Bluetooth Smart SoC 4.4
The DA14580 integrated circuit has a fully integrated radio transceiver and baseband processor for
Bluetooth
®
Smart. It can be used as an application processor as well as a data pump in systems with
an external processor.
The DA14580 contains an embedded One-Time-Programmable (OTP) memory for storing Bluetooth
profiles as well as custom application code. The qualified Bluetooth Smart protocol stack which is
stored in a dedicated ROM, and the customer application software which is stored in system RAM,
both run on the embedded ARM
®
Cortex
®
-M0 processor. Low leakage Retention RAM is used to
store sensitive data and connection information while in Deep Sleep mode.
The radio transceiver implements the RF part of the Bluetooth Smart protocol. Together with the
Bluetooth 4.0 PHY layer, it provides a 93 dB RF link budget for reliable wireless communication. All
RF blocks are supplied by on-chip low drop out regulators (LDOs). The RF port is single ended 50 Ω,
so no external balun is required.
The DA14580 has dedicated hardware for the Link Layer implementation of Bluetooth Smart and
interface controllers for enhanced connectivity capabilities.
The DA14580 is equipped with a DC/DC converter that can be configured either for buck or boost
mode operation. On this module both configurations are available. The default configuration is a buck
mode DC/DC converter. Also, the FCC/ETSI certification is valid only for the buck configuration.
