AT17F16-30JC

Overview

The AT17F16-30JC is a 16-Mbit serial configuration memory device designed for Field Programmable Gate Arrays (FPGAs). It operates at a supply voltage of 3.3V 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 available in multiple package options including the 8-lead LAP, 20-lead PLCC, and 44-lead TQFP.

Feature Summary

• In-system programmability via 2-wire serial bus
• Cascadable read-back capability for multi-device configurations
• Low-power standby mode operation
• Compatibility with various FPGA families

Applications

• Configuration of SRAM-based FPGAs
• Field Programmable Gate Array system reconfiguration
• Cascaded configuration for higher-density arrays

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and operating temperature range. Note that datasheet revision history indicates potential phase-out or migration recommendations for certain legacy packages; ensure the selected variant aligns with current production status and availability requirements.

Selection Notes

Select this component when a cost-effective, serial-access configuration solution is required for SRAM-based FPGAs. Consider the 3.3V supply requirement and 5V tolerant inputs for interface compatibility. Evaluate package constraints such as the 8-lead LAP, 20-lead PLCC, or 44-lead TQFP based on board space and pin count needs.

Part Context

The AT17F16 belongs to the AT17F series of In-System Programmable Configuration PROMs manufactured by Atmel (now Microchip Technology). These configurators provide a simple serial-access procedure to configure one or more FPGA devices directly from power-up without requiring an external intelligent controller.

Replacement Considerations

Customers using the -30JC package may migrate to the AT17F16-30JU according to datasheet revision notes.
