7005S35PFG

Overview

The Renesas Electronics Corporation 7005S35PFG is a high-speed, asynchronous dual-port static random-access memory (SRAM) device. It features a storage capacity of 64 kbit organized as 8k x 8 bits. The component supports parallel interface communication with an access time of 35 ns. It operates on a single 5V power supply within a voltage range of 4.5 V to 5.5 V. The maximum supply current is specified at 250 mA. The device is housed in a 64-pin Thin Quad Flat Package (TQFP) designed for surface-mount technology. It functions within a commercial temperature range from 0°C to +70°C.

Feature Summary

• True dual-ported memory architecture enabling simultaneous independent reads and writes from two separate ports without conflict.
• On-chip hardware support for semaphore signaling and port arbitration logic to manage data integrity between master and slave configurations.
• Integrated interrupt flag functionality to signal status changes or completion events to connected processors.
• Automatic power-down feature controlled by chip enable inputs to minimize standby power consumption.

Applications

• Stand-alone 64K-bit dual-port RAM systems requiring high-speed data buffering.
• Master/slave dual-port RAM combinations for expanding data bus widths to 16 bits or more in complex architectures.
• Industrial control systems utilizing asynchronous parallel interfaces for real-time data exchange.
• Battery-backed memory applications leveraging the device's low standby power modes.

Procurement Notes

Verify the specific suffix against official documentation, as package variations exist within the 7005 series. Confirm RoHS compliance status and moisture sensitivity levels prior to integration. Check for end-of-life notices or long-term supply agreements if available. Ensure the selected variant matches the required thermal and electrical specifications for the target environment.

Selection Notes

Select this component when true dual-port independence is required for concurrent data access. Consider the 35 ns access speed and 64-pin TQFP form factor for surface-mount designs. Evaluate the need for on-chip arbitration features over external logic solutions. Verify compatibility with 5V TTL-compatible I/O levels and standard parallel interface protocols.

Part Context

The 7005 series represents a family of high-speed dual-port SRAMs designed for versatile memory applications. Variants differ primarily in access speeds, package types, and operating temperature ranges. This specific model belongs to the commercial grade subset, offering a balance of performance and cost for general-purpose industrial and infrastructure electronics.

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source material. Cross-reference pinouts and electrical characteristics carefully when evaluating alternative components from other manufacturers or different Renesas variants.
