AT17LV002-10TQI

Overview

The AT17LV002-10TQI is a 2-megabit serial EEPROM designed for FPGA configuration. It operates within a supply voltage range of 3.0V to 3.6V and supports an industrial temperature range of -40°C to +85°C. The device utilizes a low-power CMOS process and features a simple two-wire bus interface for in-system programming. It includes a system-friendly READY pin to indicate power stability and allows programmable reset polarity. The component is housed in a 44-lead Thin Plastic Quad Flat Package (TQFP) with a 1.0mm body thickness.

Feature Summary

• Designed specifically to store configuration programs for Field Programmable Gate Arrays
• Supports In-System Programming via a two-wire serial bus interface
• Features a system-friendly READY pin that indicates valid power levels during startup
• Allows user-programmable reset polarity through four EEPROM bytes

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
• Cascaded configurations for higher-density FPGA arrays

Procurement Notes

Verify the specific ordering suffix to confirm the package type and operating temperature range. Ensure the voltage variant matches the target system requirements, as this part number corresponds to the 3.3V LV version. Confirm RoHS compliance status and lead-free availability based on current manufacturing specifications before finalizing procurement orders.

Selection Notes

Select this component when a high-density serial configurator is required for SRAM-based FPGAs. It serves as a drop-in replacement for legacy PROMs like the XC17/ATT17 series. Consider cascading capabilities if the design requires more than 2 megabits of configuration data. Verify compatibility with the specific FPGA master serial mode timing requirements.

Part Context

This device belongs to the AT17 Series of FPGA Configuration EEPROMs manufactured by Microchip Technology (formerly Atmel). The series provides cost-effective memory solutions for programming Field Programmable Gate Arrays. The AT17LV002-10TQI represents the low-voltage variant packaged in a 44-lead TQFP, suitable for industrial applications requiring reliable operation across a wide temperature range.

Replacement Considerations

The datasheet identifies the AT17C/LV020 as a predecessor device replaced by the AT17 Series. For direct functional replacements within the same family, consider other AT17LV002 variants with different packages such as PLCC or LAP, provided pin compatibility is maintained.
