AT17C020-10JI

Overview

The AT17C020-10JI is a 2-megabit FPGA Configuration EEPROM (Configurator) manufactured by Microchip Technology. It provides non-volatile memory for storing configuration programs for Field Programmable Gate Arrays. The device operates at a nominal 5V supply voltage and supports an industrial temperature range of -40°C to +85°C. It features a 20-pin Plastic J-leaded Chip Carrier (PLCC) package with a serial interface compatible with Master Serial Mode. Key specifications include a maximum input clock frequency of 12.5 MHz, low-power standby mode, and programmable reset polarity.

Feature Summary

• EE reprogrammable serial memory designed specifically for storing configuration programs for FPGAs
• In-system programmable via a 2-wire bus using industry-standard programmers
• Supports cascading read-back capabilities for additional configurations or higher-density arrays
• Includes a system-friendly READY pin to indicate power-up status and ensure reliable system initialization

Applications

• Configuration of Atmel AT6000 and AT40K FPGAs
• Configuration of Altera FLEX devices
• Configuration of Xilinx Spartan and Virtex FPGAs

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm the exact operating temperature range and voltage requirements. Ensure that the procurement source provides valid traceability for the component. Confirm compatibility with the target FPGA's Master Serial Mode interface requirements before finalizing orders.

Selection Notes

Select this component when a high-density, cost-effective solution is required for configuring SRAM-based FPGAs. The industrial temperature rating makes it suitable for broader environmental applications compared to commercial variants. Consider the PLCC package availability and pin compatibility with existing board layouts designed for the AT17 series family.

Part Context

This part belongs to the AT17 Series of FPGA Configuration EEPROMs, which are designed to provide easy-to-use configuration memory. The series includes both 5V (AT17C) and 3.3V (AT17LV) versions. The AT17C020-10JI specifically denotes the 5V industrial grade variant within this product line, offering 2Mb of storage capacity in a standard 20-lead PLCC package.

Replacement Considerations

The AT17LV020-10JI serves as a direct pin-compatible alternative within the same package but operates at a 3.3V supply voltage instead of 5V. Other members of the AT17 family may offer different memory densities or voltage options while maintaining physical compatibility.
