67025

Overview

The CMSR-67025V-25 is a dual-port static RAM manufactured by TEMIC, organized as 8192 words by 16 bits. It utilizes CMOS technology and features an asynchronous operation mode with a maximum access time of 25 ns. The device is housed in an 84-terminal plastic LCC package (PQCC84). It supports independent read and write operations through two separate ports with distinct control, address, and I/O pins. The memory density is 131072 bits, and it operates within a temperature range up to 70 °C.

Feature Summary

• Dual-port architecture enabling independent asynchronous access via separate control and data interfaces
• CMOS construction utilizing an eight-transistor memory cell design for low power consumption
• Automatic power-down capability managed by chip select signals to reduce standby current

Applications

• Stand-alone 16-bit dual port RAM systems
• Master/Slave configurations for 32-bit or wide data bus systems
• Memory systems requiring full-speed error-free operation without discrete logic

Procurement Notes

Verify the manufacturer origin, as this component was originally produced by TEMIC. Confirm compliance status, noting that specific listings indicate non-RoHS certification. Ensure the package type matches the required 84-pin LCC form factor and validate the access speed requirements against the 25 ns specification before procurement.

Selection Notes

Select this component when independent simultaneous access to memory locations is required without external arbitration logic. It is suitable for applications needing low-power CMOS SRAM with a 16-bit word width. Verify that the operating temperature range meets the system's thermal constraints and that the asynchronous interface aligns with the controller's timing requirements.

Part Context

This part belongs to the MATRA MHS M 67025 series of CMOS dual-port static RAMs. The series is characterized by its ability to function as either a standalone unit or in master/slave pairs. The specific suffix indicates the access speed and package variant within the broader family of high-density dual-port memories designed for complex data handling tasks.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing should focus on the MATRA MHS M 67025 series specifications and compatible dual-port SRAM architectures with similar pinouts and electrical characteristics.
