VSS (Pin 1): This pin is the ground pin, providing the reference voltage for all the pins. Address Pins (A0-A10, Pins 2-12): These are address input pins used to select a specific memory location within the chip. The FM24CL16B-GTR has a 16K x 16-bit address space, meaning it can address 16K locations, and each location stores 16 bits of data. VCC (Pin 13): This is the power supply pin, where the positive voltage (typically 3.3V or 5V) is applied. WE (Pin 14): The Write Enable pin is used to initiate write operations to the FRAM memory. When this pin is active, data can be written to the specified address. OE (Pin 15): The Output Enable pin is used to enable the output driver of the memory for reading data. When this pin is active, the memory can output data to the data bus. CS (Pin 16): The Chip Select pin is used to activate the memory chip for communication. When this pin is low, the memory is selected and can be accessed; otherwise, it is deselected. DQ0-DQ3 (Pins 17-20): These are the data input/output pins, used for transferring data to/from the memory during read or write operations. Each bit of data will be transferred using the corresponding DQ pin.Common FAQs for the FM24CL16B-GTR
