AT17F16-30JU

Overview

The AT17F16-30JU is a 16-Mbit serial configuration flash memory designed for Field Programmable Gate Arrays (FPGAs). It operates at a supply voltage of 2.97V to 3.63V and supports industrial temperature ranges from -40°C to +85°C. The device features fast serial download speeds up to 33 MHz and includes In-System Programming (ISP) capabilities via a 2-wire bus. It is available in a 20-lead PLCC package.

Feature Summary

• In-System Programmable (ISP) capability via a 2-wire serial bus
• Compatible with major FPGA families including Altera, Xilinx, and Atmel devices
• Supports cascading read-back for higher-density array configurations
• Features low-power CMOS FLASH process with standby mode

Applications

• Configuration storage for SRAM-based FPGAs
• Field Programmable Gate Array system reconfiguration
• Cascaded configuration for multi-device FPGA arrays

Procurement Notes

Verify the manufacturer origin as the datasheet identifies Atmel Corporation, while the model prefix suggests Microchip Technology acquisition. Confirm the specific package type matches the required PCB footprint, as the series offers multiple options including LAP and TQFP. Ensure the industrial temperature rating aligns with environmental requirements.

Selection Notes

Select this component when a 16-Mbit capacity is required for FPGA configuration. Consider the 20-lead PLCC package if through-hole mounting is necessary. Verify compatibility with the target FPGA's master serial mode interface. Check if ISP functionality is needed for field updates.

Part Context

This part belongs to the AT17F Series of In-System Programmable Configuration PROMs. These configurators provide cost-effective memory solutions for loading programs into FPGAs upon power-up or on command. The series supports various packages to accommodate different design constraints.

Replacement Considerations

Customers migrating from older AT17F16 variants such as -30JC or -30JI may consider the AT17F16-30JU as a compatible replacement option.
