AT17C128-10CI

Overview

The AT17C128-10CI is a serial configuration memory device manufactured by Microchip Technology, formerly Atmel. It features a density of 131,072 bits organized as 128K x 1. The component operates with a maximum clock frequency of 12.5 MHz and has a typical access time of 50 ns. It utilizes synchronous operation modes and is housed in an 8-pin SOIC package. The device is designed for CMOS technology and serves as non-volatile storage for system configuration data.

Feature Summary

• Provides serial configuration memory for programmable logic devices
• Supports synchronous operation modes for reliable data transfer
• Includes hardware and software data protection mechanisms

Applications

• Configuration PROM for Field Programmable Gate Arrays (FPGAs)
• System configuration storage in embedded designs
• Non-volatile memory for industrial control systems

Procurement Notes

Verify the specific suffix 'CI' against official Microchip documentation to confirm temperature range and package variations. Confirm RoHS compliance status as historical records may vary. Ensure the source document explicitly lists this part number to avoid confusion with similar AT17 series variants. Check for any obsolescence notices or lifecycle changes before procurement planning.

Selection Notes

Select this component when a 128K-bit serial configuration memory is required for FPGA or CPLD initialization. Verify that the 50 ns access time and 12.5 MHz clock speed meet the target system's timing requirements. Ensure the 8-pin SOIC package fits the available PCB footprint. Compare against newer AT17LV or AT25 series if lower voltage operation or updated manufacturing processes are needed.

Part Context

This part belongs to the AT17C/AT17LV family of serial EEPROMs designed specifically for configuration applications. These devices store bitstream data used to configure programmable logic devices upon power-up. The AT17C128 variant represents a higher density option within the legacy Atmel portfolio, now managed by Microchip Technology.
