Pin assignments
The pin assignment figures and tables describe the pinouts for the product variants of the device.
The nRF54LM20A and nRF54LM20B device provides flexibility regarding GPIO pin routing and configuration. Some pins have limitations or recommendations on how the pin should be configured or what it should be used for.
As a general rule, peripherals must use GPIO pins in their own domain, and can be used for all peripheral functions when selected in the peripheral's PSEL register. Serial peripherals must use pins from the same port. Note the dedicated clock pin requirements. The dedicated clock pin requirements are described in Clock pins. Some device functions must use specific pins, as listed in Pin assignments.
The block diagram shows which peripheral and port belong together, see Block diagram.
The different GPIO ports have different properties. For details, see GPIO — General purpose input/output.
Dedicated pins
The device has some pins dedicated for specific purposes. GPIO pin routing and configuration is flexible. Some pins have limitations or recommendations for configuration and use.
| Peripheral | Description |
|---|---|
| TRACE | Has dedicated pins that must be configured using extra high drive E0/E1 configuration in the DRIVE0/1 fields of the PIN_CNF GPIO register. |
| GRTC | Has dedicated pins for clock and PWM output. |
| TAMPC | Has dedicated pins for active shield input and output. |
| FLPR | Uses dedicated pins on P2 for emulated peripherals such as QSPI. |
| RADIO | Uses dedicated pins on P1 for antenna switch control (DFEGPIO for direction finding). |
| NFC | Uses dedicated pins as listed in the pin assignments table for the selected device. These pins are configured as NFC antenna pins from reset. To use the pins for Digital I/O, NFC function must be disabled in the NFCT — Near field communication tag peripheral. |
Clock pins
The device has dedicated clock pins.
Some peripherals have clock signals. Dedicated clock pins have been optimized to ensure correct timing relationship between clock and data signals for these peripherals. See the following table for which peripheral signals must use clock pins. The pin assignment table identifies clock pins.
Clock pins can also be used as regular I/O data pins.
The peripheral data signal must be configured to use pins close to the clock pin. This ensures that the internal paths from the peripheral to the pin have the same delay, so that the data and clock signals reach the pins at the same time.
For high-speed signals, the printed circuit board (PCB) layout must use short PCB traces of identical length. This makes sure any delays are kept to a minimum, with close to identical delay on the clock and data path.
