Use native high-speed USB and more memory to expand peripheral and receiver functionality
Native high-speed USB, approximately 2MB NVM, and 512KB RAM provide resources for wired peripherals, USB receivers, macros, lighting, firmware updates, and feature integration. Interface configuration depends on the specific variant and package.
Applications
Plan wired peripheral and USB receiver data paths around native high-speed USB, approximately 2MB NVM, and 512KB RAM, with space for macros, lighting, updates, and richer firmware.

Plan native USB, memory allocation, input processing, and driver functions together, confirming interfaces and GPIO resources for the chosen A/B variant and package.
Up to 8K polling configuration in both wired and 2.4G modes.
Unified wired, 2.4G, and Bluetooth connection, switching, and pairing.
Plan wired data paths, USB receivers, and richer firmware functionality around native high-speed USB, approximately 2MB NVM, and 512KB RAM.
Active, idle, sleep, and wake strategies planned for the usage scenario.
Configuration, firmware updates, receiver tools, and branded software.
RF, performance, power, reliability, and production-test validation.
Customization Scope
Define the chip variant, USB interface, and firmware resource budget, then integrate input, lighting, drivers, and updates before validating device performance and power.
PCBA planned around enclosure, antenna, power, USB, sensor, and target BOM.
Customer-selected sensor integration with mouse sampling or keyboard matrix tuning.
Project-specific polling, connectivity, controls, lighting, power, and updates.
Complete-device performance validation, test tools, pilot run, and production support.
Selection Guidance
Evaluate Nordic nRF54LM20 when wired peripherals or USB receivers need native high-speed USB, or when macros, lighting, updates, and richer firmware require more memory. Both it and nRF54L15 use a 128MHz CPU; selection centers on interfaces and memory, with implementation confirmed for the chosen variant and package.
Prepare the A/B variant and package, USB data path, firmware memory budget, macro and lighting requirements, update strategy, and receiver functions.
Parameter Notes
Native high-speed USB, approximately 2MB NVM, and 512KB RAM are chip resources. Interface and GPIO configuration depend on the actual A/B variant and package. Dual 8K and mouse operating current below 10mA still require validation with the sensor, board, firmware, and test conditions.
