Overview
The Renesas Electronics Corporation 7133LA35JI8 is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 32 kilobits, organized as 2K words by 16 bits. The device features asynchronous parallel interface operation with a maximum access time of 35 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports an industrial temperature range from -40°C to +85°C. The component is housed in a 68-pin Plastic Leadless Chip Carrier (PLCC) package.
Feature Summary
- Supports simultaneous independent access to the same memory location from both ports via true dual-ported memory cells.
- Includes on-chip port arbitration logic to manage concurrent read/write operations without external control.
- Provides interrupt flags to facilitate communication and status signaling between the two ports.
Applications
- High-speed data buffering in telecommunications equipment
- Network switch and router packet storage
- Industrial automation control systems
Procurement Notes
Verify current production status as this part number may be discontinued or subject to end-of-life notices. Confirm RoHS compliance requirements against specific suffix variations. Check for valid replacement components if primary sourcing is unavailable. Ensure moisture sensitivity level handling protocols are followed during assembly.
Selection Notes
Select this component when dual-port functionality is required for high-throughput applications. Compare access times and power consumption against alternative SRAM families. Verify package compatibility with existing PCB footprints. Consider temperature ratings for harsh environmental deployments.
Part Context
This device belongs to the Renesas 7133SA/LA series of dual-port SRAMs. It shares architectural similarities with other members like the 7133SA35JI8 but differs in speed grade and commercial/industrial temperature specifications. The LA suffix typically denotes industrial temperature range support.
Replacement Considerations
Publicly confirmed substitute part numbers for this specific model were not identified in the provided documentation. Consult manufacturer obsolescence notices for recommended alternatives.
