GN1622A from GN Semic, in a LQFP-44(10x10). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | CS | input | Chip Select Input (with internal pull-up resistor); when CS is high, data read/write is disabled and serial interface circuit is reset; when CS is low, data and commands are transferred. |
| 2 | RD | input | Read Clock (with internal pull-up resistor); data in RAM is output on the falling edge of RD clock. |
| 3 | WR | input | Write Clock (with internal pull-up resistor); data is stored on the rising edge of WR clock. |
| 4 | DATA | bidirectional | Serial Data (with internal pull-up resistor) for bidirectional data and command transfer. |
| 5 | VSS | power_in | Negative power supply; ground reference. |
| 6 | OSCI | input | External oscillator clock input. |
| 7 | VDD | power_in | Positive power supply voltage; operating range 2.7V to 5.2V. |
| 8 | VLCD | input | LCD working voltage input; must be lower than VDD. |
| 9 | IRQ | output | Interrupt request overflow output; open-drain output that outputs 2 kHz/4 kHz timebase or WDT overflow signal. |
| 10 | T1 | unconnected | Not connected; internal timing signal not available on this package variant. |
| 11 | T2 | unconnected | Not connected; internal timing signal not available on this package variant. |
| 12 | T3 | unconnected | Not connected; internal timing signal not available on this package variant. |
