Product details
Overview
R5F104GKAFB#30 from Renesas is a 48-pin LFQFP, 0.5 mm pitch, industrial-grade (G) 16-bit RL78/G14 microcontroller with 256 KB flash, 8 KB data flash, 24 KB RAM, and operation up to 32 MHz delivering 44 DMIPS - deployed in battery-powered sensor nodes requiring ultra-low-power RTC + LVD monitoring at -40°C to +105°C.
For engineers reviewing the R5F104GKAFB#30 datasheet, R5F104GKAFB#30 pinout, R5F104GKAFB#30 application, or R5F104GKAFB#30 equivalent, key selection criteria include its 0.60 μA STOP mode current, integrated 10-bit ADC (20-channel), dual UART/LIN support, hardware DTC/ELC for deterministic peripheral chaining, and LFQFP-48 package compatibility with high-density industrial PCB layouts.
Technical Context
The R5F104GKAFB#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz), plus multiply/divide/accumulate instructions and 1 MB address space. It integrates a 12-bit interval timer, calendar-based real-time clock with alarm/correction, and watchdog timer with dedicated low-speed oscillator.
Peripheral subsystems include eight 16-bit timer channels (TAU/Timer RJ/RD/RG), four to ten I²C/Simplified I²C channels, three or four UART/LIN interfaces, three to eight CSI (SPI-compatible) channels, and an 8/10-bit ADC with internal 1.45 V reference and temperature sensor - all configurable via Event Link Controller (ELC) for interrupt-free signal routing.

FAQ
What is the operating temperature range for the R5F104GKAFB#30?
The R5F104GKAFB#30 is rated for industrial operation from -40°C to +105°C (G-grade), validated across its full voltage range (1.6 V to 5.5 V). This makes it suitable for under-hood automotive modules, factory-floor controllers, and outdoor utility infrastructure where ambient extremes are expected. All specifications - including flash endurance, ADC accuracy, and oscillator stability - are guaranteed within this range.
Does the R5F104GKAFB#30 support in-system programming via standard interfaces?
Yes, the R5F104GKAFB#30 supports full in-system programming using Renesas' standard single-wire debug (SWD) interface via the TOOL0 pin. It also enables self-programming of both code and data flash with boot swapping and flash shield window protection - allowing secure firmware updates in the field without requiring external programmers or chip removal.
How many UART/LIN interfaces does the R5F104GKAFB#30 include?
The R5F104GKAFB#30 integrates four UART channels, all supporting LIN 2.2 physical layer compliance. Two of these (UART0 and UART2) are designated for LIN master/slave operation with automatic sync-break detection and checksum handling - enabling direct connection to LIN transceivers for automotive body networks or appliance sub-systems.
What is the maximum ADC sampling rate achievable on the R5F104GKAFB#30?
The R5F104GKAFB#30's 10-bit ADC achieves a maximum conversion time of 1.2 μs per sample (up to ~833 kSPS) when using the internal high-speed clock and optimized trigger sources (e.g., timer compare match). Real-world sustained throughput depends on channel count and scan mode, but continuous 20-channel sampling at 100 kSPS is fully supported with DTC offloading.
Is the R5F104GKAFB#30 pin-compatible with other RL78/G14 48-pin variants?
Yes, the R5F104GKAFB#30 shares identical pinout, package dimensions (LFQFP-48, 7×7 mm, 0.5 mm pitch), and electrical characteristics with all other RL78/G14 48-pin G-grade parts - including R5F104GLAFB#30 and R5F104GJAFB#30. This enables drop-in memory scalability or cost optimization without PCB redesign or firmware modification.
