Silicon Labs (also known as "Core Technology") announced the launch of two series of automotive-level EFM8 microcontrollers (MCU) products, designed to meet extensive car touch interface and body electronic motor control applications. After AEC-Q100 authentication, ultra-low power consumption new EFM8SB1 SLEEPY BEE series provides advanced chip-on-chip capacitive touch technology, you can use touch control to easily replace the physical button. The EFM8BB1 / BB2 BUSY BEE series features high-performance simulation and digital peripherals, so that these devices can be used as a general choice to control electric rearview mirrors, headlights, and seats.
All EFM8 MCUs released are based on the 8051 kernel and implements a combination of different functions and performance, including high-speed pipeline 8051 kernel, ultra low power consumption, accuracy simulation, enhanced communication peripherals, on-chip oscillator, small size package And a patented Crossbar architecture that provides flexible digital and analog external tubes to simplify printed circuit board (PCB) design and I / O pins.
Be
The EFM8SB Sleepy Bee MCU Series is the most energy-saving 8-bit MCU of Silicon Labs, providing unparalleled touch performance, ultra-low sleep mode energy consumption (only 50NA under memory content and power-down detection enable conditions) and fast 2μs wake-up time . The automotive grade EFM8SB1 device supports the ambient temperature range of -40 ° C ~ + 85 ° C, the core speed is as high as 25 MHz, and the flash capacity is as high as 8KB. This series of MCUs integrate 12-bit model converters (ADCs), high performance timers, temperature sensors, and enhanced SPI, I2C, and UART serial ports. Sliced High Resolution Capacitor Digital Converter (CDC) provides ultra-low power consumable touch wake-up capabilities (<1? A) and 12 reliable capacitive touch sensing channels, which can replace the physical buttons in many applications. The MCU is ideal for touch-based control devices such as top lights and head buttons. Capacitive touch control provides a more durable and moisture-proof user interface, and more fashionable.
Silicon Labs uses the integrated Capacitive Sense Library (Capacitive Substation "in the SimplicityStudio® Development Tool Suite to support touch induction interface design, providing all logical algorithms needed to add capacitive push keys in automotive applications. SIMPLICITYSTUDIO provides designers with firmware that can be used in mass production, including from scan buttons to noise filters. By using the CapAcitive Sense Profiler tool, you can easily customize the noise level of real-time data and capacitance touch buttons, developers can easily customize touch and non-touch thresholds and noise filtering configurations, greatly simplifying to add capacitive touch functions in the vehicle user interface. Difficulty.
EFM8BB1 / BB2 Busy Bee MCU Series provides a good balance in high performance, energy efficiency and prices for cost-sensitive applications. In addition to the internal nuclear rate of up to 50MHz, 2-64KB flash memory, the series MCU can also provide a series of high-performance peripherals in a package of 3mm x 3mm, including high-resolution 12-bit ADC, high-speed 12-digit model Converter (DAC), low power comparator, built-in reference power supply, enhanced communication peripherals and internal oscillators. This extraordinary single-chip integration design eliminates the demand for discrete analog metals while shrinking system costs and board occupancy spaces.
Since the width temperature range of -40 ° C ~ + 125 ° C is supported, the EFM8BB1 / BB2 devices are suitable for those who must meet stringent car qualification, and can work within the wide temperature range while providing high performance applications at all temperatures. EFM8BB1 devices provide optimal cost performance for cost-sensitive design, while EFM8BB2 products provide enhanced simulation and digital peripheral performance. For analog intensive automotive body control applications, such as seat adjustment, fan control, window lift and fuel tank sensor, EFM8BB1 / BB2 MCU is a good choice.
Configurator and Energy PROFILERs in SimPlicity Studio help developers accelerate design processes and optimize energy efficiency. EFM8 customers can download Simplicity Studio tools from the official website of Silicon Labs www.silabs.com/simumity-studio.
