LPC2212/2214
16/32-bit ARM microcontrollers
6.9 10-bit ADC
The LPC2212/2214 each contain a single 10-bit successive approximation ADC with four
multiplexed channels.
6.9.1 Features
Measurement range of 0 V to 3 V.
Capable of performing more than 400000 10-bit samples per second.
Burst conversion mode for single or multiple inputs.
Optional conversion on transition on input pin or Timer Match signal.
6.9.2 ADC features available in LPC2212/2214/01 only
Every analog input has a dedicated result register to reduce interrupt overhead.
Every analog input can generate an interrupt once the conversion is completed.
The ADC pads are 5 V tolerant when configured for digital I/O function(s).
6.10 UARTs
The LPC2212/2214 each contain two UARTs. In addition to standard transmit and receive
data lines, the UART1 also provides a full modem control handshake interface.
6.10.1 Features
16 B Receive and Transmit FIFOs.
Register locations conform to 16C550 industry standard.
Receiver FIFO trigger points at 1 B, 4 B, 8 B, and 14 B.
Built-in fractional baud rate generator covering wide range of baud rates without a
need for external crystals of particular values.
Transmission FIFO control enables implementation of software (XON/XOFF) flow
control on both UARTs.
UART1 is equipped with standard modem interface signals. This module also
provides full support for hardware flow control (auto-CTS/RTS).
6.10.2 UART features available in LPC2212/2214/01 only
Compared to previous LPC2000 microcontrollers, UARTs in LPC2212/2214/01 introduce
a fractional baud rate generator for both UARTs, enabling these microcontrollers to
achieve standard baud rates such as 115200 Bd with any crystal frequency above 2 MHz.
In addition, auto-CTS/RTS flow-control functions are fully implemented in hardware.
Fractional baud rate generator enables standard baud rates such as 115200 Bd to be
achieved with any crystal frequency above 2 MHz.
Auto-bauding.
Auto-CTS/RTS flow-control fully implemented in hardware.
