HT45B0F Description
The HT45B0F is microcontroller peripheral device to implement SPI-to-UART data conversions. The UART module can operate in full-duplex mode with an interrupt output capability to the host microcontroller. Possible application could include data munication networks between microcontrollers, low-cost data links between PCs and peripheral devices, portable and battery operated devices, factory automation and process...
