AT17LV002-10TQU

Overview

The AT17LV002-10TQU is a 2-Mbit (2,097,152 x 1-bit) serial EEPROM designed for FPGA configuration. It supports 3.3V and 5.0V supply voltages with an operating range of 3.0V to 5.5V. The device operates at a maximum clock frequency of 10 MHz at 3.3V and up to 15 MHz at 5.0V. It features industrial temperature ratings from -40°C to +85°C and is housed in a 44-lead Thin Plastic Quad Flat Package (TQFP).

Feature Summary

• Designed specifically to store configuration programs for Field Programmable Gate Arrays (FPGAs)
• Supports In-System Programming (ISP) via a 2-wire bus interface
• Features cascading capability through the Chip Enable Output (CEO) pin for expanded memory arrays
• Includes programmable reset polarity and write protection mechanisms

Applications

• Configuration of Xilinx XC3000, XC4000, XC5200, Spartan, and Virtex FPGAs
• Configuration of Altera FLEX and APEX devices
• Configuration of Atmel AT6000, AT40K, and AT94K devices
• Cascaded memory systems for high-density FPGA configurations

Procurement Notes

Verify that the specific ordering suffix 'TQU' corresponds to the 44-lead TQFP package variant as defined in the manufacturer's official documentation. Confirm compliance requirements such as RoHS status and lead finish specifications against the current datasheet revision. Ensure the design utilizes the correct pinout for the 44-lead TQFP package, noting that pin assignments differ from smaller packages within the same family.

Selection Notes

Select this component when a 2-Mbit capacity is required for FPGA configuration applications. The 44-lead TQFP package is suitable for designs requiring surface-mount technology with specific board space constraints compatible with this footprint. Consider the device's compatibility with both 3.3V and 5.0V logic levels if the target FPGA system operates across these voltage ranges.

Part Context

This part belongs to the AT17LV series of FPGA Configuration EEPROMs manufactured by Microchip Technology (formerly Atmel). The series provides non-volatile memory solutions for loading configuration data into SRAM-based FPGAs. The AT17LV002 represents the 2-Mbit density tier within this product line, offering higher capacity than the 256-Kbit or 512-Kbit variants.

Replacement Considerations

The AT17LV65 and AT17LV128 are explicitly marked as Not Recommended for New Designs (NRND) and are replaced by the AT17LV256. For direct functional replacements within the same density class, consult the official Microchip cross-reference guide for any updated equivalents to the AT17LV002 family.
