Figure 1. DBB03 - Baseband ASIC for the Dolphin Chipset

The Wireless UART Dolphin chipset is a true Data-In/RF-out and RF-in/Data-out solution with all aspects of data

management and frequency hopping implemented in firmware residing on the DBB03. As illustrated in Figure 1,

the DBB03 baseband ASIC contains the complete firmware for Dolphin (PHYsical, MAC and the Data Link layer),

while the application layer protocol is handled by the external Host/System Microcontroller.
