Product details
Overview
R7F100GMJ2DFA#BA0 from Renesas is an RL78/G23 80-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 integrated UART/I²C/SPI interfaces - deployed in battery-powered industrial HMI and sensor node control.
For engineers reviewing the R7F100GMJ2DFA#BA0 datasheet, R7F100GMJ2DFA#BA0 pinout, R7F100GMJ2DFA#BA0 application, or R7F100GMJ2DFA#BA0 equivalent, key selection criteria include STOP-mode wakeup latency, CTSU2L key count scalability, data flash rewrite endurance (1M cycles), and 80-pin LQFP package compatibility with industrial temperature range (−40°C to +85°C).
Technical Context
The R7F100GMJ2DFA#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 embeds dual voltage detectors (LVD0/LVD1), a 32-bit interval timer, real-time clock with alarm and correction, and a logic/event link controller (ELCL) for configurable signal routing between peripherals - all optimized for deterministic response in resource-constrained embedded systems.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GMJ2DFA#BA0?
The R7F100GMJ2DFA#BA0 operates at up to 32 MHz using the high-speed on-chip oscillator, with guaranteed functionality across its full 1.6 V to 5.5 V supply range. At 32 MHz, minimum VDD is 2.7 V per datasheet timing specifications; lower frequencies (e.g., 16 MHz) are supported down to 1.6 V.
Does the R7F100GMJ2DFA#BA0 support hardware-based capacitive touch with noise immunity?
Yes, the R7F100GMJ2DFA#BA0 integrates the CTSU2L unit with built-in spread-spectrum modulation, shield driver, and digital filtering - enabling reliable touch detection in noisy industrial environments. It supports both self-capacitance (32 keys) and mutual-capacitance (64 keys) configurations without external components.
Can the R7F100GMJ2DFA#BA0 perform flash programming while executing code from another memory region?
Yes, the R7F100GMJ2DFA#BA0 supports background operation (BGO) for its 8 KB data flash. Code execution continues from code flash or RAM while data flash is rewritten - critical for field-upgradable firmware that logs calibration data or stores configuration without halting real-time tasks.
What debug interfaces are available on the R7F100GMJ2DFA#BA0, and are they accessible in production?
The R7F100GMJ2DFA#BA0 supports on-chip debugging via the dedicated TOOL0/TOOLRxD/TOOLTxD pins (SWD-compatible serial wire debug). Debug access remains enabled in production unless disabled via security fuse; the same pins can be repurposed as GPIO after programming if debug is no longer required.
How many independent UART, I²C, and SPI interfaces does the R7F100GMJ2DFA#BA0 provide?
The R7F100GMJ2DFA#BA0 provides three UARTA modules (supporting LIN-bus), four IICA modules (I²C), and three CSI modules (SPI-compatible). All are independently configurable with separate clock sources, interrupts, and DMA triggers - enabling simultaneous communication with multiple sensors, displays, and host controllers.
