AT17C020-10JC

Overview

The AT17C020-10JC is a 2M x 1 bit serial configuration EEPROM designed for Field Programmable Gate Arrays. It operates at 5V nominal with a commercial temperature range of 0°C to 70°C. The device provides 2,097,152 bits of non-volatile memory in a 20-lead PLCC package. It supports in-system programming via a 2-wire bus and features a system-friendly READY pin for power-up synchronization.

Feature Summary

• EE reprogrammable serial memory architecture optimized for FPGA configuration programs
• In-system programmability enabled through a dedicated 2-wire serial bus interface
• Programmable reset polarity allowing flexible integration with various FPGA control signals
• System-ready output pin indicating valid power levels during the initialization cycle

Applications

• Configuration storage for Atmel AT6000 and AT40K FPGAs
• Configuration storage for Altera FLEX devices
• Configuration storage for Xilinx Spartan and Virtex FPGAs
• Configuration storage for Lucent ORCA FPGAs

Procurement Notes

Verify that the specific ordering suffix matches the required voltage and temperature grade. Confirm the package type corresponds to the design footprint. Ensure the component meets the necessary environmental standards for the intended deployment environment before finalizing procurement orders.

Selection Notes

Select this component when a high-density serial configurator is required for SRAM-based FPGAs. Consider the 5V supply requirement and commercial temperature range. Evaluate compatibility with existing FPGA master serial mode interfaces and verify support for cascading if multiple configuration memories are needed.

Part Context

This part belongs to the AT17 Series of FPGA Configuration EEPROMs manufactured by Microchip Technology (formerly Atmel). The series utilizes a low-power CMOS EEPROM process and is available in multiple packages including PLCC. The family supports emulation of standard serial EEPROM protocols for simplified system integration.

Replacement Considerations

AT17LV020-10JC offers equivalent functionality with a 3.3V operating voltage.
