7005L17PF

Overview

The Renesas Electronics Corporation 7005L17PF is a high-speed, asynchronous dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 64 kilobits organized as 8K words by 8 bits. The device features parallel interface access with a maximum access time of 17 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 64-pin Thin Quad Flat Package (TQFP) measuring 14x14 mm and supports surface-mount installation. It functions within an ambient temperature range of 0°C to 70°C.

Feature Summary

• True dual-ported memory architecture enabling simultaneous independent reads from both ports without conflict.
• On-chip hardware support for semaphore signaling and automatic port arbitration logic to manage data integrity.
• Integrated interrupt flag functionality to signal status conditions between the two memory ports.
• 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 parallel data exchange.
• Master/Slave dual-port configurations for expanding data bus widths to 16 bits or more.
• Industrial control applications utilizing asynchronous communication between processing units.
• Battery-backed systems requiring 2V data retention capabilities during main power loss.

Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm package markings match the 64-TQFP specification. Check for moisture sensitivity level 3 compliance if reflow soldering is required. Ensure the supplier provides traceability documentation consistent with Renesas quality standards. Validate that the specific lot meets the 0°C to 70°C operating temperature range requirements.

Selection Notes

Select this component when true dual-port independence is required for concurrent read operations. Choose based on the 17 ns access speed for asynchronous parallel interfaces. Consider the 64-TQFP package for surface-mount assembly constraints. Evaluate the single 5V supply requirement against system power architectures. Verify compatibility with existing semaphore and interrupt logic implementations.

Part Context

The 7005L17PF belongs to the Renesas 7005 series of high-speed dual-port SRAMs. This family is designed for applications needing simultaneous access from two distinct masters. The 'L' suffix typically denotes the commercial temperature grade variant. The part integrates advanced arbitration logic to prevent bus contention during overlapping access cycles.

Replacement Considerations

Public confirmed substitute: 7005L15PFG. Verify pinout compatibility and electrical parameter alignment before integration.
