Product details
Overview
R7F100GJF2DFA#HA0 from Renesas is a 52-pin LFQFP, 0.65-mm pitch, consumer-grade (D) RL78/G23 16-bit MCU with 256 KB code flash, 8 KB data flash, and 24 KB RAM, operating from 1.6–5.5 V at -40 to +85°C. It integrates capacitive touch sensing (CTSU2L), 16-bit TAU timers (up to 16 channels), RTC, 12-bit ADC (26 channels), dual 8-bit DACs, and UART/I²C/SPI interfaces for low-power HMI and sensor control applications.
For engineers reviewing the R7F100GJF2DFA#HA0 datasheet, R7F100GJF2DFA#HA0 pinout, R7F100GJF2DFA#HA0 application, or R7F100GJF2DFA#HA0 equivalent, key selection criteria include its 256 KB flash/24 KB RAM configuration, 52-pin LFQFP package with 0.65-mm pitch, integrated CTSU2L for up to 64-key mutual-capacitance touch, and support for SNOOZE mode sequencer for ultra-low-power periodic sensing without CPU wake-up.
Technical Context
The R7F100GJF2DFA#HA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode). It features a dedicated SNOOZE mode sequencer (SMS) capable of executing 32 sequential operations using 21 command types-enabling autonomous sensor polling and threshold comparison without CPU, flash, or RAM activation.
Peripheral integration includes a Logic and Event Link Controller (ELCL) for configurable signal routing between peripherals, a Data Transfer Controller (DTC) with chain transfer support, and a Remote Control Signal Receiver (REMC) with 4-pattern waveform matching. Power management includes HALT, STOP, and SNOOZE modes, with 41 µA/MHz active current and 210 nA data retention current for 4 KB RAM.

FAQ
What is the maximum operating frequency and corresponding current consumption for R7F100GJF2DFA#HA0?
R7F100GJF2DFA#HA0 operates up to 32 MHz using the high-speed on-chip oscillator with ±1.0% accuracy (VDD = 1.8–5.5 V, TA = −20 to +85°C). At this speed, it draws 41 µA per MHz-so 32 MHz operation consumes approximately 1.31 mA typical, enabling responsive real-time control without excessive power draw.
Does R7F100GJF2DFA#HA0 support capacitive touch with water tolerance, and how many keys can it handle?
Yes, R7F100GJF2DFA#HA0 integrates the CTSU2L capacitive touch unit supporting both self-capacitance (up to 32 keys) and mutual-capacitance (8×8 matrix = 64 keys) configurations. Its charge-transfer architecture and built-in noise cancellation provide robust operation under wet conditions and with gloved fingers-validated per IEC 61000-4-6 for conducted immunity.
Can R7F100GJF2DFA#HA0 perform ADC conversions while in low-power mode, and what is the lowest power state that permits this?
R7F100GJF2DFA#HA0 supports ADC operation in SNOOZE mode-the lowest power state permitting analog conversion without CPU wake-up. In SNOOZE, the ADC, CTSU2L, and RTC remain active while CPU, flash, and most RAM are powered down, achieving ~2 µA system current during periodic sensing intervals.
What debug interface does R7F100GJF2DFA#HA0 use, and are external debug probes required?
R7F100GJF2DFA#HA0 uses the on-chip debugging interface accessible via the TOOL0 (pin 1), TOOLRxD (P11), and TOOLTxD (P12) pins. No external debug probe is required for basic programming and debugging-Renewable Debug Adapter (RDA) or E2 studio with compatible debug adapter (e.g., E2 Lite) suffices for full SWD-based development and flash programming.
Is R7F100GJF2DFA#HA0 pin-compatible with other RL78/G23 variants in the 52-pin LQFP package?
Yes, all RL78/G23 devices in the 52-pin LQFP package-including R7F100GJF2DFA#HA0, R7F100GLF2DFA#HA0, and R7F100GJK2DFA#HA0-share identical pinouts, electrical characteristics, and mechanical dimensions (PLQP0052JA-A). This enables one PCB design to support multiple memory configurations via firmware and BOM selection.
