AT17F16A-30JC

Overview

The AT17F16A-30JC is a 16-Mbit In-System Programmable (ISP) Configuration PROM designed for Field Programmable Gate Arrays. It utilizes a low-power CMOS FLASH process and operates at a supply voltage of 3.3V with 5V tolerant I/O pins. The device supports serial download speeds up to 33 MHz and features an endurance of 10,000 write cycles typical. It is available in a 20-lead Plastic J-leaded Chip Carrier (PLCC) package.

Feature Summary

• Supports In-System Programming via a 2-wire bus interface
• Enables cascading for additional configurations or higher-density arrays
• Provides emulation of serial EEPROMs for simplified system integration

Applications

• Configuration memory for Altera FLEX, Excalibur, Stratix, Cyclone, and APEX devices
• Configuration storage for Atmel AT40K and AT94K devices
• Single-device bitstream storage allowing simple system reconfiguration

Procurement Notes

Verify the specific ordering suffix 'JC' corresponds to the 20-lead PLCC package and commercial temperature range as defined in the official datasheet. Confirm that the component meets the required lead and halide-free specifications if applicable to your manufacturing standards. Ensure compatibility with the intended FPGA master serial mode before procurement.

Selection Notes

Select this component when a non-volatile configuration source is required for SRAM-based FPGAs. It is suitable for designs needing independent control of the configuration process without an external intelligent controller. Consider its compatibility with industry-standard programmers or ISP cables for flexible programming options.

Part Context

This part belongs to the AT17FxxA series of configurators, which provide cost-effective configuration memory solutions. The series includes variants with different capacities and packages, such as the 8-lead LAP and 20-lead PLCC options. These devices are engineered to simplify the configuration of complex programmable logic devices.

Replacement Considerations

Compatible substitutes include other parts within the AT17FxxA series, such as the AT17F16A-30JI for industrial temperature ranges or the AT17F080A for smaller capacity requirements. Verify pinout and electrical characteristics against the target application before substitution.

FAQ

How does the device handle multiple configuration bitstreams?

The device can store four bitstream files using page select inputs (PAGESEL0 and PAGESEL1) when paging is enabled, allowing for simple system reconfiguration.

What is the function of the nCASC output pin?

The nCASC output goes Low when the internal address counter reaches its maximum value, enabling the daisy-chaining of multiple configurator devices for larger memory requirements.
