CY7C166-20VC

Memory IC Overview

The CY7C166-20VC is a standard static random-access memory (SRAM) integrated circuit manufactured by Cypress Semiconductor Corp. It features an organization of 16K words by 4 bits, providing a total memory density of 64 Kbit. The device operates with a maximum access time of 20 ns and utilizes CMOS technology. It is housed in a 28-pin Plastic Small Outline J-Lead (SOJ) package, designated as PDSO28. The component supports asynchronous operation modes and includes automatic power-down capabilities to manage energy consumption during idle states.

Memory IC Feature Summary

• Standard SRAM architecture with 16Kx4 word organization
• CMOS technology for low power consumption
• Automatic power-down functionality
• Asynchronous operation mode

Memory IC Applications

• General-purpose data storage in embedded systems
• Buffer memory for microprocessor interfaces
• Cache memory applications in industrial control units

Memory IC Procurement Notes

Verify the specific suffix 'VC' against official Cypress documentation to confirm package type and temperature range. Ensure compliance with RoHS directives if required, as older Cypress parts may have varying environmental certifications. Confirm pin compatibility with existing PCB footprints, specifically the SOJ-28 outline dimensions. Cross-reference the manufacturer's current lifecycle status to ensure long-term availability for production runs.

Memory IC Selection Notes

Select this component when a 16Kx4 capacity with 20 ns speed is required in a 28-pin SOJ package. Compare against the CY7C162 series for similar specifications but verify pinout differences. Consider the CY7C166-10VC if faster 10 ns access times are needed within the same package family. Evaluate power requirements against the automatic power-down feature for battery-operated designs.

Memory IC Part Context

This part belongs to the Cypress CY7C166 family of standard SRAMs. It shares architectural similarities with other members like the CY7C166-10VC, differing primarily in access speed. The family is designed for general-purpose memory applications requiring reliable data retention and straightforward asynchronous interface protocols without complex control signals.
