Distributor Rutronik offers Fujitsu's new ultra-small 1Mbit SPI FRAM memory chip. It is the ideal solution for miniature, power-critical applications for the sensor and wearable markets.
This new 8-pin miniature chip (WL-CSP) represents a variant of the existing MB85RS1MT product. Compared with the standard SO8 chip found in the industry, the new WL-CSP chip (3.09×2.28×0.33mm) enables mounting area reduction by 77%, and device height reduction by 80% . With the release of this product, Fujitsu offers a 1 Mbit SPI FRAM memory chip with the smallest package technology in the industry.
While conventional non-volatile memories such as flash memory or EEPROM have a battery life of only 1 million write cycles, the MB85RS1MT FRAM device offers a battery life of 10 billion read/write cycles, enabling flexible storage of data records. real time data. It can be quickly and flexibly overwritten on each memory cell without any waiting time, which means much lower power consumption during writing. It also helps extend battery life, especially for sensor and wearable applications, which have frequent logging functions.
The MB85RS1MT device works with a voltage range of 1.8 V to 3.6 V, and in an operating temperature range of -40°C to +85°C. Guarantees data retention of up to 10 years at a temperature of 85°C.
