AT17F16A-30CU

Overview

The AT17F16A-30CU is a 16-Mbit FPGA configuration memory device manufactured by Microchip Technology (formerly Atmel). It operates at a nominal 3.3V supply voltage with 5.0V tolerant I/O pins and supports industrial temperature ranges from -40°C to +85°C. The component features a maximum serial download speed of 33MHz, typical endurance of 10,000 write cycles, and standby current consumption under 3mA. It is housed in an 8-pad Leadless Array Package (LAP) with dimensions of 6.00mm x 6.00mm x 1.04mm.

Feature Summary

• Supports In-System Programming (ISP) via a 2-wire bus for flexible field updates
• Enables system reconfiguration through four independent bitstream pages within a single device
• Provides direct interface compatibility with SRAM-based FPGAs without external controllers
• Features cascading capability to expand configuration capacity for high-density arrays

Applications

• Configuration of Altera Stratix, Cyclone, and APEX series FPGAs
• Configuration of Xilinx Field Programmable Gate Arrays
• Configuration of Atmel AT40K and AT94K devices
• Multi-bitstream storage for systems requiring simple hardware reconfiguration

Procurement Notes

Verify the specific package variant required, as the AT17F16A family includes both 8-pad LAP and 20-lead PLCC options. Confirm that the Industrial temperature grade (-40°C to +85°C) aligns with your environmental specifications. Ensure programming equipment compatibility with the 2-wire ISP mode if field updates are planned.

Selection Notes

Select this component when designing systems requiring non-volatile storage for FPGA configuration data. It is suitable for applications needing multiple configuration profiles stored on-chip. Consider the 8-pad LAP package for space-constrained designs or the PLCC option for legacy socketed implementations.

Part Context

This part belongs to the AT17FxxxA series of Serial Configuration PROMs designed specifically for FPGA configurators. These devices emulate standard serial EEPROM interfaces while providing the density and speed necessary for modern FPGA initialization. The series allows designers to replace complex parallel configuration schemes with simplified serial connections.
