Product details
Overview
R5F104JGGFA#30 from Renesas is a 52-pin LFQFP-packaged RL78/G14 16-bit microcontroller with 96 KB flash, 12 KB RAM, and 8 KB data flash, operating from 1.6–5.5 V at -40 to +105°C (industrial G-grade). It delivers 44 DMIPS at 32 MHz, features ultra-low-power HALT/STOP/SNOOZE modes (66 μA/MHz active, 0.60 μA RTC+LVD), and integrates 10-bit ADC (16 channels), UART/LIN, I²C, SPI, RTC, and on-chip oscillators for embedded control in industrial sensor nodes and motor drives.
For engineers reviewing the R5F104JGGFA#30 datasheet, R5F104JGGFA#30 pinout, R5F104JGGFA#30 application, or R5F104JGGFA#30 equivalent, this page provides verified technical context, package mapping, real-world use cases, and validated alternative options - all grounded in Renesas' official RL78/G14 documentation (R01DS0053EJ0370 Rev. 3.70).
Technical Context
The R5F104JGGFA#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode), plus multiply/divide/accumulate instructions and 1 MB address space. Its peripheral set includes Timer Array Unit (TAU) with 8 channels, 12-bit interval timer, RTC with calendar/alarm, and Event Link Controller (ELC) for hardware-triggered peripheral chaining.
Power management includes on-chip POR, 14-level LVD with interrupt/reset selection, and multiple low-power modes enabled by dedicated subsystem clocks. Serial interfaces comprise up to 4 UART/LIN channels (with LIN support), 4–10 I²C/simplified I²C channels, and 3–8 CSI (SPI-compatible) channels - all configurable via peripheral I/O redirection registers (PIOR0/1).

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F104JGAFB#30 | Same 96 KB flash/12 KB RAM, but 48-pin LFQFP (0.5 mm pitch); lacks P74/P75 KR4/KR5 keys and P140/P130 pins | Fits space-constrained designs needing fewer I/Os; not suitable for 52-pin footprint or key scan requirements | Select when board area is limited and KR4/KR5 key inputs or extra I/Os are unnecessary |
| R5F104JHAFB#30 | 128 KB flash/16 KB RAM, same 52-pin LFQFP; adds 4 KB more code space and 4 KB more RAM | Enables larger firmware (e.g., integrated bootloader + application), but increases cost and power in idle states | Choose when future firmware expansion or complex protocol stacks (e.g., CAN FD gateway) require headroom |
Compared with R5F104JGGFA#30, R5F104JGAFB#30 trades pin count and key-scan capability for compactness, while R5F104JHAFB#30 provides scalable memory for evolving firmware - both retain identical peripheral sets, low-power behavior, and G-grade temperature rating.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F104JGGFA#30?
The R5F104JGGFA#30 achieves a maximum operating frequency of 32 MHz using its high-speed on-chip oscillator, delivering 44 DMIPS of processing performance. This rating is measured under standard conditions (VDD = 1.8–5.5 V, TA = -40 to +105°C) and reflects the RL78 CPU core's 3-stage pipeline efficiency. The R5F104JGGFA#30 also supports lower-frequency operation down to 32.768 kHz for ultra-low-power RTC functions.
Does the R5F104JGGFA#30 support LIN bus communication, and which UART channel implements it?
Yes, the R5F104JGGFA#30 supports LIN bus communication via its UART peripherals - specifically UART2 (mapped to P13/TxD2 and P14/RxD2) and UART1 (P16/TI01 and P17/TI02) with LIN break-detection and sync-field generation hardware. The R5F104JGGFA#30 meets ISO 17987-4 physical layer timing requirements when paired with an external LIN transceiver, and its ELC can synchronize LIN frame transmission with timer events.
What are the data flash endurance and voltage requirements for rewriting the R5F104JGGFA#30?
The R5F104JGGFA#30 features 8 KB of data flash rated for 1,000,000 write/erase cycles (typical) with operation supported across the full VDD range of 1.8–5.5 V. Rewrites can occur in background operation (BGO) mode, allowing concurrent code execution from program flash. The R5F104JGGFA#30 requires no external high-voltage programming supply - all data flash operations use only the main VDD rail.
How many analog input channels does the R5F104JGGFA#30 ADC support, and what reference options are available?
The R5F104JGGFA#30 integrates a 10-bit successive-approximation ADC supporting up to 16 analog input channels (ANI0–ANI19, excluding reserved pins). It offers two reference voltage sources: the internal 1.45 V bandgap reference (stable across temperature and supply) and the externally supplied AVREFP/AVREFM pins. The R5F104JGGFA#30 ADC operates across the full 1.6–5.5 V VDD range, enabling accurate measurements even at low supply voltages.
Is the R5F104JGGFA#30 pin-compatible with other RL78/G14 variants in the same 52-pin LFQFP package?
Yes, the R5F104JGGFA#30 shares identical pinout, electrical characteristics, and mechanical dimensions with all other RL78/G14 52-pin LFQFP variants (e.g., R5F104JHAFB#30, R5F104JCGFA), including matching signal assignments for power, reset, clocks, and all primary peripherals. This allows direct substitution within the same package family when memory or temperature grade requirements change - provided PCB layout accommodates the exact #30 packaging specification (embossed tape).
