7006L35PF

Overview

The Renesas Electronics Corporation 7006L35PF is a high-speed, asynchronous dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 128 kilobits organized as 16K words by 8 bits. The device features parallel interface access with a maximum access time of 35 nanoseconds. It operates on a single 4.5V to 5.5V power supply and supports surface-mount installation in a 64-pin Thin Quad Flatpack package measuring 14x14 millimeters. The component is designed for industrial temperature ranges.

Feature Summary

• True dual-ported memory architecture enabling simultaneous independent reads from both ports without conflict.
• On-chip hardware support for semaphore signaling and port arbitration logic to manage data integrity between processors.
• Automatic power-down functionality controlled by chip enable signals to minimize standby power consumption.
• TTL-compatible inputs and outputs allowing direct interfacing with standard digital logic systems.

Applications

• Stand-alone 128K-bit dual-port RAM modules in embedded systems
• Master/Slave dual-port configurations for 16-bit or wider word data buses
• High-speed data buffering between asynchronous processing units
• Industrial control systems requiring reliable concurrent memory access

Procurement Notes

Verify the specific suffix designation against official Renesas documentation to confirm exact package dimensions and temperature grade. Confirm RoHS compliance status as older variants may differ. Check for active production status or obsolescence notices before finalizing procurement plans. Ensure ESD handling protocols are followed during assembly due to moisture sensitivity classification.

Selection Notes

Select this component when a system requires true dual-port capability with independent address and data buses for two distinct masters. Compare access times against system clock requirements to ensure the 35ns speed meets timing constraints. Evaluate power consumption profiles if battery backup operation is required, noting the low standby mode capabilities. Verify that the 64-pin TQFP package fits within the available PCB real estate constraints.

Part Context

The 7006 series represents a family of high-speed dual-port SRAMs designed for applications needing concurrent access. This specific model utilizes advanced CMOS technology to deliver performance while maintaining compatibility with standard 5V logic levels. It serves as a critical interconnect solution in complex digital architectures where data sharing between multiple processors must occur without software overhead or bus contention.

Replacement Considerations

Official upgrade alternatives include the 7005L15PFG. Verify pinout compatibility and electrical specifications before substitution. Cross-reference datasheets to ensure functional equivalence in semaphore and interrupt handling mechanisms.
