The device should not be operated beyond the manufacturer’s specified electrical, thermal, or mechanical limits. ## Application Suitability The device is suitable for automotive Ethernet nodes, electronic control units, telematics modules, infotainment systems, sensor interfaces, industrial controllers, embedded gateways, connected equipment, and compact network-enabled hardware requiring 100BASE-T1 Ethernet PHY functionality. ## Hashtags #commonpartslibrary #integratedcircuit #ethernetphy #microchip #microchiptechnology #lan8770 #lan8770mipra #singlepairethernet #100baset1 #automotiveethernet #ethernettransceiver #phytransceiver #embeddednetworking #mii #rmii #vqfnpackage #smdcomponent #surfacemount #automotiveelectronics #industrialethernet #telematics #infotainment #embeddedhardware #pcbdesign #hardwaredesign #electronicscomponents #electronicparts #componentlibrary #engineeringparts #electronicsengineering

The ams OSRAM TCS3448 is a highly versatile, multi-purpose spectral light sensor designed to sense the spectral components of ambient light in the visible range. This 14-channel sensor is optimized for applications requiring precise color sensing and ambient light classification, making it ideal for enhancing camera performance through improved color temperature (CCT), automatic white balance (AWB), and exposure time adjustments. The TCS3448 features individual channels covering approximately 380 nm to 1000 nm, including 11 channels centered in the visible spectrum, one near-infrared (NIR) channel, and a clear channel. Additionally, it integrates a flicker detection channel that can automatically flag ambient light flicker at 50/60 Hz and buffer data for calculating other flicker frequencies. The sensor's high-precision optical interference filters are directly deposited on photodiodes embedded in CMOS silicon, ensuring accurate spectral data. With a built-in aperture, programmable digital GPIO, and LED driver, the TCS3448 offers robust control and synchronization capabilities. The device is available in an ultra-low profile package, making it suitable for a wide range of applications, from industrial automation to mobile and wearable devices. Features: 14-channel spectral sensing Visible range coverage (380 nm to 1000 nm) 11 visible spectrum channels Near-infrared (NIR) channel Clear channel Flicker detection up to 1 kHz Integrated aperture for increased accuracy High-precision optical interference filters Programmable digital GPIO LED driver for light source control Serial I²C interface (1.2 V/1.8 V) Ultra-low profile package (3.1 mm x 2 mm x 1 mm) Field of view (FOV) ±40° 0.18 µ process technology Compatible with AS7343 software #CommonPartsLibrary #IntegratedCircuit #Sensor #Transducers #Optical-Sensor #Ambient-Light #IR #UV-Sensor
