HT45B0K NSOP16

HT45B0K NSOP16 is a companion chip for microcontrollers to provide USB connectivity with the USB host. Six USB endpoints are supported with 8/8/8/64/8/64-byte FIFO for endpoint 0~5 respectively. An external interrupt output to the host MCU is used for inetrrupt-driven operation. However, the host MCU may also poll the status register to obtain the latest status if the interrupt is not used.The possible applications include low-cost data links for computers/peripherals, portable andbatt ery operated devices/instruments, factory automation and process control.
