HT45B0K Description
This device is a panion 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.
HT45B0K Key Features
- Glueless slave SPI interface to Holtek's MCU USB (Universal Serial Bus) 1.1 Full-speed module
- 6 endpoints (endpoint 0 included)
- Access of the corresponding USB FIFO from the USB host
- USB suspend signal from the USB host
- USB resume signal from the USB host
- USB Reset signal from the USB host CMOS external clock input, CLKI, with frequency 6MHz/12MHz for the USB PLL clock 16-p
HT45B0K Applications
- CMOS output structure Connected to the external interrupt input of MCU A USB related interrupt will generate a low pulse signal on this line 3.3V regulator outp
