System memory

Non-volatile memory optimized for advanced automotive markets such as ADAS Fujitsu Semiconductor Memory Solutions, Inc. has added the 2M-bit FeRAM "MB85RS2MLY," which operates at a low voltage of 1.8V, to its lineup of 125°C operating FeRAM family. This product is a memory with an SPI interface that operates at a low supply voltage of 1.7V to 1.95V. Evaluation samples are currently available, with mass production scheduled for June. This new product is ideal for electronic control units that require low voltage operation in advanced automotive markets such as advanced driver-assistance systems (ADAS). ■ Main Specifications Product Name: MB85RS2MLY Capacity (Memory Configuration): 2M bits (256K x 8 bits) Interface: SPI (Serial Peripheral Interface) Operating Frequency: 50MHz (maximum) Operating Supply Voltage: 1.7V to 1.95V Operating Temperature Range: -40°C to +125°C Write/Read Endurance: 10 trillion cycles (10^13 cycles) Package: 8-pin SOP, 8-pin DFN Quality Standards: AEC-Q100 Grade 1 compliant

Fujitsu Semiconductor Limited has developed the 8M-bit FeRAM "MB85R8M2T," which has the largest memory capacity in its FeRAM product lineup, and has started mass production this month. This product operates in a wide range of 1.8V to 3.6V and features a non-volatile memory with an SRAM-compatible parallel interface. It meets the demand for increased memory capacity beyond the previous maximum of 4M bits FRAM and addresses the requirement for reducing the battery used for power interruption measures in already deployed 8M-bit SRAM. By replacing the SRAM used in industrial applications such as control devices, robots, and machine tools with this FeRAM, it eliminates the need for batteries, reduces the mounting area of the memory section by approximately 90%, and contributes to overall cost reduction.

■Non-volatile memory for automotive and industrial machinery that guarantees reliability in high-temperature environments The “MB85RS4MTY” is a non-volatile memory with a doubled memory capacity of 4M bits and operates with an SPI interface at a wide power supply voltage range of 1.8V to 3.6V. Even in high-temperature environments of 125°C, the operating current is kept to a maximum of 4mA (at 50MHz operation), and the power-down current is a maximum of 30µA, contributing to low power consumption in environmentally conscious systems. ■Main specifications - Product name: MB85RS4MTY - Capacity (memory configuration): 4M bits (512K x 8 bits) - Interface: SPI (Serial Peripheral Interface) - Operating frequency: 50MHz (maximum) - Operating power supply voltage: 1.8V to 3.6V - Operating temperature range: -40°C to +125°C - Write/read guarantee cycles: 10 trillion cycles - Package: 8-pin DFN, 8-pin SOP
