AT17LV002-10JI

Overview

The AT17LV002-10JI is a 2-Mbit serial EEPROM configurator designed for FPGA configuration. It operates within a supply voltage range of 3.0V to 5.5V and supports an industrial temperature range of -40°C to +85°C. The device utilizes a simple two-wire serial interface for in-system programming and direct connection to SRAM FPGAs. It features programmable reset polarity, write protection mechanisms, and cascading capabilities via the CEO output pin.

Feature Summary

• Supports both 3.3V and 5.0V operating voltage applications
• Enables in-system programming via a two-wire bus
• Allows user-programmable reset polarity through four EEPROM bytes
• Provides cascading read-back support for higher-density arrays

Applications

• Configuration memory for Xilinx XC3000, XC4000, and Virtex FPGAs
• Configuration memory for Altera FLEX and APEX devices
• Configuration memory for Atmel AT6000, AT40K, and AT94K devices
• Cascaded configurations for multiple FPGA systems

Procurement Notes

Verify that the ordering suffix 'JI' corresponds to the 20-lead PLCC package and the industrial temperature grade (-40°C to +85°C). Confirm compliance with specific environmental directives such as RoHS if required by the application, noting that green package options may be available under different suffixes. Ensure the design accounts for the specific pinout differences between smaller and larger capacity devices in the series.

Selection Notes

Select this component when a 2-Mbit capacity is required for FPGA configuration. The industrial temperature rating makes it suitable for harsh environments. Consider the 20-lead PLCC package constraints during PCB layout. Verify compatibility with the target FPGA's master serial mode requirements and ensure the system supports the necessary two-wire programming interface for field updates.

Part Context

This part belongs to the AT17LV series of FPGA Configuration EE PROMs manufactured by Microchip Technology (formerly Atmel). The series provides cost-effective configuration memory solutions for various SRAM-based FPGAs. The AT17LV002 specifically offers 2-Mbit density, bridging the gap between lower-capacity devices like the AT17LV512 and higher-capacity devices like the AT17LV040.

Replacement Considerations

Customers using older -10SC or -10SI packages may migrate to the AT17LVXXX-10SU. For TQFP packages, migration to the AT17LVXXX-10TQU is supported. Direct pin-compatible replacements within the same package type should be verified against the latest ordering information table.
