Working Principle
The operating principles of FM25L04B-DG are based on its couple of data input/output pins and its set of control pins. The main data pins, DI and DO, can be used to read and write data respectively. There are two additional control pins – powering pin VCC, and the Chip Select pin CS. To read data, the CS pin must be made low (by connecting it to GND), DI must be high and the DO pin will output the data. To write data, the CS pin must be remain low and DI must be connected to the data source. The data will then be written to the memory after a write delay.
FM25L04B-DG features various protection features like ECC (Error Correction Code), EEPROM endurance and data retention. This IC also features a wide range of operating temperatures – from 0°C to +70°C.
Conclusion
FM25L04B-DG is a fast and reliable memory IC which can be used for various embedded applications. It offers a wide range of protection feature and its data input and output pins make it easy to use. It is a great choice for embedded applications.
