The EVBQE128 Evaluation Board has been designed for the evaluation, demonstration and debugging of the Freescale Flexis QE128 Microcontrollers (MC9S08QE128 and MCF51QE128). The EVBQE128 can be used as a standalone application or can be controlled by a host PC via its built-in microDART™ interface.
Features
1. An “MCU” section containing:
An 80-pin LQFP socket accepting either the MC9S08QE128 or the MCF51QE128 microcontroller
A crystal oscillator, a provision for a clock module, a provision for a connector for providing an external clock source, together with jumpers to select the clock source
A BDM connector for in-circuit debugging/programming with an external instrument
A female header connectors with all of the MCU signals
2. A power supply section containing:
A 12 V DC barrel input connector (2.1 mm)
A four-way micro terminal block for providing specific power supplies and voltage references to the microcontroller
A jumper to select the power supply source (USB bus or barrel connector)
A power on/off switch
3. A built-in “microDART INTERFACE” section (with the main circuitry mounted on the back of the board) which allows the host PC to communicate with the microcontroller through a standard USB interface. Jumpers are present to configure this module. Thanks to the microDART in-circuit debugging firmware, BDM commands are sent to the target microcontroller through the USB bus. Additionally, a virtual COM port is automatically available over the same USB connection. This virtual COM port can be used by standard terminal programs, like HyperTerminal, to send/receive serial characters to/from the target microcontroller.
4. An “I/O” section containing
A Reset push-button
Four additional push-button
One potentiometer
Eight dip-switches
A piezoelectric buzzer
A light sensor
A temperature sensor
Ten user LEDs
A circuitry for driving and external LCD
A series of jumpers to connect/disconnect the above controls to/from the microcontroller
5. An “RS-232” section containing two RS-232 connectors together with a jumper to enable the RS-232 communication
6. A “SERIAL SETTINGS” section containing jumpers to select communication options
