This Product Selection Guide contains information to help select products in the Controllers category on DigiKey.com
Memory controller products are used to mediate interactions between a device such as a microcontroller and external data storage devices, with the exact functionality offered varying depending on the intended use case. For example, some provide the necessary power monitoring and management facilities to allow conversion of a volatile memory to non-volatile, others provide a bridge between a standard USB interface and an array of NAND flash devices, while others provide functions that differ in other ways.
SelectionCharacteristics
Controller Type: The specific type or category of memory controller integrated into the IC.
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.
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 supplier 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.
