7006L20PFI8

Overview

The Renesas Electronics Corporation 7006L20PFI8 is a dual-port asynchronous static random-access memory (SRAM) device. It provides a total storage capacity of 128 kbit, organized as 16K words by 8 bits. The component features a parallel interface with a maximum access time of 20 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a 64-pin TQFP package. The device is rated for an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous access to the same memory array
• Asynchronous operation without requiring a system clock signal
• Parallel data interface for direct connection to microprocessors

Applications

• Buffering data between high-speed processors and slower peripherals
• Cache memory implementation in embedded systems
• Data logging applications requiring rapid write cycles

Procurement Notes

Verify the specific suffix PFI8 to confirm the 64-TQFP package and lead-free status. Confirm RoHS compliance requirements against current environmental regulations. Check for end-of-life notices or obsolescence warnings from Renesas. Ensure the supplier provides valid traceability documentation for industrial-grade components.

Selection Notes

Select this part when dual-port functionality is required for 8-bit wide data paths. Compare against single-port alternatives if only one master accesses the memory. Verify that the 20 ns access speed meets the system timing constraints. Ensure the 5V logic levels are compatible with the target processor I/O voltages.

Part Context

This component belongs to the 7006L series of dual-port SRAMs from Renesas. It shares architectural similarities with other members like the 7006L15 but differs in access speed and package options. The series is designed for applications needing shared memory resources without complex arbitration logic.

FAQ

Can both ports be accessed simultaneously?

Yes, the dual-port architecture allows Port A and Port B to operate independently at the same time.

What is the memory organization?

The memory is organized as 16K x 8, providing 128 Kbits of total storage.
