Product details
Overview
R7F100GFF3CFP#HA0 from Renesas is a 44-pin LQFP-packaged RL78/G23 16-bit microcontroller with 192 KB code flash, 8 KB data flash, and 20 KB RAM, operating from 1.6–5.5 V and rated for -40 to +85°C industrial use. It integrates capacitive touch sensing (up to 64 keys), 12-bit ADC (26 channels), dual 8-bit DACs, RTC, and multiple serial interfaces including UARTA, IICA, and CSI for embedded control in battery-powered and industrial HMI applications.
For engineers reviewing the R7F100GFF3CFP#HA0 datasheet, R7F100GFF3CFP#HA0 pinout, R7F100GFF3CFP#HA0 application, or R7F100GFF3CFP#HA0 equivalent, key selection criteria include its 44-pin LQFP-0.8 mm pitch package, 192 KB flash/20 KB RAM memory configuration, integrated CTSU2L capacitive sensing unit, ultra-low-power STOP/SNOOZE modes, and support for LIN-bus via UARTA.
Technical Context
The RL78/G23 core implements a 3-stage pipeline CISC architecture with configurable instruction timing (0.03125 µs at 32 MHz high-speed mode or 30.5 µs at 32.768 kHz ultra-low-speed mode) and supports multiply/divide/MAC instructions. Its SNOOZE mode sequencer executes up to 32 low-power background processes without CPU, flash, or RAM activation.
Peripheral integration includes an Event Link Controller (ELCL) enabling hardware-triggered signal routing between peripherals, a Data Transfer Controller (DTC) supporting chain transfers, and a Realtime Clock with alarm and clock correction-enabling autonomous timekeeping and event scheduling independent of CPU intervention.

What is the maximum operating frequency and corresponding supply voltage range for the R7F100GFF3CFP#HA0?
The R7F100GFF3CFP#HA0 operates at up to 32 MHz using the high-speed on-chip oscillator, supported across its full 1.6–5.5 V supply range. At 32 MHz, minimum instruction execution time is 0.03125 µs. The device also supports ultra-low-speed operation at 32.768 kHz for RTC and low-power monitoring, with the same voltage range.
Does the R7F100GFF3CFP#HA0 support LIN bus communication, and which peripheral implements it?
Yes, the R7F100GFF3CFP#HA0 supports LIN 2.2 bus communication via its UARTA peripheral. UARTA includes dedicated LIN frame formatting, auto-sync detection, and break signal generation-enabling direct connection to automotive body control modules without external transceivers.
How many capacitive touch channels does the R7F100GFF3CFP#HA0 support, and what configurations are available?
The R7F100GFF3CFP#HA0 supports up to 64 capacitive touch channels using its CTSU2L unit: 32 channels in self-capacitance mode (one pin per key) or 64 channels in 8×8 mutual-capacitance matrix mode. Both configurations operate within the 1.8–5.5 V VDD range and include built-in noise cancellation.
What are the flash memory organization and security features of the R7F100GFF3CFP#HA0?
The R7F100GFF3CFP#HA0 contains 192 KB of code flash organized in 2 KB blocks. Security features include prohibition of block erase and rewriting (flash shield window), on-chip debugging lock, and self-programming support with boot swapping-preventing unauthorized firmware modification and enabling secure field updates.
Can the R7F100GFF3CFP#HA0 perform ADC conversions while in STOP mode, and if not, what low-power alternative exists?
No, the R7F100GFF3CFP#HA0 cannot perform ADC conversions in STOP mode-the ADC is disabled. However, it supports SNOOZE mode, where the SNOOZE mode sequencer can autonomously trigger ADC sampling, process results, and assert interrupts-all without waking the CPU, flash, or RAM, achieving ultra-low-power periodic sensing.
