AT17F080A-30CU

Overview

The AT17F080A-30CU is an 8-Mbit serial configuration memory device designed for Field Programmable Gate Arrays (FPGAs). It operates on a single 3.3V supply with 5.0V tolerant I/O pins and supports in-system programming via a 2-wire bus. The component utilizes a low-power CMOS FLASH process, offering 100,000 write cycles typical endurance and fast serial download speeds up to 33MHz. It features page download mode support for storing multiple bitstreams and cascading capabilities for higher-density arrays.

Feature Summary

• Supports In-System Programming (ISP) via a 2-wire serial bus using standard programmers or dedicated Atmel kits.
• Provides simple serial access interface compatible with SRAM-based FPGAs without requiring external intelligent controllers.
• Enables storage of multiple configuration bitstreams through configurable page download mode.
• Allows daisy-chaining of devices to expand configuration memory capacity for larger FPGA arrays.

Applications

• Configuration of Altera FLEX, Excalibur, Stratix, Cyclone, and APEX devices
• Configuration of Atmel AT40K and AT94K series devices
• Reconfiguration of Xilinx FPGA devices

Procurement Notes

Verify the specific package type required for your design, as the AT17F080A is available in both 8-pad LAP and 20-lead PLCC formats. Confirm that the industrial temperature range (-40°C to +85°C) meets your operational environment requirements. Ensure compatibility with your chosen programming hardware, such as the ATDH2200E system or third-party programmers, before finalizing procurement.

Selection Notes

Select this component when designing systems requiring non-volatile configuration storage for SRAM-based FPGAs. It is suitable for applications needing cost-effective configurators with high endurance and fast download speeds. Consider the 8-Mbit density for smaller to medium-sized FPGA configurations or use cascading for larger designs. Verify pin compatibility if replacing legacy Atmel or Altera configuration PROMs.

Part Context

This part belongs to the AT17FxxxA Series of In-System Programmable Configuration PROMs manufactured by Microchip Technology (formerly Atmel). These devices are specifically engineered to provide easy-to-use, cost-effective configuration memory solutions for various FPGA families. The series supports both serial programming and direct FPGA interfacing, making it a versatile choice for embedded logic configuration tasks.

Replacement Considerations

The AT17F080A-30JU serves as a pin-compatible alternative within the same family, differing only in package style (20-lead PLCC vs. 8-pad LAP). When substituting, ensure the target board layout accommodates the physical dimensions of the replacement package. Verify that the programming equipment supports the specific package being used.
