AT17C65-10SC

Overview

The AT17C65-10SC 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 the industrial temperature range of -40°C to +85°C. The device utilizes a simple 2-wire serial interface and supports in-system programming via a dedicated serial enable pin. It features programmable reset polarity and write protection mechanisms. The component is housed in an 8-lead SOIC package.

Feature Summary

• Designed specifically for storing configuration programs for FPGA devices
• Supports in-system programming through a 2-wire serial bus interface
• Features programmable reset polarity and internal write-protection capabilities
• Compatible with various industry-standard FPGA architectures

Applications

• Configuration memory for Atmel AT6000 and AT40K FPGAs
• Configuration storage for Altera FLEX devices
• Configuration storage for Xilinx XC3000, XC4000, and SPARTAN FPGAs
• Configuration storage for Lucent ORCA and Motorola MPA1000 FPGAs

Procurement Notes

Verify that the specific ordering suffix matches the required package type and operating temperature range. Confirm the supply voltage requirement aligns with the system design, as this model is a 5V device distinct from the LV series. Ensure compatibility with existing FPGA configuration protocols before procurement.

Selection Notes

Select this component when configuring low-density FPGAs requiring serial EEPROM support. Consider the AT17LV65 variant if the system operates at 3.3V instead of 5V. Evaluate cascading requirements, noting that the 65K density is suitable for standalone use or end-of-chain positions rather than primary cascade sources.

Part Context

This part belongs to the AT17 Series of FPGA Configuration EEPROMs manufactured by Atmel Corporation. The series includes variants with different memory densities and voltage levels. The AT17C65 provides 64K bits of non-volatile storage specifically optimized for loading configuration data into compatible programmable logic devices.
