AT17LV256-10JC

Overview

The AT17LV256-10JC is a 256-Kbit serial EEPROM designed for FPGA configuration. It supports both 3.3V and 5.0V operating voltages and operates within an industrial temperature range of -40°C to +85°C. The device utilizes a simple two-wire bus interface for in-system programming and direct connection to SRAM FPGAs. It features programmable reset polarity, write protection mechanisms, and cascading capabilities via the CEO output pin.

Feature Summary

• Supports in-system programming via a two-wire serial bus
• Enables direct interface with SRAM-based FPGA devices
• Allows user-programmable reset logic polarity
• Provides cascading support through the Chip Enable Output (CEO) pin

Applications

• Configuration memory for Xilinx XC3000, XC4000, and Spartan FPGAs
• Configuration storage for Altera FLEX and APEX devices
• Configuration memory for Atmel AT40K and AT94K series devices
• Cascaded configuration setups for high-density FPGA arrays

Procurement Notes

Verify that the ordering suffix 'JC' corresponds to the 20-lead PLCC package and Industrial temperature rating (-40°C to +85°C). Confirm compatibility with the specific FPGA master serial mode requirements. Ensure voltage supply levels match the 3.3V or 5.0V specifications defined in the datasheet DC characteristics.

Selection Notes

Select this component when a 256-Kbit capacity is required for FPGA configuration. Choose the Industrial temperature grade if operation below 0°C is necessary. Verify that the target FPGA supports the Master Serial mode compatible with the AT17LV series timing parameters.

Part Context

This part belongs to the AT17LV series of FPGA Configuration EEPROMs manufactured by Microchip Technology (formerly Atmel). The series provides cost-effective configuration solutions for various field-programmable gate arrays. The AT17LV256 variant specifically offers 256-Kbit storage capacity suitable for medium-complexity FPGA designs.
