STMicroelectronics STCL132K
The STCL132K silicon oscillator devices are reliable, easy to use, 5-pin low-cost silicon oscillators developed primarily for microprocessor clock applications, display drivers or other system applications where tighter clock accuracy is not critical. The STCL132K silicon oscillator devices are equipped with chip enable input, offering an easy way to stop microprocessor clocking during a power saving mode while at the same time significantly reducing the oscillator current consumption.FEATURES
