Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VCCA | power_in | Power supply for port A, operating range 2.3V to 3.6V. |
| 2 | DIR | input | Direction control input; logic high selects A-to-B transfer, logic low selects B-to-A transfer. |
| 3 | A1 | bidirectional | Port A bidirectional data I/O channel 1, operating 0V to VCCA. |
| 4 | A2 | bidirectional | Port A bidirectional data I/O channel 2, operating 0V to VCCA. |
| 5 | A3 | bidirectional | Port A bidirectional data I/O channel 3, operating 0V to VCCA. |
| 6 | A4 | bidirectional | Port A bidirectional data I/O channel 4, operating 0V to VCCA. |
| 7 | A5 | bidirectional | Port A bidirectional data I/O channel 5, operating 0V to VCCA. |
| 8 | A6 | bidirectional | Port A bidirectional data I/O channel 6, operating 0V to VCCA. |
| 9 | A7 | bidirectional | Port A bidirectional data I/O channel 7, operating 0V to VCCA. |
| 10 | A8 | bidirectional | Port A bidirectional data I/O channel 8, operating 0V to VCCA. |
| 11 | GND | power_in | Ground reference. |
| 12 | GND | power_in | Ground reference. |
| 13 | GND | power_in | Ground reference. |
| 14 | B8 | bidirectional | Port B bidirectional data I/O channel 8, operating 0V to VCCB. |
| 15 | B7 | bidirectional | Port B bidirectional data I/O channel 7, operating 0V to VCCB. |
| 16 | B6 | bidirectional | Port B bidirectional data I/O channel 6, operating 0V to VCCB. |
| 17 | B5 | bidirectional | Port B bidirectional data I/O channel 5, operating 0V to VCCB. |
| 18 | B4 | bidirectional | Port B bidirectional data I/O channel 4, operating 0V to VCCB. |
| 19 | B3 | bidirectional | Port B bidirectional data I/O channel 3, operating 0V to VCCB. |
| 20 | B2 | bidirectional | Port B bidirectional data I/O channel 2, operating 0V to VCCB. |
| 21 | B1 | bidirectional | Port B bidirectional data I/O channel 1, operating 0V to VCCB. |
| 22 | OE | input | Output enable input, active low; logic high disables all outputs to high-impedance state. |
| 23 | NC | unconnected | No internal connection. |
| 24 | VCCB | power_in | Power supply for port B, operating range 3V to 5.5V. |
