EM Microelectronic-Marin SA has released the EM7602 32.768kHz clock oscillator, which is claimed to exhibit three times better thermal drift than conventional tuning fork crystals available in the market today.

The 4-pin device has a 3.6-by-8mm footprint and consists of a patented torsional tuning fork crystal and a low-power IC. The device also exhibits improved oscillator stability and low power consumption.

It is rated for operation over the 1.8V to 3.6V voltage range and the -40C to 85C temperature range. The device has a temperature drift of -0.012ppm/C? and draws 6?A at 3V.

The EM7602 is used as a general purpose clock generator in digital systems and is suited for electricity metering and automotive applications. It is also sold to component manufacturers in a chipset as an input clock driver for EM Real Time Clocks, to be used instead of quartz when better thermal stability is needed or as an add-on circuit to other microcontroller manufacturers.
