Product details
Overview
R5F100PJGFB#X0 from Renesas is a 100-pin LFQFP-packaged RL78/G13 16-bit MCU with 96 KB flash, 8 KB data flash, 8 KB RAM, 52-channel A/D converter, and real-time clock-designed for industrial temperature range (−40°C to +105°C) in low-power motor control and sensor interface applications.
For engineers reviewing the R5F100PJGFB#X0 datasheet, R5F100PJGFB#X0 pinout, R5F100PJGFB#X0 application, or R5F100PJGFB#X0 equivalent, key selection criteria include its 0.5-mm pitch LFQFP-100 package, integrated RTC with calendar/alarm, background data flash rewrite capability, and ultra-low power HALT/STOP/SNOOZE modes supporting battery-backed operation.
Technical Context
The R5F100PJGFB#X0 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 μs (@32 MHz high-speed oscillator) to 30.5 μs (@32.768 kHz subsystem clock). It integrates dual serial interfaces-including up to 4 UART/LIN channels and 10 I²C/Simplified I²C channels-for mixed-protocol communication in embedded control systems.
Its power architecture includes on-chip POR, selectable 14-level LVD, and true low-power operation: 66 μA/MHz active current and 0.57 μA in RTC+LVD-only mode. The device supports self-programming with boot swap and flash shield window functions, enabling secure firmware updates without external programming hardware.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100PJDFB#X0 | Same 96 KB flash, 8 KB data flash, 8 KB RAM, but rated for −40°C to +85°C (D-grade) | Not qualified for +105°C environments; suitable for consumer or lower-ambient industrial use | Select when full industrial temperature range is not required and cost optimization is prioritized |
| R5F100PJAFB#X0 | Same package and memory, but lacks data flash (0 KB); uses same 96 KB code flash only | Cannot perform background data logging or field firmware parameter updates without external EEPROM | Choose when persistent non-volatile storage is handled externally or not needed |
Compared with R5F100PJGFB#X0, the D-grade R5F100PJDFB#X0 sacrifices extended temperature capability for lower unit cost, while the A-grade R5F100PJAFB#X0 removes data flash entirely-reducing flexibility in field-updatable applications but lowering BOM count where external storage suffices.

FAQ
What is the maximum operating frequency and corresponding current consumption of the R5F100PJGFB#X0?
The R5F100PJGFB#X0 operates up to 32 MHz using its high-accuracy on-chip oscillator (±1.0% over −40°C to +85°C). At this frequency, typical active current is 66 μA per MHz, resulting in ~2.1 mA total at 32 MHz with all peripherals enabled. In STOP mode with only RTC and LVD active, current drops to 0.57 μA-critical for battery longevity in metering and sensor nodes.
Does the R5F100PJGFB#X0 support in-system programming and secure firmware updates?
Yes, the R5F100PJGFB#X0 supports full in-system programming via on-chip debug interface and includes secure self-programming features: boot swap functionality allows safe firmware updates with rollback capability, and the flash shield window prevents unauthorized access to protected code regions during runtime or debugging.
How many analog input channels does the R5F100PJGFB#X0 provide, and what is their resolution?
The R5F100PJGFB#X0 integrates a 10-bit successive-approximation A/D converter with 52 configurable analog input channels. It supports internal reference voltage (1.45 V) and on-chip temperature sensor-enabling accurate voltage, current, and thermal measurements without external components in motor control and environmental monitoring applications.
What serial communication interfaces are available on the R5F100PJGFB#X0?
The R5F100PJGFB#X0 provides up to 4 UART/LIN channels (supporting LIN 2.2A), up to 10 I²C/Simplified I²C channels, and up to 8 CSI (SPI-compatible) channels. This multi-protocol flexibility allows direct connection to diverse peripherals-including automotive sensors (LIN), touch controllers (I²C), and display drivers (SPI)-without external bridge ICs.
Is the R5F100PJGFB#X0 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 100-pin LFQFP-0.5mm package-including R5F100PJGFB#X0, R5F100PJDFB#X0, and R5F100PJAFB#X0-share identical pinouts and mechanical footprint. This enables drop-in replacement across temperature grades and memory configurations, simplifying design reuse and qualification across product families.
