Fujitsu’s first product of a FRAM process die shrink is the MB85RS2MTA.
The chip is a 2 Mbit FRAM device with SPI interface.
Apart from the commercial benefits, IC offers a series of technical advantages. The maximum operating frequency has been increased from 25 MHz up to 40 MHz at 3 V supply.
The device consumes max 2.0 mA active current at 40 MHz. That is 1/5 of that of the legacy product at 25 MHz.
At standby mode, MB85RS2MTA consumes maximum 50 µA, which is 1/3 of the legacy product.
Sleep current is 10 µA.
The lower power performance of the device makes it ideal for IoT and wearable applications, where logging process takes place frequently, and where the power supply is extraordinarily limited.
As with Fujitsu FRAMs, thevMB85RS2MTA offers a high endurance of 1013 read/write cycles, a 10 years’ data retention at 85° C, as well as high speed and flexible write access.
MB85RS2MTA comes with a SOP 8pin package (150mil). The product is already in mass production.
