Product details
Overview
R7F100GFH3CFP#HA0 from Renesas is a 44-pin LQFP-packaged RL78/G23 16-bit MCU with 128 KB code flash, 8 KB data flash, and 16 KB RAM, operating from 1.6–5.5 V at -40 to +85°C. It delivers ultra-low power consumption (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (CTSU2L), 12-bit ADC (26 channels), dual DAC, RTC, and multiple serial interfaces including UART, I²C, and CSI for industrial control and sensor node applications.
For engineers reviewing the R7F100GFH3CFP#HA0 datasheet, R7F100GFH3CFP#HA0 pinout, R7F100GFH3CFP#HA0 application, or R7F100GFH3CFP#HA0 equivalent, key selection criteria include its 44-pin LQFP-0.8 mm pitch package, industrial temperature grade (C-field), 128 KB flash/16 KB RAM memory configuration, CTSU2L support for up to 64 keys in mutual-capacitance mode, and SNOOZE mode sequencer for autonomous low-power peripheral operation without CPU wake-up.
Technical Context
The RL78/G23 core implements a 3-stage pipeline CISC architecture with configurable instruction timing (0.03125 µs min @ 32 MHz high-speed clock or 30.5 µs @ 32.768 kHz subsystem clock). It integrates a dedicated SNOOZE mode sequencer (SMS) supporting 32 sequential commands across 21 instruction types to offload periodic sensing and comparison tasks from the CPU.
Peripheral integration includes a Logic and Event Link Controller (ELCL) enabling hardware-triggered signal routing between peripherals, a Data Transfer Controller (DTC) with chain transfer capability, and a capacitive sensing unit (CTSU2L) supporting both self- and mutual-capacitance methods-enabling robust touch HMI on a single chip without external components.
Key Specifications

FAQ
What is the maximum operating frequency and corresponding instruction timing for the R7F100GFH3CFP#HA0?
The R7F100GFH3CFP#HA0 supports a maximum CPU frequency of 32 MHz using the high-speed on-chip oscillator. At this speed, the minimum instruction execution time is 0.03125 µs. The device also supports ultra-low-speed operation at 32.768 kHz (subsystem clock), where the minimum instruction time is 30.5 µs-enabling flexible trade-offs between performance and power consumption.
Does the R7F100GFH3CFP#HA0 support hardware-accelerated capacitive touch sensing, and what configurations are available?
Yes, the R7F100GFH3CFP#HA0 integrates the CTSU2L capacitive sensing unit. It supports self-capacitance mode (up to 32 keys on single pins) and mutual-capacitance mode (8×8 matrix, up to 64 keys). Both modes operate within the 1.8–5.5 V supply range and include built-in noise cancellation features suitable for industrial environments with EMI.
What serial communication interfaces are available on the R7F100GFH3CFP#HA0, and how many channels does each support?
The R7F100GFH3CFP#HA0 provides UART/UARTA (up to 6 channels), I²C/Simplified I²C (up to 10 channels), and CSI (Simplified SPI, up to 8 channels). All interfaces are implemented in the Serial Array Unit (SAU) and Serial Interface (IICA, UARTA) modules, with full pin multiplexing flexibility across P10–P17 and other port groups.
How does the SNOOZE mode sequencer (SMS) in the R7F100GFH3CFP#HA0 reduce system power consumption?
The SNOOZE mode sequencer (SMS) in the R7F100GFH3CFP#HA0 executes up to 32 pre-programmed commands-including ADC conversions, register comparisons, and GPIO toggles-while the CPU, flash, and RAM remain powered down. This eliminates CPU wake-up overhead and enables autonomous sensor polling at intervals as short as milliseconds, reducing average system current to sub-microamp levels.
What is the data flash endurance and background operation capability of the R7F100GFH3CFP#HA0?
The R7F100GFH3CFP#HA0 includes 8 KB of data flash memory rated for 1,000,000 write/erase cycles (typical). It supports Background Operation (BGO), allowing the CPU to execute instructions from code flash while simultaneously rewriting data flash-enabling real-time parameter updates, firmware logging, and OTA staging without interrupting application execution.
