2.2 Power Supply

The on-board power supply electronics enable various power supply configurations.

The power source can be:

– VBus from USB interface (USB connector)

– An external power converter (9V DC connector)

– 9V Battery (9V BATT connector)

– Laboratory Power Supply (LAB PWR connector)

The power source selection is done by means of a jumper. The jumper must be set

accordingly with the selected power source. The input of laboratory power supply is not

controlled by the jumper. This source is directly applied to the input of the low drop

regulator.

Any power supply (including the Laboratory Power Supply) can be turned on/off by

using the red switch (POWER). Once the power is established, the power LED (PWR)

becomes red. A low drop regulator is used to deliver a 3.6V or a 5V voltage.

The low drop regulator can be bypassed by means of “REG. BYPASS” jumper. In this

case the power source is directly applied on the MCU. Extreme care must be taken in

using this feature and it is recommended to use it only with a Laboratory Power Supply

perfectly stable and controlled.

The demonstration board is protected by a fuse soldered on board. In case the fuse

blows, it is possible to bypass it by adding a solder gout on the solder pad next to the

fuse on the component side of the board until its replacement. Once the fuse is

replaced, the solder gout must be removed from the bypass pad.

2.2.1 Regulator Output

Voltage Selection &

Power On

The 3.6V output can be changed by means of R4 resistor (solder side). The output volt-

age equation is:

Vref = 1.20V, R3 = 1MΩ

2.3 C51 Settings

2.3.1 INT1 Switch The INT1 switch can be disabled by removing the solder gout from the solder pad SW36

on the solder side of the CPU demonstration board.

2.3.2 EA Jumper

2.3.3 ALE led The ALE led reports the MCU state. It can be disabled by removing the solder gout from

the solder pad SW4 on solder side of the board.

2.3.4 Reset The push button is provided to generate a warm reset.

2.3.5 Crystal The 8 Mhz crystal can be removed in order to be placed next to the appropriate package

(PLCC68 or PLCC28). The load capacitors are disabled by default because the internal

oscillator of the MCU has been designed to work without them. However these capaci-

tors can be enabled by adding a solder gout on the solder pads SW34 and SW35 on the

solder side of the board.
