Preliminary data sheet
7.14.1 Features
7.15.1 Features
7.16.1 Features
7.14 10-bit ADC
7.15 10-bit DAC
7.16 UARTs
The LPC2478 contains one ADC. It is a single 10-bit successive approximation ADC with
eight channels.
The DAC allows the LPC2478 to generate a variable analog output. The maximum output
value of the DAC is V
The LPC2478 contains 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.
