Overview
MSC711xADS
• MPC8272 is the MSC711x host. The MPC8272 system bus connects to the MSC711x HDI.
• Host/Slave connection through the 16-bit HDI16 port; the HDI16 interface is accessible via a PCI
backplane multiplexed with PCI signals.
• 32-bit PCI host compatible.
• Host debug through a single JTAG connector supports both the MPC8272 and MSC711x
processors.
• Debugging via either one JTAG chain (MPC8272 and MSC711x device together) or two
independent JTAG connections (MPC8272 separate from the MSC711x device) through the
COP/JTAG connection or the parallel port command converter.
• Flash memory for stand-alone applications.
• Memory:
—8 MB Flash memory for the MPC8272 (16 bits wide).
—64 MB SDR SDRAM for the MPC8272 (64 bits wide).
—32 MB DDR SDRAM for the MSC711x device (32 bits wide).
• Communications ports/external connections (see Figure 1-2):
—10/100Base-T Ethernet port (MII/RMII) using Davicom DM9161 connected to the MSC711x
device.
—10/100Base-T Ethernet port using Davicom DM9161 connected to the MPC8272 device.
—T1/E1 TDM interface using PMC-Sierra PM4351 connected to the TSI.
—Two PSTN connections using Legerity Le78D110VC/Le77D11xVC (SLIC/SLAC) connected to the
TSI.
—H.110.
—RS-232 universal asynchronous receiver/transmitter (UART) port (9-pin D-connector attached to
the MPC8272).
—RS-232 port (pins) connected to a UART that is connected to the MSC711x device.
—OCE10/JTAG connector for the MSC711x device.
—Parallel port that includes a JTAG command converter connected to the MP8272 device.
—COP/JTAG connector for the MPC8272.
—High-density (MICTOR) logic analyzer connectors to monitor MSC711x signals
—6U PCI form factor.
• MSC711x devices boot through the HDI16 host port or the I
2
C port.
• After reset, selectable Debug Enable/Disable and Debug Request options.
• Board identification and board status read via the Board Control and Status Registers (BCSRx).
• Variant board configurations available via the dual-in-line package (DIP) switch setting.
• Push buttons for both the host and slave:
— Power-on reset.
— Soft reset.
— Hard reset.
— Abort.
• Time-slot interchanger (TSI) device connected to the TDM channels on the MSC711x processor;
used as the H110 framer and TDM master.
• SLIC-SLAC interface enables use of 6-line communication board with Voice-over-Broadband
SLIC/SLAC chip set.
• LEDs indicate power supply, peripheral enables, and software signals.
