Podzespoły  BlueNRG-1 - Bluetooth Low Energy SoC 

 

Firma STMicroelectronics poinformowała o wprowadzeniu do oferty układu SoC pełniącego rolę bezprzewodowego interfejsu BLE. Zawiera on interfejs radiowy mający możliwość szybkiego przełączania pomiędzy trybem energooszczędnym i aktywnym, co jest dopasowane do wymagań nowoczesnych aplikacji angażujących do komunikacji interfejs Bluetooth, przenośnych, zasilanych z baterii lub akumulatorów.

Układ wyposażono w rdzeń Cortex-M0, 160 kB pamięci Flash i 24 kB pamięci RAM z podtrzymaniem zawartości (dwa banki po 12 kB). Do komunikacji z otoczeniem służą interfejsy szeregowe SPI, UART oraz I²C. Umożliwia to współpracę z szeroką gamą układów peryferyjnych, w tym z sensorami oraz dodatkowymi układami pamięci.

Prąd zasilający w trybie wyłączenia wynosi około 1 µA, Moc wyjściowa nadajnika jest równa +8 dBm, co umożliwia pewną komunikację z urządzeniami Bluetooth. Układ SoC jest zgodny z wymaganiami wielu norm, w tym ETSI EN 300 328, EN 300 440, FCC CFR47 Part 15 oraz ARIB STD-T66.

Do opracowywania aplikacji jest dostępna płytka ewaluacyjna STEVAL-IDB007V1, która oprócz samego SoC typu BlueNRG-1 zawiera również akcelerometr, żyroskop, czujnik ciśnienia i temperatury, złącze interfejsu debugera.
