Catalyst semiconductor products for the bus to add a new 16 channel I2C/SMBus interface LED driver / flashing controller. CAT9552 can be programmed for up to 16 LED flash or on / off drive. The product is suitable for use by the flashing LED advertising sales signs and with on / off LED indicator of a variety of consumer or industrial equipment.
The CAT9552 contains an internal oscillator and two programmable on / off or flicker frequency timers, which can range from 0.02 seconds to 5.8 seconds. Compared with the traditional bus extender, built-in oscillator and a programmable timer structure to reduce the number of components of the whole system and can significantly reduce the I2C bus data flow. Another feature of CAT9552 is that ports that are not used as LED control can be used as an ordinary I/O port.
