topGeneral description
The PCF8593 is a CMOS clock/calendar circuit, optimized for low power consumption. Addresses and data are
transferred serially via the two-line bidirectional IC-bus. The built-in word address register is incremented
automatically after each written or read data byte. The built-in 32.768 kHz oscillator circuit and the first 8 bytes of
RAM are used for the clock/calendar and counter functions. The next 8 bytes may be programmed as alarm registers
or used as free RAM space.
