7007L35J

Memory IC Overview

The Renesas Electronics Corporation 7007L35J is a static random access memory (SRAM) device with a total storage capacity of 256 kbit. The memory organization is structured as 32k x 8 bits. It features an asynchronous dual-port architecture with a parallel interface, allowing independent read and write operations on two ports simultaneously. The maximum access time for this component is specified at 35 ns. It operates within a supply voltage range of 4.5 V to 5.5 V. The device is housed in a 68-PLCC package, specifically a 68-LCC (J-leaded) surface-mount configuration measuring 24.21x24.21 mm. The operational temperature range extends from 0°C to 70°C.

Memory IC Feature Summary

• Supports simultaneous independent read and write operations through its dual-port architecture
• Utilizes a parallel interface for data transfer between the memory core and external systems
• Provides high-speed asynchronous data access capabilities

Memory IC Applications

• Data buffering in high-performance computing systems
• Cache memory implementation in embedded controllers
• FIFO buffer applications requiring concurrent port access

Memory IC Procurement Notes

This component is officially listed as discontinued by the manufacturer. Availability is restricted, and sourcing may require engaging with authorized distributors or secondary market suppliers. Verify the specific revision level and RoHS compliance status, as the product documentation indicates it does not meet current RoHS standards. Ensure that the 68-PLCC package footprint matches the target PCB design before procurement.

Memory IC Selection Notes

Select this part when a system requires true dual-port SRAM functionality with a 32k x 8 organization. The 35 ns access speed suits moderate-to-high frequency applications. Consider the 5V operating voltage requirement and the 68-PLCC package constraints during board layout. Compare against newer variants like the 7007L15JG if faster access times are needed, noting differences in package and availability.

Memory IC Part Context

The 7007L35J belongs to the Renesas 7007L series of dual-port SRAMs. This family is designed for applications needing independent access to shared memory resources. The '35' suffix denotes the 35 ns access time variant. It shares architectural similarities with other members like the 7007L25G but differs in speed specifications. The device represents a legacy solution for parallel memory interfacing.

Memory IC Replacement Considerations

Public confirmed substitute part numbers include IDT7007L35J. Other family members such as 7007L15JG offer faster speeds but may differ in package or availability status.
