AT17C128-10SI

Overview

The AT17C128-10SI is a 131,072 x 1-bit serial EEPROM designed for FPGA configuration. It operates at 5V nominal with an industrial temperature range of -40°C to +85°C. The device features a simple serial interface compatible with FPGA Master Serial Mode and supports in-system programming via a 2-wire bus. It is available in a 20-lead SOIC package.

Feature Summary

• Designed specifically to store configuration programs for Field Programmable Gate Arrays (FPGAs).
• Supports in-system programming through a 2-wire serial bus interface.
• Features programmable reset polarity to accommodate different system requirements.

Applications

• Configuration memory for Atmel AT6000 and AT40K FPGAs.
• Configuration memory for Altera FLEX devices.
• Configuration memory for Xilinx XC3000, XC4000, and SPARTAN FPGAs.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and operating temperature range. Ensure compatibility with the target FPGA's configuration mode pins. Confirm that the 5V supply voltage aligns with the system design requirements before procurement.

Selection Notes

Select this component when a 128K-bit capacity is required for FPGA configuration. It is suitable for systems requiring industrial temperature stability. Consider cascading capabilities if larger memory sizes are needed for multiple or high-density FPGAs.

Part Context

This part belongs to the low-density AT17 Series of FPGA Configuration EEPROMs. The series includes 64K, 128K, and 256K variants. The 'C' designation indicates 5V operation, while 'LV' denotes 3.3V versions. The 'SI' suffix specifies the 20-lead SOIC package and industrial temperature range.
