Cost-effective 8-Bit MCUs are optimized for motor control


The new C8051F85x/6x 8-bit MCUs from Silicon Labs combine best-in-class analog and communications peripherals, flash sizes ranging from 2 kB to 8 kB, high performance, small-footprint packaging, and cost-effective pricing. The new MCUs are targeted for a wide range of cost-sensitive motor control applications. The F85x/6x MCUs feature a high-speed 8051 core that is 50 percent faster than the closest in-class competitors. This high performance enables finer pulse-width modulation (PWM), enhanced motor control efficiency and the ability to execute more complex algorithms for a broad range of motor speeds.

The F85x/6x MCUs also support three independent high-resolution PWM channels with a built-in overcurrent protection/fault detection capability specifically targeting motor control and power supply applications.

The F85x/6x MCUs integrate advanced analog and digital peripherals into a small package. The MCUs include a 12-bit multi-channel analog-to-digital converter (ADC), two analog comparators with programmable hysteresis and response time, and a precise internal voltage reference. The MCUs also feature an integrated precision 24.5 MHz low-power oscillator and a low-frequency 80 kHz oscillator, eliminating the need for an external clock or crystal.

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. This combination of on-chip features enables developers to minimize external components, resulting in lower system cost compared to competing MCUs.

Complimentary Keil Development Tools
Silicon Labs is now offering complimentary Keil development tools for its entire portfolio of 8-bit MCUs and wireless MCUs including the new F85x/6x family. The PK51 Professional Developer's Kit for Silicon Labs’ 8-bit MCUs supports new devices with extended memory and instruction sets. Available without time or code size limits, the unrestricted Keil toolkit includes a wide range of build tools, such as assemblers, C compilers, code linker/locators and object converters, for use with Silicon Labs’ 8-bit MCU products and Microcontroller Studio. Silicon Labs’ 8-bit MCU customers can download the Keil tools at no charge .
