AT17F080-30TQI

Overview

The AT17F080-30TQI is an 8-Mbit serial configuration memory device designed for Field Programmable Gate Arrays (FPGAs). It operates within a supply voltage range of 2.97 V to 3.63 V and supports industrial temperature ranges from -40°C to +85°C. The component utilizes a low-power CMOS Flash process and features a simple serial interface compatible with FPGA Master Serial modes. It offers fast download speeds up to 33 MHz and includes in-system programmability via a 2-wire bus.

Feature Summary

• Supports In-System Programming (ISP) through a 2-wire serial bus interface
• Enables cascading capabilities for configuring multiple FPGAs or higher-density arrays
• Provides page-select functionality to store and retrieve multiple configuration bitstreams
• Compatible with various SRAM-based FPGA architectures including Xilinx and Altera devices

Applications

• Configuration of Xilinx XC3000, XC4000, and Virtex series FPGAs
• Configuration of Altera FLEX and APEX series FPGAs
• Configuration of Lucent ORCA and Motorola MPA1000 FPGAs
• Daisy-chain configurations requiring expanded memory capacity

Procurement Notes

Verify the specific package type corresponds to the 44-lead Thin Plastic Quad Flat Package (TQFP) indicated by the suffix TQ. Confirm that the industrial temperature grade (-40°C to +85°C) matches the design requirements. Ensure programming equipment supports the 2-wire serial protocol for ISP operations. Check for end-of-life status as this component originates from legacy Atmel product lines now managed under Microchip Technology.

Selection Notes

Select this component when an 8-Mbit capacity is required for FPGA configuration. The TQFP package is suitable for surface-mount applications requiring a compact footprint. Consider the 33 MHz maximum clock speed for high-speed configuration needs. Verify compatibility with the target FPGA's master serial mode requirements before integration into the system design.

Part Context

This part belongs to the AT17F series of In-System Programmable Configuration PROMs. Originally developed by Atmel Corporation, these devices are now part of Microchip Technology's portfolio. The series provides cost-effective solutions for storing configuration programs for SRAM-based FPGAs, offering flexibility through serial interfaces and support for complex multi-device configurations.

Replacement Considerations

AT17F080-30BJI: Same 8-Mbit capacity and industrial temperature range but housed in a 44-lead PLCC package instead of TQFP.
