AT17C002-10CC

Overview

The AT17C002-10CC is a 2-megabit serial configuration EEPROM designed for Field Programmable Gate Arrays. It operates at a nominal 5V supply voltage and supports a maximum clock frequency of 15 MHz in commercial applications. The device provides 2,097,152 x 1-bit memory density and utilizes a simple serial interface for FPGA programming. It features an open-collector READY pin to indicate power-up completion and allows programmable reset polarity. The component is housed in an 8-lead Leadless Array Package (LAP) with dimensions of 6 mm x 6 mm x 1 mm.

Feature Summary

• EE reprogrammable serial memory architecture optimized for storing FPGA configuration programs
• In-system programmability via a standard 2-wire bus interface
• Programmable reset polarity logic to match specific FPGA requirements
• System-friendly READY output pin indicating valid power levels during startup

Applications

• Configuration of Xilinx XC3000, XC4000, XC5200, Spartan, and Virtex FPGAs
• Programming Altera FLEX and APEX devices
• Configuration of Atmel AT6000, AT40K, and AT94K series devices
• Daisy-chained cascading configurations for higher-density arrays

Procurement Notes

Verify the package type matches the required footprint, as this part number specifies the 8-lead LAP variant. Confirm that the system design accommodates the 5V nominal supply voltage range specified for the 'C' suffix version. Ensure compatibility with existing ISP tools or programmers if field updates are planned. Check for any specific environmental operating temperature requirements against the commercial grade rating.

Selection Notes

Select this component when a high-density serial configurator is needed for SRAM-based FPGAs requiring a 5V interface. The 8-lead LAP package offers a compact form factor suitable for space-constrained designs. Consider the cascading capability if the target FPGA requires more than 2 megabits of configuration data. Verify that the target FPGA supports Master Serial Mode for direct interfacing without external controllers.

Part Context

This device belongs to the AT17 Series of FPGA Configuration EEPROMs, which serve as cost-effective memory solutions for programming Field Programmable Gate Arrays. The series includes both 5V and 3.3V variants, with the AT17C002 representing the 5V commercial grade option. It functions as a drop-in replacement for older PROM technologies like the XC17/ATT17 series in compatible FPGA designs.

Replacement Considerations

The datasheet identifies the AT17C/LV020 as a predecessor model. Direct replacements within the same family include other packages of the AT17C002 such as the 20-lead PLCC or 44-lead TQFP variants, provided pin compatibility is maintained.
