AT17C002-10JI

Overview

The AT17C002-10JI is a 2-megabit (2,097,152 x 1-bit) serial configuration EEPROM designed for Field Programmable Gate Arrays. It operates at a nominal 5V supply voltage with an industrial temperature range of -40°C to +85°C. The device utilizes a simple serial interface compatible with FPGA master modes and supports in-system programming via a 2-wire bus. It is housed in a 20-lead Plastic Leaded Chip Carrier (PLCC) package.

Feature Summary

• EE reprogrammable memory architecture optimized for storing FPGA configuration programs
• In-system programmability enabled through a standard 2-wire serial bus interface
• Programmable reset polarity allowing flexible logic level configuration
• System-friendly READY pin indicating power-up completion status

Applications

• Configuration of Xilinx XC3000, XC4000, XC5200, Spartan, and Virtex FPGAs
• Programming Altera FLEX and APEX devices
• Configuration of Atmel AT6000, AT40K, and AT94K devices
• Lucent ORCA FPGA system initialization

Procurement Notes

Verify the specific suffix 'JI' corresponds to the Industrial temperature grade (-40°C to +85°C) and 5V operation. Confirm the package type matches the required 20-lead PLCC footprint. Ensure the design accounts for the non-RoHS compliance indicated in some legacy databases, as this part may not meet current environmental directives depending on the manufacturing date code.

Selection Notes

Select this component when a high-density, cost-effective configurator is needed for SRAM-based FPGAs requiring a simple serial interface. It serves as a drop-in replacement for older PROMs like the XC17/ATT17 series. Consider the cascading capability if the target FPGA requires more than 2 megabits of configuration data, utilizing the CEO output to chain multiple units.

Part Context

This device belongs to the AT17 Series of FPGA Configuration EEPROMs manufactured by Atmel, now Microchip Technology. The series provides a standardized solution for loading configuration bitstreams into various FPGA architectures without requiring complex parallel interfaces or external microcontrollers for the initial boot process.

Replacement Considerations

• AT17LV002-10JI (3.3V version)
• AT17C002-10JC (Commercial temperature grade)
