AT17C002A-10JC

Overview

The AT17C002A-10JC is a 2-Mbit serial configuration EEPROM designed for FPGA programming. It features a 20-lead PLCC package and operates at 5V ± 5%. The device stores configuration programs for Altera FLEX devices, supporting in-system programming via a 2-wire bus. It includes a READY pin for power-up status indication and allows programmable reset polarity.

Feature Summary

• Stores configuration data for Field Programmable Gate Arrays using a simple serial-access procedure
• Supports cascading multiple devices to configure larger arrays or higher-density systems
• Enables in-system programming through a 2-wire serial interface
• Provides an open-collector READY pin to indicate power-on reset completion

Applications

• Configuration of Altera FLEX devices
• System master loading for FPGA devices
• Cascaded configuration chains for high-density arrays

Procurement Notes

Verify the component matches the specific 20-lead PLCC package designation. Confirm the voltage rating aligns with the 5V ± 5% requirement for the AT17C variant rather than the 3.3V LV version. Ensure the commercial temperature range meets system specifications.

Selection Notes

Select this part when configuring Altera FLEX devices requiring 2-Mbit capacity. Choose the 5V version for standard logic levels. Consider the TQFP package if surface-mount space constraints differ from PLCC requirements. Verify compatibility with existing FPGA control signals.

Part Context

This component belongs to the AT17A Series of FPGA Configuration EEPROMs. It serves as a configurator memory solution, replacing older serial configuration memories. The series supports both 5V and 3.3V operation across different package options.

Replacement Considerations

The datasheet identifies the AT17C/LV002A series as a replacement for Altera EPC2 devices. No direct Atmel-to-Atmel substitute part numbers are listed for this specific suffix.
