This Product Selection Guide contains information to help select products in the Configuration PROMs for FPGAs category on DigiKey.com
Configuration PROMs (Programmable Read-Only Memory) are companion devices to FPGAs, used to store a user’s desired configuration for the latter during periods when the device is powered down. The specific memory technology used varies and includes types which can be electrically erased and re-written, rendering their characterization as “read-only” devices somewhat anachronistic.
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.
Programmable Type: The method or technology used to store the configuration data that defines the logic and functionality of the FPGA
Memory Size: Indicates the amount of memory available on the device.
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 : Indicate 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.
