Additional Infomation About Product

Datasheet Real-Time Clock (RTC) series 2 I C BUS Serial Interface RTC with High-precision Oscillation Adjustment BU9873 Outline Important Characteristics The BU9873 is a CMOS real-time clock, which has a Time Keeping Voltage 1.45V to 5.5V built-in interrupt generation function. This product is Time Keeping Current 1 0.4A (Typ) 2 connected to the CPU via I C interface, and configured to (V =3V, Ta=+25C) DD perform serial transmission of time and calendar data to Time Keeping Current 2 1.0A (Max) the CPU. A high-precision oscillation adjustment circuit is (V =3V, Ta=-40C to +85C) DD also integrated, which is capable of adjusting time counts Power Supply Voltage 1.8V to 5.5V with digital method, and correcting deviations in the Access Frequency 1 100kHz (Max) oscillation frequency of the crystal oscillator. (VDD=1.8V to 2.5V) Access Frequency 2 400kHz (Max) (VDD=2.5V to 5.5V) Features Package W (Typ) x D (Typ) x H (Max) 2 Connected to the CPU via I C Interface Time (Hour Minute Second, Selectable 12-Hour and 24-Hour Mode Setting) Calendar (Year Month DayWeek) Periodic Interrupt Function SOP8 MSOP8 (Output from INTRB, Ranging from 1 Second to 1 5.00mm x 6.20mm x 1.71mm 2.90mm x 4.00mm x 0.90mm Month) Alarm Interrupt Function (Day-of-Week Hour Minute in Setting Format, Output from INTRB) Oscillation Halt Sensing Function SOP- J8 VSON008X2030 32.768 kHz Clock Output 4.90mm x 6.00mm x 1.65mm 2.00mm x 3.00mm x 0.60mm (Output from 32KOUT with Control Register) 30 Second Adjustment Function Automatic Leap Year Recognition up to the Year 2099 TSSOP-B8 Built-in Oscillation Stabilizing Capacitors (CG, CD) 3.00mm x 6.40mm x 1.20mm High-Precision Oscillation Adjustment Circuit Product structure: Silicon monolithic integrated circuit This product has no designed protection against radioactive rays w ww.rohm.com TSZ02201-0919AGZ00010-1-2 2013 ROHM Co., Ltd.
