 5.0V system applications
• In-system programmable via 2-wire serial bus
• Cascadable read-back capability for multi-device configurations
• Programmable reset polarity for diverse FPGA requirements

Applications

• Configuration memory for Altera FLEX and APEX FPGAs
• Configuration memory for Xilinx XC3000, XC4000, and Virtex FPGAs
• Configuration memory for Atmel AT6000, AT40K, and AT94K devices
• Daisy-chain FPGA array configuration systems

Procurement Notes

Verify the specific density suffix '002' corresponds to the required 2-Mbit capacity. Confirm the package code 'J' matches the 20-lead PLCC requirement. Ensure the voltage range covers both 3.3V and 5.0V needs. Check that the industrial temperature grade meets environmental specifications. Validate compatibility with existing FPGA master serial mode designs.

Selection Notes

Select this component when a non-volatile configuration solution supporting dual voltage levels is required. It is suitable for replacing older EEPROM configurators in established FPGA designs. Consider its cascading feature if multiple memory devices are needed for larger bitstreams. Verify pin compatibility with legacy PLCC footprints during PCB layout planning.

Part Context

This part belongs to the AT17LVxxxA family of FPGA configuration EEPROMs manufactured by Microchip Technology (formerly Atmel). These devices serve as cost-effective configurators for various SRAM-based FPGAs. The family includes lower-density variants like the AT17LV512A and AT17LV010A, offering scalable memory options for different FPGA configuration sizes.

Replacement Considerations

The AT17LV65A, AT17LV128A, and AT17LV256A are not recommended for new designs and have been replaced by the AT17LV512A. For direct functional replacement within the same density class, verify pinout compatibility with other 20-lead PLCC serial EEPROMs from the same manufacturer family.
