AT17F080-30JU

Overview

The AT17F080-30JU is an 8-Mbit serial configuration memory device designed for Field Programmable Gate Arrays (FPGAs). It operates at a nominal 3.3V supply voltage with 5.0V tolerant I/O pins and supports a maximum input clock frequency of 33 MHz during FPGA configuration operations. The component utilizes a low-power CMOS Flash process and features in-system programmability via a 2-wire bus. It is housed in a 20-lead Plastic J-leaded Chip Carrier (PLCC) package and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Designed specifically to store configuration programs for SRAM-based FPGAs, enabling simple interface connections without external intelligent controllers.
• Supports In-System Programming (ISP) through a 2-wire serial bus, allowing reconfiguration using standard programmers or dedicated ISP cables.
• Features cascading capability where the Chip Enable Output (CEO) of one device drives the Chip Enable (CE) input of the next, supporting multiple configurations or higher-density arrays.
• Includes page download mode functionality that partitions the address space into four equal pages for storing and retrieving multiple configuration bitstreams from a single device.

Applications

• Configuration of Altera FLEX and APEX devices
• Configuration of Xilinx Spartan, Virtex, XC3000, XC4000, and XC5200 FPGAs
• Configuration of Atmel AT40K and AT94K series devices
• Configuration of Lucent ORCA and Motorola MPA1000 FPGAs

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure compatibility with required package types and lead finishes. Confirm that the intended application environment falls within the specified industrial temperature limits and voltage tolerances. Check for any product change notices regarding package dimensions or material composition updates prior to final design approval.

Selection Notes

Select this component when designing systems requiring non-volatile storage for FPGA configuration data with direct serial interface capabilities. Ensure the target FPGA supports Master Serial mode for automatic configuration loading upon power-up. Consider the cascading feature if the design requires configuring multiple FPGAs or handling larger bitstream files than a single device can accommodate.

Part Context

This part belongs to the AT17F Series of In-System Programmable Configuration PROMs, also known as Configurators. The series provides cost-effective solutions for programming FPGA devices using a simple serial-access procedure. The AT17F080 variant offers double the density of the AT17F040, providing sufficient capacity for more complex FPGA designs while maintaining pin compatibility across the series.

Replacement Considerations

The AT17F040-30JU serves as a lower-density substitute within the same family. Verify pinout compatibility and ensure the reduced memory capacity meets the requirements of the target FPGA configuration bitstream before substituting.
