Overview
R5F100GDGFB#V0 from Renesas is a 48-pin LFQFP-packaged RL78/G13 16-bit microcontroller with 128 KB flash, 8 KB data flash, 12 KB RAM, and integrated peripherals including 10-bit ADC (26 channels), RTC, UART, I²C, CSI, and 16-bit timers. It operates from 1.6–5.5 V and delivers 41 DMIPS at 32 MHz for low-power industrial control applications.
For engineers reviewing the R5F100GDGFB#V0 datasheet, R5F100GDGFB#V0 pinout, R5F100GDGFB#V0 application, or R5F100GDGFB#V0 equivalent, key selection criteria include its -40°C to +105°C industrial temperature grade (G), 0.57 μA STOP mode current, on-chip debug support, and compatibility with Renesas' RL78 toolchain and E2 studio IDE.
Technical Context
The R5F100GDGFB#V0 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 ultra-low-speed mode). Its memory subsystem includes 128 KB code flash with 1 KB block erase, 8 KB background-operable data flash (1M rewrite cycles), and 12 KB SRAM.
Peripherals are tightly integrated: dual DMA controller (4 channels), 16-bit timer array (16 channels), real-time clock with calendar/alarm, 10-bit ADC with internal 1.45 V reference and temperature sensor, and multiple serial interfaces (CSI, UART/LIN, I²C) - all configurable via dedicated SFRs and supported by hardware interrupt vectors.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100GDGFB#V0?
The R5F100GDGFB#V0 operates at up to 32 MHz, delivering 41 DMIPS of processing performance. This enables deterministic execution of real-time control algorithms such as motor FOC or sensor fusion within strict timing budgets. Its minimum instruction execution time is 0.03125 μs in high-speed mode, verified across the full -40°C to +105°C industrial temperature range.
Does the R5F100GDGFB#V0 include on-chip debug capability and what interfaces does it support?
Yes, the R5F100GDGFB#V0 integrates full on-chip debug functionality compatible with Renesas E2 emulator and E2 studio IDE. It supports SWD (Serial Wire Debug) via dedicated debug pins and enables non-intrusive breakpoints, real-time variable watch, and flash programming - all without requiring external debug hardware beyond the standard E2 probe.
How much data flash memory does the R5F100GDGFB#V0 have, and what is its endurance specification?
The R5F100GDGFB#V0 includes 8 KB of on-chip data flash memory rated for 1,000,000 write/erase cycles (typical) at VDD = 1.8–5.5 V. It supports background operation (BGO), allowing application code to execute from main flash while data flash is being rewritten - essential for reliable over-the-air parameter updates in deployed R5F100GDGFB#V0 systems.
What are the low-power consumption modes supported by the R5F100GDGFB#V0 and their typical current draw?
The R5F100GDGFB#V0 supports HALT (66 μA/MHz), STOP (0.57 μA with RTC + LVD active), and SNOOZE modes. In STOP mode, only the 32.768 kHz sub-system clock and LVD remain active - enabling decade-long operation on coin-cell batteries in metering or sensor node applications using the R5F100GDGFB#V0.
Is the R5F100GDGFB#V0 qualified for automotive applications, and what temperature grade does it carry?
The R5F100GDGFB#V0 carries the 'G' suffix denoting Industrial temperature grade (-40°C to +105°C), qualified per AEC-Q100 stress test requirements for automotive body electronics. While not marketed as an automotive-grade MCU, its extended temperature range and built-in LVD with 14-level detection make it suitable for under-hood BCU, HVAC, and lighting modules where ASIL-B diagnostics are implemented in software.
