7133LA25JGI8

Memory IC Overview

The Renesas Electronics Corporation 7133LA25JGI8 is a dual-port asynchronous static random-access memory (SRAM) integrated circuit. It provides a total storage capacity of 32 kbit, organized as 2K words by 16 bits. The device features a parallel interface with a maximum access time of 25 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum power supply current of 300 mA. The component is designed for surface-mount installation in a 68-pin PLCC package measuring 24.21 x 24.21 mm. It functions reliably across an operating temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Supports independent simultaneous read/write operations at both Port A and Port B without bus contention
• Utilizes CMOS technology for low power consumption during active and standby modes
• Features asynchronous operation with dedicated chip selects and output enables for each port

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in industrial control systems
• Data storage in network switching hardware

Memory IC Procurement Notes

Verify the specific suffix JGI8 to confirm the 68-PLCC package and commercial temperature grade. Confirm RoHS compliance status as manufacturing updates may affect regulatory classification. Check for obsolescence notices or lifecycle changes directly from Renesas documentation before finalizing procurement plans.

Memory IC Selection Notes

Select this component when a 32Kbit dual-port architecture with 25 ns speed is required. Ensure the design accommodates the 4.5V to 5.5V supply voltage constraints. Verify that the 68-PLCC footprint fits the PCB layout and that thermal management supports the specified operating temperature range.

Memory IC Part Context

This part belongs to the 7133LA series of dual-port SRAMs from Renesas. It serves as a successor or alternative to older IDT-branded parts like the IDT7133SA25J. The LA series typically denotes enhanced performance or updated manufacturing processes compared to the legacy SA series while maintaining pin compatibility.

Memory IC Replacement Considerations

The 7133SA25J is listed as a discontinued predecessor. The 7133LA25PFGI8 is a different package variant (TQFP-100) and requires board redesign. No direct pin-compatible active substitutes are confirmed in the provided data.
