IoT (IoT) field energy-saving microcontroller (MCU) solution leadership suppliers Silicon Labs (NASDAQ: SLAB) today announced the latest members of its EFM8 8-bit MCU product portfolio, design aim Demand for ultra-low power consumption, small size package, and capacitive touch in the IOT application.
The new EFM8SB1 SLEEPY BEE MCU is the smallest MCU in the industry, supporting 1.78mm × 1.66mm wafer-level chip size package (WLCSP), a quarter of the traditional 8-bit MCUQFN package size. These minimal MCUs are ideal for IOT and industrial applications such as touch, battery power supply and space, they usually require long battery life and efficient user-friendly interfaces, including wearable, remote control, Bluetooth Accessories, e-readers, and industrial automation, home automation, and office equipment.
EFM8SB1 SLEEPY BEE MCU is the most energy-saving 8-bit microcontroller of Silicon Labs, providing industry-leading sleep mode energy (only 50NA under memory content and only 50NA under the condition of power-down detection) and ultra-fast 2μs wake-up time. The kernel speed can be extended to 25MHz, and the flash capacity supports 2KB to 8KB. The MCU also integrates a first-class capacitive sensor controller, providing ultra-low power consumption touch wake-up capabilities (<1μA) and 12-channel reliable capacitive touch sensitive channels, thereby eliminating in numerous spatial sensitive products (such as wearable devices) The ON / OFF switch in the usual required.
In addition to providing advanced on-chip capacitive induction technology, Silicon Labs supports touch induction interface designs in the IOT product in the IoT product, in addition to providing advanced Capacitive Sense Library, which integrates excellent Capacitive Sense Library (Capacitive Substation), which is integrated in the Simplicity StudioTM development platform. Features and algorithms. SIMPLICITY STUDIO provides firmware designers to include firmware that includes mass production from scan buttons to noise filtering. By using the Simplicity Studio Capacitive Sense Profiler tool, you can visualize the noise level of real-time data and capacitive touch buttons, developers can easily customize the touch and non-touch threshold and noise filtering configuration, which greatly simplifies adds capacitive touch in IoT applications. Functional difficulty.
EFM8SB1 MCU provides a wealth of simulation and digital peripherals, including High Resolution Capacitor Digital Converter (CDC), 12-bit Module Converter (ADC), High Performance Timer, Enhanced SPI, I2C, and UART Serial Port. Developers can use these as well as other analog / mixed signal peripherals by Silicon Labs special CROSSBAR technology.
Silicon Labs Microcontroller Product Marketing Director Tom Pannell said: "EFM8SB1 Sleepy BEE series products integrate excellent energy efficiency, capacitive touch sensitivity, rich peripheral set, first-class development environment and the world's smallest MCU size, reflecting us Advocacy "Strict Perfect MCU" design concept. If you need a very small size, ultra-low-power capacitive touch induction MCU is used to design the required flash capacity below 8kb, then EFM8SB1 MCU is the best IoT design choose."
