Product details
Overview
R5F100GJAFB#30 from Renesas is a 48-pin LFQFP-packaged 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB data flash, 12 KB RAM, and industrial-grade operation up to +105°C. It integrates a real-time clock, 10-bit ADC (26 channels), UART/LIN, I²C, CSI, 16-bit timers, DMA, and ultra-low-power modes (0.57 μA in RTC+LVD mode) for embedded control in HVAC, motor drives, and smart sensors.
For engineers reviewing the R5F100GJAFB#30 datasheet, R5F100GJAFB#30 pinout, R5F100GJAFB#30 application, or R5F100GJAFB#30 equivalent, key selection criteria include its 48-pin LFQFP-0.5 mm pitch package, 128 KB code flash with self-programming and flash shield window, 10-bit ADC with internal temperature sensor, LIN-compliant UART, and support for STOP/HALT/SNOOZE low-power states.
Technical Context
The R5F100GJAFB#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 features dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, selectable 1–32 MHz) and dedicated low-speed oscillator for watchdog and RTC.
Its peripheral set includes 8-channel 16-bit timers, 12-bit interval timer, calendar-mode RTC with alarm/correction, 2–4 channel DMA, 16×16/32÷32 hardware multiplier/divider, and 3–10 channel I²C/Simplified I²C - all operating across 1.6–5.5 V supply and -40°C to +105°C ambient range.

FAQ
What is the maximum operating frequency and DMIPS rating of the R5F100GJAFB#30?
The R5F100GJAFB#30 operates at up to 32 MHz with a measured performance of 41 DMIPS. This is achieved using the high-speed on-chip oscillator (±1.0% accuracy) and reflects integer instruction throughput under benchmark conditions defined in the RL78 architecture specification. The R5F100GJAFB#30 maintains this performance across its full 1.6–5.5 V supply and -40°C to +105°C operating range.
Does the R5F100GJAFB#30 include an integrated temperature sensor?
Yes, the R5F100GJAFB#30 includes a factory-calibrated on-chip temperature sensor accessible via the 10-bit ADC. It is enabled only in HS (high-speed main) mode and provides a voltage output proportional to die temperature, usable for thermal monitoring, system derating, or ambient sensing without external components. The R5F100GJAFB#30 datasheet specifies its accuracy and conversion formula in Section 26.5.
What low-power modes does the R5F100GJAFB#30 support, and what is its lowest current consumption?
The R5F100GJAFB#30 supports HALT, STOP, and SNOOZE modes. Its lowest active current is 0.57 μA in STOP mode with only RTC and LVD operational - verified at VDD = 3.0 V and TA = 25°C. This makes the R5F100GJAFB#30 suitable for battery-backed real-time logging and wake-on-event applications where multi-year operation is required.
Is the R5F100GJAFB#30 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100GJAFB#30 is pin-compatible with all 48-pin LFQFP RL78/G13 variants sharing the FB suffix (e.g., R5F100FAFB#30, R5F100GKAFB#30), as confirmed by the common pin configuration diagram in the R01DS0131EJ0380 datasheet. Pin functions, power domains, and peripheral mappings remain consistent across this package group, enabling drop-in replacement within the same memory/peripheral subset.
What debug and programming interfaces are supported by the R5F100GJAFB#30?
The R5F100GJAFB#30 supports on-chip debugging via the single-wire debug interface (SWD) using the TOOLx pins (P11/TOOLRxD and P10/TOOLTxD), compatible with Renesas E2 emulator and CS+ IDE. It also supports self-programming via on-chip bootloader, allowing firmware updates through UART or custom host protocols without external programmers. All debug features are fully implemented in the R5F100GJAFB#30 silicon.
