CY7C1021B-15VXC

Memory IC Overview

The CY7C1021B-15VXC is a 1-Mbit (64K x 16) asynchronous static RAM manufactured by Infineon Technologies. It features a maximum access time of 15 ns and operates on a single 5 V power supply within the range of 4.5 V to 5.5 V. The device utilizes CMOS technology for high-speed performance and low active power consumption, with a maximum operating current of 130 mA in commercial and industrial ranges. It includes automatic power-down when deselected and independent control of upper and lower byte data lines.

Memory IC Feature Summary

• Features an automatic power-down mode that significantly reduces power consumption when the device is deselected.
• Provides independent control of upper and lower bits via dedicated Byte Write Select inputs.
• Utilizes CMOS technology to achieve high speed combined with low active power consumption.

Memory IC Applications

• High-performance parallel memory systems requiring fast asynchronous access
• Industrial applications operating within extended temperature ranges
• Automotive electronic systems requiring robust environmental tolerance

Memory IC Procurement Notes

Verify the specific ordering suffix 'VXC' confirms the 44-pin SOJ package type and Pb-free status as documented in the official datasheet. Confirm the '-15' designation aligns with the required 15 ns access time specifications. Ensure compatibility with standard 5 V logic levels and check for any automotive or industrial qualification requirements if applicable to the target environment.

Memory IC Selection Notes

Select this component for designs requiring a 1-Mbit capacity with a 16-bit word width. The 15 ns access speed suits general-purpose high-speed buffering needs. Consider the 44-pin SOJ package constraints for PCB layout. Evaluate the 130 mA maximum operating current against system power budgets and ensure adequate thermal management for the specified ambient temperature range.

Memory IC Part Context

This part belongs to the CY7C1021B family of 1-Mbit Static RAMs. The family offers variations in speed grades (-12, -15) and packages (TSOP II, SOJ). The CY7C1021B series is designed for applications needing reliable volatile memory storage with fast read/write cycles and low standby power characteristics typical of CMOS SRAM architectures.

Memory IC Replacement Considerations

CY7C1021B-15VXI serves as a direct equivalent within the same package and speed grade but may differ in lead composition. CY7C1021B-15ZC provides the same electrical specifications in a TSOP Type II package, requiring footprint adaptation.
