Pin Descriptions Pin Number Pin Name Description SSOP QFN 124:27 GND Ground 228 SDI Serial Data Input 31 CLK Serial Data Clock. The rising edge of the CLK signal is used to clock data into and out of the AS1110 shift register. In error mode, the rising edge of the CLK signal is used to switch error modes. 42 LD Serial Data Load 5:20 3:10 12:19 OUTN0:15 Output Current Drivers. These pins are used as LED drivers or for input sense for diagnostic modes. Data is transferred to the data register at the rising edge of these pins. 21 20 OEN Output Enable. The active-low pin OEN signal can always enable output drivers to sink current independent of the AS1110 mode. 0 = Output drivers are enabled. 1 = Output drivers are disabled. 22 21 SDO Serial Data Output. In normal mode SDO is latched out 8.5 clock cycles after SDI is latched in. In global error detection mode this pin indicates the occurrence of a global error. 0 = Global error mode returned an error. 1 = No errors. 23 22 REXT External Resistor Connection. This pin connects through the external resistor (REXT) to GND, to setup the load current. 24 23 VDD Positive Supply Voltage -11 N/C Not connected 1 AS1110 24-pin SSOP 24 2 3 4 5 23 22 21 17 8 7 6 20 19 18 9 13 12 11 10 16 15 14 SDO 10 21 OUTN13 17 8 CLK 1 OUTN0 3 OUTN4 7 AS1110 28-pin QFN 5x5 OUTN2 5 12 14 OUTN11 15 OUTN15 19 OEN 20 OUTN14 18 OUTN12 16 LD 2 OUTN1 4 OUTN3 6 13 11 9 26 28 24 22 23 25 27 |
