ROHM  MR45V032AMAZBATL  芯片, FERAM, 32KB, SPI, 8SOP

The is a nonvolatile 32kB Ferroelectric Random Access Memory FeRAM with 4096-word x 8-bit configuration. It is developed in the ferroelectric process and silicon-gate CMOS technology. The MR45V032A is accessed using serial peripheral interface. Unlike SRAMs, this device, whose cells are nonvolatile, eliminates battery backup required to hold data. This device has no mechanisms of erasing and programming memory cells and blocks, such as those used for various EEPROMs. Therefore, the write cycle time can be equal to the read cycle time and the power consumption during a write can be reduced significantly. The MR45V032A can be used in various applications, because the device is guaranteed for the write/read tolerance of 10¹² cycles per bit and the rewrite count can be extended significantly.
