Product data sheet
7.14.1 Features
7.15.1 Features
7.16.1 Features
7.14 10-bit DAC
7.15 UARTs
7.16 SPI serial I/O controller
The DAC allows the LPC2377/78 to generate a variable analog output. The maximum
output value of the DAC is V
The LPC2377/78 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 115200
can be achieved with any crystal frequency above 2 MHz.
The LPC2377/78 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.
