Memory IC Procurement Notes

Verify the specific suffix MN6TP against official STMicroelectronics documentation to confirm the exact package type and tape/reel specifications. Ensure the procurement channel provides valid RoHS compliance certificates. Cross-reference the part number with current datasheets to confirm availability of the industrial grade variant and correct operating voltage parameters before finalizing orders.

Memory IC Selection Notes

Select this component when a 4-Kbit capacity is sufficient for application requirements. The 2.5 V to 5.5 V supply range makes it suitable for both 3.3 V and 5 V logic systems. Consider the SOIC-8 package dimensions for PCB layout constraints. Verify that the 20 MHz SPI speed meets the system's timing requirements and that the industrial temperature range aligns with the operational environment.

Memory IC Part Context

This device belongs to the M950x0 family of serial EEPROMs, which includes 1-Kbit and 2-Kbit variants. The M95040 specifically provides 512 bytes of storage. The 'W' suffix typically denotes the 2.5 V to 5.5 V voltage range, distinguishing it from lower voltage variants like the 'R' series. This family is designed for applications requiring reliable, low-power non-volatile memory with simple serial interfaces.
