7005S55J

Overview

The Renesas 7005S55J is a dual-port static random-access memory (SRAM) device with a storage capacity of 64 kbit, organized as 8k x 8. It operates on a single 5V power supply within a voltage range of 4.5V to 5.5V. The component features an asynchronous parallel interface with a maximum access time of 55 ns. It is housed in a 68-pin PGA package and supports surface-mount installation. The device functions within an industrial temperature range of 0°C to +70°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations for both ports
• Asynchronous parallel interface supporting standard TTL logic levels
• Integrated control signals including busy, interrupt, master, semaphore, and slave modes

Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded processors
• Data logging applications requiring independent port access

Procurement Notes

Verify the specific suffix J against official Renesas documentation to confirm package type and pinout compatibility. Confirm RoHS compliance status as historical data may vary. Check for active discontinuance notices or lifecycle changes before finalizing procurement plans.

Selection Notes

Select this component when independent dual-port access is required for 64 kbit SRAM. Ensure the design accommodates the 68-pin PGA footprint and 55 ns timing constraints. Verify that the system voltage remains within the 4.5V to 5.5V operating range.

Part Context

This part belongs to the Renesas 7005 series of dual-port SRAMs. It shares architectural similarities with other variants in the family but differs in access speed and packaging. The 7005 series is designed for applications requiring high-bandwidth data sharing between two independent masters.
