5.7 SDRAM Interface
The M53015EVB provides 64 Mbytes of on-board Mobile SDRAM (16bit x 32M Micron Mobile
SDRAM). On-board terminations are provided.
5.8 BDM and JTAG Interfaces — Processor
The M53015EVB provides a BDM (Background Debug Mode) and JTAG Connector (26-pin header), J37,
to give the end-user the ability to utilize the BDM/JTAG features of the MCF53015 processor. In addition,
the M53015EVB provides an on board USB to BDM interface, J48.
5.9 USB 2.0 Host and Device(OTG)
The MCF53015 Processor contains a USB OTG module. This module is USB 2.0 compliant. It supports
host and device modes, and provides an on-chip full-speed/low-speed transceiver. One mini-AB receptacle
(USB 2.0 OTG) is provided on the M53015EVB.
5.10 USB Host Module
The MCF53015 Processor contains a USB Host module. This module is USB 2.0 compliant. It supports
host mode only, and provides an on-chip full-speed/low-speed transceiver. One Type-A receptacle (USB
2.0 Host) is provided on the M53015EVB.
5.11 Interrupts
There are four external interrupt pins provided on the MCF53015. IRQ7_B is connected to push button
switch SW1 to provide a user driven ABORT signal. This signal is also connected to the LED D5 to denote
when this signal is asserted.
IRQ1_B and IRQ4_B are available on the University Breakout Connector, J1. IRQ6_B is available on pin
2 of J32. IRQ6_B is also used as the USB_CLKIN line.
5.12 Timers
The MCF53015 provides four 32-bit timers with DMA support. DT0 - DT3 are connected to LEDs D1 -
D4. They can be disconnected from the LEDs by removing jumpers H2 - H5.
5.13 DSPI
The DSPI Module on the MCF53015 is used in SPI bus interface mode to interface with a TI
TLV320AIC23B stereo audio CODEC.
5.14 SSI Port
The MCF53015’s SSI port is connected to the Audio input of the external stereo audio CODEC. These
pins are also available on the University Breakout Connector, J1. Additionally, these pins are muxed with
UART1 and through jumper options, can be connected to an RS232; line driver to be used as UART pins.

5.15 Smart Card Interfaces
The MCF53015 has two Smart Card interfaces, SIM0 and SIM1. An 8 pin SIM card socket is provided on
the M53015EVB and connected to SIM0. The SIM_P0_VEN pin is accessible on TP5 and the pins of the
SIM1 port are accessible through test points TP6 - TP10.
5.16 Internal Amplifiers and Voice CODEC
The MCF53015 contains a Voice-band audio codec with integrated speaker, microphone, headphone, and
handset amplifiers. The M53015EVB has an on-board speaker and on-board microphone that can be
interfaced to the internal voice CODEC and amplifiers. The microphone and speaker can also be connected
to an external stereo audio CODEC. The jumper setups for the various CODEC configurations are
described in the tables below:

5.17 Ethernet
The MCF53015 has 2 10/100 Ethernet MACs. On the M53015EVB these are each connected to National
Semiconductor DP83640 ethernet PHYs. A dual port Ethernet jack, P2, is provided. Ethernet Channel 1 is
connected to the upper port, while Channel 0 is connected to the lower port. Link, speed, and activity lights
are provided for each port. MAC addresses for each Ethernet port are labeled on the board. The DP83640
also supports IEEE 1588. These pins are provided on a 26 pin header, J2.
5.18 UARTs
The MCF53015 includes 3 UART modules. The M53015EVB provides one standard RS232 line driver
necessary to interface with RS232 connectors. This driver is connected to the DB9 connector J52 and
jumper options can connect the driver to either UART1 (muxed with the SSI port pins) or UART2
(dedicated). The board also supplies a USB-to-UART bridge to interface with the MCF53015’s UART0.
If using this option, a USB type B connector can be used to interface with an external device, instead of
the standard RS232 connector. Before using this connector, the Serial to USB bridge driver
“CP210x_VCP_Win2K_XP_S2K3.exe” should be installed. This driver can be found on the included
DVD. Once the driver is installed, the USB port will show up on your computer as a COM port and you
can communicate with it using any terminal program. You can view the Device Manager on your computer
to determine the assigned COM port. UART jumper configurations are described in the following tables:
