Product details
Overview
R7F100GJG2DFA#HA0 from Renesas is a 52-pin, consumer-grade 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. 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 8-bit DACs, RTC, and multiple serial interfaces including UARTA (up to 6 channels), IICA (up to 10 channels), and CSI (up to 8 channels) - deployed in battery-powered home appliance control panels.
For engineers reviewing the R7F100GJG2DFA#HA0 datasheet, R7F100GJG2DFA#HA0 pinout, R7F100GJG2DFA#HA0 application, or R7F100GJG2DFA#HA0 equivalent, key selection criteria include its 52-pin LQFP-0.65mm package, -40°C to +85°C temperature grade, SNOOZE mode sequencer for autonomous low-power sensor polling, and hardware ELCL for event-driven peripheral coordination without CPU intervention.
Technical Context
The RL78/G23 core implements a CISC architecture with 3-stage pipeline and configurable instruction timing (0.03125 µs at 32 MHz high-speed mode; 30.5 µs at 32.768 kHz ultra-low-speed mode). It supports multiply/divide/accumulate instructions and features a 1 MB address space with four banks of 8×8-bit general-purpose registers.
Power management includes HALT, STOP, and SNOOZE modes - the latter enabled by a dedicated sequencer executing up to 32 preconfigured commands (e.g., ADC sampling, comparison, GPIO toggle) without waking the CPU, flash, or RAM. The ELCL allows programmable logic-level event routing between peripherals (e.g., timer overflow → ADC trigger → interrupt), reducing software overhead.

FAQ
What is the maximum operating frequency and voltage range supported by the R7F100GJG2DFA#HA0?
The R7F100GJG2DFA#HA0 operates at up to 32 MHz using its high-speed on-chip oscillator (±1.0% accuracy) across a supply voltage range of 1.6 V to 5.5 V. This wide voltage window allows direct integration with single-cell Li-ion (2.7–4.2 V), 3×AA alkaline (3.0–4.5 V), or regulated 3.3 V/5 V rails without external level-shifting or voltage translation.
Does the R7F100GJG2DFA#HA0 support hardware-accelerated capacitive touch sensing?
Yes, the R7F100GJG2DFA#HA0 integrates the CTSU2L (Capacitive Touch Sensing Unit Level 2) supporting both self-capacitance (up to 32 keys) and mutual-capacitance (8×8 matrix, up to 64 keys) with built-in noise cancellation and auto-calibration. It requires no external components beyond a single external capacitor on P30 (TSCAP), enabling robust touch interfaces on standard PCBs.
How many serial communication interfaces does the R7F100GJG2DFA#HA0 provide, and what protocols are supported?
The R7F100GJG2DFA#HA0 provides up to 6 UARTA channels (with LIN-bus support), up to 10 IICA channels (I²C-compatible), and up to 8 CSI channels (SPI-compatible). All are implemented in the Serial Array Unit (SAU) with independent clock sources, FIFO buffers, and hardware flow control - enabling concurrent multi-protocol communication (e.g., UART to BLE, I²C to sensor, SPI to display) without resource contention.
What low-power modes are available on the R7F100GJG2DFA#HA0, and how does SNOOZE mode differ from STOP mode?
The R7F100GJG2DFA#HA0 supports HALT, STOP, and SNOOZE modes. In STOP mode, the CPU, flash, and RAM halt while RTC and LVD remain active. In SNOOZE mode, a dedicated sequencer executes predefined peripheral tasks (e.g., ADC conversion → compare → GPIO toggle) autonomously - keeping CPU, flash, and RAM fully powered down. This achieves deeper average power savings than STOP for periodic sensor polling or UI scanning.
Is the R7F100GJG2DFA#HA0 pin-compatible with other RL78/G23 variants in the 52-pin LQFP package?
Yes, all RL78/G23 52-pin LQFP variants (e.g., R7F100GJF2DFA#HA0, R7F100GJH2DFA#HA0, R7F100GJK2DFA#HA0) share identical pinouts and electrical characteristics. Firmware and PCB layouts are interchangeable across memory variants - allowing design reuse and easy BOM optimization based on final firmware size requirements.
