R5F104GEAFB#30 is a one-time programmable, low-cost 8-bit microcontroller developed by Renesas Electronics Corporation. It is intended for general purpose applications and is based on the RISC-V instruction set architecture. It features a 32-bit Reduced Instruction Set Computer (RISC) CPU core that includes 16 special functions for fast processing, as well as an 18-bit address bus. It also has an 8-bit data bus, temporal flexibility, and a 12-bit program memory.

R5F104GEAFB#30 is suitable for a wide range of applications such as automotive, home appliances, industrial and consumer applications, medical and industrial automation, audio and video, smart sensors, and low-power IoT (Internet of Things) applications. Specifically, it provides a specialized instruction set to improve the power efficiency of the target microcontroller, and enhanced timers, serial communication interfaces, and PWM (pulse width modulation) peripherals.

R5F104GEAFB#30 operates on a single 3.3V power supply and is available in various packages ranging from 8-pin to 128-pin. It also offers allows up to 16KB flash memory and 4KB RAM, as well EEPROM and I2C capability depending on R5F104GEAFB#30 model. Furthermore, it provides four different clock modes, eight 16-bit timer channels, two 8-bit timer channels, fast interrupt functions, and up to four analogue comparators.

The working principle of the R5F104GEAFB#30 is based on its RISC architecture. It incorporates two pipelines for fast execution of instructions. The first pipeline handles the initial instruction fetch, executing the instruction and calculating the result, while the second pipeline handles the address calculation and loads or stores the data. This dual pipeline design provides high performance for critical applications. The pipeline also supports branch prediction, branch delayed execution, branch target instruction register and branch history predictability.

In addition, the CPU core of R5F104GEAFB#30 also allows dynamic power-down mode in which various reset codes are used to bring the microcontroller into a lower power state. This feature helps to conserve battery power and reduce the power consumption of the chip while maintaining the highest level of performance. The dynamic power-down mode is also used to switch the operating frequency according to the current application demands, while maintaining a low power consumption.

R5F104GEAFB#30 has an 8x 8bit bus, 16KB flash memory and 4KB RAM, as well as EEPROM support. It has 18-bit arithmetic/logic unit (ALU), 13-bit timer, 8 8-bit I/O ports and can provide data communication protocols such as CAN, LIN, and SPI, as well as USB and UART. It supports up to four 16-bit timer channels for advanced control applications. It also includes a Fast Interrupt Controller (FIC) for fast interrupt responses and flexible input/output multiplexing.

In summary, R5F104GEAFB#30 is a low-cost, one-time programmable 8-bit microcontroller developed by Renesas Electronics Corporation. It is designed to meet the needs of embedded applications and provides a high level of performance, temporal flexibility, enhanced timers, serial communication interfaces, and PWM peripherals.
