Product details
Overview
R7F100GFG2DFP#HA0 from Renesas is an RL78/G23 16-bit MCU with 256 KB code flash, 8 KB data flash, and 24 KB RAM, operating at 1.6–5.5 V; features include 12-bit A/D converter (26 channels), capacitive touch sensing (up to 64 keys), real-time clock, and ultra-low-power STOP mode (210 nA data retention); used in battery-powered industrial HMI and sensor nodes.
For engineers reviewing the R7F100GFG2DFP#HA0 datasheet, R7F100GFG2DFP#HA0 pinout, R7F100GFG2DFP#HA0 application, or R7F100GFG2DFP#HA0 equivalent, key selection criteria include its 44-pin LQFP-0.8mm package, -40°C to +85°C industrial temperature grade, integrated CTSU2L for self/mutual capacitance sensing, and SNOOZE mode sequencer for autonomous low-power peripheral sequencing without CPU wake-up.
Technical Context
The R7F100GFG2DFP#HA0 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), and includes a dedicated SNOOZE mode sequencer (SMS) capable of executing 32 sequential commands across 21 instruction types-enabling autonomous analog monitoring, timer triggering, and I/O control while the CPU remains halted.
It integrates a Logic and Event Link Controller (ELCL) that routes event signals between peripherals (e.g., ADC completion → DMA trigger → UART transmit), plus a Data Transfer Controller (DTC) supporting chain transfer and block/normal/repeat modes activated by 128 interrupt sources-reducing CPU load during high-throughput data movement.

FAQ
What is the maximum operating frequency and corresponding instruction execution time for the R7F100GFG2DFP#HA0?
The R7F100GFG2DFP#HA0 operates at up to 32 MHz using the high-speed on-chip oscillator. At this frequency, the minimum instruction execution time is 0.03125 µs. The core also supports ultra-low-speed operation at 32.768 kHz (30.5 µs/instruction) for RTC and standby functions-both modes are selectable without external crystals.
Does the R7F100GFG2DFP#HA0 support hardware-based capacitive touch sensing, and how many keys can it handle?
Yes, the R7F100GFG2DFP#HA0 integrates the CTSU2L capacitive sensing unit. It supports self-capacitance mode for up to 32 independent keys using single-pin configuration, or mutual-capacitance mode in 8×8 matrix layout for up to 64 keys-both with built-in noise cancellation and automatic calibration, eliminating need for external components or firmware compensation.
What are the power supply requirements and low-power modes supported by the R7F100GFG2DFP#HA0?
The R7F100GFG2DFP#HA0 requires a single 1.6 V to 5.5 V supply, compatible with 1.8 V, 2.5 V, and 3.0 V logic domains. It supports HALT (core stop, peripherals active), STOP (peripherals halted, RAM retained at 210 nA), and SNOOZE modes. SNOOZE enables autonomous peripheral sequencing-including ADC sampling, comparison, and GPIO toggling-without CPU wake-up or flash access.
Can the R7F100GFG2DFP#HA0 perform simultaneous read and write operations on its flash memory?
No-the R7F100GFG2DFP#HA0 does not support concurrent read-while-write on code flash. However, it supports Background Operation (BGO) on its separate 8 KB data flash: instructions can be executed from code flash while data flash is being rewritten, enabling seamless parameter updates or logging without system interruption.
What communication interfaces are available on the R7F100GFG2DFP#HA0, and which support LIN bus protocol?
The R7F100GFG2DFP#HA0 provides up to 6 UART/UARTA channels, all of which support LIN bus protocol per ISO 17987-4. It also includes up to 10 I²C/Simplified I²C channels (with clock stretching), 8 CSI/SPI channels, and a remote control signal receiver (REMC) for NEC/RC5 protocols-making it suitable for automotive body electronics and industrial network gateways.
