AT17F040-30CC

Overview

The AT17F040-30CC is a 4-Mbit In-System Programmable (ISP) Configuration PROM designed for Field Programmable Gate Arrays. It utilizes a low-power CMOS FLASH process and operates on a single 3.3V supply with 5V tolerant I/O pins. The device supports serial configuration via a simple interface compatible with SRAM FPGAs, featuring fast download speeds up to 33 MHz. It offers 5,000 write cycles typical endurance and includes features like cascading read-back and emulation of serial EEPROMs.

Feature Summary

• In-System Programmable via 2-wire bus using industry-standard programmers
• Compatible with major FPGA families including Xilinx, Altera, and Atmel devices
• Supports cascading for multiple configurations or higher-density arrays
• Features low-power standby mode and open-collector ready indicator

Applications

• Configuration memory for Xilinx XC3000, XC4000, and Spartan FPGAs
• Configuration memory for Altera FLEX and APEX devices
• Configuration memory for Atmel AT40K and AT94K devices
• Daisy-chain configuration for multiple FPGA devices

Procurement Notes

Verify the package type matches the required application, as the AT17F040 series is available in 8-lead LAP and 20-lead PLCC packages. Confirm the temperature grade corresponds to the operational environment; the 'CC' suffix indicates Commercial range (0°C to 70°C). Ensure programming equipment supports the 2-wire serial protocol for ISP capabilities.

Selection Notes

Select this component when a cost-effective, serial configuration solution is needed for SRAM-based FPGAs. Consider the 4-Mbit capacity for smaller designs or use cascading for larger bitstreams. Verify that the target FPGA supports Master Serial mode for direct interfacing without an external controller. Check compatibility with existing third-party programmers if ISP functionality is required.

Part Context

The AT17F040 belongs to the AT17F Series of Configurators, which provide easy-to-use configuration memory for FPGAs. This series allows for simple serial-access procedures to configure one or more FPGA devices. The AT17F040 specifically offers 4 Mbits of storage, suitable for holding bit stream files for system reconfiguration.

Replacement Considerations

AT17F040-30JC: Same commercial temperature range but in 20-lead PLCC package. AT17F040-30CI: Industrial temperature range (-40°C to 85°C) in 8-lead LAP package. AT17F040-30JI: Industrial temperature range in 20-lead PLCC package.
