AT17LV256-10CC

Overview

The AT17LV256-10CC is a 256-Kbit serial EEPROM designed for FPGA configuration. It supports both 3.3V and 5.0V operating voltages and features in-system programmability via a two-wire bus. The device operates within a commercial temperature range of 0°C to +70°C and utilizes an 8-lead Leadless Array Package (LAP).

Feature Summary

• Designed to store configuration programs for Field Programmable Gate Arrays (FPGAs)
• Supports In-System Programming (ISP) via a Two-Wire Bus interface
• Compatible with SRAM FPGAs from major manufacturers including Xilinx, Altera, and Atmel
• Features low-power CMOS EEPROM process with standby mode capability

Applications

• Configuration memory for Xilinx XC3000, XC4000, and Spartan devices
• Configuration memory for Altera FLEX and APEX devices
• Configuration memory for Atmel AT40K and AT94K devices
• Cascaded read-back configurations for higher-density arrays

Procurement Notes

Verify the package type corresponds to the 8-lead LAP (8CN4) designation. Confirm the suffix indicates the commercial temperature range (0°C to +70°C). Ensure the ordering code matches the specific voltage requirements of the target system.

Selection Notes

Select this component when a cost-effective serial configuration memory is required for SRAM-based FPGAs. It is suitable for applications supporting both 3.3V and 5.0V systems. Consider cascading capabilities if larger configuration spaces are needed beyond the single-device capacity.

Part Context

This part belongs to the AT17LV series of FPGA Configuration EEPROMs. These devices provide a simple serial-access procedure to configure one or more FPGA devices. The series includes various densities and packages to support different FPGA families and design constraints.

Replacement Considerations

Customers may migrate to AT17LVXXX-10CU for fully green package options while maintaining industrial temperature ranges.
