Working Principle

The FM25L04B-G device is a four-terminal serial EEPROM that uses an asynchronous three-volt, serial interface. The device consists of a Control Logic, EEPROM Array, and Control Gates. The EEPROM array consists of 512 x 8-bit of memory cell and 2 x 8 bits of control logic. The control logic provides support for instruction set, memory operations, and is also used for power management and other tasks.

The FM25L04B-G device is organized into pages, which are 256 byte units. The address required for any individual byte is the page address and a byte address within that page. Read and write operations occur one byte at a time through a single I/O pin (SDA). The device supports write protect and write protect all commands for EEPROM storage protection.

The FM25L04B-G device supports a dynamic range of read, write and erase operations. Program, erase and read operations are controlled through polynomial commands in the three-byte instruction set. The device provides 4Kbyte of data storage, which is organized as 16 pages of 256 bytes each. The device utilizes an advanced SPI protocol, supporting a dual SPI interface with a maximum communication speed of 5MHz.

The write protect command can be used to protect the EEPROM storage array from accidental write operations. The device also supports sector write protection and individual block unlock commands. The unlock command can be used to unlock a sector, which will enable the unlock bit to be set, making the sector writable.

The FM25L04B-G device supports an array of advanced features, including fast rising time, low standby current, wide voltage range, fast programming and erasing, sector write protection and individual block unlock. In addition, the device supports a fault detection system, which can detect write errors and alert the user. The device is highly reliable and can provide a long data retention time of up to 20 years.
