7005L25PF

Overview

The Renesas Electronics Corporation 7005L25PF is a high-speed, asynchronous dual-port static random-access memory (SRAM) with a storage capacity of 64 kbit. The memory organization is configured as 8K x 8 bits. It features parallel interface access with a maximum access time of 25 ns. The device operates on a single 5V power supply within a voltage range of 4.5 V to 5.5 V. It supports surface-mount installation in a 64-pin TQFP package and functions within an industrial temperature range from -40°C to +85°C.

Feature Summary

• True dual-ported memory cells enable simultaneous independent reads of the same memory location from 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 inputs and outputs ensure compatibility with standard logic families using a single 5V supply.

Applications

• Stand-alone 64K-bit dual-port RAM systems
• Master/Slave dual-port RAM configurations for 16-bit or wider word systems
• Industrial control applications requiring wide operating temperature ranges
• Battery-backed data retention systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and moisture sensitivity level handling requirements prior to assembly. Check for specific ordering suffixes that may indicate package variations or environmental certifications. Ensure supply chain stability given the component's industrial classification.

Selection Notes

Select this component when simultaneous independent access to shared memory is required without external arbitration logic. Consider the 25 ns access speed and 64-TQFP package dimensions for board layout constraints. Evaluate the -40°C to +85°C temperature range against environmental conditions. Compare power consumption characteristics in active and standby modes relative to system battery backup requirements.

Part Context

The 7005L25PF belongs to the Renesas 7005 series of high-speed dual-port SRAMs. This family provides flexible memory solutions for embedded systems needing concurrent processor access. The 'L' designation typically indicates the industrial temperature grade variant within the product line. The series supports various package options including TQFP and PGA to accommodate different design footprints.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout and electrical specifications carefully if considering alternative dual-port SRAM devices from other manufacturers.
