Product details
Overview
R7F100GLJ2DFA#BA0 from Renesas is an RL78/G23 64-pin, 256-KB flash, 24-KB RAM ultra-low-power 16-bit MCU operating from 1.6 to 5.5 V, featuring 16-bit TAU timers (12 channels), 12-bit ADC (24 channels), capacitive touch sensing (CTSU2L), and UART/I²C/SPI interfaces - deployed in battery-powered industrial HMI and sensor node control.
For engineers reviewing the R7F100GLJ2DFA#BA0 datasheet, R7F100GLJ2DFA#BA0 pinout, R7F100GLJ2DFA#BA0 application, or R7F100GLJ2DFA#BA0 equivalent, key selection criteria include STOP-mode wakeup time (<3.5 µs), 210-nA data retention current, CTSU2L self/mutual capacitance support, and LQFP-64 0.65-mm pitch package compatibility with industrial temperature range (-40 to +85°C).
Technical Context
The R7F100GLJ2DFA#BA0 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz), and integrates a SNOOZE mode sequencer (SMS) enabling autonomous low-power peripheral sequencing without CPU wake-up. It includes dual voltage detectors (LVD0/LVD1), on-chip high-accuracy ±1.0% oscillator (32 MHz), and background data flash rewriting (BGO) with 1M-cycle endurance.
Peripheral integration includes ELCL for event-driven logic routing between functions, DTC for interrupt-triggered memory transfers, and RTC with alarm/correction - all optimized for deterministic real-time operation in resource-constrained embedded systems requiring <41 µA/MHz active current and sub-µA sleep states.

The R7F100GLJ2DFA#BA0 operates at up to 32 MHz using its high-speed on-chip oscillator, achieving a typical active current of 41 µA per MHz. At full speed, this yields ~1.3 mA total active current, verified under VDD = 3.3 V and TA = 25°C conditions per the R01DS0395EJ0140 datasheet.
Does the R7F100GLJ2DFA#BA0 support hardware-based capacitive touch sensing, and what configurations are available?
Yes, the R7F100GLJ2DFA#BA0 integrates the CTSU2L capacitive touch sensing unit supporting both self-capacitance (up to 32 keys on single pins) and mutual capacitance (8×8 matrix, up to 64 keys). It operates across the full VDD range (1.8–5.5 V) and requires no external components beyond standard decoupling capacitors.
Can the R7F100GLJ2DFA#BA0 perform flash memory writes while executing code from flash?
Yes, the R7F100GLJ2DFA#BA0 supports Background Operation (BGO) for data flash memory, allowing instruction execution from code flash while simultaneously rewriting data flash. This enables seamless firmware updates and parameter storage without halting real-time tasks.
What is the wakeup time from STOP mode for the R7F100GLJ2DFA#BA0, and which sources can trigger wake-up?
The R7F100GLJ2DFA#BA0 wakes from STOP mode in less than 3.5 µs when triggered by external interrupts (e.g., INTP0–INTP5), RTC alarm, or peripheral events routed via ELCL. This fast wakeup preserves real-time responsiveness in duty-cycled sensor applications.
Is the R7F100GLJ2DFA#BA0 pin-compatible with other RL78/G23 variants in the same 64-pin LQFP package?
Yes, all RL78/G23 64-pin LQFP variants - including R7F100GLJ2DFA#BA0, R7F100GLK2DFA#BA0, and R7F100GLH2DFA#BA0 - share identical pinouts and electrical characteristics. Memory and peripheral differences do not affect PCB layout, enabling scalable design reuse.
