GN1623L from GN Semic, in a LQFP-100(14x14). 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 | CS | input | Chip select with internal pull-up; low level enables the communication interface. |
| 2 | RD | input | Communication-interface read control input with internal pull-up; data is output on the falling edge. |
| 3 | WR | input | Communication-interface write control input with internal pull-up; input data is latched on the rising edge. |
| 4 | DATA | bidirectional | Communication-interface data input/output with internal pull-up. |
| 5 | VSS | power_in | Ground. |
| 6 | OSCI | input | Leave floating when using the internal clock; when using an external clock, the clock signal can be fed into OSCI. |
| 7 | OSCO | output | When an external crystal is used, a 32.768 kHz crystal is connected between OSCI and OSCO. |
| 8 | VDD | power_in | Positive supply pin. |
| 9 | VLCD | input | LCD operating voltage input, used to adjust the LCD drive voltage. |
| 10 | IRQ | output | Time-base or WDT overflow output using an NMOS open-drain driver. |
| 11 | BZ | output | Buzzer drive output at 2 kHz or 4 kHz, used together with BZ to drive a buzzer directly. |
