R5F101JFAFA#X0 Datasheet/PDFR5F101JFAFA#X0 Application Field and Working Principle
R5F101JFAFA#X0 is a 32-bit microcontroller manufactured by Renesas (formerly known as Hitachi Microsystems). It is an 8-bit general-purpose microcontroller and is part of the R-series, which consists of several sequences of microcontrollers designed for specific functions. This chip is used in an array of applications such as automotive, industrial, home appliances, and office automation movements.
The R5F101JFAFA#X0 is equipped with the 32-bit Renesas R32C/T1 series CPU core and the Renesas M16C/T1 System Logical Technology Core, allowing it to perform operations at high speeds compared to other 8-bit microcontrollers. With 1K bytes of RAM and a 256K byte max ROM, the R5F101JFAFA#X0 can easily meet the needs of most embedded applications. The microcontroller includes a 10-bit A/D converter and a 10-bit D/A converter, as well as an 8-channel 8-bit PWM timer, making it suitable for low-resolution processing of analog signals. It also features features such as an External Bus Interface (EBI) and 9-channel Programmable Pulse Generator (PPG).
The microcontroller is available in compact packages such as UQFN and TSSOP, making it ideal for space-constrained applications. In addition, its operating temperature range, rated from 0°C to +70°C, makes it suitable for industrial and automotive applications.
The R5F101JFAFA#X0 has four operating modes, namely stop, sleep, idle and run. In the stop mode, the system is disabled and all oscillators are stopped. In the sleep mode, the oscillator is kept running at a minimum level, helping reduce power consumption. In the idle mode, the CPU core is halted, but the bus is kept active for accesses and peripherals. In the run mode, the microcontroller is active and fully functional.
The R5F101JFAFA#X0 includes a Reset and Interrupt Controller (RIC) module, which is used to enable and control the interrupt operations. The module supports 14 priority levels to enable interrupt processing. It also includes two dedicated interrupt signals to handle real-time applications.
The R5F101JFAFA#X0 includes a wide range of peripheral functions, including an 8-channel 8-bit general-purpose timer and an 8-channel 16-bit timer. It also features a Watchdog Timer (WDT) to help prevent system failure. With the R5F101JFAFA#X0, developers can create a range of embedded applications for automotive, industrial, home appliances, and office automation applications.
