AT17C010A-10QC

Overview

The AT17C010A-10QC is a 1-Mbit serial EEPROM configurator designed for Altera FLEX devices. It operates at 5V nominal with an industrial temperature range of -40°C to +85°C. The device uses a 32-lead TQFP package and features a simple serial interface for FPGA configuration. It supports cascading for higher-density arrays, includes a system-friendly READY pin, and allows programmable reset polarity.

Feature Summary

• Provides cost-effective configuration memory for programming Altera FLEX field programmable gate arrays via a simple serial-access procedure.
• Supports cascading read-back capabilities to enable configurations for multiple smaller FPGAs or future higher-density arrays.
• Features a system-friendly READY pin that indicates the power-on reset status to simplify system power-up considerations.

Applications

• Configuring Altera FLEX field programmable gate arrays
• Storing configuration programs for serial access to SRAM FPGAs
• Cascaded multi-device FPGA configuration systems

Procurement Notes

Verify the specific ordering code matches the required voltage and package. Confirm the suffix corresponds to the 32-lead TQFP variant. Ensure the industrial temperature rating aligns with operational requirements. Cross-reference the datasheet revision for accurate electrical characteristics.

Selection Notes

Select this component when configuring Altera FLEX devices requiring 1-Mbit storage capacity. Choose the industrial grade version for environments operating between -40°C and +85°C. Consider the TQFP package for surface-mount applications requiring a compact footprint. Verify compatibility with the target FPGA's serial protocol requirements.

Part Context

This part belongs to the AT17A Series family of FPGA Configuration EEPROMs manufactured by Atmel. The series includes 512-Kbit and 1-Mbit variants available in various packages. These devices are specifically engineered to store configuration data for Altera FLEX devices using a low-power CMOS EEPROM process.

Replacement Considerations

The AT17LV010A-10QC serves as the 3.3V equivalent within the same series. For 512-Kbit capacity replacements, consider the AT17C512A-10QC. Verify voltage compatibility and package dimensions before substitution.

FAQ

How does the device handle cascading for larger configurations?

Multiple AT17A Series devices can be serially linked. The first device drives the nCASC pin Low upon finishing its data, which activates the subsequent device in the chain.

What is the function of the READY pin?

The READY pin is an open-collector indicator driven Low during the power-on reset cycle and released (tri-stated) when the cycle is complete.
