The CYBLE-0130XX-00 includes support for wireless charging in hardware, software, and firmware. It supports the protocol for 
implementing wireless charging solutions based on the specifications written by the Alliance for Wireless Power (A4WP).

The A4WP protocol is embedded in the CYBLE-0130XX-00. Hardware and firmware elements required for wireless charging are either 
implemented in the CYBLE-0130XX-00 or can be obtained through a Cypress technical support representative.

An end-to-end charging solution comprises of the following:

n

Power Transmitting Unit (PTU): The PTU transfers the power to the receiving unit. The receiving unit is any device (phone, wearable, 

or other embedded device) that needs to be charged. The PTU is typically plugged into a power source such as a wall outlet. The 

CYBLE-0130XX-00 includes the peripherals needed to implement and drive a reference charging circuit and otherwise requires 

only a few external components. PTU reference designs based on the CYBLE-0130XX-00, including bills of material (BOMs), are 

available through Cypress technical support. Depending on charging power requirements, a Power Management Unit (PMU) such 

as the BCM8935X may be included in the design. However, most PTUs requiring < 5W will not need a PMU. The references designs 

leverage ADCs, PWMs, and other internal peripherals to help drive the charging circuitry for energy transfer as well as provide 

feedback for charging control. The application and algorithm that drive the reference designs are available on request.

n

Power Receive Unit (PRU): The PRU receives energy from the PTU to charge the local device, and is typically embedded in the 

local device. Like the PTU, a separate PMU may or may not be needed depending on power requirements. PRU reference designs 

based on the BCM20736, both with and without a PMU, are also available through Broadcom technical support.

CYBLE-0130XX-00 provides elaborate mechanisms for implementing security and authentication schemes using:

n

RSA (Public Key Cryptography)

n

X.509 (excluding parsing)

n

Hash functions: MD5, SHA-1, SHA-224, SHA-256, SHA-384, SHA-512 

n

Message authentication code: HMAC MD5, HMAC SHA-1

Details on how to use this functionality via SDK are available in application notes on this topic.

CYBLE-0130XX-00 provides support for "ease of pairing" and "secure key exchange" use cases using passive tags. Active tags can 
be used with the chip for OOB pairing. In a typical use case, the BCM20203 (NFC tag) can be used to provide "tap to pair" functionality 
for easy pairing.

Note: Details on how to use this functionality via SDK are available in application notes on this topic.

CYBLE-0130XX-00 supports using the BLE link for audio streaming. This functionality can be used for audio applications in toys, 
wearable, and HID devices, as well as in hearing aids.
