Le ATM3330E-3DCAQN-SR est un SoC BLE 5.3 Atmosic (serie ATM33e) avec processeur Cortex M33F 64 MHz, ARM TrustZone, detection directionnelle AoA/AoD et recuperation d'energie integree (RF, photovoltaique, thermoelectrique, cinetique), disponible en boitier QFN 7×7 mm (56 broches, Jusqu'a 31 GPIO). Conditionnement : Bobine standard (Standard Reel). Il partage la meme architecture et les memes performances BLE que les autres variantes de la famille ATM3330E, avec pour seule difference le boitier et le conditionnement.
Key Features
- BLE 5.3 compliant: data rates of 2 Mbps, 1 Mbps, 500 kbps, and 125 kbps (CODED PHY for long range).
- ARM Cortex-M33F processor - 64 MHz (FPU + DSP): open core for developing applications directly on the SoC without a host microcontroller.
- Integrated Sensor Hub (operations without waking the CPU): execution of peripheral tasks (memory access, beacon transmission) without waking the CPU—extending battery life.
- RF Wake Up features: waking the SoC upon receipt of an RF signal without significant standby power consumption.
- Integrated energy harvesting: Yes - On-chip RF + photovoltaic / thermoelectric / kinetic (external ports) - Battery-free operation possible depending on the environment.
- Hardware security: ARM TrustZone, Secure Boot, AES-128/256, SHA-2, TRNG.
- AoA/AoD Directional Detection: Directional indoor geolocation without additional infrastructure.
