PCA8565
Real time clock/calender
Rev. 01 — 31 March 2003
Product data
1.
General description
The PCA8565 is a CMOS real time clock/calendar optimized for low power
consumption. A programmable clock output, interrupt output and voltage-low detector
are also provided. All address and data are transferred serially via a two-line
bidirectional I
2
C-bus. Maximum bus speed is 400 kbit/s. The built-in word address
register is incremented automatically after each written or read data byte.
