8bit mcus offer 'best in class' analogue integration
1 min read
Optimised for cost sensitive motor control applications, the new C8051F85x/6x family from Silicon Labs is said to combine best in class analogue and communications peripherals.
The AEC-Q100-qualified 8bit mcus feature a high speed 8051 core that is 50% faster than the closest competitor. This, says the company, results in finer pulse width modulation (pwm), enhanced motor control efficiency and the ability to execute more complex algorithms for a range of motor speeds.
Also suitable for use in other consumer and industrial applications, the mcus support three independent high resolution pwm channels with a built in overcurrent protection/fault detection capability specifically targeting motor control and power supply applications.
Additional features include a 12bit multi channel a/d converter, two analogue comparators with programmable hysteresis and response time, a precise internal voltage reference, an integrated precision 24.5MHz low power oscillator and a low frequency 80kHz oscillator.
An on chip temperature sensor simplifies system calibration without having to add a discrete sensor. Multiple communications peripherals (I2C, SPI and UART) also give developers the flexibility to choose their peripherals based on application requirements.
"Silicon Labs' new F85x/6x mcus offer the industry's most cost effective, highly integrated and feature rich 8bit solution for analogue intensive embedded applications such as motor control," commented Diwakar Vishakhadatta, the company's vice president and general manager of 8bit mcu products.
