AT17F16-30TQC

Overview

The AT17F16-30TQC is a 16-Mbit serial configuration PROM designed for Field Programmable Gate Arrays (FPGAs). It operates on a single +3.3V supply with 5V tolerant I/O pins and supports fast serial download speeds up to 33 MHz. The device features in-system programmability via a 2-wire bus, low-power CMOS FLASH process technology, and an endurance rating of 10,000 write cycles typical. It is housed in a 44-lead Thin Plastic Quad Flat Package (TQFP) suitable for commercial temperature ranges.

Feature Summary

• In-system programmability via 2-wire serial bus
• Compatible with major FPGA families including Xilinx and Altera
• Supports cascading for higher-density configurations
• Emulates Atmel AT24CXXX serial EEPROMs

Applications

• Configuration memory for SRAM-based FPGAs
• Field Programmable Gate Array system reconfiguration
• Cascaded read-back support for additional configurations

Procurement Notes

Verify the package type matches the required footprint, as the AT17F16 series is available in multiple packages including LAP, PLCC, and TQFP. Confirm that the operating temperature range aligns with the commercial specification (-0°C to +70°C), as industrial variants exist. Ensure programming equipment compatibility with the 2-wire serial interface or third-party programmers before procurement.

Selection Notes

Select this component when a cost-effective, serial-access configuration solution is needed for SRAM-based FPGAs. Consider the 44-lead TQFP package if space constraints allow for larger footprints compared to the 8-lead LAP option. Verify that the 3.3V supply voltage and 5V tolerant inputs match the target FPGA's logic levels. Check if the 16-Mbit capacity is sufficient for the specific bitstream requirements.

Part Context

The AT17F16 belongs to the AT17F Series of In-System Programmable Configuration PROMs originally manufactured by Atmel Corporation. These devices are designed to provide easy-to-use configuration memory for various FPGA architectures. The series supports simple serial interfaces and is compatible with industry-standard programmers, facilitating straightforward integration into FPGA design flows.

Replacement Considerations

Customers may migrate to the AT17F32-BJU for increased memory density. For existing -30JC or -30JI packages, migration to the AT17F16-30JU is suggested.
