AT17C128-10PI

Overview

The AT17C128-10PI 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 uses a simple serial interface compatible with Master Serial Mode and supports in-system programming via a 2-wire bus. It features programmable reset polarity, write protection, and cascading capability for expanded memory configurations.

Feature Summary

• Designed specifically for storing configuration programs for Field Programmable Gate Arrays (FPGAs)
• Supports in-system programming through a 2-wire serial bus interface
• Features programmable reset polarity and internal write-protection mechanisms
• Allows cascading read-back to support additional configurations or higher-density arrays

Applications

• Configuration of Atmel AT6000 and AT40K FPGAs
• Configuration of Altera FLEX devices
• Configuration of Xilinx XC3000, XC4000, XC5200, and SPARTAN FPGAs
• Configuration of Lucent ORCA and Motorola MPA1000 FPGAs

Procurement Notes

Verify the specific suffix 'PI' corresponds to the Industrial temperature range (-40°C to +85°C) and 8-pin PDIP package as listed in the ordering information. Confirm that the 5V supply voltage requirement aligns with your system design, distinguishing it from the LV (3.3V) variants. Ensure compatibility with standard industry programmers or the specified Atmel programming kit for configuration.

Selection Notes

Select this component when configuring FPGAs requiring 128K bits of non-volatile storage. Choose the PI suffix for industrial temperature environments and through-hole mounting needs. Consider the cascading feature if larger memory capacity is required by connecting multiple units. Verify that the target FPGA supports the Master Serial Mode interface protocol defined for this configurator.

Part Context

This part belongs to the low-density AT17 Series of FPGA Configuration EEPROMs. The series includes 64K, 128K, and 256K density options available in both 5V (AT17C) and 3.3V (AT17LV) versions. The family offers pin-compatible packages including PLCC, SOIC, and PDIP, facilitating easy integration into various hardware designs.

Replacement Considerations

The AT17C128-10NI serves as the commercial temperature variant of this component. For lower voltage applications, the AT17LV128-10PI provides equivalent functionality at 3.3V. Other densities in the series include the AT17C65-10PI and AT17C256-10PI.
