2 / 28 page 2 FN6659.2 June 23, 2009 Block Diagram Ordering Information PART NUMBER (Note) PART MARKING VDD RANGE (V) TEMP RANGE (°C) PACKAGE (Pb-free) PKG. DWG. # ISL12022IBZ* 12022 IBZ 2.7 to 5.5 -40 to +85 8 Ld SOIC M8.15 *Add “-T” suffix for tape and reel. Please refer to TB347 for details on reel specifications. NOTE: These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100% matte tin plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations). Intersil Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020. I2C INTERFACE CONTROL LOGIC ALARM FREQUENCY OUT RTC DIVIDER SDA BUFFER CRYSTAL OSCILLATOR POR SWITCH SCL BUFFER SDA SCL X1 X2 VDD VBAT IRQ/FOUT INTERNAL SUPPLY VTRIP SECONDS MINUTES HOURS DAY OF WEEK DATE MONTH YEAR USER SRAM CONTROL REGISTERS GND REGISTERS TEMPERATURE SENSOR FREQUENCY CONTROL Pin Descriptions PIN NUMBER SYMBOL DESCRIPTION 1X1 Crystal Input. The X1 pin is the input of an inverting amplifier and is intended to be connected to one pin of an external 32.768kHz quartz crystal. X1 can also be driven directly from a 32.768kHz source. 2X2 Crystal Output. The X2 pin is the output of an inverting amplifier and is intended to be connected to one pin of an external 32.768kHz quartz crystal. X2 should be left open when X1 is driven from external source. 3VBAT Backup Supply. This input provides a backup supply voltage to the device. VBAT supplies power to the device in the event that the VDD supply fails. This pin should be tied to ground if not used. 4GND Ground. 5SDA Serial Data. SDA is a bi-directional pin used to transfer serial data into and out of the device. It has an open drain output and may be wire OR’ed with other open drain or open collector outputs. 6SCL Serial Clock. The SCL input is used to clock all serial data into and out of the device. 7IRQ/FOUT Interrupt Output/Frequency Output. Multi-functional pin that can be used as interrupt or frequency output pin. The function is set via the configuration register. It is an open-drain output. 8VDD Power Supply. ISL12022 |
