7005L12PF8

Overview

The Renesas Electronics Corporation 7005L12PF8 is a high-speed, asynchronous dual-port static random-access memory (SRAM) IC. It features a storage capacity of 64 kbit organized as 8K x 9 bits. The device supports parallel interface operation with a maximum access time of 12 ns. It operates on a single 5V power supply within a voltage range of 4.5V to 5.5V. The component is housed in an 80-TQFP package measuring 14x14 mm and is designed for industrial temperature ranges from 0°C to +70°C.

Feature Summary

• True dual-ported memory architecture enabling simultaneous independent read/write operations by two masters.
• On-chip hardware support for semaphore signaling and port arbitration logic to manage bus conflicts.
• Integrated interrupt flag functionality to signal status changes between ports.
• Asynchronous operation allowing flexible timing control from either port without clock synchronization.

Applications

• Stand-alone 64K-bit dual-port RAM systems
• Master/Slave dual-port configurations for 16-bit or wider data bus architectures
• Industrial control systems requiring non-blocking memory access

Procurement Notes

Verify the specific suffix 'L' against official Renesas documentation to confirm lead-free compliance and RoHS status, as legacy variants may differ. Confirm the 80-pin TQFP package availability and moisture sensitivity level requirements during storage and handling. Ensure the 12 ns access speed meets system timing constraints before finalizing procurement orders.

Selection Notes

Select this component when simultaneous bidirectional data transfer is required without external arbitration circuitry. The 8K x 9 organization suits applications needing parity bit support or extended word widths. Verify that the 5V TTL-compatible I/O levels match the host processor's voltage domain. Consider the 80-TQFP package dimensions for PCB layout compatibility.

Part Context

The 7005 series represents a family of high-speed dual-port SRAMs designed for complex embedded systems. This specific model belongs to the asynchronous variant line, offering flexibility in clock domains. It serves as a bridge between different processing speeds, facilitating efficient data exchange in multi-master environments common in telecommunications and industrial automation.

Replacement Considerations

Direct substitutes include other 8K x 8 or 8K x 9 dual-port SRAMs with similar access times and pinouts. Verify functional equivalence regarding semaphore and interrupt logic if replacing with generic dual-port memories. Check for package dimension compatibility to ensure mechanical fit without redesigning the footprint.
