AT17C128-10SC

Overview

The AT17C128-10SC is a 131,072 x 1-bit serial EEPROM designed for FPGA configuration. It operates at 5V nominal with a supply range of 4.5V to 5.5V and supports clock frequencies up to 12.5 MHz in standalone mode. The device features an 8-pin SOIC package and includes programmable reset polarity, standby mode, and write protection. It provides compatibility with various FPGA families and supports cascading for expanded memory configurations.

Feature Summary

• Designed specifically for storing configuration programs for Field Programmable Gate Arrays (FPGAs)
• Features a simple serial-access procedure compatible with FPGA Master Serial Mode
• Includes programmable reset polarity and hardware/software data protection mechanisms

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 suffix 'SC' corresponds to the 8-lead SOIC package and commercial temperature range as defined in the ordering information. Confirm that the design requires 5V operation, as this part is distinct from the LV series. Ensure programming tools support the 2-wire serial bus interface required for entering programming mode via SER_EN.

Selection Notes

Select this component when a 128K-bit capacity is required for FPGA configuration in a compact 8-pin footprint. Consider the AT17LV128 variant if the system operates at 3.3V. Verify that the target FPGA supports the serial master mode interface and that the maximum clock frequency requirements align with the 12.5 MHz specification.

Part Context

This device belongs to the AT17 Series low-density FPGA Configuration EEPROMs. The family includes 64K, 128K, and 256K density options available in both 5V (AT17C) and 3.3V (AT17LV) versions. These configurators are engineered to provide cost-effective and easy-to-use memory solutions for programming field-programmable gate arrays.

Replacement Considerations

AT17LV128-10SC: Equivalent 128K-bit EEPROM operating at 3.3V instead of 5V. AT17C128-10SI: Same electrical specifications but housed in a 20-lead SOIC package.
