CY14B104N-BA45XC is a type of non-volatile memory and belongs to the family of CMOS serial electrically erasable programmable read-only memories (EEPROMs). It is designed to store information that needs to be stored even when the power is off. The memory has various features, such as a low current draw, a high-speed operation, three-state operation, an CE# device reset and a minimal pin count. It is a very popular choice for embedded applications such as those used in microcontrollers, industrial computers and medical devices.

The CY14B104N-BA45XC utilizes a 4-wire SPI protocol. This is a faster and more reliable bus than the more traditional Parallel bus. One major difference is that the address and data lines associated with a parallel bus are replaced with a single Serial Data input line. The interface is also reduced to 4 pins instead of the traditional 8 pins. The Address, Data, Clock and Chip Enable (CE#) pins are then used to transfer information both to and from the memory.

The Chip Enable pin is used to buffer the chip from active operation during a read or write cycle. When the CE# pin is high, the chip is enabled and data can be read or written from it. When the CE# pin is low, the chip is disabled and it resumes waiting for commands. This Addressed Data Transmission feature allows for the transfer of small blocks of data that can be addressed by the CE# pin.

The CY14B104N-BA45XC also has a dual power feature. It runs on a 3.3V and a 5V supply. This allows the device to be used in applications that have access to both power sources. It also allows the device to be used in low-voltage devices that cannot access a higher voltage. Additionally, it is part of the CYPRESS architecture which includes parts that have additional features such as error correction code (ECC) capabilities, encryption and other security measures.

The working principle of the CY14B104N-BA45XC is based on a simple concept. The device is divided into two parts, the logic array and the array of memory cells. The logic array helps to interpret the address and determine if it is a read or write cycle. The memory cells store the data bits and the logic array interprets the commands sent to the memory and sets up the read or write cycle. When a read cycle is initiated, the logic array sends out the address of the cell to be read and doses the voltage on the memory cells to determine the value stored in that cell. In a write cycle, the logic array doses the voltage on the memory cells with the data to be written, to store the data in the memory cell.

CY14B104N-BA45XC memory can be used in a variety of applications. It is very popular for embedded applications, such as those found in microcontrollers and industrial computers. Additionally, due to its small size, low power consumption and fast write times, it is also a popular choice for medical devices and other applications that require a low-power and small size non-volatile memory.
