1.7 Memory Map
The RM48 family of MCUs have a large byte addressable address space. Table 1-1 shows the address
space of a RM48L952 microcontroller on the left with specific details of how each region is used by the
HDK on the right. By default, the internal memory sits at the beginning of the address space.
The SDRAM is mapped into CS0 space on the EMIF. CS[4:2] are used for synchronous memory for
example SRAM, NOR Flash, NAND Flash, and so forth.
1.8 Power Supply
The HDK board operates from a single +12 V external power supply connected to the main power input
(P1), a 2.5 mm, barrel-type plug. Internally, the +12 V input is converted into +1.2 V, +3.3 V and +5.0 V
using Texas Instruments swift voltage regulators and PTH power module. The +1.2 V supply is used for
the MCU core while the +3.3 V supply is used for the MCU's I/O buffers and other module on the board.
The +5.0 V supply is used for ADC power (second option) and USB VBUS.

Connectors
Before the board is shipped, the XDS100V2 port1 is configured as JTAG, and port2 is configured as SCI.
The CPLD on the board is also programmed to route the JTAG signals to the MCU.
There is a circuitry to detect the external JTAG emulator. If a device is plugged onto the header J4 and
J19, the DS1 LED will be turned on, and XDS100V2 JTAG is disabled.
2.2.6 P1, +5 V to +12 V Input
Connector P1 is the input power connector. This connector brings in +5 V to +12 V to the HDK board. This
is a 2.5 mm jack. Figure 2-5 shows this connector as viewed from the card edge.

Figure 2-5. +12 V Input Jack
2.2.7 J18, USB Host Connector
Connector J18 is a type-A USB host connector. The RM48L952 device supports two OHCI ports. OHCI0
signals are pinmuxed with SPI, NHET, and GIO, and so forth. To use OHCI0, the channel 1 of dip switch
S2 has to be set to “ON”. OHCI provides 5 V VBUS through power switch U12.
The second USB host connector is not populated. Its footprint is overlapped with J16.
2.2.8 J16, USB Device Connector
The RM48L952 device has one W2FC module for USB device. Connector J16 is a type-B USB device
connector. To use W2FC, the channel 3 of dip switch S2 has to be set to “ON”. Two different connectors
can be mounted at location J16. The default connector is USB host.
2.2.9 SCI Interface
The internal SCI on the RM48L952 device is connected to the second port of the XDS100V2. The
XDS100V2 USB driver makes the FT2232H second channel appear as a virtual COM port (VCP). This
allows the user to communicate with the USB interface via a standard PC serial emulation port.
2.2.10 Daughter Card Interface
The HDK provides expansion connectors that can be used to accept plug-in daughter cards. The daughter
card allows users to build on their EVM platform to extend its capabilities and provide customer and
application specific I/O. The expansion connectors are for all major interfaces including asynchronous
memory, peripherals, and A/D expansion.
There are three daughter card interfaces: J9, J10, J11. These connectors are described in Table 2-6.
