7133SA15JI8

Memory IC Overview

The Renesas Electronics Corporation 7133SA15JI8 is a dual-port, asynchronous static random-access memory (SRAM) integrated circuit. It provides a total storage capacity of 32 kilobits, organized as 2K words by 16 bits. The device features a parallel interface with a maximum access time of 15 nanoseconds and a write cycle time of 15 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a TQFP-100 package. The component is rated for an industrial operating temperature range from 0°C to +70°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports
• Asynchronous operation allowing flexible timing control without external clock synchronization
• CMOS technology ensuring low power consumption during standby and active states

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data storage in industrial automation controllers

Memory IC Procurement Notes

Verify the specific suffix JI8 against official Renesas documentation to confirm the TQFP-100 package and commercial temperature range. Confirm RoHS compliance status as legacy products may vary. Check for End-of-Life notices or production discontinuation announcements prior to procurement planning.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent host and peripheral access. Ensure the system design accommodates the 100-pin TQFP footprint and 4.5V to 5.5V power requirements. Compare against faster variants if sub-15ns latency is critical.

Memory IC Part Context

This part belongs to the Renesas 7133SA series of dual-port SRAMs. It shares architectural similarities with other members like the 7133SA35J but offers significantly higher speed performance. The series is designed for applications requiring high-bandwidth memory sharing between two independent masters.

Memory IC Replacement Considerations

Official substitutes include the IDT7133SA15JI8 due to historical Renesas/IDT lineage. Verify pin compatibility and electrical specifications before substitution.
