Product details
Overview
R5F101GJDFB#30 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 at up to 32 MHz (41 DMIPS), featuring ultra-low-power HALT/STOP/SNOOZE modes (0.57 μA RTC+LVD), integrated 10-bit ADC (26 channels), real-time clock, and UART/I²C/CSI interfaces - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F101GJDFB#30 datasheet, R5F101GJDFB#30 pinout, R5F101GJDFB#30 application, or R5F101GJDFB#30 equivalent, key selection criteria include its 48-pin LFQFP-0.5mm package, absence of on-chip data flash (R5F101x series), -40°C to +85°C industrial temperature grade (D suffix), and support for background data flash rewriting via BGO.
Technical Context
The R5F101GJDFB#30 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 integrates a 12-bit interval timer, calendar-based RTC with alarm and correction, and watchdog timer powered by dedicated low-speed oscillator.
Peripheral integration includes 8–16 channels of 16-bit timers, 3–10 I²C/Simplified I²C channels, 2–4 UART/LIN channels, 2–8 CSI channels, and DMA controller with 2/4 channels enabling 2-clock transfers between SFR and RAM - all optimized for deterministic real-time control in resource-constrained embedded systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100GJDFB#30 | Includes 8 KB on-chip data flash; otherwise identical pinout, peripherals, and code flash size | Required where field firmware updates or parameter storage demand nonvolatile data memory | Select when persistent configuration storage or OTA update staging area is needed |
| R5F101GJAFB#30 | Same core/peripherals but in 48-pin LQFP-0.8 mm pitch (PLQP0048KF-A); differs in mechanical footprint and thermal pad presence | Used where legacy PCB layout uses standard 0.8 mm pitch or requires exposed thermal pad for higher ambient operation | Choose for compatibility with existing LQFP-0.8 mm land patterns or enhanced thermal dissipation needs |
Compared with R5F101GJDFB#30, R5F100GJDFB#30 adds data flash for robust parameter retention but increases cost and write-cycle management overhead, while R5F101GJAFB#30 trades the fine-pitch LFQFP for easier assembly and better thermal performance at the expense of board space.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F101GJDFB#30?
The R5F101GJDFB#30 operates at up to 32 MHz using the high-speed on-chip oscillator, delivering 41 DMIPS performance. Its minimum instruction execution time is 0.03125 μs under this condition, and it supports dynamic clock switching down to 32.768 kHz for ultra-low-power RTC operation.
Does the R5F101GJDFB#30 include on-chip data flash memory?
No, the R5F101GJDFB#30 does not include on-chip data flash memory. As indicated by the "101" prefix in the part number per Renesas documentation, this variant provides only code flash (192 KB) and 16 KB RAM. Data flash functionality is present only in "100"-series variants like R5F100GJDFB#30.
What package type and pin pitch does the R5F101GJDFB#30 use?
The R5F101GJDFB#30 uses a 48-pin LFQFP package (PLQP0048KB-B) with 7 mm × 7 mm body size and 0.5 mm pin pitch. The "#30" suffix denotes tray packaging, and the "FB" in the part number explicitly identifies the LFQFP-0.5 mm variant per Renesas' ordering nomenclature.
What is the operating temperature range specified for the R5F101GJDFB#30?
The R5F101GJDFB#30 is rated for industrial operation from –40°C to +85°C, as confirmed by the "D" suffix in its part number per Renesas' RL78/G13 documentation. This distinguishes it from "A"-grade (–40°C to +85°C consumer) and "G"-grade (–40°C to +105°C industrial) variants.
How many analog input channels does the R5F101GJDFB#30 support, and what is the ADC resolution?
The R5F101GJDFB#30 supports up to 26 analog input channels with a 10-bit successive-approximation ADC. It includes internal 1.45 V reference voltage and a temperature sensor, both accessible only in HS (high-speed main) mode per the RL78/G13 datasheet.
