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 character length Even, odd or no parity options One or two stop bits Baud rate generator with 8-bit prescaler Parity, framing, noise and overrun error detection Support for interrupt on address detect Address Detect Interrupt - last character bit=1 Transmitter and receiver enabled independently 4-byte deep FIFO receiver data buffer Generation Sources: ¨ Transmitter Empty ¨ Transmitter Idle ¨ Receiver Full ¨ Receiver Overrun ¨ Address Mode Detect - TX pin is high impedance when the UART transmit module is disabled - RX pin is high impedance when the UART receive module is disabled
● CMOS clock input, CLKI, up to 20MHz at 5V operating voltage
● 16-pin NSOP package
