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). |
