7005S55GB

Overview

The Renesas Electronics Corporation 7005S55GB is a static random access memory component with a storage capacity of 64K bits, organized as 8K by 8. It features dual-port architecture and asynchronous parallel interface. The device operates within a voltage range of 4.5V to 5.5V and has an access time of 55 ns. It is housed in a PGA-68 package and supports an operating temperature range from 0°C to +70°C.

Feature Summary

• True dual-ported memory cells allow simultaneous reads of the same memory location
• On-chip port arbitration logic provides hardware support for semaphore signaling between ports
• Automatic power down feature controlled by CE enables low standby power mode

Applications

• Stand-alone 64K-bit Dual-Port RAM systems
• MASTER/SLAVE Dual-Port RAM configurations for 16-bit or more word systems
• Battery backup operation requiring data retention

Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance. Confirm package integrity for PGA-68 housing. Check for discontinuance notifications prior to procurement. Ensure supply chain sources are authorized distributors. Validate electrical specifications against current design requirements.

Selection Notes

Select this component for applications requiring independent port access to shared memory locations. Consider the PGA-68 through-hole package for specific board layout needs. Verify that the 55 ns access time meets system timing constraints. Ensure the 5V single supply voltage aligns with the target platform's power distribution network.
