Product details
Overview
R7F100GJJ2DFA#AA0 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 true low-power operation (41 µA/MHz active, 210 nA data retention), integrates capacitive touch sensing (up to 64 keys), and supports UART, I²C, SPI, RTC, and 12-bit ADC for battery-powered HMI and sensor interface applications.
For engineers reviewing the R7F100GJJ2DFA#AA0 datasheet, R7F100GJJ2DFA#AA0 pinout, R7F100GJJ2DFA#AA0 application, or R7F100GJJ2DFA#AA0 equivalent, key selection criteria include its 52-pin LQFP-0.65mm package, -40°C to +85°C temperature grade, integrated SNOOZE mode sequencer for autonomous low-power sensing, and hardware ELCL for event-driven peripheral coordination without CPU intervention.
Technical Context
The R7F100GJJ2DFA#AA0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting configurable instruction timing from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). Its power management includes HALT, STOP, and SNOOZE modes, with wake-up from STOP in under 4 µs and SNOOZE sequencer execution independent of CPU, flash, or RAM.
Peripheral integration includes a 21-command SNOOZE mode sequencer handling up to 32 processes, Logic & Event Link Controller (ELCL) enabling direct signal routing between peripherals (e.g., timer output triggering ADC conversion), and CTSU2L capacitive sensing unit supporting both self- and mutual-capacitance configurations with built-in noise suppression.
Key Specifications

FAQ
What is the maximum operating frequency and corresponding current consumption of the R7F100GJJ2DFA#AA0?
The R7F100GJJ2DFA#AA0 operates up to 32 MHz using its high-speed on-chip oscillator with ±1.0% accuracy. At this frequency, it draws 41 µA per MHz in active mode, resulting in approximately 1.31 mA total current. This enables responsive real-time control while maintaining industry-leading efficiency among 16-bit MCUs.
Does the R7F100GJJ2DFA#AA0 support hardware-based capacitive touch sensing, and what configurations are available?
Yes, the R7F100GJJ2DFA#AA0 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). It includes hardware noise cancellation, automatic drift compensation, and programmable sensitivity-enabling robust touch interfaces without external components.
Can the R7F100GJJ2DFA#AA0 perform flash memory writes while executing code from flash?
Yes, the R7F100GJJ2DFA#AA0 supports background operation (BGO) for its 8 KB data flash memory. Code execution continues uninterrupted from program memory during data flash erase/write cycles, enabling reliable parameter storage, firmware updates, and data logging without system stalls or timing violations.
What peripheral offload capabilities does the R7F100GJJ2DFA#AA0 provide to reduce CPU utilization?
The R7F100GJJ2DFA#AA0 features two key offload engines: the SNOOZE mode sequencer executes up to 32-step sensing/processing sequences autonomously, and the Logic & Event Link Controller (ELCL) routes signals directly between peripherals (e.g., timer → ADC → DMA). Both operate independently of the CPU, significantly lowering active time and power consumption.
Is the R7F100GJJ2DFA#AA0 pin-compatible with other RL78/G23 variants in the same package?
Yes, all RL78/G23 devices in the 52-pin LQFP-0.65mm package-including R7F100GJJ2DFA#AA0, R7F100GLJ2DFA#AA0, and R7F100GMJ2DFA#AA0-share identical pinouts and electrical characteristics. This enables drop-in memory upgrades during design iteration or production without PCB changes.
