4 / 23 page  XR21V1410 4 1-CH FULL-SPEED USB UART REV. 1.0.0 NOTE: Pin type: I=Input, O=Output, I/O= Input/output, OD=Output Open Drain. SCL 12 I I2C-controller serial input clock. 1K pull-up resistor is required. An optional external I2C EEPROM can be used to store default configura- tions upon power-up including the USB Vendor ID and Device ID. If an EEPROM is not used, this pin can be used with the SDA pin to select the Remote Wake-up and Power modes. An external pull-up or pull-down resistor is required. See Table 1 Ancillary Signals LOWPOWER 2 O Low power status output. This pin is HIGH when the XR21V1410 is in the suspend mode. This pin is LOW when the XR21V1410 is not in the suspend mode. An external pull-up or pull-down resistor is required on this pin. This pin is sampled upon power-on to configure the polarity of the LOWPOWER output during suspend mode. An external pull-up resistor will cause the LOWPOWER pin to be HIGH during suspend mode. An external pull-down resistor will cause the LOWPOWER pin to be LOW during suspend mode. VCC 16 Pwr +3.3V power supply. All inputs are 5V tolerant. GND 1, 13 Pwr Power supply common, ground. Pin Description NAME 16-QFN PIN # TYPE DESCRIPTION |
