4M-bit FeRAM "MB85R4M2T"

basic information

This product adopts a 44-pin TSOP package compatible with general-purpose SRAM, allowing applications that use SRAM requiring high-speed access for data recording, such as industrial machinery, business equipment, and medical devices, to replace their SRAM with this product without significantly changing the board design. Furthermore, since a battery for data retention is not required, it can contribute to reducing the board mounting area of the final product, lowering power consumption, and decreasing total costs.

Detailed information

• 

  Reduction of implementation area By replacing SRAM with this FeRAM in devices that were recording data using batteries, the battery for data retention becomes unnecessary. This makes it possible to reduce the implementation area of the memory section by more than 50%.

• 

  Reduction of power consumption (energy saving) In systems using SRAM, a data retention current continuously flows to maintain the memory data even when the main power supply of the device is turned off. Therefore, a power consumption of approximately 15μW occurs per hour, but in non-volatile memory FeRAM, that power consumption becomes zero.

• 

  Reduction of Total Cost By replacing with FeRAM, it contributes to the reduction of total costs, including development and operation of the memory section. During development, the cost can be reduced by eliminating the battery, which lowers component costs. Furthermore, assuming the equipment is used for several years, the operational costs associated with maintenance, such as regular battery replacements, securing battery inventory, and inspections, which were required when using SRAM, will also be unnecessary. Therefore, this battery-less solution can contribute to the reduction of total costs, combining both development and operational costs.
