7008S55PF

Memory IC Overview

The Renesas Electronics Corporation 7008S55PF is a high-speed, asynchronous dual-port static random-access memory (SRAM) IC. It provides a storage capacity of 512 kilobits organized as 64K words by 8 bits. The device features a parallel interface with a maximum access time and write cycle time of 55 nanoseconds. It operates on a single 5V power supply within a voltage range of 4.5V to 5.5V. The component is housed in a 100-pin Thin Quad Flat Package (TQFP) measuring 14x14 mm. Designed for surface-mount installation, it supports an industrial operating temperature range from 0°C to 70°C.

Memory IC Feature Summary

• Supports simultaneous independent reads and writes at both ports without conflict
• Includes on-chip hardware semaphore signaling for port arbitration
• Features automatic power-down mode controlled by chip enable signals
• Provides TTL-compatible logic levels for direct microprocessor interfacing

Memory IC Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded processors
• Data acquisition systems requiring concurrent port access
• Master/slave dual-port RAM configurations for 16-bit or wider bus expansion

Memory IC Procurement Notes

Verify the specific suffix 'PF' against the manufacturer's official datasheet to confirm package type and material compliance. Confirm RoHS status, as older variants may not meet current environmental directives. Check for End-of-Life notices or discontinuance notifications prior to final design approval. Ensure compatibility with existing PCB footprints for the 100-TQFP package. Validate that the 55 ns speed grade meets system timing requirements.

Memory IC Selection Notes

Select this component when simultaneous bidirectional data transfer is required between two masters. Compare access times against other 55 ns variants if higher speed is needed. Consider the 100-TQFP package constraints for board space. Evaluate power consumption in active and standby modes relative to system battery life. Verify that the 5V supply voltage aligns with the target system architecture.

Memory IC Part Context

The 7008S55PF belongs to the Renesas 7008S family of dual-port SRAMs. This series is designed for applications needing fast, conflict-free memory sharing. The '55' indicates the 55 nanosecond speed grade. The 'PF' suffix denotes the 100-lead TQFP plastic package. This part serves as a standalone memory block or expands word width in larger systems.

Memory IC Replacement Considerations

Consult the official Renesas product transition documents for qualified substitute part numbers. Verify pin-to-pin compatibility and electrical specifications before substitution. Check for updated packaging or environmental compliance in replacement parts.
