LPC122x
32-bit ARM Cortex-M0 microcontroller
Bidirectional data transfer between masters and slaves.
Multi-master bus (no central master).
Arbitration between simultaneously transmitting masters without corruption of serial
data on the bus.
Serial clock synchronization allows devices with different bit rates to communicate via
one serial bus.
Serial clock synchronization can be used as a handshake mechanism to suspend and
resume serial transfer.
The I
2
C-bus can be used for test and diagnostic purposes.
The I
2
C-bus controller supports multiple address recognition and a bus monitor mode.
7.13 10-bit ADC
The LPC122x contains one ADC. It is a single 10-bit successive approximation ADC with
eight channels.
7.13.1
Features
10-bit successive approximation ADC.
Input multiplexing among 8 pins.
Power-down mode.
Measurement range 0 V to V
DD(3V3)
.
10-bit conversion time of 257 kHz.
Burst conversion mode for single or multiple inputs.
Optional conversion on transition of input pin or counter/timer match signal.
Individual result registers for each ADC channel to reduce interrupt overhead.
7.14 Comparator block
The comparator block consists of two analog comparators.
7.14.1
Features
Up to six selectable external sources per comparator; fully configurable on either
positive or negative comparator input channels.
BOD 0.9 V internal reference voltage selectable on both comparators; configurable on
either positive or negative comparator input channels.
32-stage voltage ladder internal reference voltage selectable on both comparators;
configurable on either positive or negative comparator input channels.
Voltage ladder source voltage is selectable from an external pin or an internal 3.3 V
voltage rail if external power source is not available.
Voltage ladder can be separately powered down for applications only requiring the
comparator function.
Relaxation oscillator circuitry output for a feedback 555-style timer application.
Common interrupt connected to NVIC.
Comparator outputs selectable as synchronous or asynchronous.
