The DBB03 from Texas Instruments is a baseband ASIC for the company's 'Dolphin' reference design. The firmware for the Dolphin reference design resides in the ROM-based program memory of the DBB03, and thus can be readily interfaced with a TRF6903 single-chip RF transceiver to generate a frequency hopping wireless UART 'Dolphin' reference design chipset.
The baseband ASIC, in addition to being an RF baseband processor, is also responsible for communications with an external host/system microcontroller. In a typical end user application, the Dolphin chipset would be connected up to an external host/system microcontroller that will send configuration messages, RF transmission messages into the Dolphin chipset, or receive status, RF messages received from the Dolphin chipset.
Any low-cost host/system microcontroller can be interfaced to the Dolphin chipset as long as the Dolphin host interface protocol for communication is adhered to, says Texas Instruments. The company recommends its ultra-low power MSP430 series of microcontrollers to interface with Dolphin. The interface is a simple UART consisting of RX and TX data lines.
The wireless UART Dolphin chipset is a true data-in/RF-out and RF-in/data-out solution having all aspects of data management and frequency hopping implemented in firmware on the DBB03. The DBB03 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.
