SPRS342C – NOVEMBER 2006 – REVISED JUNE 2008

The peripheral set includes: 1 configurable video port; a 10/100 Mb/s Ethernet MAC (EMAC) with a

management data input/output (MDIO) module; an inter-integrated circuit (I2C) Bus interface; a

multichannel buffered serial port (McBSP0); a multichannel audio serial port (McASP0) with 4 serializers; 2

64-bit general-purpose timers each configurable as 2 independent 32-bit timers; 1 64-bit watchdog timer;

up to 111-pins of general-purpose input/output (GPIO) with programmable interrupt/event generation

modes, multiplexed with other peripherals; 1 UART with hardware handshaking support; 3 pulse width

modulator (PWM) peripherals; 1 high-end controller area network (CAN) controller [HECC]; and 2 glueless

external

memory

interfaces:

asynchronous

external

memory

interface

(EMIFA)

for

slower

memories/peripherals, and a higher speed synchronous memory interface for DDR2.

The DM6431 device includes a Video Processing Subsystem (VPSS) with a Video Processing Front-End

(VPFE) input used for video capture.

The Video Processing Front-End (VPFE) is comprised of a CCD Controller (CCDC). The CCDC is capable

of interfacing to common video decoders, CMOS sensors, and Charge Coupled Devices (CCDs).

The Ethernet Media Access Controller (EMAC) provides an efficient interface between the DM6431 and

the network. The DM6431 EMAC support both 10Base-T and 100Base-TX, or 10 Mbits/second (Mbps)

and 100 Mbps in either half- or full-duplex mode, with hardware flow control and quality of service (QOS)

support.

The Management Data Input/Output (MDIO) module continuously polls all 32 MDIO addresses in order to

enumerate all PHY devices in the system.

The I2C port allows DM6431 to easily control peripheral devices and/or communicate with host

processors.

The high-end controller area network (CAN) controller [HECC] module provides a network protocol in a

harsh environment to communicate serially with other controllers, typically in automotive applications.

The rich peripheral set provides the ability to control external peripheral devices and communicate with

external processors. For details on each of the peripherals, see the related sections later in this document

and the associated peripheral reference guides.

The DM6431 has a complete set of development tools. These include C compilers, a DSP assembly

optimizer to simplify programming and scheduling, and a Windows™ debugger interface for visibility into

source code execution.
