2.3Power Supply The on-board power supply circuitry allows various power supply configurations. This
|
|
gives the user the capability to power the devices in the 3V and in the 5V voltage range. |
2.3.1 |
Power Supply |
The power supply source can come from two different and exclusive sources: |
|
Sources |
either from the JACK PWR connector |
|
|
|
|
|
either from the 2-point sip EXT connector. |
2.3.1.1 |
JACK PWR |
The Jack power connector implemented on board is a female Jack connector with inter- |
|
Connector |
nal 2.1mm conductor. It requires a male JACK outlet with 2.1mm capability. |
No specific polarization is mandatory as on-board diode rectifier gives a protection against inadvertent polarization invertion.
When using the JACK power supply, the board is powered with a 5V voltage.

Hardware Description

|
Note: Do not mount more than one power supply source on AT89STK-11 Board. |
|
|
Note: There is a diode voltage level between the negative output of the power supply |
|
|
and the “GND”. This could introduce some voltage gap during measurement |
|
|
and instrumentation. |
|
2.3.1.2 External EXT |
The battery power connector implemented on board is a male two point SIP connector. |
|
connector |
It requires an external power cable with a female 2 points connector. |
|
|
When powered though this interface, polarization is mandatory as no protection is given |
|
|
on board. |
|
|
The EXT power supply circuitry support input supply from 2.7V up to 5.5V DC. |

|
Note: Do not mount more than one power supply source on board. |
|
|
Note: Keep SP1 closed when using the EXT input |
|

|
2.4 |
Reset |
To be compatible with Atmel microcontrollers which have (or not) its on-chip RESET cir- |
|
|
cuitry (c.f.microcontroller datasheet), the board provides a RESET signal witch can |
|
|
come from 2 different sources: |
2.4.1Power-on RESET The on-board RC network acts as power-on RESET.
is performed.
