Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SCLK | input | Serial data shift clock, maximum frequency 30 MHz. |
| 2 | SIN | input | Serial data input for grayscale and dot correction data. |
| 3 | MODE | input | Mode selection pin; MODE = GND selects GS mode (192-bit width), MODE = VCC selects DC mode (96-bit width). |
| 4 | OUT0 | output | Constant-current LED driver output, 0 to 80 mA adjustable via IREF resistor with 6-bit dot correction. |
| 5 | OUT1 | output | Constant-current LED driver output, 0 to 80 mA adjustable via IREF resistor with 6-bit dot correction. |
| 6 | OUT2 | output | Constant-current LED driver output, 0 to 80 mA adjustable via IREF resistor with 6-bit dot correction. |
| 7 | OUT3 | output | Constant-current LED driver output, 0 to 80 mA adjustable via IREF resistor with 6-bit dot correction. |
| 8 | OUT4 | output | Constant-current LED driver output, 0 to 80 mA adjustable via IREF resistor with 6-bit dot correction. |
| 9 | OUT5 | output | Constant-current LED driver output, 0 to 80 mA adjustable via IREF resistor with 6-bit dot correction. |
| 10 | OUT6 | output | Constant-current LED driver output, 0 to 80 mA adjustable via IREF resistor with 6-bit dot correction. |
| 11 | OUT7 | output | Constant-current LED driver output, 0 to 80 mA adjustable via IREF resistor with 6-bit dot correction. |
| 12 | NC | unconnected | No internal connection. |
| 13 | NC | unconnected | No internal connection. |
| 14 | OUT8 | output | Constant-current LED driver output, 0 to 80 mA adjustable via IREF resistor with 6-bit dot correction. |
| 15 | OUT9 | output | Constant-current LED driver output, 0 to 80 mA adjustable via IREF resistor with 6-bit dot correction. |
| 16 | OUT10 | output | Constant-current LED driver output, 0 to 80 mA adjustable via IREF resistor with 6-bit dot correction. |
| 17 | OUT11 | output | Constant-current LED driver output, 0 to 80 mA adjustable via IREF resistor with 6-bit dot correction. |
| 18 | OUT12 | output | Constant-current LED driver output, 0 to 80 mA adjustable via IREF resistor with 6-bit dot correction. |
| 19 | OUT13 | output | Constant-current LED driver output, 0 to 80 mA adjustable via IREF resistor with 6-bit dot correction. |
| 20 | OUT14 | output | Constant-current LED driver output, 0 to 80 mA adjustable via IREF resistor with 6-bit dot correction. |
| 21 | OUT15 | output | Constant-current LED driver output, 0 to 80 mA adjustable via IREF resistor with 6-bit dot correction. |
| 22 | XERR | tri_state | Open-drain error output terminal; pulled LOW when LED open detection (LOD) or thermal error flag (TEF) is detected. |
| 23 | SOUT | output | Serial data output for cascading multiple devices or reading status information including LOD and TEF flags. |
| 24 | GSCLK | input | Reference clock for grayscale PWM control, maximum frequency 30 MHz. |
| 25 | TEST | input | Test pin; must be connected to VCC to ensure proper dot correction operation. |
| 26 | IREF | bidirectional | Reference current terminal with internal 1.24 V band-gap reference; sets maximum output current via external resistor. |
| 27 | VCC | power_in | Power supply voltage, operating range 3.0 V to 5.5 V. |
| 28 | NC | unconnected | No internal connection. |
| 29 | NC | unconnected | No internal connection. |
| 30 | GND | power_in | Ground connection. |
| 31 | BLANK | input | Blanking control; when HIGH disables all OUTn outputs and resets grayscale counter. |
| 32 | XLAT | input | Level-triggered latch signal; latches data from input shift register to GS or DC register depending on MODE pin state. |
| 33 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
