Overview
The Renesas Electronics Corporation 7133LA45JI8 is a static random-access memory (SRAM) integrated circuit featuring dual-port, asynchronous architecture. It provides a total storage capacity of 32 kilobits organized as 2K words by 16 bits. The device supports parallel interface communication with a maximum access time of 45 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and is designed for surface mount installation in a 68-lead Plastic Leadless Chip Carrier (PLCC) package measuring 24.21mm x 24.21mm. The component is rated for an ambient operating temperature range of -40°C to +85°C.
Feature Summary
- Dual-port asynchronous architecture enabling independent simultaneous read/write operations on separate ports.
Applications
- High-speed data buffering in telecommunications systems
- Cache memory implementation in embedded processing units
- Data storage in industrial control applications
Procurement Notes
Verify the specific suffix JI8 against official Renesas documentation to confirm package dimensions and lead finish specifications. Confirm RoHS compliance status as historical records indicate potential variations within the 7133SA/LA family. Validate that the 68-PLCC footprint matches the target PCB design requirements before procurement.
Selection Notes
Select this component when a dual-port SRAM solution is required for applications needing concurrent access from two distinct masters. The 45ns speed class offers a balance between performance and power consumption. Ensure the system design accommodates the 68-PLCC surface mount package constraints and the specified 4.5V to 5.5V power supply rails.
Part Context
This part belongs to the Renesas 7133SA/LA series of high-speed dual-port SRAMs. The 'LA' designation typically indicates commercial or extended temperature variants compared to the 'SA' series. These devices are engineered for robust performance in demanding electronic environments requiring reliable, fast, and independent data access capabilities.
Replacement Considerations
The 7133SA45JI8 is a documented substitute within the same manufacturer's portfolio, sharing identical electrical characteristics and pinout compatibility while differing primarily in temperature rating specifications.
