Product details
Overview
R5F100GJAFB#10 from Renesas is a 48-pin LFQFP-packaged 16-bit RL78/G13 microcontroller with 192 KB flash, 8 KB data flash, and 16 KB RAM, operating from 1.6–5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power modes (0.57 μA RTC+LVD), 10-bit ADC (26 channels), RTC, UART/SPI/I²C interfaces, and hardware multiplier/divider - deployed in industrial sensor nodes and battery-powered control systems.
For engineers reviewing the R5F100GJAFB#10 datasheet, R5F100GJAFB#10 pinout, R5F100GJAFB#10 application, or R5F100GJAFB#10 equivalent, key selection criteria include its -40°C to +105°C industrial temperature grade (G suffix), LFQFP-48 0.5-mm pitch package (FB), integrated data flash with 1M-cycle endurance, and support for background operation during flash rewriting.
Technical Context
The R5F100GJAFB#10 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting variable instruction execution time (0.03125 μs @32 MHz to 30.5 μs @32.768 kHz) and 1 MB address space. It integrates dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) and dedicated low-speed oscillator for watchdog/RTC.
Its peripheral set includes 8-channel 16-bit timers, 12-bit interval timer, calendar RTC with alarm/correction, 2–4 DMA channels, and serial interfaces with LIN-bus support in UART mode - all managed via configurable SFRs and interrupt vectors mapped to 128 priority levels.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F100GJAFB#10?
The R5F100GJAFB#10 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. This benchmark reflects the RL78 core's 3-stage pipeline efficiency and is measured under standard conditions (VDD = 3.3 V, TA = 25°C). The R5F100GJAFB#10 maintains full peripheral functionality at this speed, including ADC conversion and serial communication.
Does the R5F100GJAFB#10 support background data flash rewriting while executing code from program memory?
Yes, the R5F100GJAFB#10 supports Background Operation (BGO) for data flash. This allows the CPU to execute instructions from code flash while simultaneously rewriting data flash memory - enabling seamless data logging, configuration updates, or firmware patching without system interruption. The R5F100GJAFB#10 guarantees 1,000,000 write/erase cycles for its 8 KB data flash.
What are the key differences between the R5F100GJAFB#10 and R5F101GJAFB#10?
The R5F100GJAFB#10 includes 8 KB of on-chip data flash, whereas the R5F101GJAFB#10 omits data flash entirely. All other specifications - core, peripherals, package (LFQFP-48), temperature grade (-40°C to +105°C), and pinout - are identical. Therefore, the R5F100GJAFB#10 is selected when embedded nonvolatile parameter storage or firmware logging is required, while R5F101GJAFB#10 suits applications relying on external memory.
Which serial communication protocols are supported by the R5F100GJAFB#10, and how many channels are available?
The R5F100GJAFB#10 supports three serial protocols: CSI (SPI-compatible, up to 8 channels), UART/LIN (up to 4 channels), and I²C/Simplified I²C (up to 10 channels). Each channel is independently configurable via SFRs, and UART instances support LIN 2.2 physical layer timing for automotive body electronics. The R5F100GJAFB#10 does not integrate CAN or USB controllers.
What packaging and lead pitch does the R5F100GJAFB#10 use, and is it RoHS-compliant?
The R5F100GJAFB#10 uses a 48-pin LFQFP package (7 mm × 7 mm footprint) with 0.5 mm lead pitch, designated by the "FB" suffix in the part number. It is fully RoHS-compliant and rated for moisture sensitivity level 3 (MSL3), requiring bake conditioning before reflow if exposed beyond floor life. The R5F100GJAFB#10 is supplied in trays (#V0 marking) per Renesas standard packaging.
