HT45B0F - Holtek Semiconductor

HT45B0F SPI-to-UART Bridge

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 communication networks between microcontrollers, low-cost data links between PCs and peripheral devices, portable a.
