EG301

EG Micro · Interface - Specialized · SOIC-8

EG301 from EG Micro, in a SOIC-8. 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 S0 input Key input pin 0 for the button matrix, with an internal pull-down of 40 to 80 kΩ (typ. 60 kΩ).
2 S1 input Key input pin 1 for the button matrix, with an internal pull-down of 40 to 80 kΩ (typ. 60 kΩ).
3 S2 input Key input pin 2, which also serves as the programming clock input (S2 or S3 acts as the serial clock in programming mode), with an internal pull-down of 40 to 80 kΩ.
4 S3 input Key input pin 3, which also serves as the programming clock input (S3 may be used in place of S2 as the serial clock), with an internal pull-down of 40 to 80 kΩ.
5 VSS power_in Ground pin; the datasheet requires VSS to be connected to ground.
6 PWM bidirectional Programming data input/output and rolling-code signal output pin, with an internal pull-down of 25 to 40 kΩ (typ. 30 kΩ).
7 /LED output Chip working LED indicator output pin that drives an external LED (active low by its /LED naming).
8 VDD power_in Power supply input pin; the operating supply range is 3.5 V to 13.0 V.
