UPC8001 Datasheet | NEC

features a low 3 m A (TYP.) and 2.2 µA (TYP.) current consumption at normal operation and power-OFF, respectively. Its high-speed charge/discharge circuit enables fast power-ON/OFF switching. The µPC8001 boasts an extremely small size packaged in a 14-pin plastic shrink SOP, and low external capacitances of less than 0.01 µF, in addition to an on-chip RSSI output resistor, and is most suitable for high-density mounting.
