2 Hardware Features
2.1 Demonstration Board Features
The DEMO908JL16 board features:
1.
An MCU section containing:
An MC68HC908JL16 microcontroller (in 32-pin SDIP package, already
programmed with a demo application—in addition, you can also use any other pin-
to-pin-compatible device);
One clock sources: a 9.8304 MHz crystal, selectable via the “OSC ENA”
jumper.
2.
A power supply section containing:
A 12 V DC Power Supply Input Connector;
Power input selection jumpers for selecting the input voltage input source:
o
12 V DC input connector;
o
USB connector;
o
I/O header connector.
3.
A built-in “USB TO MON08” section which allows the host PC to communicate with the
microcontroller through a standard USB interface. USB 2.0 is fully supported. When
using an external in-circuit debugger (via the “MON08” connector), the “USB TO
MON08” circuitry must be bypassed by removing all of the J402 jumpers.
4.
A Reset section containing a Reset push-button connected to the MCU Reset pin.
5.
An input section containing:
Two push-buttons together with jumpers to connect/disconnect them to/from the
PTA0 and PTA1 pins of the microcontroller;
A potentiometer, together with a jumper to connect/disconnect it to/from the
PTD3/ADC8 pin of the microcontroller.
6.
An output section containing two high-efficiency (low-current) LEDs together with two
jumpers to connect/disconnect them to/from the PTD4 and PTD5 pins of the
microcontroller.
