Fujitsu Semiconductor 4 Mb ReRAM MB85AS4MT memory

The Fujitsu Semiconductor 4 Mb ReRAM MB85AS4MT memory operates with a wide range of power supply voltage, from 1.65 to 3.6 V. It features a small average current in read operations of 0.2 mA at a maximum operating frequency of 5 MHz.

It is suitable for battery-operated wearable devices and medical devices such as hearing aids, which require high-density, low power consumption electronic components.

The package is a 209 mm 8-pin small outline package (SOP), pin-compatible with other non-volatile memory products.

Other features include serial peripheral interface, 1.2 million write cycles, write operating current of 1.3 mA (during write cycle time), data retention of 10 years up to 85°C, unlimited read cycles, standby current of 10 mA, sleep current of 2 mA, and write cycle time (256 B page) of 16 ms (with 100% data inversion).
