7133LA70J8

Overview

The Renesas Electronics Corporation 7133LA70J8 is a dual-port asynchronous static random-access memory (SRAM) integrated circuit. It provides a total storage capacity of 32 kbit, organized as 2K x 16 words. The device features a parallel interface with an access time of 70 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum power current of 250 mA. The component is housed in a 68-lead PLCC package with J-leads. It is designed for surface mount installation and functions reliably across an operating temperature range of -55°C to +125°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous access by two processors
• Asynchronous operation compatible with various system clock speeds
• Industrial-grade wide temperature range capability for harsh environments

Applications

• Embedded systems requiring high-speed data buffering
• Network equipment cache memory applications
• Industrial control systems with dual-processor architectures

Procurement Notes

Verify the specific suffix J8 against the official datasheet to confirm the 68-PLCC package type and lead configuration. Ensure compatibility with existing PCB footprints, as pinouts may differ from other packages in the 7133LA series. Confirm moisture sensitivity level requirements for reflow soldering processes. Check RoHS compliance status if environmental regulations apply to the final assembly. Validate that the 70 ns access time meets the timing constraints of the target application bus.

Selection Notes

Select this component when dual-port functionality is required for concurrent read/write operations between two masters. The 70 ns speed suits moderate-frequency asynchronous buses. Consider the 68-PLCC package availability and mounting method during design. Compare power consumption specifications against system thermal limits. Evaluate alternative packages like TQFP if space constraints or automated assembly preferences dictate a different form factor within the same memory family.

Part Context

This part belongs to the Renesas 7133LA series of dual-port SRAMs. The series offers various speed grades and packaging options to suit different performance and physical layout needs. The 7133LA70J8 specifically targets industrial applications due to its extended temperature range. It serves as a versatile memory solution for bridging processor speeds and managing data flow in complex embedded designs.

Replacement Considerations

Check for direct cross-reference parts such as IDT7133LA70J8. Verify pin-to-pin compatibility before substitution. Ensure the replacement maintains the 70 ns access time and 32 kbit capacity. Confirm package dimensions match the existing board layout.
