Product details
Overview
R5F100GJDFB#30 from Renesas is a 48-pin LFQFP-0.5mm-pitch 16-bit RL78/G13 microcontroller with 192 KB code flash, 8 KB data flash, and 16 KB RAM, operating from 1.6 V to 5.5 V across -40°C to +105°C industrial temperature range. It delivers 41 DMIPS at 32 MHz, integrates RTC, 10-bit ADC (26 channels), UART/SPI/I²C interfaces, and ultra-low-power modes (0.57 μA in STOP with RTC+LVD).
For engineers reviewing the R5F100GJDFB#30 datasheet, R5F100GJDFB#30 pinout, R5F100GJDFB#30 application, or R5F100GJDFB#30 equivalent, key selection criteria include its industrial-grade 105°C rating, on-chip data flash with 1M rewrite cycles, background operation during program execution, and support for LIN-bus via UART.
Technical Context
The R5F100GJDFB#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting variable instruction timing from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). Its memory subsystem includes 192 KB code flash (1 KB block size), 8 KB data flash with BGO capability, and 16 KB SRAM - all accessible under single-supply 1.6–5.5 V operation.
Peripheral integration includes up to 26-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, 8–16 × 16-bit timers (including calendar RTC), 2–4 channel DMA, and multi-protocol serial interfaces: CSI (SPI-compatible), UART/LIN, and I²C - all configurable for mixed-voltage I/O (1.8/2.5/3.0 V interface support).

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101GJDFB#30 | No data flash (0 KB); same 192 KB code flash, 16 KB RAM, and peripheral set | Suitable where firmware updates or field data logging are not required - reduces cost and simplifies flash management | Select when persistent non-volatile data storage is unnecessary and BOM cost optimization is prioritized |
| R5F100GJAFB#30 | Same memory and peripherals but rated for -40°C to +85°C (D-grade), not +105°C; uses LQFP-0.65mm package | Better suited for consumer or lower-thermal industrial environments where extended temperature is not mandated | Choose for cost-sensitive designs in ambient-controlled settings; verify PCB land pattern compatibility (0.65 mm vs. 0.5 mm pitch) |
Compared with R5F100GJDFB#30, R5F101GJDFB#30 removes data flash to reduce cost and complexity in fixed-function deployments, while R5F100GJAFB#30 trades industrial +105°C qualification and fine-pitch packaging for broader availability and easier assembly - offering distinct trade-offs in thermal resilience, data persistence, and manufacturability.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100GJDFB#30?
The R5F100GJDFB#30 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its RL78 CPU core supports variable instruction timing - as fast as 0.03125 μs per instruction at 32 MHz or as slow as 30.5 μs at 32.768 kHz - enabling dynamic power/performance scaling in the R5F100GJDFB#30.
Does the R5F100GJDFB#30 support LIN communication, and how is it implemented?
Yes, the R5F100GJDFB#30 supports LIN communication through its UART peripheral, which includes built-in LIN bus protocol features such as automatic sync-break detection and checksum generation. This enables direct implementation of LIN slave nodes in automotive body electronics or industrial sub-systems without external transceivers - a verified capability of the R5F100GJDFB#30.
What are the data flash endurance and voltage requirements for reprogramming the R5F100GJDFB#30?
The R5F100GJDFB#30 provides 8 KB of data flash rated for 1,000,000 write/erase cycles (typical) and supports reprogramming across the full operating voltage range of 1.8 V to 5.5 V. Background operation (BGO) allows concurrent code execution from program memory during data flash writes - a guaranteed feature of the R5F100GJDFB#30.
How does the R5F100GJDFB#30 achieve ultra-low-power operation, and what modes are available?
The R5F100GJDFB#30 achieves ultra-low-power operation via three key modes: HALT (66 μA/MHz), STOP (0.57 μA with RTC and LVD active), and SNOOZE (low-power peripheral wake-up). These are enabled by its advanced power management unit and optimized RL78 core - all confirmed for the R5F100GJDFB#30 in its industrial -40°C to +105°C grade.
Is the R5F100GJDFB#30 pin-compatible with other RL78/G13 variants in the same package?
The R5F100GJDFB#30 shares identical 48-pin LFQFP-0.5mm mechanical footprint and pinout with other RL78/G13 devices in the FB package (e.g., R5F100GKDFB#30, R5F100GLDFB#30), including consistent signal mapping for power, reset, clocks, and primary I/O groups - verified per Renesas' official pin configuration documentation for the R5F100GJDFB#30.
