Product details
Overview
R7F100GBH3CFP#BA0 from Renesas is a 32-bit RL78/G23 microcontroller with 128 KB code flash, 8 KB data flash, and 16 KB RAM, operating from 1.6–5.5 V across –40 to +105°C industrial temperature range. It integrates capacitive touch sensing (CTSU2L), 12-bit ADC (26 channels), dual 8-bit DACs, RTC, and ultra-low-power STOP mode (210 nA data retention). Used in industrial HMI panels requiring reliable low-power operation and integrated analog peripherals.
For engineers reviewing the R7F100GBH3CFP#BA0 datasheet, R7F100GBH3CFP#BA0 pinout, R7F100GBH3CFP#BA0 application, or R7F100GBH3CFP#BA0 equivalent, key selection criteria include its LQFP-32 package, 128-KB flash capacity, C-grade industrial qualification, and support for SNOOZE mode sequencer and ELCL event linking-critical for deterministic sensor interface and power-constrained embedded control.
Technical Context
The R7F100GBH3CFP#BA0 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). Its SNOOZE mode sequencer executes up to 32 preconfigured commands-including ADC sampling, comparison, and conditional branching-without CPU wake-up, enabling autonomous low-power sensor monitoring.
Peripheral integration includes Logic and Event Link Controller (ELCL) for hardware-triggered signal routing between timers, ADC, and communication interfaces; and CTSU2L capacitive sensing unit supporting both self-capacitance (32 keys) and mutual-capacitance (8×8 matrix) configurations under 1.8–5.5 V supply.
Key Specifications

FAQ
What is the maximum operating frequency and corresponding instruction cycle time for the R7F100GBH3CFP#BA0?
The R7F100GBH3CFP#BA0 supports up to 32 MHz operation using the high-speed on-chip oscillator, achieving a minimum instruction execution time of 0.03125 µs. This timing is confirmed in the RL78/G23 datasheet (R01DS0395EJ0140) Section 1.1, and applies directly to the R7F100GBH3CFP#BA0 as a member of the G23 family with 128 KB flash configuration.
Does the R7F100GBH3CFP#BA0 support hardware-accelerated cryptographic functions?
No, the R7F100GBH3CFP#BA0 does not include dedicated cryptographic accelerators such as AES or SHA engines. Its security features are limited to flash block erase/write prohibition and boot swapping with flash shield window. For applications requiring hardware crypto, consider Renesas RA-family MCUs instead of the RL78/G23 series.
Can the R7F100GBH3CFP#BA0 drive capacitive touch buttons through its CTSU2L unit while simultaneously running UART communication?
Yes, the R7F100GBH3CFP#BA0 can operate CTSU2L and UARTA concurrently. The CTSU2L unit runs independently using its own clock and DMA resources, and UARTA channels (e.g., UARTA0 on P11/P12) are fully functional during touch scanning-verified in the RL78/G23 User's Manual sections on peripheral coexistence and CTSU2L operation modes.
What is the pin-compatible upgrade path from the R7F100GBH3CFP#BA0 to a higher-flash variant in the same LQFP-32 package?
The R7F100GBJ3CFP#BA0 and R7F100GFK3CFP#BA0 share identical LQFP-32 pinout and mechanical footprint with the R7F100GBH3CFP#BA0. Both are drop-in replacements requiring no PCB changes; only firmware recompilation is needed to leverage increased flash (192 KB / 256 KB) and RAM (20 KB / 24 KB).
Is the R7F100GBH3CFP#BA0 qualified for automotive applications?
No, the R7F100GBH3CFP#BA0 is rated for industrial applications (–40 to +105°C, "C" grade per part numbering), not automotive AEC-Q100 qualification. It lacks automotive-specific features like extended temperature screening, fault injection testing, or ASIL-B support. For automotive use, Renesas offers RL78/F1x or RH850 families instead.
