PIN DESCRIPTION
PIN
NAME
FUNCTION
1
VCC2
Primary Power-Supply Pin in Dual Supply Configuration. VCC1 is connected to a
backup source to maintain the time and date in the absence of primary power. The
DS1302 operates from the larger of VCC1 or VCC2. When VCC2 is greater than VCC1 +
0.2V, VCC2 powers the DS1302. When VCC2 is less than VCC1, VCC1 powers the
DS1302.
2
X1
3
X2
Connections for Standard 32.768kHz Quartz Crystal. The internal oscillator is
designed for operation with a crystal having a specified load capacitance of 6pF.
For more information on crystal selection and crystal layout considerations, refer to
Application Note 58: Crystal Considerations for Dallas Real-Time Clocks. The
DS1302 can also be driven by an external 32.768kHz oscillator. In this
configuration, the X1 pin is connected to the external oscillator signal and the X2 pin
is floated.
4
GND
Ground
5
CE
Input. CE signal must be asserted high during a read or a write. This pin has an
internal 40k
Ω (typ) pulldown resistor to ground. Note: Previous data sheet revisions
referred to CE as
RST. The functionality of the pin has not changed.
6
I/O
Input/Push-Pull Output. The I/O pin is the bidirectional data pin for the 3-wire
interface. This pin has an internal 40k
Ω (typ) pulldown resistor to ground.
7
SCLK
Input. SCLK is used to synchronize data movement on the serial interface. This pin
has an internal 40k
Ω (typ) pulldown resistor to ground.
8
VCC1
Low-Power Operation in Single Supply and Battery-Operated Systems and Low-
Power Battery Backup. In systems using the trickle charger, the rechargeable
energy source is connected to this pin. UL recognized to ensure against reverse
charging current when used with a lithium battery. Go to
