Description
The DA14533 is an ultra-low power, AEC-Q100 Grade 2 qualified System-on-Chip (SoC) that integrates a 2.4GHz transceiver and an Arm® Cortex®-M0+ MCU with 64kB of RAM and 12kB of one-time programmable (OTP) memory. This SoC can function as a standalone application processor or as a data pump in hosted systems. Ultra-low power can be achieved using the integrated low IQ buck-boost DC/DC converter, which remains active during sleep in Buck mode.
The radio transceiver, the baseband processor, and the qualified Bluetooth® Low Energy (LE) stack are qualified against Bluetooth Core 5.3.
