AT17LV128-10SC

Overview

The AT17LV128-10SC is a serial EEPROM configuration memory component manufactured by Atmel (Microchip). It features a storage density of 131,072 bits organized as 131,072 words by 1 bit. The device operates within a supply voltage range of 4.75V to 5.25V and supports a maximum clock frequency of 10 MHz. It utilizes a 2-wire serial interface for data transfer and offers a typical access time of 75 ns. The component is housed in a 20-pin PLCC package.

Feature Summary

• Designed specifically to store configuration programs for Field Programmable Gate Arrays (FPGAs)
• Supports In-System Programming (ISP) via a simple two-wire bus interface
• Compatible with various FPGA families including Xilinx, Altera, and Atmel devices

Applications

• Configuration of Xilinx XC3000, XC4000, and Spartan FPGAs
• Configuration of Altera FLEX and APEX devices
• Configuration of Lucent ORCA FPGAs
• Configuration of Atmel AT6000 and AT40K FPGAs

Procurement Notes

Verify the specific suffix 'SC' against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing FPGA configuration circuits. Check for RoHS compliance status as older Atmel parts may not meet current environmental standards. Confirm lead times and availability through authorized distributors.

Selection Notes

Select this part when configuring low-density SRAM-based FPGAs requiring serial EEPROM storage. Consider the 10ns speed grade if system timing requires a 10 MHz clock limit. Verify that the 20-pin PLCC package fits the target PCB footprint. Compare against the AT17C128 variant if 3.3V operation is required instead of the standard 5V logic levels supported by the LV series.

Part Context

The AT17LV128 belongs to the Atmel AT17 Series of FPGA Configuration EEPROMs. This family provides cost-effective memory solutions for programming Field Programmable Gate Arrays. The series includes various densities such as 65K, 128K, and 256K bits, packaged in PDIP, SOIC, and PLCC formats to suit different design constraints.

Replacement Considerations

The AT17C128 is a compatible alternative within the same family, offering similar functionality but potentially differing in voltage specifications or package options. Verify pinout compatibility and electrical characteristics before substitution.
