Product Information

MB85RDP16LX is a Data-Processing FRAM in a configuration of 2,048 words × 8 bits incorporating a 43-bit or 46-bit binary counter, where FRAM (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 FRAM 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.
