7164L20YG

Overview

The IDT7164L20YG is a high-speed static RAM integrated circuit manufactured by Integrated Device Technology. It provides a storage capacity of 65,536 bits organized as 8K words by 8 bits. The device features an asynchronous parallel interface with a maximum access time of 20 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports low-power standby modes. The component is housed in a 28-pin Small Outline J-Lead (SOJ) package designed for surface-mount applications.

Feature Summary

• High-speed CMOS technology enabling rapid data access
• Low-power standby mode activated by specific control signals
• Battery backup capability for data retention at reduced voltages
• TTL-compatible inputs and outputs for system integration

Applications

• Industrial control systems requiring reliable volatile memory
• Military-grade electronic equipment compliant with MIL-STD-883
• Communication infrastructure utilizing battery-backed storage

Procurement Notes

Verify the exact suffix against official Renesas or IDT documentation, as variations exist between commercial and military grades. Confirm lead times and availability status directly with authorized distributors, as this component may be subject to end-of-life notices or production transfers. Ensure the package type matches the required PCB footprint specifications before ordering.

Selection Notes

Select this component when a 20ns access speed is required for 8Kx8 SRAM configurations. Consider the SOJ package constraints for surface-mount assembly processes. Evaluate the need for extended temperature ranges or military compliance, as these factors influence the specific suffix selection and pricing structure compared to standard commercial variants.

Part Context

This part belongs to the IDT7164 family of 64K-bit static random-access memories. The 'L' designation typically indicates a low-power variant with battery backup support. The 'Y' suffix denotes the 28-SOJ package style. This series is widely used in legacy and specialized embedded systems where fast, non-volatile-like performance with battery retention is necessary.

Replacement Considerations

Check for direct substitutes such as the IDT7164L20YGI or IDT7164S20YGI depending on the required temperature grade. Verify pin compatibility and electrical characteristics against datasheets from Renesas Electronics Corporation, which acquired IDT's semiconductor assets.
