Shenzhen Mingjiada Electronic Components Distributor offers the R5F104JGAFA low-power 16-bit MCU in stock: a high-performance general-purpose microcontroller designed specifically for motor control, industrial, and metering applications.
In modern embedded system design, the real-time requirements of motor control, the reliability challenges of industrial equipment, and the low-power demands of metering instruments often present engineers with difficult trade-offs during component selection. The R5F104JGAFA microcontroller from Renesas Electronics’ RL78/G14 series was designed precisely for this purpose—this 16-bit general-purpose MCU strikes an excellent balance between low power consumption, computational performance, and peripheral integration, making it the ideal core for applications such as industrial control, smart home appliances, and battery-powered devices.
Product Overview: A Truly Low-Power Platform with 44 DMIPS of High Computing Power
The R5F104JGAFA is equipped with Renesas’ proprietary RL78 CPU core (16-bit CISC architecture, 3-stage pipeline), operating at a maximum frequency of 32 MHz and delivering 44 DMIPS of processing performance. As a mainstream model in the RL78/G14 series, it consumes as little as 66 μA/MHz when operating at full speed, only 0.60 μA in standby mode (with RTC and LVD enabled), and as low as 0.24 μA for RAM data retention in STOP mode. These “true low-power” characteristics give it a significant advantage in portable devices and power-sensitive applications.

Extensive Integrated Peripherals: Designed Specifically for Motor Control and Industrial Applications
The R5F104JGAFA incorporates high-performance timers required for three-phase motor control, supporting three-phase complementary PWM output (up to 13 PWM channels), capable of directly driving BLDC motors or permanent magnet synchronous motors. Its analog peripherals include:
12-channel 10-bit A/D converter (supports internal reference voltage of 1.45V and temperature sensor)
2-channel 8-bit D/A converter
Multiple communication interfaces: CSI (SPI), I²C, UART (supports LIN-bus)
In addition, the chip integrates an Event Link Controller (ELC), Data Transfer Controller (DTC), watchdog timer, and real-time clock (RTC), which significantly reduce CPU interrupts and enhance the system’s real-time response capabilities.
Industrial-Grade Safety Features: Compliant with IEC/UL 60730 Standards
To address the functional safety requirements of home appliances and industrial equipment, the R5F104JGAFA incorporates safety mechanisms such as Flash CRC calculation, RAM parity checking, SFR write protection, clock stop/frequency anomaly detection, and I/O port readback. These features meet the IEC/UL 60730 Class B safety standard, providing hardware-level safety assurance for devices such as washing machines, air conditioners, and electric drills.
