General description

cmos

BQ3285LF is a low -power micro -processor peripheral equipment that provides a clock and 100 -year calibration, with alarm function and battery operation. This architecture is based on the BQ3285 RTC and has the following additional functions: century, low -voltage operation, 32.768kHz output, 126 additional CMOS bytes, two shadow registers of the last address used, and one month alarm that meets the ACPI RTC specifications.

32.768kHz output can be used to maintain power management exchange activities. Whenever VCC is valid, the output of BQ3285LF32KHz is always open. In the VCC standby mode, 32kHz is in a state of activation, while BQ3285LF usually consumes 100 Weire. In the interruption " mode
