With the expansion of the storm of cutting orders and prices for semiconductor chips, there has been an avalanche of quotations for microcontrollers (MCU), which were relatively stiff in price and in short supply. In particular, the price pressure on consumer applications locked by Taiwan factories is the greatest, and it has even spread the news that the product prices of the top five MCU factories in the world have halved. MCU has become another key chip that faces the pressure of price reduction after driving IC, some power management IC and CIS image sensors, revealing that the semiconductor market is in short supply and the fever goes down rapidly. After repeated orders were placed on the client side, recently, due to inflation, war, interest rate and other pressure, the demand was not as expected, and began to slash inventory and clear the price.
