AT17C65-10PI

Overview

The AT17C65-10PI is a 64K-bit (65,536 x 1-bit) serial EEPROM configurator manufactured by Atmel. It operates at a nominal 5V supply voltage and supports an industrial temperature range of -40°C to +85°C. The device is housed in an 8-pin Plastic Dual Inline Package (PDIP). It features a simple serial interface for FPGA configuration, including programmable reset polarity and low-power standby mode.

Feature Summary

• Designed specifically for storing configuration programs for Field Programmable Gate Arrays (FPGAs)
• Supports In-System Programming via a 2-wire serial bus
• Features programmable reset polarity for flexible system integration
• Compatible with various FPGA families including Xilinx, Altera, and Atmel devices

Applications

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

Procurement Notes

Verify the manufacturer origin, as this component was originally produced by Atmel Corporation. Confirm that the specific ordering code AT17C65-10PI corresponds to the 5V commercial/industrial variant in the 8-pin PDIP package. Ensure compatibility with existing FPGA configuration circuits regarding voltage levels and pin assignments before procurement.

Selection Notes

Select this component when configuring single or multiple smaller FPGAs requiring a cost-effective serial memory solution. It is suitable for designs needing compatibility with legacy FPGA architectures. Consider the 8-pin PDIP package for through-hole assembly requirements. Verify that the 5V operating voltage aligns with the target FPGA's configuration interface specifications.

Part Context

This part belongs to the AT17 Series of FPGA Configuration EEPROMs, which also includes 128K and 256K density variants. The series is designed to provide easy-to-use configuration memory for FPGAs. The 'C' suffix denotes the 5V version, while 'LV' denotes the 3.3V version. The 'I' indicates the industrial temperature range, and 'PI' specifies the 8-pin PDIP package.

FAQ

Can the AT17C65-10PI be used in a cascade chain?

No, the AT17C65 cannot be used in a cascade chain; it can only be used at the end of a cascade chain or as a standalone device.

How is the reset polarity configured?

The reset polarity is programmable as either active High or active Low by programming a special EEPROM byte during the manufacturing or programming phase.

What is the function of the SER_EN pin?

The SER_EN pin must be held High during FPGA loading operations. Bringing SER_EN Low enables the 2-wire Serial Programming Mode.
