RV-8063-C7
The RV-8063-C7 is soldered onto the Development Board.
Every pin is either accessible at test pins 1 – 8 or at the test vias situated around the device.
The following passive components are already soldered on the Board:
C1
10 nF
Decoupling capacitor between V
SS
and V
DD
R1
330 Ώ
Current limiting resistor for LED
LED green
Supply on, current consumption of the LED has to be considered
R2
10 kΏ
Protection resistor to prevent short-circuit between external CLKOE signal and Jumper
R3
10 kΏ
Pull-up resistor INT to V
DD

Description
Serial Data Input: When CE is LOW, input may float
Serial Data Output: Push-pull output; drives from V
SS
to V
DD
; is high-impedance when not driving.
Ground
Input to enable the CLKOUT pin. If CLKOE is active HIGH, the CLKOUT pin is in output mode
When CLKOE is tied to Ground, the CLKOUT pin is LOW.
Interrupt Output; open-drain; active LOW; requires pull-up resistor; Used to output alarm, minute,
half minute, countdown timer and compensation Interrupt signals
Power Supply Voltage
Clock Output; push-pull; controlled by CLKOE. If CLKOE is active HIGH, the CLKOUT pin drives
the square wave of 32.768 kHz, 16.384 kHz, 8.192 kHz, 4.096 kHz, 2.048 kHz, 1.024 kHz or 1 Hz
(Default value is 32.768 kHz). When CLKOE is tied to Ground, the CLKOUT pin is LOW
Serial Clock Input. When CE is LOW, this input may float
Chip Enable Input; when LOW, the interface is reset; may not be wired permanently HIGH
