Product details
Overview
R7F100GPH3CFB#BA0 from Renesas is a 100-pin LFQFP, 5.0-V tolerant, industrial-grade RL78/G23 16-bit MCU with 256 KB code flash, 8 KB data flash, and 24 KB RAM. It delivers ultra-low power operation (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (CTSU2L), and dual-clock domain support for real-time control in battery-powered HMI and sensor interface applications.
For engineers reviewing the R7F100GPH3CFB#BA0 datasheet, R7F100GPH3CFB#BA0 pinout, R7F100GPH3CFB#BA0 application, or R7F100GPH3CFB#BA0 equivalent, key selection criteria include its 100-pin LFQFP-0.5mm package, -40°C to +105°C industrial temperature rating, 256 KB flash/24 KB RAM memory configuration, and integrated CTSU2L capacitive sensing unit supporting up to 64 keys in mutual-capacitance mode.
Technical Context
The R7F100GPH3CFB#BA0 implements the RL78 CPU core with a 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). Its SNOOZE mode sequencer enables autonomous low-power peripheral sequencing without CPU wake-up, while the Event Link Controller (ELCL) allows hardware-level event chaining between peripherals such as timers, ADC, and UART.
It integrates a 12-bit A/D converter with up to 26 input channels, two 8-bit D/A outputs, two comparators with selectable internal/external reference, and a real-time clock with alarm and correction functions - all operating across the full 1.6–5.5 V supply range and industrial temperature grade.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GPH3CFB#BA0?
The R7F100GPH3CFB#BA0 supports up to 32 MHz operation with the high-speed on-chip oscillator, guaranteed across the full 1.6–5.5 V supply range. At 32 MHz, typical active current is 41 µA/MHz (1.31 mA total), and the ±1.0% oscillator accuracy is specified for VDD = 1.8–5.5 V and TA = –20 to +85°C - making the R7F100GPH3CFB#BA0 suitable for both battery-powered and industrial rail applications.
Does the R7F100GPH3CFB#BA0 support hardware-based capacitive touch sensing without external components?
Yes, the R7F100GPH3CFB#BA0 integrates the CTSU2L (Capacitive Touch Sensing Unit Level 2), which provides fully hardware-accelerated self- and mutual-capacitance measurement. It requires only external electrodes (PCB traces) and no external RC networks or dedicated touch ICs. The unit supports automatic noise cancellation, baseline tracking, and up to 64 keys in 8×8 mutual-capacitance mode - all managed by dedicated hardware independent of the CPU.
How many serial communication interfaces does the R7F100GPH3CFB#BA0 provide, and what protocols are supported?
The R7F100GPH3CFB#BA0 provides up to 6 UARTA channels (with LIN-bus support), 10 I²C/Simplified I²C channels, and 8 Simplified SPI (CSI) channels - configurable across its 100-pin package. All interfaces support multi-master arbitration, clock stretching, and programmable baud rates. UARTA includes automatic LIN header detection and checksum generation, while I²C supports standard (100 kHz) and fast (400 kHz) modes with internal pull-ups enabled.
What debug and programming interfaces are available on the R7F100GPH3CFB#BA0?
The R7F100GPH3CFB#BA0 supports on-chip debugging via the single-wire SWD (Serial Wire Debug) interface using pins P10 (SWCLK) and P11 (SWDIO), compatible with Renesas E2 studio and third-party JTAG/SWD debuggers. It also supports self-programming of code and data flash via the on-chip bootloader, enabling field firmware updates without external programmers. No external debug header is required - debug access uses standard GPIO pins with minimal PCB footprint.
Is the R7F100GPH3CFB#BA0 pin-compatible with other RL78/G23 variants in the same 100-pin LFQFP package?
Yes, all RL78/G23 devices in the 100-pin LFQFP package (e.g., R7F100GPG3CFB#BA0, R7F100GPH3CFB#BA0, R7F100GPJ3CFB#BA0) share identical pinouts, electrical characteristics, and peripheral mappings. Memory size differences (96–768 KB flash) and minor feature subsets (e.g., number of CTSU channels) do not affect pin function allocation - enabling drop-in replacement during design iteration or volume cost optimization without PCB changes.
