AT17LV020-10JI

Configuration PROMs For FPGAs Overview

The AT17LV020-10JI is a 2-megabit (2,097,152 x 1 bit) serial EEPROM designed for FPGA configuration. It operates within a supply voltage range of 3.0V to 3.6V and supports an industrial temperature range of -40°C to +85°C. The device utilizes a simple serial interface compatible with SRAM FPGAs in Master Serial Mode. Key electrical characteristics include a maximum input clock frequency of 12.5 MHz in commercial applications and 7.5 MHz in industrial environments. It features low-power standby mode consumption below 0.2 mA and includes a system-friendly READY pin for power-up indication.

Configuration PROMs For FPGAs Feature Summary

• EE reprogrammable serial memory architecture specifically engineered for storing configuration programs for Field Programmable Gate Arrays.
• Supports in-system programming via a 2-wire bus interface when the serial enable pin is asserted.
• Features programmable reset polarity allowing selection between active high or active low logic states.
• Includes a cascading capability through the CEO output to support multiple devices or higher-density arrays.

Configuration PROMs For FPGAs Applications

• Configuration of Atmel AT6000 and AT40K series FPGAs
• Configuration of Altera FLEX and ORCA series FPGAs
• Configuration of Xilinx XC3000, XC4000, XC5200, Spartan, and Virtex series FPGAs

Configuration PROMs For FPGAs Procurement Notes

Verify that the specific ordering suffix corresponds to the required operating temperature range and package type. Confirm that the application environment strictly adheres to the specified 3.0V to 3.6V supply voltage limits for the LV variant. Ensure compatibility with the target FPGA's master serial mode requirements before procurement.

Configuration PROMs For FPGAs Selection Notes

Select this component for designs requiring non-volatile storage of FPGA bitstreams with low power consumption. The industrial grade (-40°C to +85°C) makes it suitable for broader environmental conditions compared to commercial variants. Consider the 20-lead PLCC package constraints and ensure the PCB layout accommodates the specific pinout and decoupling capacitor recommendations.

Configuration PROMs For FPGAs Part Context

This part belongs to the AT17 Series of high-density FPGA Configuration EEPROMs manufactured by Microchip Technology (formerly Atmel). The series provides cost-effective configurators for various FPGA families. The 'LV' designation indicates the 3.3V operation version, distinct from the standard 5V 'C' version. The 'JI' suffix identifies the industrial temperature range and 20-lead PLCC package.

Configuration PROMs For FPGAs Replacement Considerations

AT17C020-10JI serves as a pin-compatible alternative but requires a 5V supply instead of 3.3V. Other members of the AT17 family may offer different memory densities or package options while maintaining functional compatibility.
