HT45B0F Datasheet - 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-co.

HT45B0F Features

* Operating Voltage - Transmit and Receive Multiple Interrupt fCLKI= 12MHz: 2.0V~5.5V fCLKI= 16MHz: 2.7V~5.5V fCLKI= 20MHz: 4.5V~5.5V

* Glueless slave SPI interface to Holtek¢s MCU

* Full-duplex, Universal Asynchronous Receiver and - Transmitter (UART) communication - 8 or 9 bit char
