Controllers

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: Enumerates the communications protocols and/or standard interfaces that a device supports or implements.

Function: Defines the use case for the part.

Interface: Defines the communication protocols used to interact with the device.

Standards: Enumerates protocol, format, form factor, or similar standards with with a device conforms.

Voltage - Supply: The rated working voltage of a device, given as a range or as a maximum.

Current - Supply: 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’s 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.
