Product details
Overview
R7F100GGH3CNP#HA0 from Renesas is a 48-pin LFQFP-packaged RL78/G23 16-bit microcontroller with 128 KB code flash, 8 KB data flash, and 16 KB RAM, operating from 1.6–5.5 V at -40 to +105°C. 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).
For engineers reviewing the R7F100GGH3CNP#HA0 datasheet, R7F100GGH3CNP#HA0 pinout, R7F100GGH3CNP#HA0 application, or R7F100GGH3CNP#HA0 equivalent, this MCU is selected for industrial HMI, battery-powered sensor nodes, and low-power control systems requiring integrated analog peripherals and robust capacitive touch support.
Technical Context
The RL78/G23 core features a 3-stage CISC pipeline with configurable instruction timing (0.03125 µs min @ 32 MHz high-speed oscillator or 30.5 µs @ 32.768 kHz subsystem clock). It supports SNOOZE mode sequencer (SMS) for autonomous low-power peripheral sequencing without CPU wake-up.
Peripheral integration includes Logic & Event Link Controller (ELCL) for hardware-triggered signal routing, Data Transfer Controller (DTC) with chain transfer, and background operation (BGO) for concurrent data flash rewriting while executing code from program memory.

FAQ
What is the maximum operating frequency and voltage range supported by the R7F100GGH3CNP#HA0?
The R7F100GGH3CNP#HA0 operates at up to 32 MHz using its high-speed on-chip oscillator and supports a single-supply voltage range of 1.6 V to 5.5 V. Its ±1.0% oscillator accuracy over -20 to +85°C eliminates need for external crystals in many applications, and the wide voltage range enables direct battery operation (e.g., 3× AA or LiSOCl₂ cells) without regulators.
Does the R7F100GGH3CNP#HA0 support capacitive touch sensing, and how many keys can it handle?
Yes, the R7F100GGH3CNP#HA0 integrates the CTSU2L capacitive touch sensing unit. It supports up to 32 self-capacitance keys (one per dedicated pin) or up to 64 mutual-capacitance keys in an 8×8 matrix configuration. The unit operates independently of the CPU in STOP or SNOOZE mode, enabling ultra-low-power touch wake-up functionality.
What are the flash memory specifications for the R7F100GGH3CNP#HA0, including data flash endurance?
The R7F100GGH3CNP#HA0 includes 128 KB of code flash memory and 8 KB of data flash memory. The data flash supports background operation (BGO), allowing code execution during rewrites. Its endurance is rated at 1,000,000 write/erase cycles (typical), making it suitable for logging, calibration storage, and field firmware updates without premature wear-out.
Can the R7F100GGH3CNP#HA0 operate in ultra-low-power modes, and what is the lowest current consumption?
Yes, the R7F100GGH3CNP#HA0 supports multiple low-power modes. In STOP mode with 4 KB of RAM retained, it draws just 210 nA (typical). HALT mode consumes 41 µA/MHz during active operation. These values are measured at VDD = 3.0 V and TA = 25°C, and enable multi-year operation on coin-cell batteries in sensor and remote monitoring applications.
What communication interfaces are available on the R7F100GGH3CNP#HA0, and how many instances of each are supported?
The R7F100GGH3CNP#HA0 provides up to 6 UARTA channels (including LIN support), 10 IICA (I²C-compatible) channels, and 8 CSI (SPI-compatible) channels. Specific instance counts depend on pin assignment and multiplexing - for example, P10–P12 support one SAU-based UARTA, while P60/P61 provide dedicated IICA0. All interfaces are accessible via the 48-pin LFQFP package's configurable I/O pins.
