The LPC2420/2460 contains one ADC. It is a single 10-bit successive approximation ADC
with eight channels.
The DAC allows the LPC2420/2460 to generate a variable analog output. The maximum
output value of the DAC is V
The LPC2420/2460 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
115 200 Bd can be achieved with any crystal frequency above 2 MHz.
