CD74HC40105M96G4 - Logic Memory FIFOs

The CD74HC40105M96G4 is an integrated circuit Logic Memory FIFOs which is an approach to high performance, low power, and efficient on-chip buffering. This type of FIFOs are designed to address a wide range of applications where data is temporarily stored while a slower system device, such as a microcontroller, retrieves it. The device can be seen as a glue logic that allows different subsystems to access data quickly and reliably in an efficient manner. The CD74HC40105M96G4 uses a single 9-bit wide register organized as 8-bits with a parity bit. The 9-bit word is organized as follows: 7-bit data, 1-bit parity bit, 1-bit enable/disable and 1-bit boolean invalid output. The device is organized as 8 FIFOs, each with 1024 location deep buffer, allowing for data buffering between faster and slower peripherals in applications such as A/D and D/A conversion. The logic FIFOs have three factors to consider when implementing into a design. First is the clock frequency of the FIFO, second the write access speed, and third the read access speed. The CD74HC40105M96G4 supports up to 3.0GHz clock frequency, up to 600M Hz write access speed, and up to 400M Hz read access speed. The CD74HC40105M96G4 features several features which ensure its reliability when implemented into designs. It features an optional fault-sense signal, as well as an on-chip parity recognition system which ensures data integrity. It also features a temperature compensation circuitry which ensures that the readings are accurate even in extreme temperatures. Additionally, the device also has static control circuit which allows for precise control of the clock frequency and timing. The application field for the CD74HC40105M96G4 is very significant. As the use of FIFOs within embedded systems have become more widespread, this FIFO is increasingly being used for applications such as encryption/decryption, D/A and A/D conversion, digital audio, digital signal processing, medical imaging, and many more.The operating principle of the CD74HC40105M96G4 is relatively simple. Most of the control and ownership information of the data is stored in a linear array. The FIFO will read what is written and vice-versa, hence it is capable of controlling the data transfer flow between two modules. It reads and writes the data using a flow-through mechanism. When reading, the device starts at the read pointer and stops at the write pointer. When writing, the device writes at the write pointer and increases the pointer location by one. The CD74HC40105M96G4 is a powerful and reliable integrated circuit which can be used in many applications where data needs to be transferred between different interfaces. It is fast, efficient and offers a wide range of features which make it suitable for many different types of applications. As a result, this device can be found in small embedded systems, digital audio, encryption/decryption, and many more applications where high speed and reliable data buffering is needed.
