Epson Toyocom announced the development of the RA-8565SA real time clock module with a built-in crystal unit for automotive and industrial machinery applications. The clock module is operating at high temperatures (up to 125°C). The module also uses an I2C-Bus interface to control reading and writing calendar and other data over minimal signal lines, creating a module with high system compatibility.

32.768 kHz built-in crystal unit (oscillating properties guaranteed): Frequency precision 5 ± 23 x 10-6
Interface: I2C-BUS interface F/S mode
32.768 kHz output function: Open drain output with output control function
Real time clock function: Clock / calendar function, automatic leap year adjustment function, alarm interrupt function, fixed cycle timer interrupt function
