The PCF8593 is a CMOS clock/calendar circuit, optimized
for low power consumption. Addresses and data are
transferred serially via the two-line bidirectional I
2C-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.
