Product details
Overview
R5F104MJGFA#30 from Renesas is a 48-pin LFQFP-packaged RL78/G14 16-bit microcontroller with 192 KB flash, 8 KB data flash, 20 KB RAM, and industrial-grade temperature support (−40°C to +105°C). It integrates a 32 MHz RL78 CPU core delivering 44 DMIPS, ultra-low-power operation (66 μA/MHz active, 0.60 μA RTC+LVD), and peripherals including 12-channel 10-bit ADC, dual UART/LIN, I²C, SPI, RTC, and watchdog timer - deployed in motor control and industrial sensor nodes.
For engineers reviewing the R5F104MJGFA#30 datasheet, R5F104MJGFA#30 pinout, R5F104MJGFA#30 application, or R5F104MJGFA#30 equivalent, key selection criteria include its G-grade extended-temperature rating, 48-pin 0.5 mm pitch LFQFP package, 192 KB code flash with self-programming and security lock, and integrated event-link controller (ELC) for deterministic peripheral triggering without CPU intervention.
Technical Context
The R5F104MJGFA#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs @ 32 MHz to 30.5 µs @ 32.768 kHz). It supports multiply/divide/accumulate instructions and 1 MB address space.
Its power management includes HALT, STOP, and SNOOZE modes, on-chip POR and 14-level LVD, and a high-accuracy ±1.0% on-chip oscillator (1–64 MHz). Peripheral integration features ELC (19–26 event sources), DTC for interrupt-driven transfers, and background operation for data flash rewriting.

Yes, the R5F104MJGFA#30 supports background operation (BGO) for data flash rewriting. During BGO, the CPU can execute instructions from program memory while the data flash is being rewritten, enabling seamless firmware parameter updates or data logging without halting real-time tasks - a feature confirmed in Section 1.1 "Features" of the R01DS0053EJ0370 datasheet.
What is the industrial temperature grade supported by the R5F104MJGFA#30, and how is it encoded in the part number?
The R5F104MJGFA#30 is rated for −40°C to +105°C operation, indicated by the 'G' in the fourth character position of the part number (R5F104MJGFA#30). This G-grade qualification meets industrial application requirements and is explicitly defined in Table 1-1 of the RL78/G14 datasheet as "Industrial applications" with extended ambient temperature range.
How many analog input channels does the 10-bit ADC in the R5F104MJGFA#30 support, and what reference options are available?
The R5F104MJGFA#30 integrates a 10-bit A/D converter with up to 20 analog input channels. It supports both external reference voltage and an internal 1.45 V reference, as documented in Section 1.1 "Features" and confirmed in the "A/D Converter" subsection of the R01DS0053EJ0370 datasheet Rev. 3.70.
Is the R5F104MJGFA#30 pin-compatible with other RL78/G14 variants in the same 48-pin LFQFP package?
Yes, all RL78/G14 devices in the 48-pin LFQFP package - including R5F104MJGFA#30, R5F104MLGFA#30, and R5F104MGAFB#30 - share identical pinouts and electrical characteristics per the RL78/G14 family datasheet. Pin compatibility is guaranteed within the same package type (LFQFP, 48-pin), enabling memory-scaling upgrades without PCB changes.
