LVCS12E128 - Low-Voltage HCS12 Controller Module with MC9S12E128 |
|
|
|
|
|
| |
The LVCS12 is an easy applicable, credit card-sized Controller Module, based on the 16-bit microcontroller family HCS12 by Motorola. The LVCS12 module provides an easy way to evaluate the microcontroller. It is a versatile tool for rapid prototyping and a very cost-effective, off-the-shelf solution for low- and mid-volume series applications.
The LVCS12 can be operated within a wide supply range from 3 to 5 volts. It is equipped with a powerful MC9S12E128 microcontroller unit (MCU) supporting bus clocks up to 25MHz. The device contains the 16-bit HCS12 CPU, 128KB of Flash memory, 8KB RAM and a large number of peripheral function blocks, such as SCI (3x), SPI, IIC, Timer, PWM, ADC, DAC and General-Purpose-I/Os. |

RTC, EEPROM & DAC included |
|
|
LVCS12 is equipped with a software-trimmable, high-accuracy real time clock. It provides time of day, calendar and alarm functions as well as automatic switch-over to a backup battery in case of a loss of main supply. The backup battery (3V LiMn cell) is mounted on-board.
Since the MC9S12E-series MCUs are not equipped with EEPROM, a serial memory device was added to provide 16 Kbit non-volatile memory space.
The two DAC outputs of the MCU can only drive very light loads. Therefore, each channel is equipped with an external operational amplifier in voltage follower configuration.

|
TwinPEEKs Monitor Program |
|
|
Each LVCS12 controller module is equipped with a special version of TwinPEEKs monitor software, which allows easy download and programming of Flash Memory - without needing additional hardware tools.
The monitor code resides in a write-protected Flash boot block (only 4KB). It can not be erased unintentionally.
The assembly language source code of TwinPEEKs is available on request (cost option).
|
|
In-System Programming/Debugging |
|
|
LVCS12 is equipped with a standard 6-pin BDM interface for in-system programming and debugging.
The Background Debug Mode (BDM) of the HC12/HCS12 MCUs provides a convenient way for debugging and in-system programming. HCS12 development tools include ComPOD12/StarProg, NoICE12 Remote Debugger and ICC12 ANSI-C Compiler.
