The remaining 5 connections are SCL, SDA, IRQ, ATTN, and SOUNDER. Depending on the specific application, each of these
control lines can be used by connecting them to a host system. In the most minimal system, the SCL and SDA must be connected
to a master I2C interface to communicate with the MPR083. All of the connections for the MPR083 are shown by the schematic
Figure 4. Recommended System Connections Schematic
Note that in this configuration the AD0 address line is tied high thus the slave address of the MPR083 0x4D. Alternatively the
address line can be pulled low if the host system needs the MPR083 to be on address 0x4C. This functionality can also be used
to incorporate two MPR083 devices in the same system.
2.3
Serial Interface
The MPR083 uses an I2C Serial Interface. The I2C protocol implementation and the specifics of communicating with the Touch
Sensor Controller are detailed in the following sections.
2.3.1
Serial-Addressing
The MPR083 operates as a slave that sends and receives data through an I2C 2-wire interface. The interface uses a serial data
line (SDA) and a serial clock line (SCL) to achieve bi-directional communication between master(s) and slave(s). A master
(typically a microcontroller) initiates all data transfers to and from the MPR083, and generates the SCL clock that synchronizes
the data transfer.
The MPR083 SDA line operates as both an input and an open-drain output. A pull-up resistor, typically 4.7k
, is required on SDA.
The MPR083 SCL line operates only as an input. A pull-up resistor, typically 4.7k
, is required on SCL if there are multiple
masters on the 2-wire interface, or if the master in a single-master system has an open-drain SCL output.
Each transmission consists of a START condition (Figure 5) sent by a master, followed by the MPR083’s 7-bit slave address plus
R/W bit, a register address byte, one or more data bytes, and finally a STOP condition.
