Frequently asked questions
Does the eol_hot status mean the part is only available in full reels, or can I order Cut Tape quantities?
Cut Tape (CT) is still listed as an available packaging option alongside Tape & Reel (TR), so small-quantity orders in the 250-unit range are technically feasible. However, eol_hot status means the stocking position is finite — CT availability depends on what the distributor has broken out of reel stock, and replenishment of CT quantities is not guaranteed.
What is the maximum sustained supply current at 180MHz and does the part require derating below 3.6V?
Maximum sustained supply current at 180MHz under thermal load is not listed in the available ledger entries. The 1.7-3.6V operating supply range is specified; derating behaviour at the upper supply rail under sustained high-frequency operation requires consultation of the ST datasheet for the STM32F446xE product family.
