AT17C002A-10BJI

Overview

The AT17C002A-10BJI is a 2-megabit FPGA configuration EEPROM memory manufactured by Microchip Technology. It provides 2,097,152 x 1-bit serial storage capacity for Field Programmable Gate Arrays. The device operates with a synchronous interface and is housed in a 20-pin PLCC package. It supports in-system programming via a 2-wire bus and includes a system-friendly READY pin to indicate valid power levels during startup.

Feature Summary

• EE reprogrammable serial memory architecture designed specifically for storing configuration programs for FPGAs
• In-system programmability enabled through a simple 2-wire bus interface
• Supports cascading and read-back capabilities to facilitate higher-density array configurations
• Includes a READY pin to signal stable power conditions to the connected FPGA

Applications

• Configuration of Altera FLEX and APEX devices
• Programming Xilinx XC3000, XC4000, and Virtex FPGAs
• Setup of Lucent ORCA and Atmel AT6000/AT40K/AT94K devices

Procurement Notes

Verify that the specific suffix '10BJI' corresponds to the required voltage version (LV or C) and package type (PLCC). Confirm RoHS compliance status as historical data indicates some variants may not be compliant. Ensure the source document explicitly lists this exact part number rather than the generic family series.

Selection Notes

Select this component when a high-density, reprogrammable solution is needed for SRAM-based FPGAs. Consider its compatibility with existing industry-standard programmers. Evaluate the need for programmable reset polarity and the benefits of the READY pin for reliable system power-up sequences compared to non-configurable memory options.

Part Context

This part belongs to the AT17 Series of FPGA Configurators from Microchip (formerly Atmel). These devices are engineered to replace static configuration methods, offering flexibility for field updates. The series is characterized by low-power CMOS EEPROM processes and pin-compatible packaging across different densities within the family.

Replacement Considerations

The AT17C020 serves as a direct functional substitute within the same product family. Both parts share identical memory density, interface protocols, and physical package dimensions, ensuring drop-in compatibility for FPGA configuration applications.
