Product details
Overview
R7F100GFJ2DFP#HA0 from Renesas is a 52-pin LFQFP, 0.65-mm pitch, industrial-grade (−40 to +85°C) RL78/G23 16-bit MCU with 256 KB code flash, 8 KB data flash, 24 KB RAM, 1.6–5.5 V operation, and integrated capacitive touch sensing unit. It delivers ultra-low power consumption (41 µA/MHz active, 210 nA data retention), supports SNOOZE mode for autonomous peripheral sequencing, and targets battery-powered HMI and sensor-edge applications.
For engineers reviewing the R7F100GFJ2DFP#HA0 datasheet, R7F100GFJ2DFP#HA0 pinout, R7F100GFJ2DFP#HA0 application, or R7F100GFJ2DFP#HA0 equivalent, key selection criteria include its 52-pin LFQFP-0.65mm package, 256 KB/24 KB memory configuration, CTSU2L capacitive sensing support, and dual-voltage I/O capability (1.8/2.5/3.0 V compatible).
Technical Context
The R7F100GFJ2DFP#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). Its SNOOZE mode sequencer (SMS) executes up to 32 autonomous processes using 21 command types without CPU, flash, or RAM activation.
Peripheral integration includes a Logic and Event Link Controller (ELCL) for configurable event routing between peripherals, a Data Transfer Controller (DTC) with chain transfer, and a Realtime Clock with alarm and correction-enabling deterministic low-power timing and sensor data handling in resource-constrained systems.

The R7F100GFJ2DFP#HA0 supports a maximum CPU clock 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 for RTC and deep-sleep functions, with corresponding 30.5 µs instruction time.
Does the R7F100GFJ2DFP#HA0 support in-circuit debugging?
Yes, the R7F100GFJ2DFP#HA0 includes on-chip debugging functionality via the TOOL0 and TOOLRxD/TOOLTxD pins. It supports full breakpoint, step-through, and memory inspection capabilities using Renesas E2 studio and E2 Lite debugger, with no external debug probe required beyond standard SWD/JTAG interface.
What capacitive touch configurations does the R7F100GFJ2DFP#HA0 support?
The R7F100GFJ2DFP#HA0 integrates the CTSU2L capacitive sensing unit supporting both self-capacitance (up to 32 keys on single pins) and mutual capacitance (up to 64 keys in 8×8 matrix) modes. It operates across the full 1.8–5.5 V VDD range and includes hardware noise cancellation for robust operation in electrically noisy environments.
How many serial communication interfaces are available on the R7F100GFJ2DFP#HA0?
The R7F100GFJ2DFP#HA0 provides up to 6 UARTA channels (including LIN support), 10 I²C/Simplified I²C channels, and 8 CSI (SPI-compatible) channels. Pin multiplexing allows concurrent use of multiple interfaces-for example, I²C for OLED, UART for BLE, and CSI for SD card-all active simultaneously.
Is the R7F100GFJ2DFP#HA0 pin-compatible with other RL78/G23 variants?
No, the R7F100GFJ2DFP#HA0 is not pin-compatible with other RL78/G23 variants due to differing pin counts and package types. It uses a 52-pin LFQFP (0.65-mm pitch), whereas variants like R7F100GEJ2DNP#HA0 use 40-pin HWQFN and R7F100GLJ2DFA#AA0 use 64-pin LQFP-requiring distinct PCB layouts for each.
