7142SA100C

Overview

The 7142SA100C is a dual-port static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It provides a storage capacity of 16 kilobits, organized as 2K words by 8 bits. The device utilizes an asynchronous parallel interface with a maximum access time and write cycle time of 100 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports a commercial operating temperature range from 0°C to 70°C. The component is housed in a 48-pin side-brazed DIP package designed for through-hole mounting.

Feature Summary

• Dual-port architecture enabling independent simultaneous access by two processors
• Asynchronous operation without requiring a system clock signal
• CMOS technology ensuring low power consumption during standby and active modes

Applications

• High-speed data buffering between microprocessors and peripherals
• Cache memory implementation in embedded control systems
• Data logging and temporary storage in industrial automation equipment

Procurement Notes

Verify the specific suffix 'C' against official Renesas documentation to confirm pinout compatibility and electrical specifications. Confirm RoHS compliance status as historical records indicate potential non-compliance for this series. Validate that the 48-SIDE BRAZED package matches the target PCB footprint requirements before procurement.

Selection Notes

Select this component when independent dual-processor access to shared memory is required without external arbitration logic. Ensure the design accommodates the 4.5V to 5.5V supply voltage constraints. Verify that the 100ns access speed meets the timing requirements of the host system bus.

Part Context

This part belongs to the 7142SA family of dual-port SRAMs. These components are designed for applications requiring high-speed data sharing between two masters. The family typically offers various access speeds and packaging options to suit different performance and board space requirements.

Replacement Considerations

Consult official Renesas discontinuation notices for approved substitute part numbers. Verify functional equivalence regarding pin configuration and voltage levels before substitution.
