04 July 2012 Real time clock modules are compatible with numerous power devices Epson has launched the RX-4035SA/LC and RX-8035SA/LC real time clock modules, designed to be compatible with primary batteries, secondary batteries, capacitors and various other power sources. While conventional real time clocks use an external special purpose power management ic to sustain operation of the clock in case the main power supply is cut off, these can sometimes cause battery power loss. To combat this issue, Epson's new devices have a built-in power source switching function, realising very low leakage current and voltage drops, while maximizing battery power. Also onboard is an event recorder function for retaining the current time of electrical devices even during system failures at night or any other inconvenient time. The event recorder is equipped with two event input terminal systems with built in chattering free circuits, enabling recordings of individual events ranging from years to seconds in length. In addition, the modules are equipped with dual alarms and clock output, realising clock power consumption for the SA package type of 350nA, and for the LC package type of 400nA. For clock accuracy, in normal temperature environments two different accuracy levels may be designated; within 13 seconds or one minute per month. The RX-4035SA/LC is compatible with SPI interface, while the RX-8035SA/LC is compatible with I2C-Bus interface. The company plans to begin accepting orders for the new products from the end of July.
