Product details
Overview
R5F100GCGFB#V0 from Renesas is a 48-pin LFQFP-packaged RL78/G13 16-bit MCU with 128 KB flash, 8 KB data flash, 12 KB RAM, 32 MHz max CPU speed (41 DMIPS), and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode) for industrial control, sensor nodes, and battery-powered HMI systems.
For engineers reviewing the R5F100GCGFB#V0 datasheet, R5F100GCGFB#V0 pinout, R5F100GCGFB#V0 application, or R5F100GCGFB#V0 equivalent, key selection criteria include its industrial-grade temperature range (–40°C to +105°C), integrated RTC with calendar/alarm, 26-channel 10-bit ADC, dual SPI/I²C/UART interfaces, and hardware multiplier/divider for real-time signal processing.
Technical Context
The R5F100GCGFB#V0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). It integrates a 12-bit interval timer, real-time clock with calendar and clock correction, and watchdog timer with dedicated low-speed oscillator.
Power management includes HALT, STOP, and SNOOZE modes, on-chip POR and LVD with 14 selectable voltage levels, and DMA controller with 4 channels enabling 2-clock transfers between SFR and RAM. The device supports background operation during data flash rewriting (BGO) and self-programming with boot swap and flash shield window functions.

FAQ
What is the operating temperature range of the R5F100GCGFB#V0?
The R5F100GCGFB#V0 is rated for industrial operation from –40°C to +105°C, confirmed by its 'G' suffix in the part number per Renesas RL78/G13 ordering guide. This specification applies across all operating modes including active, HALT, STOP, and SNOOZE, and is validated with the on-chip LVD and RTC functional across the full range.
Does the R5F100GCGFB#V0 include an integrated temperature sensor?
Yes, the R5F100GCGFB#V0 includes an on-chip temperature sensor usable with the 10-bit ADC. As specified in the RL78/G13 datasheet (R01DS0131EJ0380), this sensor is accessible via ANI channel and can be selected only in HS (high-speed main) mode - it provides calibrated output referenced to the internal 1.45 V bandgap voltage.
Can the R5F100GCGFB#V0 execute code while rewriting data flash memory?
Yes, the R5F100GCGFB#V0 supports Background Operation (BGO) for data flash. When enabled, the CPU can execute instructions from program memory while the data flash (8 KB) is being rewritten - a critical feature for firmware-over-the-air updates and real-time data logging without system interruption.
What communication interfaces are available on the R5F100GCGFB#V0?
The R5F100GCGFB#V0 provides six CSI (SPI-compatible) channels, three UART/LIN channels (supporting LIN 2.2 protocol), and five I²C/Simplified I²C channels. All are independently configurable and share no fixed pin conflicts - enabling concurrent use of UART for diagnostics, I²C for sensor bus, and CSI for display or memory interface.
Is the R5F100GCGFB#V0 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 48-pin LFQFP package (FB suffix) share identical pinouts, including R5F100GCGFB#V0, R5F100GAGFB#V0, and R5F101GCGFB#V0. Pin functions are fully compatible across memory variants, allowing hardware reuse when migrating between configurations - verified in Renesas' RL78/G13 pin configuration diagrams (pages 13–212 of R01DS0131EJ0380).
