Name Use
6 PJ1 Connect DC jack Plug to connect an external DC block. Must be
used in conjunction with appropriate settings of
S1, JP1 and JP6 (see details above).
Power supply features are:
Voltage: 7 V min; 12 V max
Current: 400 mA
7 J11 No
Connect In-Circuit Emulator
connector This connector must be used when using an external
In-Circuit Emulator (
SIGNUM 8052 ADM51 ICE).
Refer to the Electrical Schematic for pin assignment.
8 J6 Connect USB connector Standard USB socket. Requires a standard USB
1.1 or 2.0 device cable to connect to a computer.
9 JP23 Inserted USB interrupt jumper Jumper allows the VBUS (after level conversion)
to connect to USR7 (configured for interrupt).
Remove this jumper if not needed and USR7 can
be used for another purpose.
10 JP20 Not
Inserted Jumper:
analog in Jumper will select between the VBUS or analog in
test point for the analog input. Using VBUS on the
analog input will free up the USR7 interrupt for
other uses. The analog input can be set up to use
the compare to detect when the USB cable is
inserted/removed.
11 P1 No
Connect DB9 RS232 female
socket This socket allows connection of an RS232 cable
to a computer. Use a crossed wires (RX/TX)
cable. The evaluation board has an on-board
level shifter (U7) to allow direct connection to a
computer.
Connection of a RS232 link is required when using
the
pre-downloaded application.
12 D2, D3, D4,
D5, D6, D7
LEDs:
Serial link activity and
four dedicated LED
pins. These LEDs (D2, D3) reflect the activity on the
serial link (RS232 or serial), and the others are
used for general purpose indicators without the
need for current limiting resistors.
•
D2 reflects the activity on the RX line (Data
going TO the 73S1215F)
•
D3 reflects the activity on the TX line (Data
coming FROM the 73S1215F)
•
D4 to D7 are the LED0-LED3 output pins .
13 U5 LCD Module On-board LCD module:
•
2 lines of 16 characters, each character dot
matrix is 5x7.
•
Includes an embedded
Hitachi HD44780 LCD
driver , controlled from the on-board 73S1215F
USR interface.
14 RV1 Adjustable resistor to
adjust LCD brightness Can be used to adjust the brightness of the on-
board LCD module.
