AT17F080-30CI

Overview

The AT17F080-30CI is an 8-Mbit serial configuration PROM designed for Field Programmable Gate Arrays. It operates on a single 3.3V supply with 5V tolerant I/O pins and supports industrial temperature ranges from -40°C to +85°C. The device utilizes a simple 2-wire serial interface for in-system programming and FPGA configuration, featuring fast download speeds up to 33 MHz. It includes features such as low-power standby mode, cascading capability for higher-density arrays, and emulation of serial EEPROMs.

Feature Summary

• Supports In-System Programming (ISP) via a 2-wire bus for flexible configuration updates.
• Provides direct compatibility with SRAM-based FPGAs through Master Serial Mode operation.
• Enables daisy-chaining of multiple devices to support larger configuration memory requirements.
• Features low-power CMOS FLASH process technology with dedicated standby mode.

Applications

• Configuration of Xilinx XC3000, XC4000, and Spartan series FPGAs
• Programming Altera FLEX and APEX device families
• Storing configuration bitstreams for Atmel AT40K and AT94K devices
• Cascaded configuration setups for high-density FPGA arrays

Procurement Notes

Verify the specific package type required, as the AT17F080-30CI designation corresponds to the Industrial temperature range (-40°C to +85°C). Confirm that the ordering suffix matches the desired physical package, such as the 20-lead PLCC or 44-lead TQFP, as availability varies by form factor. Ensure compatibility with existing ISP programmers like the Atmel ATDH2200E system before procurement.

Selection Notes

Select this component when designing systems requiring non-volatile storage for FPGA configuration data in industrial environments. It is suitable for applications needing 5V tolerant interfaces while operating at 3.3V. Consider cascading options if the design requires more than 8 Mbits of configuration space. Verify that the target FPGA supports the Master Serial configuration mode for direct interfacing without external controllers.
