14. PN7462 family Interfaces

14.1 I2C Master Interface

The I2C bus is a simple two-wire bi-directional serial communication interface that is
intended for inter-IC communication over short distances. The I2C-bus uses only two
wires: a serial clock line (SCL) and a serial data line (SDA). Each device is recognized by
a unique address. The I2C master controller is one of two I2C controllers supported by
PN7462 family. The I2C slave controller is described in

Section 14.3.1.

14.1.1 I2C Master features:

•

Standard I2C compliant bus interface with open-drain pins.

•

Supports standard-mode, fast mode and fast mode plus (up to 1 MBds)

•

Supports I2C master mode only

•

Programmable clocks allowing versatile rate control

•

Clock stretching

•

7-bits and 10-bits I2C slave addressing

•

LDM/STM instruction support

•

Maximum data frame sizes up to 1024 bytes
