7142SA55C

Overview

The Renesas Electronics Corporation 7142SA55C is a static random access memory (SRAM) component belonging to the 7142 series. It features an 8K-bit storage capacity organized as 1K x 8 bits. The device utilizes a parallel interface and operates with an access time of 55 ns. It supports a supply voltage range from 4.5 V to 5.5 V, with a maximum power consumption of 110 mA. The component is housed in a CDIP-SB-48 package and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Dual-port asynchronous SRAM architecture enabling independent simultaneous read/write operations on separate ports.

Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded processors
• FIFO buffer applications in industrial control equipment

Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance. Confirm package integrity for the CDIP-SB-48 housing. Check for end-of-life notifications or discontinuance alerts prior to procurement planning. Ensure supplier documentation matches the specific suffix requirements for the 7142SA55C variant.

Selection Notes

Select this component when dual-port functionality is required for concurrent data handling. The 55 ns access speed suits moderate-frequency asynchronous interfaces. Verify that the 4.5V to 5.5V operating voltage aligns with the system power rails. Consider the through-hole CDIP-SB-48 package constraints during PCB layout design.

Part Context

This part belongs to the Renesas 7142SA family of CMOS dual-port SRAMs. These devices are designed for applications requiring high-speed data transfer between two independent buses. The 7142SA55C specifically denotes the 55 ns speed grade within the 8K-bit capacity segment of this product line.

Replacement Considerations

IDT7142SA55CB is listed as an alias for this component. Verify pinout and electrical specifications compatibility before substituting with other 7142 series variants.
