AiP650EOSA16.TR

Wuxi I core Elec · LED Drivers · SOP-16

AiP650EOSA16.TR from Wuxi I core Elec, in a SOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 DIG1 output LED digit driver output, active low for display, which doubles as the active-high keyboard scan output; the datasheet limits DIG sink current to 0-150 mA and recommends a 2K series resistor between DIG1-DIG4 and the key matrix.
2 CLK input Two-wire serial interface clock input with an internal pull-up (typ. 550 uA); VIL max is 0.8 V and VIH min is 2.0 V.
3 DIO bidirectional Two-wire serial data input/output with an internal pull-up in open-drain mode (typ. 550 uA); VIL max is 0.8 V and VIH min is 2.0 V, and data must not change while CLK is high.
4 GND power_in Ground reference for the device; the datasheet recommends a 104 (100 nF) decoupling capacitor between VDD and GND placed within 2 cm of the VDD pin.
5 DIG2 output LED digit driver output, active low for display, which doubles as the active-high keyboard scan output; the datasheet limits DIG sink current to 0-150 mA and recommends a 2K series resistor between DIG1-DIG4 and the key matrix.
6 DIG3 output LED digit driver output, active low for display, which doubles as the active-high keyboard scan output; the datasheet limits DIG sink current to 0-150 mA and recommends a 2K series resistor between DIG1-DIG4 and the key matrix.
7 DIG4 output LED digit driver output, active low for display, which doubles as the active-high keyboard scan output; the datasheet limits DIG sink current to 0-150 mA and recommends a 2K series resistor between DIG1-DIG4 and the key matrix.
8 A/KI1 bidirectional LED segment A driver output, active high (max 30 mA per segment), which also serves as key-scan input KI1 with an internal pull-down; KI high input min is 1.8 V and low input max is 0.5 V.
9 B/KI2 bidirectional LED segment B driver output, active high (max 30 mA per segment), which also serves as key-scan input KI2 with an internal pull-down; KI high input min is 1.8 V and low input max is 0.5 V.
10 VDD power_in Supply pin, 3 V to 5.5 V operating (absolute maximum 6.5 V); a 104 decoupling capacitor should be placed as close to this pin as possible (under 2 cm).
11 C/KI3 bidirectional LED segment C driver output, active high (max 30 mA per segment), which also serves as key-scan input KI3 with an internal pull-down; KI high input min is 1.8 V and low input max is 0.5 V.
12 D/KI4 bidirectional LED segment D driver output, active high (max 30 mA per segment), which also serves as key-scan input KI4 with an internal pull-down; KI high input min is 1.8 V and low input max is 0.5 V.
13 E/KI5 bidirectional LED segment E driver output, active high (max 30 mA per segment), which also serves as key-scan input KI5 with an internal pull-down; KI high input min is 1.8 V and low input max is 0.5 V.
14 F/KI6 bidirectional LED segment F driver output, active high (max 30 mA per segment), which also serves as key-scan input KI6 with an internal pull-down; KI high input min is 1.8 V and low input max is 0.5 V.
15 G/KI7 bidirectional LED segment G driver output, active high (max 30 mA per segment), which also serves as key-scan input KI7 with an internal pull-down; KI high input min is 1.8 V and low input max is 0.5 V.
16 DP/KP output LED decimal point segment output that also functions as the keyboard flag output KP, with an internal pull-up (typ. 2000 uA, range 500-5000 uA).
