Product data sheet
6.7.1 Features
6.8.1 Features
6.9.1 Features
6.10 USB 2.0 device controller (LPC2158 only)
6.8 10-bit ADC
6.9 10-bit DAC
The LPC2157/2158 contain two single 10-bit successive approximation ADCs. While
ADC0 has eight channels (six channels for LPC2158), ADC1 has eight channels.
Therefore, the total number of available ADC inputs for LPC2157 is 16 and for LPC2158 is
14.
The DAC enables the LPC2157/2158 to generate a variable analog output. The maximum
DAC output voltage is the VREF voltage.
The USB is a 4-wire serial bus that supports communication between a host and a
number (127 max) of peripherals. The host controller allocates the USB bandwidth to
attached devices through a token based protocol. The bus supports hot plugging,
unplugging, and dynamic configuration of the devices. All transactions are initiated by the
host controller.

Mask registers allow treating sets of port bits as a group, leaving other bits
unchanged.
All GPIO registers are byte addressable.
Entire port value can be written in one instruction.
Bit-level set and clear registers allow a single instruction set or clear of any number of
bits in one port.
Direction control of individual bits.
Separate control of output set and clear.
All I/O default to inputs after reset.
10-bit successive approximation ADC.
Measurement range of 0 V to VREF (2.0 V
Each converter capable of performing more than 400000 10-bit samples per second.
Every analog input has a dedicated result register to reduce interrupt overhead.
Burst conversion mode for single or multiple inputs.
Optional conversion on transition on input pin or timer match signal.
Global Start command for both converters.
10-bit DAC.
Buffered output.
Power-down mode available.
Selectable speed versus power.
