Optimal for industrial machinery requiring reliable operation in extremely cold environments. Fujitsu Semiconductor Limited has developed the 64K-bit FeRAM "MB85RS64TU," which guarantees operation in extremely low temperature environments of -55°C, and is offering mass-produced products. This product features a wide operating voltage range of 1.8V to 3.6V and is a non-volatile memory capable of lower temperature operation than competing memories. It guarantees 10 trillion data rewrite cycles even at -55°C, making it particularly suitable for industrial machinery such as field devices used in the extraction of natural gas and oil in extremely cold regions. This FeRAM can also be utilized in general industrial fields such as measurement instruments, flow meters, and robots. <Main Specifications> Product Name: MB85RS64TU Capacity (Memory Configuration): 64K bits (8K x 8 bits) Interface: SPI (Serial Peripheral Interface) Operating Frequency: Up to 10MHz Operating Supply Voltage: 1.8V to 3.6V Operating Temperature Range: -55°C to +85°C Write/Read Guarantee Cycles: 10 trillion (10^13 cycles) Package: 8-pin SOP, 8-pin SON
