- 133 MHz operation = 532M bytes/sec bandwidth
FLASH Memory
A nonvolatile memory to store application programs, user data, logfiles, and
board configuration. The DSP by default bootloads its application program from the
Flash Memory. Permanently stored in the Flash are the D.Module2.BIOS functions
and the Setup Utility, a resident program for field updates via USB or RS232.
- 8 MBytes, uniform sector architecture
- 10 years data retention, 100000 erase and write cycles guaranteed
- hardware write protection for basic configuration and bootloader
- D.Module2.BIOS programming support

Real-Time Clock
- use for alarm and time-stamps
- options for battery backup and external power supply
UART and Asynchronous Serial Interfaces
Asynchronous serial communication interfaces are an industry standard
to communicate with process control equipment or a host computer, either
via point-to-point connections (RS232 or RS422), or via a network/bus
topology (RS485).
The D.Module2 Setup-Utility,
a field maintenance tool resident in the Flash
Memory, uses the RS232 or USB interface to communicate with any PC.
- Two UARTs, one RS232 and one RS422/485 line interfaces
- RS232: up to 230.4 kBaud, RS422: up to 3 MBaud
- receive and transmit Fifos
- automatic hardware (RTS/CTS) flow control on UART0
- Interrupt and DMA support, programmable Fifo trigger levels
- D.Module2.BIOS programming support
High-Speed USB Peripheral Interface
USB is used as a fast data link to a host PC to exchange data in realtime,
modify signal processing parameters, upload application program updates, etc.
The D.Module2 Setup-Utility,
a field maintenance tool resident in the Flash
Memory, uses the RS232 or USB interface to communicate with any PC.
- USB0: high speed (480M bps) USB2.0 peripheral OTG
- USB1: full-speed (12M bps) USB1.1 Host Controller (on EXP-Connector)
- Interrupt and DMA support
- on-board 5V generation for USB host mode
- D.Module2.BIOS programming support
EMC
Signal integrity and EMC radiation have been carefully considered
during the D.Module2 series design:
- power supply filter
- local filters for high-speed units
- controlled-impedance PCB and shielding
- optimized connector pinout minimizes signal current loop area
Local bus
The local bus decouples the asynchronous on-board peripherals from
the high-speed synchronous DRAM and the external bus interface.
Connectors
The D.Module2 uses industry standard IEEE1386 high-density connectors.
The boards are self-stacking without needing a backplane. A typical standalone
module stack consists of a DSP module, one or more data acquisition modules, and
an optional networking module.
These boards interconnect the top and bottom connectors 1:1 to route signals
and busses through the module stack. FPGA daugther cards can break this
connection to insert the FPGA into the signal processing chain, typically
between data acquisition and DSP.
Please click the connector on the module's top side for specific information.
100Base-Tx / 100Base-Fx Ethernet Interface
The TMS320C6747 built-in Ethernet Controller and external PHY,
with a 2-port switch, combined with the D.SignT.TCP/IP
zero-copy stack provide a high-speed communication and networking
interface with minimum DSP resource consumption.
Port0 is connected to on-board magnetics, Port1 can be used
with external magnetics or a Fiber Transceiver.
An evaluation license of the D.SignT.TCP/IP stack is
included with the DS.C6747 development base package.
For OEMs an unlimited OEM license is available.

- USB initialization and data transfer functions
- Flash Memory erase and write
- Bootloader
D.Module2.Setup Utility
The Setup-Utility is a field maintenance tool, permanently stored in the

tools or an in-circuit emulator.
The Setup Utility can be invoked manually at module reset/power-on or called at
any time from your application program.
