This Product Selection Guide contains information to help select products in the Application Specific Microcontrollers category on DigiKey.com
Application-specific microcontrollers are semiconductor devices that incorporate a processing unit (microprocessor), memory (EEPROM, EPROM, flash, SRAM, ROM, RAM, etc.), and some peripherals (clocks, converters, ports, timers, UARTS, etc.) into a single device. Applications include audio recorder/playback, authentication, automotive, battery monitor, BLDC controller, Bluetooth, embedded security, GPS, networking, and USB to name a few.
SelectionCharacteristics
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.
Applications: Application is the type of equipment or environment the device will be used in, typically they are tested and rated by a third party to ensure certain minimum standards for the application they are intended for.
Core Processor: Identifies the microprocessor or processor technology that serves as the primary computational engine for a board or device.
Program Memory Type: Indicates the non-volatile memory technology that is used for program storage and the capacity of that memory.
Controller Series: Describes which CPU core(s) that are being used in the deivce.
RAM Size: Indicates the amount of RAM (Random Access Memory) with which a device is equipped.
Interface: Indication of which interface(s) or protocol(s) are used by the device to communicate with other components in the system.
Number of I/O: Indicates the number of device pins that are capable of being used for general-purpose digital input/output functions.
Voltage - Supply: Typically represented by a range, this indicates the low and high voltage limits that one can expect in 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.
