 DESCRIPTION

MB85RDP16LX is a Data-Processing FeRAM in a configuration of 2,048 words × 8 bits incorporating a 43-bit or

46-bit binary counter, where FeRAM (Ferroelectric Random Access Memory) is able to retain data without

using a back-up battery, can be used for 1013 read/write operations and takes no wait time to write data, using

the ferroelectric process and silicon gate CMOS process technologies for forming the nonvolatile memory cells.

MB85RDP16LX can be accessed via Serial Peripheral interface (SPI) or Dual SPI.

This Data-Processing FeRAM features short power up time, fast memory access and ultra-low power

consumption. Together with the 43-bit or 46-bit binary counter function, MB85RDP16LX fits perfectly into

energy harvesting and rotary encoder applications.
