Product data sheet
7.13.1 Features
7.14.1 Features
7.15.1 Features
7.13 10-bit DAC
7.14 UARTs
7.15 SPI serial I/O controller
The DAC allows the LPC2364/65/66/67/68 to generate a variable analog output. The
maximum output value of the DAC is V
The LPC2364/65/66/67/68 each contain four UARTs. In addition to standard transmit and
receive data lines, UART1 also provides a full modem control handshake interface.
The UARTs include a fractional baud rate generator. Standard baud rates such as
115 200 Bd can be achieved with any crystal frequency above 2 MHz.
The LPC2364/65/66/67/68 each contain one SPI controller. SPI is a full duplex serial
interface designed to handle multiple masters and slaves connected to a given bus. Only
a single master and a single slave can communicate on the interface during a given data
transfer. During a data transfer the master always sends 8 bits to 16 bits of data to the
slave, and the slave always sends 8 bits to 16 bits of data to the master.
