Pin Descriptions Pin Number Pin Name Description 1CLK Serial Data Shift Clock 2SDI Serial Data Input 3MODE Mode Select input with internal pulldown MODE = GND: Selects greyscale mode (see Setting Greyscale Brightness on page 14) MODE = VCC: Selects dor correction mode (see Setting Dot Correction on page 13) 4:11 OUT0:OUT7 Constant-Current Outputs 0:7 14:21 OUT8:OUT15 Constant-Current Outputs 8:15 22 XERR Error Output 0 = LED open detection or overtemperature condition is detected. 1 = Normal operation. 23 SDO Serial Data Output 24 GSCLK Greyscale Clock. Reference clock for greyscale PWM control 26 IREF Reference Current Terminal 25, 27 VCC Power Supply Voltage 12,13,28 N/C This pins must not be connected 29 PD Power Down 0 = normal operation mode 1 = power down mode 30 GND Ground 31 OEN Blank Outputs 0 = OUTn outputs are controlled by the greyscale PWM control. 1 = OUTn outputs are forced off; the greyscale counter is reset. 32 LD Data Latch. The internal connections are switched by pin MODE. For LD (MODE = GND), the greyscale register receives new data. For LD (MODE = VCC), the dot correction register receives new data. 33 Thermal Pad Thermal Pad. This pin must be connected to GND to ensure normal operation. Thermal Pad 24 GSCLK 23 SDO 22 XERR 21 OUT15 20 OUT14 19 OUT13 18 OUT12 17 OUT11 8 OUT4 7 OUT3 6 OUT2 5 OUT1 4 OUT0 3 MODE 2 SDI 1 CLK AS1121 33 |
