AT17C65-10JI

Overview

The AT17C65-10JI is a 64K-bit (65,536 x 1-bit) serial EEPROM configurator designed for Field Programmable Gate Arrays. It operates at 5V nominal voltage within an industrial temperature range of -40°C to +85°C. The device utilizes a simple serial interface with CLK and DATA pins to load configuration programs into FPGA devices in Master Serial Mode. It features programmable reset polarity, low-power standby mode, and write protection capabilities.

Feature Summary

• Designed specifically as a configuration memory source for FPGA devices supporting Master Serial Mode
• Features a simple two-wire serial interface for loading configuration data directly to FPGAs
• Includes programmable reset polarity to adapt to different FPGA control logic requirements
• Supports cascading for expanded memory capacity in complex multi-FPGA systems

Applications

• Configuration of Atmel AT6000 and AT40K series FPGAs
• Configuration of Altera FLEX devices
• Configuration of Xilinx XC3000, XC4000, XC5200, and SPARTAN FPGAs
• Configuration of Lucent ORCA and Motorola MPA1000 FPGAs

Procurement Notes

Verify the suffix 'JI' corresponds to the Industrial temperature range (-40°C to +85°C) and 20-lead PLCC package. Confirm the 'C' designation indicates 5V operation rather than 3.3V LV versions. Ensure programming tools support the specific 2-wire serial protocol defined in the datasheet.

Selection Notes

Select this component when configuring single or multiple smaller FPGAs requiring serial configuration. Choose the 5V version for standard 5V logic systems. Consider the PLCC package for pin-compatible family upgrades. Verify FPGA compatibility with the Master Serial Mode interface before implementation.

Part Context

This part belongs to the AT17 Series of FPGA Configuration EEPROMs manufactured by Atmel. The series includes 64K, 128K, and 256K density options. The 'C' variant denotes 5V operation, while 'LV' variants are for 3.3V systems. The 'J' suffix indicates the 20-lead PLCC package format.

Replacement Considerations

AT17C65-10PC, AT17C65-10NI, AT17C65-10SI offer alternative packages or commercial temperature ranges. AT17LV65-10JI is the 3.3V equivalent. Cross-model replacements within the AT17 family maintain pin compatibility across packages.
