The DA14531, also known as SmartBond TINY™, is an ultra-low power Bluetooth 5.1 SoC that supports up to three BLE connections. It integrates a 2.4 GHz transceiver and an ARM® Cortex-M0+ microcontroller with 48 kB of RAM and a One-Time Programmable (OTP) memory of 32 kB. The 2.4 GHz CMOS transceiver provides a programmable transmit output power from -19.5 dBm to +2.5 dBm with a receiver sensitivity of -94 dBm. The radio transceiver, the baseband processor, and the qualified Bluetooth low energy stack are fully compliant with the Bluetooth Low Energy 5.1 standard.
Available in packages as small as 2.0 x 1.7 mm, the DA14531 SoC only requires six external passive components, a single clock source and a power supply to make a complete Bluetooth low energy system. The device is suitable for disposables, wireless sensor nodes, beacons, proximity tags and trackers, smart HID devices (stylus, keyboards, mice, and trackpads), toys, and medical and industrial applications. This SoC is compliant with Bluetooth V5.1, ETSI EN 300 328 and EN 300 440 Class 2 (Europe), FCC CFR47 Part 15 (US) and ARIB STD-T66 (Japan) specifications.
