7006S15PF

Overview

The Renesas Electronics Corporation 7006S15PF is a high-speed, asynchronous dual-port static random access memory (SRAM) with a storage capacity of 128 kbit. The device features a memory organization of 16K x 8 and supports parallel interface communication. It operates within a supply voltage range of 4.5 V to 5.5 V and offers an access time of 15 ns. Designed for surface-mount applications, the component is housed in a 64-pin TQFP package. It functions as a stand-alone dual-port RAM or in master/slave configurations for wider data bus systems.

Feature Summary

• True dual-ported memory cells enable simultaneous independent reads from the same memory location by both ports.
• On-chip hardware support for semaphore signaling facilitates port arbitration and synchronization between processors.
• Automatic power-down feature controlled by chip enable allows entry into low standby power mode.
• TTL-compatible single 5V power supply operation ensures compatibility with standard logic families.

Applications

• Stand-alone 128K-bit dual-port memory modules
• Master/Slave dual-port RAM combinations for 16-bit or wider word systems
• Battery-backed data retention systems requiring 2V data retention capability

Procurement Notes

Verify current availability status as this component may be discontinued or subject to limited production runs. Confirm RoHS compliance requirements against specific project needs, noting that older variants may not meet current environmental standards. Ensure proper handling procedures are followed due to moisture sensitivity classification. Validate pinout compatibility with existing PCB layouts before procurement.

Selection Notes

Select this component when simultaneous dual-port access is required for high-speed data sharing between two processors. The 15 ns access time suits applications demanding rapid data retrieval. Consider the 64-pin TQFP package for surface-mount assembly constraints. Evaluate power consumption profiles against system thermal limits, as maximum supply current can reach 310 mA during active operation.

Part Context

The 7006 series represents a family of high-speed dual-port SRAMs designed for complex embedded systems. This specific model utilizes asynchronous operation, allowing flexible timing control for each port independently. The architecture supports interrupt flags and busy signals to manage contention effectively. It serves as a bridge between different processing speeds in mixed-signal environments.

Replacement Considerations

Direct substitutes include IDT7006S15PF. Verify functional equivalence regarding pinouts and electrical characteristics before substitution.
