3 / 29 page ISL12022MA 3 FN7575.1 July 9, 2010 12 SCL Serial Clock. The SCL input is used to clock all serial data into and out of the device. The input buffer on this pin is always active (not gated). It is disabled when the backup power supply on the VBAT pin is activated to minimize power consumption. 13 IRQ/FOUT Interrupt Output/Frequency Output (Default 32.768kHz frequency output). This dual function pin can be used as an interrupt or frequency output pin. The IRQ/FOUT mode is selected via the frequency out control bits of the control/status register. Interrupt Mode. The pin provides an interrupt signal output. This signal notifies a host processor that an alarm has occurred and requests action. It is an open drain active low output. Frequency Output Mode. The pin outputs a clock signal, which is related to the crystal frequency. The frequency output is user selectable and enabled via the I2C bus. It is an open drain output. The output is open drain and requires a pull-up resistor. 14 VDD Power Supply. Chip power supply and ground pins. The device will operate with a power supply from VDD = 2.7V to 5.5VDC. A 0.1µF capacitor is recommended on the VDD pin to ground. 1, 2, 3, 8, 18, 19, 20 GND Ground Pin.

Please refer to TB347 for details on reel specifications. 2. These Intersil plastic packaged products employ special material sets, molding compounds and 100% matte tin plate plus anneal (e3) termination finish. These products do contain Pb but they are RoHS compliant by exemption 7 (Pb in high melting temperature type solders, electronic ceramic parts (e.g. piezoelectronic devices)) and exemption 5 (Pb in glass of electronic components). These Intersil RoHS compliant products are compatible with both SnPb and Pb free soldering operations. These Intersil RoHS compliant products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020. 3. For Moisture Sensitivity Level (MSL), please see device information page for ISL12022MA. For more information on MSL please see techbrief TB363. |
