Working Principle

The C8051F304-GS consists of a core and peripheral blocks with each block having its own memory and registers. The core is responsible for controlling the other blocks and executing the user’s program. It is organized as an 8-bit RISC processor with a 16-bit address bus and an 8-bit instruction word with integrated RAM and ROM. The peripheral blocks connected to the core include three counter/timers, one analog-to-digital converter, four universal asynchronous receiver transmitters, two serial peripheral interfaces, and two serial data and two serial clock interfaces.

The C8051F304-GS is a Harvard architecture device with separate instruction and data memory. The core uses program memory to store the user’s program and data memory to store variables. The memory and peripheral blocks are connected to the core through multiplexed buses and are actively managed by the core. This helps the core control the peripheral modules to meet the requirements of the user’s application.

The C8051F304-GS can be configured to run in either single-cycle or multi-cycle mode. In single-cycle mode, the core executes instructions as they are received from memory. In multi-cycle mode, the core can execute multiple instructions in the same clock cycle and thus improves the execution speed of the user’s program. The core can also be configured to run in in-circuit debugging (ICD) mode, which helps developers to easily debug and optimize their program.

The C8051F304-GS has an on-chip oscillator and an on-chip power-on reset (POR) circuit. The POR circuit monitors the power supply of the device and detects any power interruptions in order to reset the device automatically. It also has an on-chip watchdog timer (WDT) to detect software errors or other conditions which can cause the device to hang. The WDT can be configured to reset the device to its initial state if it detects any abnormal operation.

The C8051F304-GS has an on-chip analog-to-digital (ADC) converter. It is used to convert analog signals such as temperature, voltage, and current into digital values which can then be processed by the microcontroller. The ADC has four 10-bit channels which can be used to measure up to four signals at the same time. The ADC can operate at up to 1MHz and has a low power consumption of 48mA.

The C8051F304-GS has four universal asynchronous receiver transmitters (UARTs). These UARTs can be used to communicate with external peripherals such as sensors and keyboards. The UARTs can be configured to operate in 8-bit, 9-bit, or 16-bit data modes and can support up to five different baud rates. The UARTs are also capable of data synchronization, data rate control, and synchronous communication.

The C8051F304-GS has two serial peripheral interfaces (SPI) and two I2C interfaces. These interfaces are used to communicate with external devices such as memories, flash memories, LCDs, and sensors. The SPI can be configured to operate in either master or slave mode, the I2C interfaces can be configured to operate in either master or slave mode, and both support up to five different baud rates.

The C8051F304-GS has an external memory interface (EMI) which can be used to connect external devices such as CAN, USB, and external memories. The EMI supports a variety of external devices with various baud rates, data widths, and transfer protocols.
