AT17C65-10JC

Overview

The AT17C65-10JC is a 64K-bit (65,536 x 1-bit) serial EEPROM configurator designed for Field Programmable Gate Arrays. It operates at a nominal 5V supply voltage and supports an industrial temperature range of -40°C to +85°C. The device utilizes a simple serial interface with a clock input to increment internal address counters for reading configuration programs. It features a low-power standby mode and programmable reset polarity. The component is housed in a 20-lead Plastic J-leaded Chip Carrier (PLCC) package.

Feature Summary

• Designed specifically as a configuration memory source for FPGA devices via Master Serial Mode
• Supports In-System Programming through a 2-wire serial bus interface
• Includes a cascading capability feature allowing multiple units to be linked for larger configurations
• Features programmable reset polarity to adapt to different FPGA control logic requirements

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 specific suffix 'JC' corresponds to the 20-lead PLCC package and Industrial temperature rating (-40°C to +85°C). Confirm that the design requires a 5V nominal supply, as this variant differs from the LV (Low Voltage) series which operates at 3.3V. Ensure compatibility with the target FPGA's Master Serial Mode timing requirements before finalizing procurement.

Selection Notes

Select this part when configuring single or smaller FPGAs requiring 64K bits of storage. Choose the Industrial grade version if the operating environment exceeds commercial temperature limits. Consider the 128K or 256K variants only if cascading support is required, as the 65K model cannot drive a cascade chain output. Verify that the system architecture supports the 20-lead PLCC footprint.

Part Context

This component belongs to the AT17 Series of FPGA Configuration EEPROMs manufactured by Atmel. The family includes 64K, 128K, and 256K density options available in both 5V (AT17C) and 3.3V (AT17LV) versions. These devices serve as non-volatile memory sources that automatically load configuration data into compatible FPGAs upon power-up or command.

Replacement Considerations
