Product details
Overview
R7F100GBH3CNP#AA0 from Renesas is a 32-pin RL78/G23 16-bit microcontroller designed for ultra-low-power industrial applications, featuring 128 KB code flash, 16 KB RAM, 8 KB data flash, 1.6–5.5 V operation, and -40 to +105°C temperature range. It integrates capacitive touch sensing (CTSU2L), 16-bit TAU timers, RTC, UARTA/IICA/SAU interfaces, and SNOOZE mode sequencer for autonomous low-power sensor monitoring.
For engineers reviewing the R7F100GBH3CNP#AA0 datasheet, R7F100GBH3CNP#AA0 pinout, R7F100GBH3CNP#AA0 application, or R7F100GBH3CNP#AA0 equivalent, key selection criteria include its HWQFN-32 package with 0.5-mm pitch, 32.768-kHz RTC accuracy, 210-nA data retention current, and support for self-programming with flash shield window in industrial-grade thermal and voltage environments.
Technical Context
The R7F100GBH3CNP#AA0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). Its power management includes HALT, STOP, and SNOOZE modes-where the SNOOZE mode sequencer executes up to 32 preconfigured commands without CPU, flash, or RAM activation.
Peripheral integration includes a 21-command SNOOZE sequencer, ELCL for event-driven logic routing between peripherals, CTSU2L for self/mutual capacitance touch (up to 64 keys), and dual-voltage I/O supporting 1.8/2.5/3.0 V interface levels. All analog functions-10-bit ADC (26 channels), 8-bit DAC (2 channels), and 2-channel comparator-operate within the same 1.6–5.5 V supply domain.

FAQ
What is the maximum operating frequency and corresponding current consumption of the R7F100GBH3CNP#AA0?
The R7F100GBH3CNP#AA0 operates up to 32 MHz using its high-speed on-chip oscillator (±1.0% accuracy). At this frequency and VDD = 3.3 V, typical active current is 41 µA/MHz - resulting in ~1.3 mA total. This value is measured under defined test conditions in the R01DS0395EJ0140 datasheet Section 22.3.
Does the R7F100GBH3CNP#AA0 support in-system programming and secure firmware updates?
Yes, the R7F100GBH3CNP#AA0 supports self-programming with boot swapping and flash shield window protection. The 8 KB data flash allows background operation (BGO), enabling concurrent code execution and parameter updates. Security features include block erase prohibition and flash shield window to prevent unauthorized readout of protected regions.
What touch sensing capabilities does the R7F100GBH3CNP#AA0 provide, and how many electrodes can it drive?
The R7F100GBH3CNP#AA0 integrates the CTSU2L capacitive sensing unit supporting both self-capacitance (up to 32 single-pin keys) and mutual capacitance (8×8 matrix = 64 keys). It operates across the full 1.8–5.5 V supply range and includes hardware noise cancellation, eliminating need for external touch controllers in most HMI designs.
Is the R7F100GBH3CNP#AA0 pin-compatible with other RL78/G23 variants in the same package?
Yes, all RL78/G23 devices in the HWQFN-32 package-including R7F100GBF3CNP#AA0, R7F100GBG3CNP#AA0, R7F100GBH3CNP#AA0, and R7F100GBJ3CNP#AA0-share identical pinouts and electrical characteristics. Memory and peripheral configurations differ, but PCB layout and signal routing remain fully interchangeable.
What are the supported clock sources and their accuracy specifications for the R7F100GBH3CNP#AA0?
The R7F100GBH3CNP#AA0 supports three on-chip oscillators: high-speed (1–32 MHz, ±1.0% at VDD = 1.8–5.5 V, TA = –20 to +85°C), middle-speed (1–4 MHz, adjustable), and low-speed (32.768 kHz, adjustable). External crystals (X1/X2) are supported for RTC-grade accuracy, and EXCLK input allows synchronization to external timing sources.
