Weltrend Semiconductor Kaohsiung Branch Rolls Out ROHM Sensor Total Solution
2016-08-05
Kaohsiung, Taiwan, June 20, 2016 – Weltrend Semiconductor (TAIEX: 2436) Kaohsiung Branch today announced the availability of its total solution for Internet of Things (IoT) that combines Weltrend’s WT51F1xx MCU and ROHM’s sensor plus its Bluetooth Low Energy (BLE) 4.1 module. | |
A typical IoT application would require the combination of a MCU, wireless connectivity, sensor, and low power design technology. Weltrend Semiconductor Kaohsiung Branch, in partnership with its solution provider, provides reference designs and development boards that equip with sensor(s) depending on users’ application requirement to help accelerating customers’ IoT product development. | |
A recent case is the adoption of ROHM BH1745NUC color sensor in electronic pen application. The color pen uses BH1745NUC to detect colors of objects in the physical world and transfer the color information via Bluetooth to drawing devices such as a tablet to allow users to conveniently and instantly use the colors captured. | |
The BH1745NUC is a 16bit I2C digital color sensor IC that detects RGB (Red, Green, Blue) components and converts them into digital values. High sensitivity, wide detection range (0.005 to 40k lx), and excellent IR cut characteristics make it easy to accurately obtain the color temperature and brightness of ambient light, making it ideal for backlight adjustment in TVs, tablets, PCs, and other LCD-equipped applications. | |
Features of BH1745NUC include: | |
● | Internal filter provides superior IR cut characteristics |
● | Wide detection range: 0.005 to 40k lx |
● | Supports low transmittance (dark) optical windows |
● | I2C bus I/F (f/s mode support) |
● | Power down function reduces power consumption |
● | 50/60Hz light noise rejection function |
● | 1.8V logic input I/F |
● | Interrupt function |
● | Selectable slave address (L: 0111000, H: 0111001) |
Key Specifications of BH1745NUC include: | |
● | VCC Voltage Range: 2.3V to 3.6V |
● | Maximum Sensitivity: 0.005Lx/step |
● | Current Consumption: 130μA (Typ) |
● | Standby Mode Current: 0.8μA (Typ) |
● | Operating Temperature Range: -40°C to +85°C |
