7005S15PF

Overview

The Renesas Electronics Corporation 7005S15PF is a high-speed 64-kbit (8K x 8) dual-port static random-access memory. It operates asynchronously with a maximum access time of 15 ns and supports parallel interfaces. The device functions on a single 5V power supply, ranging from 4.5 V to 5.5 V, with a maximum supply current of 310 mA. It is housed in a 68-pin PLCC package and supports surface-mount installation. The component operates within a commercial temperature range of 0°C to +70°C.

Feature Summary

• True dual-ported memory cells enabling simultaneous independent reads of the same memory location by both ports.
• Integrated hardware support for semaphore signaling and port arbitration logic to manage data conflicts between master and slave operations.
• Automatic power-down feature controlled by chip enable signals to reduce standby power consumption.

Applications

• Stand-alone 64K-bit dual-port RAM systems
• Master/Slave dual-port configurations for 16-bit or wider word systems
• Battery backup applications requiring 2V data retention

Procurement Notes

Verify the specific suffix against official documentation, as variations exist between PF and PFG packaging types. Confirm RoHS compliance status, as some variants in this series are non-compliant. Check moisture sensitivity levels and lead-free availability before integration into production workflows.

Selection Notes

Select this component when simultaneous independent access to shared memory locations is required without external arbitration logic. Ensure the system design accommodates the 68-pin PLCC footprint and 5V TTL-compatible I/O requirements. Verify that the 15 ns access speed meets the timing constraints of the target application bus.

Part Context

This part belongs to the Renesas 7005 series of high-speed dual-port SRAMs. The series provides flexible memory solutions for embedded systems requiring concurrent data access. Variants differ primarily in access speed and package type, such as TQFP or PLCC configurations.

Replacement Considerations

IDT7005S15J8 is listed as an alias for this component. Other series members like IDT7005S25PFI offer slower speeds but similar functionality. Verify pin compatibility and electrical specifications when substituting with other dual-port SRAM devices.
