Overview
The Renesas Electronics Corporation 7164S25YGI is a 64 Kbit (8K x 8) static random-access memory (SRAM) device manufactured using BICMOS technology. It features asynchronous parallel interface operation with a maximum access time of 25 ns. The component operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a 28-pin SOJ package. It is rated for industrial temperature environments ranging from -40°C to +85°C.
Feature Summary
- Asynchronous parallel data transfer architecture
- BICMOS semiconductor manufacturing process
- Industrial-grade thermal stability rating
Applications
- Embedded system data storage
- Industrial control unit memory buffers
- High-speed logic circuitry temporary storage
Procurement Notes
Verify current availability status as the component may be discontinued or subject to limited supply constraints. Confirm RoHS compliance details and moisture sensitivity level requirements before integration into production workflows. Ensure compatibility with existing PCB footprints and soldering profiles for the 28-SOJ package variant.
Selection Notes
Select this component when a 64 Kbit capacity with 25 ns speed is required for industrial applications. Consider the 28-SOJ form factor for surface-mount assembly needs. Evaluate power consumption limits against the specified maximum current draw and verify that the 5V logic levels match the host system design.
Part Context
This part belongs to the 7164S series of high-speed SRAMs produced by Renesas Electronics. It serves as a non-volatile-like storage solution for volatile memory applications requiring fast read/write cycles without refresh overhead. The suffix YGI denotes specific packaging and temperature grade characteristics within the product family.
Replacement Considerations
Check for direct pin-compatible alternatives within the same manufacturer's portfolio if supply is restricted. Verify electrical parameter equivalence for access time, voltage ranges, and package dimensions before substituting.
