AT17F16-30TQI

Overview

The AT17F16-30TQI is a 16-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 features fast download speeds up to 33 MHz. It includes low-power standby modes, 10,000 write cycle endurance, and compatibility with various FPGA masters.

Feature Summary

• In-system programmable via 2-wire bus
• Compatible with multiple FPGA families
• Low-power CMOS FLASH process
• Cascadable read-back support

Applications

• Configuration of SRAM-based FPGAs
• Field Programmable Gate Array configurators
• System reconfiguration memory

Procurement Notes

Verify the specific package type matches the design requirements, as the AT17F series is available in LAP, PLCC, and TQFP formats. Confirm that the industrial temperature rating (-40°C to +85°C) aligns with the operational environment. Ensure programming tools are compatible with the 2-wire serial interface for in-system updates.

Selection Notes

Select this component when a cost-effective, serial configuration solution for FPGAs is required. The 44-lead TQFP package offers a compact footprint suitable for dense PCB layouts. Consider the 33 MHz maximum clock speed for high-throughput configuration needs and verify compatibility with the target FPGA's master serial mode.

Part Context

The AT17F16-30TQI belongs to the AT17F series of In-System Programmable Configuration PROMs manufactured by Atmel (now Microchip Technology). This series provides non-volatile memory solutions specifically tailored for initializing FPGA devices upon power-up or during runtime reconfiguration events.

Replacement Considerations

Customers may migrate to the AT17F32-BJU for higher density requirements. For pin-compatible replacements within the same package family, consult the manufacturer's migration guide for equivalent or enhanced performance options.
