Memory IC Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature range. Ensure compatibility with existing system voltage levels and interface requirements before procurement. Confirm availability status as product lifecycles may change.

Memory IC Selection Notes

Select this component when a 256K x 16 organization is required with a 12ns access speed. Consider the 44-pin SOJ package constraints for PCB layout. Evaluate power consumption specifications against system thermal limits. Verify that the LVTTL input/output compatibility matches the host controller logic levels.

Memory IC Part Context

This part belongs to the IDT71V416 family of 4 Megabit static random-access memories. The family offers various speed grades and packaging options to suit different performance and form factor requirements. Renesas Electronics acquired the IDT product line, maintaining these specifications.

Memory IC Replacement Considerations

Check for direct substitutes within the IDT71V416 series such as the 10ns or 15ns variants if timing allows. Verify pin-to-pin compatibility with alternative manufacturers offering similar 256K x 16 SRAM devices in SOJ-44 packages.

Memory IC FAQ

What is the function of the BHE and BLE pins?

BHE (Byte High Enable) and BLE (Byte Low Enable) allow independent control over the upper and lower bytes of the 16-bit data word.

Is the IDT71V416VS12PHI8 synchronous or asynchronous?

It is an asynchronous SRAM, meaning it does not require a clock signal for operation.
