About This Manual
This document describes the board level operations of the RM48 Hercules™ Development Kit (HDK). The
HDK is based on the Texas Instruments RM48L952 Microcontroller. The RM48 HDK is a table top card
that allows engineers and software developers to evaluate certain characteristics of the RM48L952
microcontroller to determine if the microcontroller meets the designer’s application requirements as well as
begin early application development. Evaluators can create software to execute on board or expand the
system in a variety of ways.
Notational Conventions
This document uses the following conventions.
The RM48 HDK will sometimes be referred to as the HDK.
Program listings, program examples, and interactive displays are shown in a special italic typeface. Here
is a sample program listing:
• equations
• !rd = !strobe&rw

1.6 Basic Operation
The HDK is designed to work with TI’s Code Composer Studio and other third party ARM IDEs. The IDE
communicates with the board through the embedded emulator or an external JTAG emulator. To start,
follow the instructions in the Quick Start Guide to install Hercules-specific software. This process will install
all of the necessary development tools, documentation and drivers.
HDK Specifications
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.

Power Supply
There are multiple power test points on the HDK board. The three main test point pairs provide a
convenient mechanism to check the HDK’s current for each supply. Table 1-2 shows the voltages for each
test point and what the supply is used for.
