AT17LV002-10TQC

Overview

The AT17LV002-10TQC is a 2-Mbit (2,097,152 x 1-bit) serial EEPROM designed for FPGA configuration. It operates at 3.3V ± 10% with a maximum clock frequency of 10 MHz in industrial applications and 15 MHz in commercial mode. The device supports In-System Programming via a 2-wire bus and features a system-friendly READY pin. It is housed in a 44-lead Thin Plastic Quad Flat Package (TQFP).

Feature Summary

• Designed to store configuration programs for Field Programmable Gate Arrays.
• Supports In-System Programming via a 2-wire bus interface.
• Features a programmable reset polarity and cascading capability for higher-density arrays.

Applications

• Configuration memory for Atmel AT6000, AT40K, and AT94K devices.
• Configuration memory for Altera FLEX and APEX devices.
• Configuration memory for Xilinx XC3000, XC4000, XC5200, Spartan, and Virtex devices.

Procurement Notes

Verify the specific voltage variant, as the 'LV' designation indicates 3.3V operation. Confirm the package type matches the design requirements, specifically the 44-lead TQFP format. Ensure compatibility with the target FPGA's master serial mode requirements before procurement.

Selection Notes

Select this component when a high-density serial configuration memory is required for SRAM-based FPGAs. The choice between AT17C and AT17LV depends on the system supply voltage; use the LV version for 3.3V systems. Verify that the 44-lead TQFP package fits the available PCB space and routing constraints.

Part Context

This part belongs to the AT17 Series of FPGA Configuration EEPROMs. The series provides cost-effective solutions for programming Field Programmable Gate Arrays using a simple serial-access procedure. The family includes various densities and packages, with the AT17LV002 offering 2-Mbit capacity in low-voltage operation.

Replacement Considerations

The datasheet identifies the AT17C/LV020 as a replacement target. Direct substitutes within the same density and package should be verified against the ordering information table for pin compatibility and electrical specifications.
