Fujitsu FRAM: Automotive Electronics and Multi-Domain Applications

Fujitsu's Ferroelectric Random Access Memory (FRAM) technology leverages its high read/write endurance, ultra-fast write capability, low-power operation, non-volatility, and high reliability to demonstrate strong core competitiveness in automotive electronics, IoT, industrial automation, and medical devices. Fujitsu's FRAM products offer read/write endurance up to 10¹³ cycles, an ultra-fast write speed of just 150 nanoseconds, and power consumption 400 times lower than EEPROM. They also support multiple interfaces (such as I²C, QSPI) and a wide operating temperature range (-40°C to +85°C). Additionally, Fujitsu has further enhanced the performance and applicability of FRAM through technological innovations such as high-speed QSPI interfaces, radiation resistance optimization, and single-chip solutions. With growing market demand and continuous technological evolution, FRAM is expected to hold an important position in the future storage market, especially in applications that require low power consumption, high reliability, and fast response.

The MB85RC128APNF-G-JNERE1 is a 128Kb FRAM memory device packaged in an 8-pin SOP and compatible with the I²C interface. Operating at a 1 MHz clock frequency, the device has a working current of approximately 1.5 mA, a supply voltage range of 2.7V to 3.6V, and a standby current of about 10 μA. With a fast write speed of 900 nanoseconds and non-volatile storage capabilities, the chip can operate stably over a wide temperature range of -40°C to +85°C, making it suitable for low-power, high-reliability, and fast read/write applications.

The MB85RC128APNF-G-JNERE1 is highly favored for its low power consumption, fast write speed, and high endurance. In automotive electronics applications, it is an ideal storage solution. It can be used in automotive infotainment systems to store system configurations and user data; in Battery Management Systems (BMS) to record battery status, ensuring data is safely retained during power loss; to support the instant response of emergency call systems (eCall); and to record sensor data in real-time for vehicle monitoring and fault diagnosis. With the efficient data transfer capabilities of the I²C interface, the chip meets the strict requirements for reliability and performance in automotive electronic systems.
