I2C Fm+ & smart-card / USART interfaces
I2C Fast-mode Plus (Fm+) interface
The simple, two-wire format of the Inter-Integrated Circuit (I2C) bus gives
designers a quick, easy way to extend core functionality and add new
features while saving power and minimizing the PCB footprint. Invented
by Philips (the founder of NXP) more than 30 years ago, the I2C bus is now
a de facto worldwide standard. The Fast-mode Plus version supports
speeds up to 1 Mbit/s, and offers a sink capability that can be used to
support higher currents or longer distances.
Features
Supports 400 kbit/s Fast-mode (Fm) and 1 Mbit/s Fast-mode Plus (Fm+)
Easy to configure as master, slave, or master/slave
Programmable clocks enable versatile rate control
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 lets devices with different bit rates
communicate via one serial bus
Serial clock synchronization enables handshake mechanism to
suspend/resume serial transfer
Supports multiple address recognition and a bus monitor mode
Provides open-drain I/O pins conforming to the full specification

Smart-card interface (USART)
To support a wide range of communication interfaces, NXP integrates a
full-featured Universal Synchronous/Asynchronous Receiver/Transmitter
(USART). The USART can operate as a standard asynchronous-only
UART, or interface with a smart-card or infrared (IrDA) device. By
including a fractional baud-rate generator, the USART supports
standard baud rates with any clock frequency above 2 MHz, and thus
eliminates the need for value-specific crystals.
Features
Smart-card mode conforms to ISO7816 specification
Auto-baud capabilities and FIFO control mechanism enable
software flow control implementation
IrDA mode supports infrared communication
Supports RS-485/9-bit/EIA-485 mode
Built-in fractional baud-rate generator eliminates need for external
crystals of particular values
Supports synchronous mode
16-byte receive and transmit FIFOs
Register locations conform to 16C550 standard
Receiver FIFO trigger points at 1, 4, 8, and 14 bytes
