7133LA35PF8

Overview

The Renesas 7133LA35PF8 is a dual-port asynchronous static random-access memory (SRAM) integrated circuit. It provides a total storage capacity of 32Kbits, organized as 2K words by 16 bits. The device features a maximum access time of 35 nanoseconds and operates within a supply voltage range of 4.5V to 5.5V. It is housed in a 100-pin Thin Quad Flat Package (TQFP) with dimensions of 14x14 mm. The component supports surface-mount installation and is rated for an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous access to the same memory array via two separate port interfaces.
• Asynchronous operation allowing flexible timing control without reliance on a global clock signal.
• CMOS technology implementation ensuring low power consumption during active and standby states.

Applications

• Embedded systems requiring high-speed data buffering between processors and peripherals.
• Industrial automation controllers needing reliable temporary storage for real-time processing tasks.
• Telecommunications equipment utilizing parallel memory interfaces for signal processing applications.

Procurement Notes

Verify the specific suffix designation against official Renesas documentation to confirm package type and temperature grade. Confirm RoHS compliance status as manufacturing processes may vary. Check for End-of-Life notices or Product Change Notifications that may affect long-term availability. Ensure moisture sensitivity level handling procedures are followed during assembly.

Selection Notes

Select this component when a 32Kbit dual-port configuration is required with 35ns performance. Ensure the design supports 5V logic levels and TQFP-100 footprint constraints. Compare against single-port alternatives if only one interface is needed. Verify thermal management capabilities for the specified industrial temperature range.

Part Context

This part belongs to the Renesas 7133LA series of dual-port SRAMs. It shares architectural similarities with other members like the 7133SA35PFG8 but differs in operating temperature specifications. The LA series is generally designed for broader industrial environments compared to commercial variants.

Replacement Considerations

Officially documented substitutes include the 7133LA20PFG8, which offers faster 20ns access times within the same package and voltage range.
