Product details
Overview
R7F100GPJ2DFA#BA0 from Renesas is a 100-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 (CTSU2L), RTC, 16-bit TAU timers, UARTA/IICA/SAU interfaces, and supports SNOOZE mode for autonomous peripheral sequencing.
For engineers reviewing the R7F100GPJ2DFA#BA0 datasheet, R7F100GPJ2DFA#BA0 pinout, R7F100GPJ2DFA#BA0 application, or R7F100GPJ2DFA#BA0 equivalent, key selection criteria include its 100-pin LFQFP package, -40 to +85°C temperature grade, 256 KB flash capacity, integrated CTSU2L for up to 64-key mutual-capacitance touch, and SNOOZE mode sequencer enabling CPU-off sensor polling and event-driven wake-up.
Technical Context
The RL78/G23 core implements a 3-stage pipeline CISC architecture with configurable instruction timing (0.03125 µs at 32 MHz high-speed mode; 30.5 µs at 32.768 kHz ultra-low-speed mode) and supports multiply/divide/MAC instructions. Its power management includes HALT, STOP, and SNOOZE modes - the latter using a dedicated sequencer to execute up to 32 preconfigured commands across 21 instruction types without CPU, flash, or RAM involvement.
Peripheral integration includes a Logic and Event Link Controller (ELCL) enabling hardware-level signal routing between peripherals, a Data Transfer Controller (DTC) supporting chain transfers, and a Remote Control Signal Receiver (REMC) with 4-pattern waveform matching. The CTSU2L unit operates in self- or mutual-capacitance mode, with VDD = 1.8–5.5 V support and up to 64-key matrix capability.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GLJ2DFA#BA0 | Same 100-pin LFQFP package and D-grade (-40 to +85°C), but with 512 KB flash and 48 KB RAM | Targeted at applications requiring larger firmware footprint (e.g., protocol stacks, GUI frameworks) or extended data logging buffers | Select when firmware size exceeds 256 KB or >24 KB RAM is needed for real-time analytics; no PCB change required |
| R7F100GPJ3CFA#AA0 | Identical flash/RAM (256 KB/24 KB) and pinout, but industrial-grade (C suffix, -40 to +105°C) and different packaging (#AA0 tray) | Required for operation in high-temperature environments (e.g., automotive cabin modules, industrial PLCs) | Choose for thermal robustness where ambient exceeds +85°C; same schematic/layout, only qualification and packaging differ |
Compared with R7F100GLJ2DFA#BA0, the R7F100GPJ2DFA#BA0 trades flash/RAM headroom for cost optimization in volume consumer designs; versus R7F100GPJ3CFA#AA0, it offers lower-temperature qualification suited for indoor electronics, reducing qualification overhead and BOM cost.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GPJ2DFA#BA0?
The R7F100GPJ2DFA#BA0 supports a maximum operating frequency of 32 MHz using the high-speed on-chip oscillator, with guaranteed operation across its full 1.6–5.5 V supply range. At 32 MHz, the minimum instruction execution time is 0.03125 µs. The device maintains functional operation down to 1.6 V, enabling direct use with single-cell Li-ion or alkaline battery sources without external regulation.
Does the R7F100GPJ2DFA#BA0 support hardware-accelerated capacitive touch sensing, and what configurations are available?
Yes, the R7F100GPJ2DFA#BA0 integrates the CTSU2L capacitive touch sensing unit supporting both self-capacitance (up to 32 keys on single pins) and mutual-capacitance (up to 64 keys in 8×8 matrix) configurations. It operates with VDD as the reference voltage (1.8–5.5 V), includes noise suppression features, and allows tuning of sensitivity and scan speed via register settings - all without CPU intervention during measurement.
How does the SNOOZE mode sequencer (SMS) in the R7F100GPJ2DFA#BA0 reduce system power consumption?
The SNOOZE mode sequencer in the R7F100GPJ2DFA#BA0 executes up to 32 preloaded commands (e.g., ADC conversion, value comparison, GPIO toggle) autonomously - without waking the CPU, accessing flash memory, or powering RAM. This enables periodic sensor polling or event-triggered responses at typical currents of 1.2 µA, significantly lowering average power in duty-cycled applications compared to CPU-based polling loops.
Can the R7F100GPJ2DFA#BA0 perform background data flash writes while executing application code from main flash memory?
Yes, the R7F100GPJ2DFA#BA0 supports Background Operation (BGO) for its 8 KB data flash memory. This allows the CPU to execute instructions from code flash while simultaneously erasing or programming data flash sectors - essential for reliable firmware updates, secure key storage, and real-time parameter logging without interrupting real-time tasks.
What debug and programming interfaces are supported by the R7F100GPJ2DFA#BA0, and are they accessible in the 100-pin LFQFP package?
The R7F100GPJ2DFA#BA0 supports on-chip debugging via the standard SWD interface using dedicated pins (TOOL0, TOOLRxD, TOOLTxD) - all routed to accessible pins in the 100-pin LFQFP package. These pins are multiplexed with UARTA functions but default to debug mode on reset, enabling full JTAG/SWD debugging, flash programming, and real-time trace without requiring additional headers or board space.
