GENERAL DESCRIPTION
The PCF8593 is a CMOS clock/calendar circuit, optimized for low power
consumption. Addresses and data are transferred serially via the two-line

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.
