CY7C1021DV33-10ZSXI

Memory IC Overview

The CY7C1021DV33-10ZSXI is a 1-Mbit (64 K × 16) static RAM manufactured by Infineon Technologies. It operates within a voltage range of 3 V to 3.6 V and supports an industrial temperature range from -40 °C to +85 °C. The device features a maximum access time of 10 ns, with a maximum operating current of 60 mA and a standby current of 3 mA. It utilizes a parallel interface and is housed in a 44-pin TSOP II package.

Memory IC Feature Summary

• Features automatic power-down when deselected to reduce active power consumption.
• Provides independent control of upper and lower bits via Byte Low Enable and Byte High Enable inputs.
• Supports data retention at a minimum supply voltage of 2.0 V.

Memory IC Applications

• Industrial embedded systems requiring high-speed volatile memory
• Automotive-A applications compatible with standard SRAM interfaces
• General-purpose digital logic buffering and cache storage

Memory IC Procurement Notes

Verify the specific ordering suffix 'ZS' corresponds to the 44-pin TSOP Type II package configuration. Confirm that the '-10' speed bin meets the required 10 ns access time for your system timing constraints. Ensure the component is sourced as Pb-free and complies with RoHS standards. Check for any discontinuation notices or lifecycle status updates directly from the manufacturer before finalizing procurement plans.

Memory IC Selection Notes

Select this component if your design requires a 64K x 16 organization with a 10 ns access speed. It is suitable for applications needing independent byte-level write control. Consider the 44-pin TSOP II package dimensions for PCB layout compatibility. Verify that the 3.3 V nominal supply voltage aligns with your system's power rails and that the industrial temperature range satisfies environmental requirements.

Memory IC Part Context

Memory IC FAQ

How does the device handle deselection?

When deselected (CE HIGH), the outputs enter a high-impedance state and the device automatically enters a power-down mode to minimize standby current.

What is the data retention capability?

The device retains data even when the supply voltage drops to a minimum of 2.0 V, ensuring data integrity during power transitions.
