The integrated system controller eliminate s the need for complicated

software development and control. Operation is possible using simple

commands from a microcontroller. ROHM’s novel single-chip configuration

that combines a controller and audio decoder and utilizes commands from a

CPU greatly simplifies design compared with conventional 2- and 3-chip

systems by reducing the number of external components.

Both the BU9457KV and BU9458KV meet or exceed the most stringent

requirements for ESD resistance: ±6000V at the USB terminal, 15kV against

proximity (air) discharge (when used in conjunction with an external Zener

diode), and 8kV agains t direct (contact) discharge , providing superior

strength against surge noise, resulting in unsurpassed reliability.
