AT17C010A-10JC

Overview

The AT17C010A-10JC is a 1-Mbit serial EEPROM configurator designed for Altera FLEX devices. It operates at 5V nominal voltage within the commercial temperature range of 0°C to +70°C. The device is housed in a 20-lead Plastic J-leaded Chip Carrier (PLCC) package. It features an internal oscillator for master configuration mode and supports cascading via the nCASC pin. Key control signals include OE, nCS, DCLK, and DATA. A READY pin indicates power-on reset status, and WP1 provides write protection.

Feature Summary

• Stores configuration programs for Altera FLEX field programmable gate arrays
• Supports cascading read-back for multiple device configurations
• Allows programmable reset polarity selection via EEPROM bytes
• Enables in-system programming through a 2-wire serial interface

Applications

• Configuring Altera FLEX FPGA devices
• Storing configuration data for single or multiple smaller FPGAs
• Cascaded configuration chains for higher-density arrays

Procurement Notes

Verify the specific suffix JC corresponds to the 20-lead PLCC package and commercial temperature grade. Confirm the 5V supply requirement matches the system design. Ensure compatibility with Altera FLEX device protocols. Check for obsolescence status as this component originates from Atmel/Microchip legacy lines. Validate that the industrial programmer supports the AT17A series specifications.

Selection Notes

Select this part when configuring Altera FLEX devices requiring 1-Mbit capacity. Choose the 5V version for systems operating at standard logic levels. Consider the PLCC package for surface-mount applications needing space efficiency. Evaluate cascading requirements if configuration data exceeds single-device capacity. Verify that the internal clock generation meets the FPGA timing constraints without external clock sources.

Part Context

This component belongs to the AT17A Series of FPGA Configuration EEPROMs. It serves as a cost-effective memory solution for programming Altera FLEX devices. The series includes 512-Kbit and 1-Mbit variants. It emulates Atmel’s AT24CXXX serial EEPROMs for compatibility. The device simplifies system power-up considerations with its READY pin feature.

Replacement Considerations

Use 512-Kbit density parts to replace Altera EPC1441. Use 1-Mbit density parts to replace Altera EPC1.
