Detailed Description
The MAX6900 contains eight timekeeping registers,
burst address registers, a control register, an on-chip
32.768kHz oscillator circuit, and a serial 2-wire, I2C-
compatible interface. There are also 31 bytes, 8 bits
wide of SRAM on board. Time and calendar data are
stored in the registers in a binary-coded decimal (BCD)
format. Figure 1 shows an I2C-bus-compatible timing
diagram. Figure 2 shows the MAX6900 functional dia-
gram.
Real-Time Clock
The RTC provides seconds, minutes, hours, day, date,
month, and year information. The end of the month is
automatically adjusted for months with fewer than 31
