Overview
The Renesas Electronics Corporation 7164L45TPG is an asynchronous static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 64 kilobits, organized as 8K words by 8 bits. The device features a parallel interface with a maximum access time of 45 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and supports through-hole installation in a 28-pin dual inline package (PDIP). The component is designed for commercial temperature applications ranging from 0°C to 70°C.
Feature Summary
- Asynchronous parallel SRAM architecture for general-purpose data storage
- Volatile memory technology retaining data only during power application
- Through-hole mounting capability via standard 28-pin DIP configuration
Applications
- Industrial control systems requiring non-volatile-like temporary buffering
- Embedded hardware prototypes utilizing legacy DIP footprints
- Consumer electronics employing 5V logic families
Procurement Notes
Verify component authenticity due to end-of-life status. Confirm package integrity upon receipt. Check datasheet for specific electrical tolerances. Ensure compatibility with existing 5V logic levels. Validate supplier credentials for obsolete semiconductor parts.
Selection Notes
Select this part for designs requiring 64Kbit capacity in a DIP format. Suitable for 5V systems needing 45ns access speeds. Consider pinout compatibility with existing PCB layouts. Evaluate thermal requirements for commercial grade operation. Assess availability constraints for discontinued inventory.
Part Context
This component belongs to the 7164 series of asynchronous SRAMs manufactured by Renesas Electronics. It shares architectural similarities with other devices in the family but differs in speed grade and packaging. The 7164L45TPG specifically denotes the 45 nanosecond access variant in a plastic dual inline package.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pin-to-pin compatibility with alternative 64Kbit 28-DIP SRAMs if sourcing new production units.
