The C8051F567-IM is embedded with an 8-bit USB microcontroller. As part of the Silicon Labs\' 8-bit MCU family, it is ideally suited for applications such as human computer interface (HCI), consumer, industrial, medical and automotive embedded designs. This microcontroller’s architecture is optimized for cost-sensitive, real-time applications.

Application field:

The capabilities of the C8051F567-IM make it ideal for a variety of applications. Its USB 2.0 full-speed controller provides a cost-effective means of interfacing to HCI or USB-based applications. It is suitable for consumer, industrial, medical, and automotive embedded designs due to its extended operating temperature ranging from +-40ºC to +85ºC.

Additionally, its Inter-Integrated Circuit (I2C) master/slave controller makes the C8051F567-IM a good choice for consumer, industrial and automotive applications that require wireless communication. In consumer applications, it can be used to control a wide range of consumer electronics, such as TVs, DVD players, washing machines, refrigerators, air conditioners, and security systems. Also, its I2C slave/master controller can be used for Industrial applications such as in sensors and actuators, machine control, and data logging and capture systems. And, automotive applications such as audio, navigation, heating, venting, and climate control (HVAC) systems, can all benefit from the C8051F567-IM.

Working principle:

The C8051F567-IM is powered by an 8-bit 8051-core processor with extra instructions and peripheral connectivity, allowing developers to tailor their system performance and cost. Its 8051 processor is based on 8 general purpose registers, each 8 bits wide. The processor executes instructions out of its on-chip flash memory, and has features such as timers, counters, UART, SPI and I2C interface controllers, a 10-bit ADC, Programmable Gain Amplifier (PGA), watchdog timer, and an equation solver.

The C8051F567-IM features an Enhanced Lock Bits (ELB) protection control to secure its on-chip resources from unauthorized access. It also provides an internal oscillator that can be programmed to any frequency from 1 MHz to 25 MHz. The oscillator also consumes very low current in active and idle mode, making it suitable for cost sensitive applications.

As for its USB Host/Device capabilities, the C8051F567-IM supports USB 2.0 Full-Speed and includes an integrated device and host controller. The on-chip Host/Device controller contains an 8-bit data port, separate from the central system 8051 8-bit data bus. This allows the device to perform both USB Host and USB Device activities, while running an 8051 application. The host/device controller provides a direct access to the USB port and allows developers to implement different USB operations without occupying any CPU cycles.

The C8051F567-IM also contains a number of communication peripherals, such as the SPI and I2C interface controllers. These peripherals provide a low cost and low-power solution for communication between multiple devices. The SPI interface controller operates in three different modes: Master mode, Slave mode, or a dual mode. It supports speeds of up to 12 Mbits/s, and has the ability to change the data rate on the fly.

In addition to the SPI Controller, the I2C Interface Controller provides two different operation modes, master and slave. The controller provides a maximum bus speed of up to 400 kHz and supports 7-bit or 10-bit addressing. It also contains an interrupt on-completion feature, allowing the device to remain idle until an I2C transaction is completed. Furthermore, the controller has the ability to perform multi-master transactions.

In summary, the C8051F567-IM is an 8-bit USB Microcontroller which is tailored for cost-sensitive, real-time applications in the fields of consumer, industrial, medical, and automotive embedded designs. It is packed with several advanced peripherals, including an 8-bit 8051-core processor, USB 2.0 full-speed, I2C master/slave controller, SPI controller, and an internal oscillator. This makes it optimal for applications such as HCI, wireless communication, machine control, and data logging and capture.
