PIC32MX1XX/2XX/5XX 64/100-PIN FAMILY

18.0 INTER-INTEGRATED CIRCUIT

(I2C)

Note:

This data sheet summarizes the features

of the PIC32MX1XX/2XX/5XX 64/100-pin

family of devices. It is not intended to be

a comprehensive reference source. To

complement the information in this data

sheet, refer to Section 24. “Inter-

Integrated Circuit (I2C)” (DS60001116)

in the “PIC32 Family Reference Manual”,

which is available from the Microchip

web site (www.microchip.com/PIC32).

The I2C module provides complete hardware support

for both Slave and Multi-Master modes of the I2C serial

communication standard. Figure 18-1 illustrates the

I2C module block diagram.

Each I2C module has a 2-pin interface: the SCLx pin is

clock and the SDAx pin is data.

Each I2C module offers the following key features:

• I2C interface supporting both master and slave

operation

• I2C Slave mode supports 7-bit and 10-bit addressing

• I2C Master mode supports 7-bit and 10-bit

addressing

• I2C port allows bidirectional transfers between

master and slaves

• Serial clock synchronization for the I2C port can

be used as a handshake mechanism to suspend

and resume serial transfer (SCLREL control)

• I2C supports multi-master operation; detects bus

collision and arbitrates accordingly

• Provides support for address bit masking
