Overview
The Renesas 7164L20TPGI is a 64Kb (8K x 8) asynchronous static random-access memory (SRAM) integrated circuit. It features a parallel interface with a maximum access time and write cycle time of 20 nanoseconds. The device operates on a single 4.5V to 5.5V power supply and supports an industrial temperature range from -40°C to +85°C. It is housed in a 28-pin plastic dual in-line package (PDIP) designed for through-hole mounting.
Feature Summary
- Asynchronous SRAM technology requiring no clock or refresh cycles
- Parallel data interface for direct system connection
- Industrial-grade wide operating temperature capability
Applications
- Data storage in industrial control systems
- Buffer memory in embedded processing applications
- Non-volatile backup storage interfaces
Procurement Notes
Verify the exact suffix configuration against official Renesas documentation, as variations exist between PDIP and SOJ packages. Confirm that the specific part number matches the required lead frame and moisture sensitivity level for your assembly process. Cross-reference with IDT legacy naming conventions if integrating into existing designs.
Selection Notes
Select this component when a 64Kb capacity with 20ns speed is required for through-hole PCB layouts. Ensure the design accommodates the 28-pin DIP footprint and 5V logic levels. Consider alternative surface-mount variants like the YGI suffix if board space constraints preclude the use of dual in-line packaging.
Part Context
This part belongs to the 7164L family of high-speed CMOS static RAMs originally developed by Integrated Device Technology (IDT) and now manufactured by Renesas Electronics. The family provides reliable volatile memory solutions for various computing and industrial environments, maintaining compatibility with standard TTL and LVTTL logic families.
Replacement Considerations
Official substitutes include the 7164L20YGI (surface mount SOJ variant) and the 7164L20TPG (commercial temperature grade). Verify pinout compatibility and electrical specifications before substitution.
