Silicon Labs has introduced new highly integrated 8-bit microcontrollers (MCUs) optimised for cost-sensitive motor control applications. The new C8051F85x/6x devices combine analog and communications peripherals, Flash sizes ranging from 2 KB to 8 KB, high performance and small-footprint packaging, making them ideal for brushless DC motor control applications used in remote controlled helicopters and cars, PC and electric fans, electric tools and small appliances.
The MCUs are also a good fit for other consumer and industrial applications such as power supplies, battery chargers, set-top boxes, projectors, lighting equipment and optical transceiver modules. Being AEC-Q100-qualified, they can also be used in automotive body electronics applications such as window lifts and power seats.
The chips feature a high-speed 8051 core and they support three independent high-resolution PWM channels with built-in over-current protection/fault detection capability specifically targeting motor control and power supply applications.
They 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. They 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.
Like all Silicon Labs 8-bit MCUs, the F85x/6x family features a patented crossbar architecture that enables developers to customise peripherals and pinout placement based on their application needs and layout constraints without worrying about pin conflicts.
Silicon Labs is also 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.
Two development kits are also offered for the F85x/6x MCU family: the C8051F850-B-DK development kit provides everything designers need to evaluate hardware and develop code including the C8051F850 target board, USB debug adaptor/programmer, power supply, cables, quick-start guide and complimentary downloadable software tools. The ToolStick850-B-SK starter kit enables designers to develop and debug application firmware directly on a target F85x/6x MCU using the Silicon Labs IDE.
