AT17LV002A-10QI

Overview

The AT17LV002A-10QI is a 2-Mbit (2,097,152 x 1-bit) serial EEPROM configurator designed for FPGA configuration. It operates on a single 3.3V or 5.0V supply and supports industrial temperature ranges from -40°C to +85°C. The device utilizes a simple 2-wire serial interface compatible with Altera FLEX and APEX SRAM-based FPGAs. It features in-system programmability via a 2-wire bus, cascading capabilities for expanded memory arrays, and high-reliurance specifications including 100,000 write cycles and extended data retention.

Feature Summary

• Provides non-volatile storage for FPGA configuration programs using a low-power CMOS EEPROM process.
• Supports in-system programming through a standard 2-wire serial bus interface.
• Enables daisy-chaining of multiple devices via cascade outputs to support larger configuration arrays.
• Allows user-programmable reset polarity and includes internal write-protection mechanisms.

Applications

• Configuration of Altera FLEX and APEX series Field Programmable Gate Arrays
• In-system programming of FPGA configuration memory
• Cascaded memory systems for high-density FPGA applications

Procurement Notes

Verify the specific ordering suffix 'QI' corresponds to the 32-lead TQFP package and Industrial temperature range (-40°C to +85°C). Confirm that the design requires 2-Mbit capacity and 3.3V/5V compatibility. Ensure the target FPGA supports Master Serial mode for direct interfacing without external controllers.

Selection Notes

Select this component when configuring Altera FLEX or APEX FPGAs requiring 2-Mbit capacity. It is suitable for designs needing industrial temperature stability and in-system programmability. Consider cascading options if additional memory density is required beyond the single-device limit.

Part Context

This part belongs to the AT17A series of FPGA configuration EEPROMs manufactured by Microchip Technology (formerly Atmel). The series offers various densities from 64-Kbit to 2-Mbit, providing pin-compatible packages across the family to simplify board layout upgrades.

Replacement Considerations

AT17LV002A-10QC: Commercial temperature variant (-0°C to +70°C) in the same 32-lead TQFP package.

FAQ

Does the AT17LV002A support JTAG programming?

No, the AT17LV002A does not support JTAG programming; it uses a 2-wire serial interface for in-system programming.

How is the reset polarity configured?

The polarity of the RESET/OE pin can be programmed by the user during the programming phase to suit specific FPGA requirements.
