GENERAL DESCRIPTION
NC ADD1/SDI/SEN0 ADD0/CSN/SEN1 DVSS DVSS DVDD DVDD DVDD SCL/SCLK/MOT1 SDA/SDO/MOT0 D0 D1 33 32 31 29 28 27 26 30 25 24 23 22 21 20 GPIO can be configured to open drain mode. Particularly, adjacent sensor suppression (ASS) function ensures only one channel active each time. The range of power is 2.6V ~ 5.5V. Low-power operation makes the CP2532/CP2528 ideal for battery-operated systems, such as multimedia portable product. The CP2532/CP2528 is specified over the -40℃ to +85℃ temperature range. 36 35 10 11FEATURES
