7005L35JI8

Overview

The Renesas Electronics Corporation 7005L35JI8 is a dual-port, asynchronous 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 a parallel interface with a maximum access time of 35 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and supports surface-mount installation in an 84-pin PLCC package measuring 24.21mm by 24.21mm.

Feature Summary

• Supports simultaneous independent read and write operations through two distinct ports for high-throughput data handling.
• Utilizes asynchronous logic architecture that does not require a global clock signal for operation.
• Employs standard parallel data bus interfaces for straightforward integration into existing digital systems.

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data acquisition systems requiring rapid temporary storage

Procurement Notes

Verify component authenticity through authorized distributors due to potential availability from legacy inventory. Confirm RoHS compliance status as older manufacturing runs may differ from current standards. Validate package integrity upon receipt to ensure pin alignment matches the 84-PLCC specification before soldering.

Selection Notes

Select this component when dual-port functionality is required for concurrent master-slave memory access. Ensure the system design accommodates the 4.5V to 5.5V power supply requirements. Consider the 35ns access speed against application latency needs and verify that the 84-PLCC footprint fits the printed circuit board layout constraints.
