Product details
Overview
R5F104JFAFA#30 from Renesas is a 52-pin LQFP-0.65 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 V to 5.5 V at -40°C to +105°C. It delivers 44 DMIPS at 32 MHz, features ultra-low-power HALT/STOP/SNOOZE modes (0.60 μA RTC+LVD), integrated 10-bit ADC (20 ch), UART/LIN, I²C, SPI, RTC, and hardware DTC/ELC for sensor hub and motor control in battery-powered industrial equipment.
For engineers reviewing the R5F104JFAFA#30 datasheet, R5F104JFAFA#30 pinout, R5F104JFAFA#30 application, or R5F104JFAFA#30 equivalent, key selection criteria include its 52-pin LQFP package with 20-channel ADC, LIN-capable UARTs, real-time clock with calendar/alarm, and support for background data flash rewriting - critical for firmware-over-the-air updates and embedded energy metering.
Technical Context
The RL78/G14 core implements a 3-stage CISC pipeline with configurable instruction timing (0.03125 µs @ 32 MHz to 30.5 µs @ 32.768 kHz), multiply/divide/accumulate instructions, and 1 MB address space. Its peripheral set includes Timer Array Unit (TAU) with 8 channels, 12-bit interval timer, watchdog timer, and dual comparator units supporting window mode and internal/external reference selection.
Power management integrates on-chip POR, 14-level LVD with interrupt/reset options, and REGC-based voltage regulation requiring external 0.47–1 µF decoupling. The Event Link Controller (ELC) enables direct peripheral-to-peripheral event triggering without CPU intervention, reducing latency in time-critical control loops such as BLDC commutation or PLC I/O scanning.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F104JFAFA#30?
The R5F104JFAFA#30 operates at up to 32 MHz with a measured performance of 44 DMIPS. This value is derived from the RL78/G14 core's 3-stage pipeline architecture and instruction mix benchmarking per EEMBC CoreMark methodology. The R5F104JFAFA#30 achieves this performance while maintaining ultra-low active current of 66 μA/MHz, making it suitable for high-efficiency industrial control tasks where processing throughput and power coexist.
Does the R5F104JFAFA#30 support LIN bus communication, and how is it implemented?
Yes, the R5F104JFAFA#30 supports LIN bus communication through its UART peripherals configured in LIN mode. Specifically, UART0, UART1, and UART2 all include LIN-break detection, sync field generation, and checksum calculation hardware. The R5F104JFAFA#30 uses its on-chip 14-level voltage detector (LVD) and real-time clock to meet LIN timing tolerances, and its ELC can synchronize LIN frame transmission with timer events - enabling robust slave-node implementation in automotive body electronics and industrial sub-networks.
What are the data flash endurance and voltage requirements for rewriting the R5F104JFAFA#30?
The R5F104JFAFA#30 features 8 KB of data flash rated for 1,000,000 write/erase cycles (typical) with guaranteed operation across VDD = 1.8 V to 5.5 V. Rewrites occur in 1 KB blocks and support background operation (BGO), allowing CPU execution from main flash during data flash programming. The R5F104JFAFA#30 requires no external high-voltage supply - all programming voltages are generated internally, simplifying system design for field-upgradable firmware and parameter storage.
How does the R5F104JFAFA#30 manage ultra-low-power operation in STOP mode?
The R5F104JFAFA#30 achieves 0.60 μA typical current in STOP mode by disabling the main clock, CPU, and most peripherals while retaining power to the RTC, LVD, and RAM retention circuitry. Wake-up sources include RTC alarm, external interrupts (INTP0–INTP9), and comparator events. The R5F104JFAFA#30 maintains full register context and RAM contents across STOP entry/exit, enabling sub-10 µs wake-up latency - essential for duty-cycled sensor nodes and energy-harvesting systems.
What development tools and debug interfaces are supported by the R5F104JFAFA#30?
The R5F104JFAFA#30 supports Renesas E2 emulator Lite and E2 emulator for full JTAG debugging, flash programming, and real-time trace. It includes on-chip debug functionality compliant with IEEE 1149.1, with dedicated TOOL0/TOOLRxD/TOOLTxD pins for SWD/JTAG. The R5F104JFAFA#30 also supports Renesas CS+ IDE and e² studio with GCC-based toolchain, and its bootloader supports UART-based firmware updates without external programmer - accelerating prototyping and field service workflows.
