Fujitsu FRAM holds a leading position in the global non-volatile memory market due to its exceptional performance and reliability. Since its mass production began in 1999, Fujitsu's FRAM products have been highly recognized for their ultra-high endurance of up to 10 trillion read/write cycles, fast write speed of 150 nanoseconds, non-volatile data retention, low power consumption, and a wide operating temperature range (-40°C to +85°C, with some models reaching +125°C). Because of these features, FRAM is widely considered an ideal storage solution for critical fields such as automotive electronics, smart cards, electricity meters, and medical devices.
MB85RS64T is a high-performance memory device in Fujitsu's FRAM product line, offering a storage capacity of 64Kbit organized logically as 8,192 words x 8 bits. This FRAM utilizes the Serial Peripheral Interface (SPI), supporting Mode 0 and Mode 3, with a maximum operating frequency of 10 MHz, ensuring efficient data transfer. MB85RS64T boasts extremely high read/write endurance, with each byte capable of withstanding up to 10^13 read/write operations, guaranteeing long-lasting and reliable operation. Additionally, it maintains data retention for at least 10 years at +85°C, operates with a supply voltage range of 1.8 V to 3.6 V, and supports low power consumption, with a maximum current of 0.8 mA during operation at 10 MHz and a typical standby current of 9 μA, making it highly suitable for battery-powered devices.
MB85RS64T has a broad operating temperature range, covering from -40°C to +85°C, demonstrating strong adaptability for various environments. It is available in an 8-pin plastic SOP and SON package, both of which comply with the RoHS standard, reflecting Fujitsu's commitment to environmental protection and ensuring product compatibility. The non-volatile storage characteristic of MB85RS64T allows it to retain data even in the event of a power outage, offering faster write speeds and higher read/write endurance compared to SRAM. Unlike Flash memory or EEPROM, FRAM's writing process does not require waiting time, making it excellent for applications that need frequent data updates.
In the field of smart meters, MB85RS64T is widely used for storing settings, configurations, and status data, ensuring secure data storage even in the event of power outages. Its high-speed writing feature facilitates real-time updates of meter data, while high read/write endurance is a crucial factor for ensuring long-term reliable operation. The low power consumption of FRAM is also suitable for battery-powered meters, helping to extend battery life. In the industrial control field, MB85RS64T plays a significant role in storing and updating operational parameters, fault records, and maintenance logs of equipment. FRAM's non-volatility ensures that critical data is not lost in the event of unexpected power outages, while its high-speed read/write capabilities support rapid data logging and processing. Moreover, FRAM's extensive operating temperature range allows it to adapt to various environmental conditions on the industrial site, providing a reliable data storage solution for a variety of applications.
