7007S20J

Memory IC Overview

The Renesas Electronics Corporation 7007S20J is a high-speed, asynchronous dual-port static random-access memory (SRAM) device. It features a storage capacity of 128 kbit organized as 16k words by 8 bits. The component supports parallel interface operations with a maximum access time of 20 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and has a maximum power supply current of 290 mA. The device is designed for surface-mount installation in a PLCC-68 package and functions reliably within an ambient temperature range of 0°C to +70°C.

Memory IC Feature Summary

• Provides independent read/write access to two masters simultaneously via dual-port architecture
• Supports asynchronous parallel data transfer with fast access speeds
• Maintains volatile data storage without requiring continuous refresh cycles

Memory IC Applications

• High-performance embedded systems requiring concurrent data access
• Industrial control units needing reliable temporary data buffering
• Communication equipment utilizing shared memory architectures

Memory IC Procurement Notes

Verify the specific suffix designation against official Renesas documentation to confirm pinout compatibility and electrical characteristics. Confirm that the required operating temperature range aligns with the commercial grade specifications. Ensure that the target application circuit matches the 4.5V to 5.5V supply voltage requirements. Check for any end-of-life notices or alternative package recommendations from the manufacturer before finalizing procurement plans.

Memory IC Selection Notes

Select this component when simultaneous independent access to 128 kbit of memory is required. Choose this part over single-port alternatives if system latency must be minimized through concurrent master operations. Verify that the PLCC-68 footprint fits the printed circuit board layout constraints. Ensure the design accommodates the specified 290 mA maximum current consumption during active operation.

Memory IC Part Context

This device belongs to the 7007 series of dual-port SRAMs manufactured by Renesas Electronics. The series offers various speed grades and organization options to suit different performance requirements. The 7007S20J specifically targets applications needing moderate speed and standard 8-bit word width. It serves as a legacy component for maintaining existing designs that rely on established dual-port memory interfaces.

Memory IC Replacement Considerations

Consult official Renesas cross-reference guides for verified substitutes. Consider parts like the 7006L20JG for similar functionality in industrial temperature ranges. Evaluate the 7007L20JGI8 for extended temperature capabilities if required. Always validate pin compatibility and electrical parameters before substituting.
