Product details
Overview
R5F100GJAFB#X0 from Renesas is a 48-pin LFQFP-0.5mm-pitch 16-bit RL78/G13 microcontroller with 192 KB flash, 8 KB data flash, 16 KB RAM, and industrial-grade operation up to +105°C. It delivers 41 DMIPS at 32 MHz, consumes 66 μA/MHz active and 0.57 μA in RTC+LVD mode, and integrates UART, I²C, SPI, 16-bit timers, 10-bit ADC (26 channels), and real-time clock - used in motor control, sensor hubs, and smart metering.
For engineers reviewing the R5F100GJAFB#X0 datasheet, R5F100GJAFB#X0 pinout, R5F100GJAFB#X0 application, or R5F100GJAFB#X0 equivalent, key selection criteria include its 48-pin LFQFP package, 192 KB code flash with self-programming, 10-bit ADC with internal temperature sensor, ultra-low-power STOP/HALT/SNOOZE modes, and support for LIN-bus via UART.
Technical Context
The R5F100GJAFB#X0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It supports background operation during data flash rewriting and includes a dedicated low-speed on-chip oscillator for watchdog timer operation.
Its peripheral set includes up to 16 channels of 16-bit timer, 1 channel of 12-bit interval timer, 1 calendar-based real-time clock with alarm and correction, and 3–10 channels of I²C/Simplified I²C - all configurable without external components. The device uses VDD = 1.6–5.5 V and features 14-level voltage detector (LVD) with selectable interrupt/reset behavior.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101GJAFB#X0 | No data flash memory (0 KB); same core, peripherals, and package | Not suitable for applications requiring nonvolatile parameter storage or firmware update history | Select when data logging or field-upgrade capability is unnecessary and BOM cost reduction is critical |
| R5F100GJAFP#V0 | LQFP-48, 0.8 mm pitch instead of LFQFP-48, 0.5 mm pitch; identical electrical specs | Requires PCB layout change due to larger pad pitch and footprint; not drop-in compatible | Choose only if existing board design uses 0.8 mm pitch LQFP or assembly process lacks fine-pitch capability |
Compared with R5F100GJAFB#X0, R5F101GJAFB#X0 removes data flash to reduce cost and die size but sacrifices field-update resilience, while R5F100GJAFP#V0 retains full functionality at the expense of higher PCB real estate and less dense routing - making R5F100GJAFB#X0 optimal for space-constrained, upgrade-aware industrial designs.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F100GJAFB#X0?
The R5F100GJAFB#X0 operates at up to 32 MHz using its high-speed on-chip oscillator and achieves 41 DMIPS (Dhrystone MIPS) at that frequency. This performance level is confirmed in the RL78/G13 datasheet (R01DS0131EJ0380 Rev.3.80) and reflects optimized CISC execution with 3-stage pipeline and cache-like register banking.
Does the R5F100GJAFB#X0 support LIN bus communication, and which peripheral handles it?
Yes, the R5F100GJAFB#X0 supports LIN 2.2 communication through UART0 (pins P30/P31), which includes hardware-assisted sync-break detection, checksum generation, and identifier filtering. This eliminates need for external LIN transceivers in basic node implementations and is documented in Section 1.1 Features and Section 17.3 UART of the datasheet.
What is the data flash endurance and voltage range for reprogramming the R5F100GJAFB#X0?
The R5F100GJAFB#X0 provides 8 KB of data flash rated for 1,000,000 write/erase cycles (typical) with programming voltage matching the main supply: VDD = 1.8–5.5 V. Background operation (BGO) allows concurrent code execution during rewrites, and the flash library reserves RAM starting at address FAF00H per the datasheet's memory map section.
How does the R5F100GJAFB#X0 achieve ultra-low power consumption in STOP mode?
The R5F100GJAFB#X0 achieves 0.57 μA STOP mode current by powering down the CPU, flash, and most peripherals while retaining RTC operation, LVD monitoring, and SRAM contents. Only the 32.768 kHz sub-system clock and associated circuitry remain active - a configuration validated in the "Power Management" section of the RL78/G13 datasheet.
Is the R5F100GJAFB#X0 pin-compatible with other RL78/G13 variants in the same 48-pin LFQFP package?
Yes, all RL78/G13 devices in the 48-pin LFQFP-0.5mm package (e.g., R5F100GKAFB#X0, R5F100GHAFB#X0) share identical pinouts and mechanical footprint. Function allocation per pin is consistent across the family, enabling hardware reuse when migrating between flash/RAM configurations - as confirmed in the "Pin Configuration" chapter of the datasheet.
