Product details
Overview
R5F100GJGFB#V0 from Renesas is a 48-pin LFQFP-packaged 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB data flash, 12 KB RAM, 52 MHz max CPU speed (41 DMIPS), and industrial-grade -40°C to +105°C operation. It integrates RTC, 10-bit ADC (26 channels), UART/SPI/I²C interfaces, 16-bit timers, and ultra-low-power modes (0.57 μA in STOP with RTC+LVD) for embedded control in HVAC, motor drives, and industrial sensors.
For engineers reviewing the R5F100GJGFB#V0 datasheet, R5F100GJGFB#V0 pinout, R5F100GJGFB#V0 application, or R5F100GJGFB#V0 equivalent, key selection criteria include its G-grade temperature rating, 48-pin LFQFP-0.5mm package, integrated data flash with background operation, and support for SNOOZE mode wake-up via serial interface - critical for battery-powered industrial edge nodes.
Technical Context
The R5F100GJGFB#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting variable instruction execution time from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). Its memory subsystem includes 128 KB code flash (1 KB block size), 8 KB data flash with 1M-cycle endurance and background rewrite capability, and 12 KB on-chip RAM.
Peripheral integration centers on low-power system control: dual-channel DMA, 16-bit timer array (12 channels), real-time clock with calendar/alarm/correction, 10-bit ADC with internal reference and temperature sensor, and multi-protocol serial interfaces including CSI (SPI-compatible), UART/LIN, and I²C - all configurable under HALT/STOP/SNOOZE power modes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101GJGFB#V0 | No data flash (0 KB); identical core, peripherals, and package; lower cost where parameter storage is handled externally. | Suitable for cost-sensitive designs with external EEPROM or where firmware parameters are static. | Select when data flash is unnecessary and BOM cost reduction is prioritized over field-upgradable configuration storage. |
| R5F100GJGFA#V0 | LQFP-0.65 mm pitch (48-pin) instead of LFQFP-0.5 mm; same memory, peripherals, and temperature grade. | Better suited for legacy PCB layouts using standard-pitch LQFP footprints and hand-soldering processes. | Choose for compatibility with existing LQFP-0.65 mm assembly lines or when finer pitch reflow capability is unavailable. |
Compared with R5F100GJGFB#V0, R5F101GJGFB#V0 removes data flash to reduce cost and die size while retaining full functional compatibility for fixed-parameter systems; R5F100GJGFA#V0 maintains identical functionality but shifts to a more widely supported 0.65 mm pitch footprint, easing manufacturing scalability at the expense of slightly larger board area.
