| General description |
The EM7604 is an advanced low power CMOS circuit intended to be used together with a 32.768 kHz tuning fork crystal as a low frequency clock oscillator.
Except the crystal, no other external components are required. In order to achieve a high frequency accuracy, the matched crystals should have a ± 20ppm tolerance or tighter.
Very low power consumption is guaranteed over an extremely wide supply voltage and temperature range. The EM7604 is available in a small SOT23-6 package and is a completely lead free product.
