实时时钟电路, 日期时间格式 BCD 12Hr/24Hr, 并联, 4.5 V至5.5 V, LCC-28
The is a Real-time Clock intended for use in microprocessor based systems where information is required for multi-tasking, data logging or general time of day/date information. This device is implemented in low voltage silicon gate microCMOS technology to provide low standby power in battery back-up environments. The circuits architecture is such that it looks like a contiguous block of memory or I/O ports organized as one block of 32 bytes. This includes the control registers, the clock counters, the alarm compare RAM and the time save RAM. Time and date are maintained from 1/100 of a second to year and leap year in a BCD format, 12 or 24-hour modes. Day of week and day of month counters are provided. Time is controlled by an on-chip crystal oscillator requiring only the addition of the 32.768kHz crystal and two capacitors. Power failure logic and control functions have been integrated on chip.
