# RSL15 Hardware Reference

This group of topics provides a reference to the system hardware for application developers working with RSL15. This reference describes all of the components belonging to RSL15 , including:

| • | Bluetooth® and generic RF support

| • | Data processing and control components

| • | Security elements

| • | Clocking components and power supply

| • | Memory components

| • | Interfaces

| • | Peripherals

The data processing and control component information provided by this reference complements the Arm® Cortex®-M33 core description in The Definitive Guide to the Arm Cortex-M23 and Cortex-M33 Processors and other third-party documentation for the Arm Cortex-M33 processor.

The RSL15 Hardware Reference describes how each component of RSL15 can be used in the implementation of an application, and provides information about the configuration of the various system components. This group of topics is a part of the RSL15 Software Development Kit (RSL15 SDK).

This reference is primarily intended for engineers and other individuals who are responsible for developing and/or maintaining Bluetooth and other RF-based communication applications that make use of RSL15. People who are developing local interfaces between an external device and RSL15, as well as those interested in the details of the audio, power supply and clocking components, will find this group of topics particularly helpful, as it focuses on the configuration and use of system components.

This reference assumes that readers are familiar with C-level programming, RF application concepts, and Bluetooth Low Energy technology.
