Product details
Overview
R5F100GJDFB#X0 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 V to 5.5 V across -40°C to +105°C. It delivers 41 DMIPS at 32 MHz, integrates RTC, 10-bit ADC (26 channels), UART/I²C/CSI interfaces, and ultra-low-power modes (0.57 μA in STOP with RTC+LVD).
For engineers reviewing the R5F100GJDFB#X0 datasheet, R5F100GJDFB#X0 pinout, R5F100GJDFB#X0 application, or R5F100GJDFB#X0 equivalent, key selection criteria include industrial-temperature operation, on-chip data flash rewrite endurance (1M cycles), background operation capability, and support for LIN-bus via UART.
Technical Context
The R5F100GJDFB#X0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It includes a 2-channel DMA controller with 2-clock transfers between SFR and RAM, and a hardware multiplier/divider supporting signed/unsigned 16×16→32, 32÷32→32, and MAC operations.
Power management features include on-chip POR, 14-level LVD with interrupt/reset selection, HALT/STOP/SNOOZE low-power modes, and a high-accuracy ±1.0% on-chip oscillator (32 MHz to 1 MHz). The device supports self-programming with boot swap and flash shield window functions, and background operation during data flash rewriting.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for R5F100GJDFB#X0?
The R5F100GJDFB#X0 operates at up to 32 MHz and delivers 41 DMIPS (Dhrystone MIPS) under standard test conditions. This performance level is achieved using the RL78 CPU core's 3-stage pipeline and optimized instruction set, enabling deterministic real-time response for motor control, sensor processing, and communication stack execution in the R5F100GJDFB#X0.
Does R5F100GJDFB#X0 include on-chip data flash, and what is its endurance specification?
Yes, the R5F100GJDFB#X0 includes 8 KB of on-chip data flash memory rated for 1,000,000 write/erase cycles (typical). It supports background operation (BGO), allowing program execution from code flash while rewriting data flash - a key capability for firmware updates and parameter logging in the R5F100GJDFB#X0 without halting application logic.
What is the operating temperature range certified for R5F100GJDFB#X0, and which industrial standards does it meet?
The R5F100GJDFB#X0 is rated for -40°C to +105°C ambient operation (G-grade), qualifying it for industrial and automotive under-hood applications. It meets JEDEC JESD22-A108 reliability standards for temperature cycling and is manufactured under Renesas' AEC-Q100-compliant process flow - though full AEC-Q100 qualification requires additional part-specific testing beyond the base R5F100GJDFB#X0 specification.
How many analog input channels does the 10-bit ADC in R5F100GJDFB#X0 support, and are internal references available?
The R5F100GJDFB#X0 integrates a 10-bit successive-approximation ADC with up to 26 configurable analog input channels. It includes an internal 1.45 V reference voltage and supports external reference inputs (AVREFP/AVREFM), enabling high-accuracy measurements across varying supply conditions - a critical feature for precision sensing in the R5F100GJDFB#X0.
Is R5F100GJDFB#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 package (e.g., R5F100GxAFB, R5F100GxDFB, R5F100GxGFB) share identical pinouts and mechanical dimensions. This allows drop-in replacement across memory variants (192 KB/128 KB/96 KB flash) and data flash configurations (8 KB/4 KB) - provided software is adapted for differences in memory map and peripheral enablement in the R5F100GJDFB#X0.
