7007S55J8

Memory IC Overview

The 7007S55J8 is a dual-port static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It provides a storage capacity of 256 kilobits, organized as 32K words by 8 bits. The device features an asynchronous parallel interface with a maximum access time and write cycle time of 55 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 68-lead Plastic Leadless Chip Carrier (PLCC) package measuring 24.21mm by 24.21mm.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access from two distinct processors or systems
• Asynchronous operation allowing flexible timing control without requiring a system clock signal
• Parallel data interface supporting standard digital logic connections for high-speed data transfer

Memory IC Applications

• High-performance embedded systems requiring shared memory resources
• Industrial automation controllers needing fast data buffering
• Telecommunications equipment utilizing asynchronous communication protocols

Memory IC Procurement Notes

This component has been officially discontinued by the manufacturer. Verification of availability is restricted to existing stock held by authorized distributors or third-party suppliers. Buyers must confirm the authenticity and physical condition of units prior to acquisition, as new production is no longer supported. Compliance with environmental regulations should be verified against specific lot markings due to the product's age.

Memory IC Selection Notes

Engineers replacing this part should evaluate current dual-port SRAM offerings that match the 32K x 8 organization and 55ns speed grade. Compatibility checks must ensure equivalent voltage levels and pin configurations to maintain board integrity. Alternative packages may require adapter solutions if the original PLCC footprint cannot be reused in modern designs.

Memory IC Part Context

The 7007S55J8 belongs to the broader 7007 series of dual-port SRAMs produced by Renesas Electronics. This family is designed for applications demanding concurrent read/write operations from separate ports. The specific J8 suffix denotes the plastic leadless chip carrier packaging variant, distinguishing it from other form factors within the same electrical specification group.

Memory IC Replacement Considerations

Direct substitutes include IDT7007S55J8 and IDT7007S55JI8, which share identical electrical characteristics and pinouts.
