Overview
The Renesas Electronics Corporation 7164L20YG8 is a 64Kbit (8K x 8) asynchronous static random-access memory (SRAM) integrated circuit. It features a parallel interface with a maximum access time of 20 nanoseconds and a write cycle time of 20 nanoseconds. The device operates on a single 5V power supply, ranging from 4.5V to 5.5V. It is housed in a 28-pin Small Outline J-Lead (SOJ) surface-mount package. The component supports an industrial operating temperature range from -40°C to +85°C.
Feature Summary
- Asynchronous SRAM technology providing fast data access for system memory applications
- Parallel interface architecture supporting standard bus protocols
- Industrial-grade temperature rating for reliable operation in harsh environments
Applications
- Embedded systems requiring volatile data storage
- Industrial control equipment memory buffers
- Automotive electronic subsystems within specified temperature ranges
Procurement Notes
Verify the current lifecycle status as the component may be discontinued or subject to limited availability. Confirm that the 28-SOJ package dimensions match the target PCB footprint. Ensure voltage levels align with the 4.5V to 5.5V specification before integration into the design.
Selection Notes
Select this part when a 64Kbit capacity with 20ns speed is required in a surface-mount SOJ package. Consider the industrial temperature range if the application environment exceeds commercial limits. Verify compatibility with existing parallel bus architectures and ensure adequate power supply stability within the specified voltage window.
Part Context
This component belongs to the 7164 series of asynchronous SRAMs manufactured by Renesas Electronics. The series offers various speed grades and packaging options to support different memory requirements in embedded and industrial applications. The L suffix typically denotes the industrial temperature range variant.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Users should consult official Renesas channels for qualified alternatives or obsolescence management strategies.
