AT17LV128-10PI

Overview

The AT17LV128-10PI is a 128-Kbit serial EEPROM configurator designed for FPGA configuration. It operates on both 3.3V and 5.0V supplies, supporting commercial (0°C to +70°C) and industrial (-40°C to +85°C) temperature ranges. The device features a simple two-wire serial interface for in-system programming and direct connection to FPGA control signals. It includes programmable reset polarity, write protection mechanisms, and cascading capabilities via the CEO output pin.

Feature Summary

• Supports dual voltage operation at 3.3V and 5.0V for broad system compatibility
• Enables in-system programming via a standard two-wire serial bus
• Allows user-programmable logic polarity for reset and output enable functions
• Provides cascading support through a dedicated chip enable output pin

Applications

• Configuration memory storage for Xilinx XC3000, XC4000, and Spartan FPGAs
• Configuration memory storage for Altera FLEX and APEX devices
• Configuration memory storage for Atmel AT6000, AT40K, and AT94K devices
• Daisy-chained configurations for multiple FPGAs or high-density arrays

Procurement Notes

Verify that the specific ordering suffix matches the required package type and operating temperature range. Confirm whether the application requires lead-free compliance, as standard versions may differ from green package options. Ensure the design accounts for the specific pinout differences between the 8-lead and 20-lead variants within the series.

Selection Notes

Select this component when a cost-effective serial solution is needed for SRAM-based FPGA configuration. Consider the 8-lead PDIP package for through-hole applications or the 8-lead LAP/SOIC for surface mount needs. Verify that the target FPGA supports master serial mode and that the available memory density meets the bitstream requirements.

Part Context

This part belongs to the AT17LV series of FPGA Configuration EE PROMs manufactured by Microchip Technology. The series provides various densities ranging from 65-Kbit to 4-Mbit. The AT17LV128 specifically offers 128-Kbit capacity, suitable for smaller FPGA designs requiring non-volatile configuration storage with low power consumption.

Replacement Considerations

Customers using -10SC or -10SI packages may migrate to the AT17LVXXX-10SU. For -10TQC or -10TQI packages, migration to the AT17LVXXX-10TQU is supported. Verify pin compatibility and electrical characteristics before substituting.
