This Product Selection Guide contains information to help select products in the Controllers category on DigiKey.com
Products in this family are used primarily to provide informatic connectivity between endpoints that employ differing communication protocols and/or signaling methods. Examples include devices that connect an I2C bus to a UART, USB to I2C, SPI, Ethernet, or UART, Ethernet MACs and PHYs, and others. Also included are devices used to establish multi-way connections using interfaces designed for point-to-point communications, such as USB hub controllers.
SelectionCharacteristics
DigiKey Programmable: For verified products, DigiKey can program/flash your compiled code or configuration variables prior to shipping. For unverified products, please enquire with ProgCent.Techs@digikey.com.
Protocol: Indication of which protocol(s) are used by the device to communicate with other components in the system.
Function: Indicates the usage the part was designed for.
Interface: Indication of which interface(s) are used by the device to communicate with other components in the system.
Standards: Enumerates protocol, format, form factor, or similar standards with which a device conforms.
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: Typically 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.
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.
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 use this terminology when designing your circuit.
