Product details
Overview
R5F104MGAFB#30 from Renesas is a 80-pin LFQFP, 0.5 mm pitch, industrial-grade (G) RL78/G14 16-bit MCU with 96 KB flash, 12 KB RAM, and 8 KB data flash, operating from 1.6–5.5 V at -40 to +105°C. It integrates RTC, 10-bit ADC (19 channels), UART/SPI/I²C interfaces, and ultra-low-power modes (0.60 μA in STOP with RTC+LVD) for battery-powered industrial control and sensor nodes.
For engineers reviewing the R5F104MGAFB#30 datasheet, R5F104MGAFB#30 pinout, R5F104MGAFB#30 application, or R5F104MGAFB#30 equivalent, key selection criteria include its 80-pin LFQFP-0.5 mm package, G-grade temperature rating, integrated 8 KB data flash with 1M rewrite cycles, and support for background operation during flash reprogramming.
Technical Context
The R5F104MGAFB#30 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). It features an Event Link Controller (ELC) enabling direct peripheral-to-peripheral event triggering without CPU intervention, and a Data Transfer Controller (DTC) supporting chain transfers across multiple memory regions.
Its power architecture includes HALT, STOP, and SNOOZE modes, with dedicated low-speed on-chip oscillator for watchdog and RTC operation. The high-accuracy (±1.0%) 64–1 MHz on-chip oscillator eliminates external crystal requirements for many timing-critical applications while maintaining system responsiveness.

FAQ
What is the maximum operating frequency of the R5F104MGAFB#30?
The R5F104MGAFB#30 supports up to 32 MHz operation using the high-speed on-chip oscillator. Its minimum instruction execution time is 0.03125 µs at this frequency. The device also supports ultra-low-speed operation down to 32.768 kHz for RTC and low-power wake-up scenarios, with corresponding 30.5 µs instruction time.
Does the R5F104MGAFB#30 include hardware debugging support?
Yes, the R5F104MGAFB#30 includes full on-chip debug functionality compatible with Renesas E1 and E20 emulators. Pins P50 and P51 provide TOOLRxD/TOOLTxD signals, and the device supports flash programming, breakpoint setting, and real-time variable monitoring without requiring external debug hardware beyond the standard JTAG/SWD interface.
How many serial communication interfaces does the R5F104MGAFB#30 support?
The R5F104MGAFB#30 supports up to 10 serial channels: 3–4 UART/LIN interfaces, 3–8 CSI (SPI-compatible) channels, and 4–10 I²C/simplified I²C channels. Specific counts depend on pin multiplexing and configuration; the 80-pin package enables concurrent use of multiple protocols-for example, UART for host comms, CSI for display, and I²C for sensor hub.
What is the purpose of the REGC pin on the R5F104MGAFB#30?
The REGC pin on the R5F104MGAFB#30 connects to an external 0.47–1 µF capacitor tied to VSS, stabilizing the internal voltage regulator that powers the analog and low-power domains. This capacitor is mandatory for reliable operation-omission causes erratic ADC readings, RTC drift, or failure to enter STOP mode correctly.
Can the R5F104MGAFB#30 perform flash rewrites while executing application code?
Yes, the R5F104MGAFB#30 supports background operation (BGO) for data flash writes. Application code continues executing from program memory during data flash erase/write sequences, enabling seamless firmware parameter updates, data logging, or calibration storage without interrupting real-time tasks like motor control or sensor sampling.
