AT17F16-30JI

Overview

The AT17F16-30JI is a 16-Mbit In-System Programmable (ISP) Configuration PROM designed for Field Programmable Gate Arrays. It features a 2-wire serial interface and supports fast download speeds up to 33 MHz. The device operates on a single +3.3V supply with 5V tolerant I/O pins. It utilizes a low-power CMOS FLASH process, offering an endurance of 10,000 write cycles typical. The industrial temperature range spans from -40°C to +85°C.

Feature Summary

• In-System Programmable via 2-wire bus
• Compatible with various FPGA families including Xilinx and Altera
• Cascadable read-back capability for multi-device configurations
• Low-power standby mode operation

Applications

• Configuration memory for SRAM-based FPGAs
• Field Programmable Gate Array configuration programs
• System reconfiguration using 4-bit stream files
• Emulation of Atmel AT24CXXX Serial EEPROMs

Procurement Notes

Verify the specific package type required, as the datasheet indicates migration paths for older packages like PLCC and TQFP. Confirm that the industrial temperature rating (-40°C to +85°C) matches the application environment. Ensure programming equipment supports the 2-wire serial protocol or ISP cable requirements specified in the documentation.

Selection Notes

Select this component when a cost-effective, serial configuration solution for FPGAs is needed. It is suitable for designs requiring compatibility with legacy Atmel, Altera, Lucent, Motorola, and Xilinx devices. Consider cascading capabilities if the target FPGA array exceeds the single device capacity. Verify power supply constraints align with the 3.3V nominal requirement.

Part Context

The AT17F Series serves as configurators for SRAM-based FPGAs, providing a simple serial-access procedure to configure one or more devices. This series includes options in 8-lead LAP, 20-lead PLCC, and 44-lead TQFP packages. The AT17F16 specifically offers 16 Mbits of storage, partitionable into pages for multiple bitstreams.

Replacement Considerations

Customers migrating from AT17F16-30JC or AT17F16-30JI packages may consider the AT17F16-30JU as a replacement option according to the datasheet revision history.
