1.2.9
Mini-FlexBus
A multi-function external bus interface called the Mini-FlexBus is provided on the device with basic functionality of interfacing
to slave-only devices with a maximum slave bus frequency up to 40 MHz in 1:2 mode and 80 MHz in 1:1 mode. It can be
directly connected to the following asynchronous or synchronous devices with little or no additional circuitry:
External ROMs
Flash memories
Programmable logic devices
Other simple target (slave) devices
The Mini-FlexBus is a subset of the FlexBus module found on higher-end ColdFire microprocessors. The Mini-FlexBus
minimizes package pin-outs while maintaining a high level of configurability and functionality.
1.2.10
USB On-The-Go Controller
The device includes a Universal Serial Bus On-The-Go (USB OTG) dual-mode controller. USB is a popular standard for
connecting peripherals and portable consumer electronic devices such as digital cameras and handheld computers to host PCs.
The OTG supplement to the USB specification extends USB to peer-to-peer application, enabling devices to connect directly
to each other without the need for a PC. The dual-mode controller on the device can act as a USB OTG host and as a USB
device. It also supports full-speed and low-speed modes.
1.2.11
Fast Ethernet Controller (FEC)
The Ethernet media access controller (MAC) supports 10 and 100 Mbps Ethernet/IEEE 802.3 networks. An external transceiver
interface and transceiver function are required to complete the interface to the media. The FEC supports three different standard
MAC-PHY (physical) interfaces for connection to an external Ethernet transceiver. The FECs supports the 10/100 Mbps MII,
and the 10 Mbps-only 7-wire interface.
1.2.12
UARTs
The device has three full-duplex UARTs that function independently. The three UARTs can be clocked by the system bus clock,
eliminating the need for an external clock source. On smaller packages, the third UART is multiplexed with other digital I/O
functions.
1.2.13
I2
The processor includes two I2C modules. The I2C bus is an industry-standard, two-wire, bidirectional serial bus that provides
a simple, efficient method of data exchange and minimizes the interconnection between devices. This bus is suitable for
applications requiring occasional communications over a short distance between many devices.
1.2.14
QSPI
The queued serial peripheral interface (QSPI) provides a synchronous serial peripheral interface with queued transfer capability.
It allows up to 16 transfers to be queued at once, minimizing the need for CPU intervention between transfers.
1.2.15
Fast ADC
The fast ADC consists of an eight-channel input select multiplexer and two independent sample and hold (S/H) circuits feeding
separate 12-bit ADCs. The two separate converters store their results in accessible buffers for further processing. Signals on the
SYNCA and SYNCB pins initiate an ADC conversion.
