AT17F16A-30JU

Overview

The AT17F16A-30JU is a 16-Mbit serial configuration PROM designed for Field Programmable Gate Arrays. 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 and includes low-power standby mode capabilities. It is housed in a 20-lead PLCC package and supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Supports In-System Programming (ISP) via a 2-wire serial bus interface
• Provides simple serial access for configuring SRAM-based FPGA devices
• Features cascading capability through nCASC output for multi-device configurations
• Includes page select inputs to partition memory for multiple bitstream storage

Applications

• Configuration of Altera FLEX, Excalibur, Stratix, Cyclone, and APEX devices
• Configuration of Atmel AT40K and AT94K devices
• Daisy-chain configuration setups requiring additional memory density
• Systems requiring simple reconfiguration using stored bitstream files

Procurement Notes

Verify the component originates from authorized Microchip or Atmel distribution channels due to potential legacy status. Confirm the specific suffix matches the 20-lead PLCC package requirement. Ensure compatibility with existing FPGA master serial mode requirements before procurement. Check for RoHS compliance documentation if required by local regulations.

Selection Notes

Select this component when a 16-Mbit capacity is required for FPGA configuration. It is suitable for designs needing 5V tolerant interfaces while operating at 3.3V. Consider its cascading ability if larger configuration spaces are needed. Verify that the target FPGA supports the serial master mode compatible with this configurator series.
