7005S55PF

Overview

The Renesas Electronics Corporation 7005S55PF is a high-speed, asynchronous dual-port static random-access memory (SRAM) device. It provides a storage capacity of 64 kilobits organized as 8K words by 8 bits. The component features parallel interface access with a maximum access time of 55 nanoseconds. It operates on a single 5V power supply within a voltage range of 4.5V to 5.5V. The device is housed in a 64-pin Thin Quad Flat Package (TQFP) with dimensions of 14x14 mm and supports surface-mount installation. It functions within an industrial temperature range of 0°C to 70°C.

Feature Summary

• True dual-ported memory architecture enabling simultaneous independent reads from the same memory location by both ports.
• Integrated hardware support for semaphore signaling and port arbitration logic to manage data access conflicts.
• Automatic power-down feature controlled by chip enable signals to minimize standby power consumption.
• TTL-compatible inputs and outputs designed for direct interfacing with standard digital logic systems.

Applications

• Stand-alone 64K-bit dual-port RAM modules
• Master/Slave dual-port configurations for 16-bit or wider word systems
• Battery-backed memory systems requiring low standby current

Procurement Notes

Verify component authenticity through authorized channels due to potential availability issues. Confirm package integrity and moisture sensitivity handling procedures prior to assembly. Ensure design compatibility with 5V logic levels and TQFP footprint requirements. Review datasheet specifications for electrical characteristics and thermal limits before integration.

Selection Notes

Select this component for applications requiring concurrent access to shared memory resources without external arbitration overhead. Consider the 55ns access speed and 64-pin TQFP form factor for space-constrained designs. Evaluate power management needs against the automatic power-down capabilities. Verify that the operating temperature range meets the specific environmental conditions of the target application.
