AT17C65A-10JI

Overview

The AT17C65A-10JI is a 64-Kbit serial EEPROM configurator designed for Altera FLEX devices. It operates at 5V nominal voltage within an industrial temperature range of -40°C to +85°C. The device utilizes a 20-lead PLCC package and supports in-system programming via a 2-wire bus. It features a simple serial interface compatible with SRAM FPGAs, allowing direct configuration without external controllers.

Feature Summary

• Supports in-system programming through a 2-wire serial bus interface
• Enables programmable reset polarity for flexible FPGA integration
• Provides cascading capability for expanded configuration storage
• Emulates Atmel's AT24CXXX serial EEPROM functionality

Applications

• Configuring Altera FLEX devices
• Storing configuration programs for Field Programmable Gate Arrays
• Simple interface connections to SRAM FPGAs

Procurement Notes

Verify the specific ordering suffix 'I' confirms the industrial temperature rating (-40°C to +85°C) and 5V operation. Ensure compatibility with Altera FLEX device pinouts and timing requirements. Confirm that the 20-lead PLCC package matches the target PCB footprint and soldering specifications.

Selection Notes

Select this component when configuring Altera FLEX devices requiring 64-Kbit capacity. Choose the 'C' suffix for commercial temperature ranges or 'LV' variants for 3.3V systems. Verify that the 5V supply voltage aligns with the system design constraints and that the PLCC package fits the assembly process.

Part Context

This part belongs to the AT17A Series low-density FPGA configuration EEPROMs. The family includes 64K, 128K, and 256K bit densities. These devices are specifically engineered to store configuration data for Altera FLEX devices, offering a cost-effective solution for field-programmable gate array initialization.

Replacement Considerations

Use 64-Kbit density parts to replace Altera EPC1064.
