First-In, First-Out (FIFO) memory devices are used for short-term storage of digital information, with the retrieval of information occurring in the same order and sequence that the information was stored. Also called queue or buffer memories, they are commonly used for the exchange of information between separate devices, particularly in cases where data is generated and consumed at different rates or at slightly different points in time.
DigiKey Programmable: For verified products, DigiKey can program/flash your compiled code or configuration variables prior to shipping. For unverified products, please inquire with ProgCent.Techs@digikey.com
Memory Size: The amount of memory available on the chip for program storage.
Function: Describes the main function usage of the circuit or the logic input timing of the circuit, whether it is dependent on the clock signal (synchronous) or independent of the clock signal (asynchronous).
Data Rate: Characterizes the maximum rate at which information can be transmitted or received by a device. Does not necessarily refer to the throughput rate for user data, see device datasheets for further information.
Access Time: The time required for valid data to become available after issuance of a read command.
Voltage - Supply: Typically represented by a range, this indicates the low and high voltage limits which one can expect standard operation. Voltages outside this range may damage the device and other system components.
Current - Supply (Max): This represents the maximum current to which a device will meet its given specifications. Exceeding this current may damage the device and/or other system components.
Bus Directional: Characterizes the information flow a FIFO is designed to facilitate.
Expansion Type: Indicates suitability for expanding FIFO capacity by using multiple devices to increase data word length and/or the number of data words stored.
Programmable Flags Support: Indicates whether or not a device incorporates a status-signaling mechanism having some level of configuration.
Retransmit Capability: Indicates whether or not a device allows for data written to it to be read from it more than once.
FWFT Support: Indicates whether or not a part supports First Word Fall Through.
Operating Temperature: Recommended operating temperature, typically given in a range or as a maximum. Exceeding these temperatures may affect performance or damage the device and other system components.
Mounting Type: Indicates how the device is attached.
Package / Case: Indicates the type of protective case used on an electronic component to allow easy handling, installation, and protection. This selection was determined to be the closest industry standard applicable to the suppliers device packaging. Typically it is best to check the actual dimensions from the datasheet rather than depend on this terminology when designing your circuit.
Supplier Device Package: This is what the manufacturer calls the package of this device. They are manufacturer specific. It is typically best to use the actual dimensions from the datasheets rather than to go by this terminology when designing your circuit.
