C8051F997-C-GUR also known as the Freescale’s 8-bit microcontroller is a silicon-based device developed for implementing low cost and low power 8-bit microcontrollers into the embedded system. It is well recognized for their small size and easy set-up, and small amount of program memory. In addition, it is highly reliable and can withstand the most challenging environment.

The C8051F997-C-GUR has two peripheral functions embedding an 8051 Microcontroller, 8 kbyte Flash memory, 256 or 512 bytes of SRAM memory. It can uses 20 pin TQFP or 28 pin PQFP packages, with a 16MHz crystal as a clock source. Due to its small size and low power requirements, it can be integrated into many kinds of embedded systems.

The application field of the C8051F997-C-GUR includes telecommunications and data communication, industrial control system, consumer electronics, automotive components, and home entertainment products.

Let\'s examine the key features and concept regarding the working principle of a C8051F997-C-GUR microcontroller. The internal architecture is basically an 8051 architecture with a 16-bit data bus that feeds instructions and data to the microcontroller. The 8051 microcontroller has 8- bit instructions as well as its own memory, I/O ports, and A/D converter. The flash memory is programmable, writable and erasable memory chip and can be used to store programs, data and constants.

The instruction set of the 8-bit microcontroller consists of over twelve common machine instructions. The 8051 executes each instruction by decoding it, executing it with appropriate internal registers or outside peripherals, then sending the appropriate signal on the data bus back to the CPU. The overall processing of such instructions is known as CISC (Complex Instruction Set Computing).

The C8051F997-C-GUR microcontroller includes 8 kbyte Flash memory, 256 or 512 bytes of SRAM memory, 20 pin TQFP or 28 pin PQFP packages, with the 16 MHz crystal as clock source. All the internal registers, the I/O ports, the A/D converter and memory can be accessible using the serial port or the I2C. The Program memory, RAM and I/O ports can be interfaced using the parallel port, UART, SPI, and I2C.

In addition, the microcontroller has various features such as monitoring, temperature sensing, timer and analog comparator. Precise hardware management and hardware level customization enable hardware professionals to build their custom applications for a wide range of applications. The C8051F997-C-GUR also features robust features such as watchdog timer to prevent system hang-up and CRC checker, providing greater stability even when underlong-running or high-performance tasks.

The C8051F997-C-GUR is highly reliable and can withstand the most challenging environment. The integrated peripherals and system management enable the development of building custom microcontroller-based application with low cost, reliability, and ease of use.
