Product details
Overview
R5F104GJAFB#10 from Renesas is a 48-pin LFQFP, 0.5 mm pitch, industrial-grade (TA = −40 to +105°C) 16-bit RL78/G14 microcontroller with 192 KB flash, 8 KB data flash, 20 KB RAM, 52 I/O pins, and integrated peripherals including 12-channel 10-bit ADC, RTC, UART/SCI/I²C interfaces, and ultra-low-power operation (66 μA/MHz active, 0.60 μA in RTC+LVD mode). It targets battery-powered industrial sensors and motor control modules.
For engineers reviewing the R5F104GJAFB#10 datasheet, R5F104GJAFB#10 pinout, R5F104GJAFB#10 application, or R5F104GJAFB#10 equivalent, key selection criteria include its 192 KB code flash capacity, 48-pin LFQFP-0.5 mm package, industrial temperature rating (G-grade), real-time clock with calendar, and support for background data flash rewriting (BGO) at VDD = 1.8–5.5 V.
Technical Context
The R5F104GJAFB#10 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs min @ 32 MHz to 30.5 µs @ 32.768 kHz). It integrates a Data Transfer Controller (DTC) supporting normal, repeat, and block transfer modes triggered by 19–26 event sources via the Event Link Controller (ELC).
Its peripheral set includes up to 12 × 16-bit timers (TAU, RJ, RD, RG), 1 × 12-bit interval timer, 1 × real-time clock with alarm/calendar, 1 × watchdog timer, and serial interfaces: 3–4 UART/SCI channels (LIN-capable), 4–10 I²C/simplified I²C channels, and 3–8 CSI (SPI-compatible) channels - all mapped to dedicated pins per the 48-pin LFQFP pinout.

FAQ
What is the maximum operating frequency and corresponding current consumption of the R5F104GJAFB#10?
The R5F104GJAFB#10 operates up to 32 MHz with a typical active current of 66 μA/MHz, resulting in ~2.1 mA total at full speed and VDD = 3.3 V. Its high-accuracy on-chip oscillator supports ±1.0% tolerance across −20 to +85°C, eliminating need for external crystal in many applications. The R5F104GJAFB#10 also supports lower-frequency modes (e.g., 32.768 kHz RTC) consuming only 0.60 μA in HALT mode with RTC and LVD active.
Does the R5F104GJAFB#10 support in-system programming and secure firmware updates?
Yes, the R5F104GJAFB#10 supports full in-system programming via on-chip debug interface and includes flash shield window protection to restrict write access to designated memory regions. It enables secure firmware updates using boot swapping and background data flash rewriting (BGO), allowing the R5F104GJAFB#10 to execute application code while updating non-volatile storage - critical for fail-safe over-the-air (OTA) deployments in industrial environments.
How many analog input channels does the R5F104GJAFB#10 ADC support, and what reference options are available?
The R5F104GJAFB#10 integrates a 10-bit successive-approximation ADC with up to 16 analog input channels (ANI0–ANI19, excluding reserved pins). It supports both external reference voltage (AVREFP/AVREFM pins) and internal 1.45 V reference, enabling precise ratiometric or absolute measurements. The ADC operates across the full 1.6–5.5 V VDD range and includes built-in temperature sensor for environmental compensation - all accessible without external components on the R5F104GJAFB#10.
What serial communication interfaces are available on the R5F104GJAFB#10, and which support LIN bus protocol?
The R5F104GJAFB#10 provides three UART/SCI channels (U00, U11, U20), four to ten I²C/simplified I²C channels, and three to eight CSI (SPI-compatible) channels. Among these, UART channel U00 (pins P50/P51) and U11 (pins P11/P12) explicitly support LIN 2.2 protocol with hardware sync-break detection, checksum generation, and identifier filtering - enabling direct integration into automotive body electronics or industrial LIN networks without external transceivers.
Is the R5F104GJAFB#10 pin-compatible with other RL78/G14 variants in the same 48-pin LFQFP package?
Yes, all RL78/G14 devices in the 48-pin LFQFP-0.5 mm package (including R5F104GJAFB#10, R5F104GHAFB#10, R5F104GKAFB#10, and R5F104GLAFB#10) share identical pinouts and electrical characteristics. This allows drop-in replacement across memory variants - for example, upgrading from 128 KB to 192 KB flash requires no PCB change, only firmware reflash and configuration adjustment. The R5F104GJAFB#10 maintains full functional and mechanical compatibility within this package family.
