X1  
X1. The X1 pin is the input of an inverting amplifier. An external 32.768kHz quartz  
crystal is used with the X1288 to supply a timebase for the real time clock. The  
recommended crystal is a Citizen CFS206-32.768KDZF. Internal compensation circuitry is  
included to form a complete oscillator circuit. Care should be taken in the placement of the  
crystal and the layout of the circuit. Plenty of ground plane around the device and short  
traces to X1 are highly recommended. See Application section for more information.  
X2  
X2. The X2 pin is the output of an inverting amplifier. An external 32.768kHz quartz  
crystal is used with the X1288 to supply a timebase for the real time clock. The  
recommended crystal is a Citizen CFS206-32.768KDZF. Internal compensation circuitry is  
included to form a complete oscillator circuit. Care should be taken in the placement of the  
crystal and the layout of the circuit. Plenty of ground plane around the device and short  
traces to X2 are highly recommended. See Application section for more information.  
RESET RESET Output – RESET. This is a reset signal output. This signal notifies a host  
processor that the watchdog time period has expired or that the voltage has dropped  
below a fixed V  
threshold. It is an open drain active LOW output. Recommended  
TRIP  
value for the pullup resistor is 5K Ohms. If unused, tie to ground.

SDA  
Serial Data (SDA). SDA is a bidirectional pin used to transfer data into and out of the  
device. It has an open drain output and may be wire ORed with other open drain or open  
collector outputs. The input buffer is always active (not gated).  
An open drain output requires the use of a pull-up resistor. The output circuitry controls  
the fall time of the output signal with the use of a slope controlled pull-down. The circuit  
is designed for 400kHz 2-wire interface speed.

SCL  
Serial Clock (SCL). The SCL input is used to clock all data into and out of the device.  
The input buffer on this pin is always active (not gated).  
12  
PHZ/IRQ Programmable Frequency/Interrupt Output – PHZ/IRQ. This is either an output from  
the internal oscillator or an interrupt signal output. It is a CMOS output.  
When used as frequency output, this signal has a frequency of 32.768kHz, 100Hz, 1Hz  
or inactive.  
When used as interrupt output, this signal notifies a host processor that an alarm has  
occurred and an action is required. It is an active LOW output.  
The control bits for this function are FO1 and FO0 and are found in address 0011h of  
the Clock Control Memory map. See “Programmable Frequency Output Bits—FO1,  
FO0” on page 15..
