1. Overview
The S12compact is a versatile controller module based on the
HCS12 16-bit microcontroller family from Motorola. It combines
compact size (Half-Euro form factor, 80mm x 100mm) with powerful
computing features and a rich set of peripherals. The controller module
can be used for a wide range of applications, e.g. industrial controllers,
measuring devices and data loggers.
The S12compact is equipped with a MC9S12DP512 microcontrol-
ler unit (MCU). It contains a 16-bit HCS12 CPU, 512KB of Flash
memory, 14KB RAM, 4KB EEPROM and a large amount of peripheral
function blocks, such as SCI, SPI, CAN, IIC, Timer, PWM, ADC and
General-Purpuse-I/Os. The MC9S12DP512 has full 16-bit data
paths throughout. An integrated PLL-circuit allows adjusting perfor-
mance vs. current consumption according to the needs of the user
application.
In addition to the on-chip controller functions, the S12compact
module provides a number of useful peripheral options: 16-bit
A/D-Converter and 16-bit D/A-Converter including precision voltage
reference, battery-backed Real Time Clock (RTC), USB-Interface and
2MB (16Mbit) extra memory using Serial Data Flash.
For the HCS12 microcontrollers, a wide range of software tools
(Monitors, C-Compilers, BDM-Debuggers) is available to accelerate the
development process.

2. Quick Start
As no one likes to read lengthy manuals, we will summarize the
most important things in the following section. If you need any additio-
nal information, please refer to the more detailed sections of this
manual.
Here is how you can start:
wPlease check the board for any damages due to transportation
wConnect the Controller Module via RS232 to a PC. The connec-
tion between S12compact (interface SCI0, connector X2) and
PC is simply made using the flat ribbon cable which is in the
box.
wOn the PC, start a Terminal Program. An easy to use Terminal
Program is OC-Console, which is available at no charge from
our Website!
wSelect a baudrate of 19200 Bd. Disable all hardware or software
protocols.
wConnect a (stabilized!) power supply, e.g. here:
wGround on X4 pin 70
w+5V on X4 pin 72
wCheck voltage and polarity before making the connection!
wOnce powered up, the Monitor program will start, display a
message and await your commands.
We hope you will enjoy working with the S12compact Controller
Module!
