Product details
Overview
R7F100GJF3CFA#AA0 from Renesas is a 52-pin LQFP-packaged RL78/G23 16-bit microcontroller with 256 KB code flash, 8 KB data flash, and 24 KB RAM, operating from 1.6–5.5 V across –40 to +105°C industrial temperature range. It integrates capacitive touch sensing (CTSU2L), 12-bit ADC (26 channels), dual 8-bit DACs, RTC, and low-power STOP/SNOOZE modes - deployed in industrial HMI panels requiring robust touch control and deterministic real-time response.
For engineers reviewing the R7F100GJF3CFA#AA0 datasheet, R7F100GJF3CFA#AA0 pinout, R7F100GJF3CFA#AA0 application, or R7F100GJF3CFA#AA0 equivalent, key selection criteria include its 52-pin LQFP-0.65mm package, 256 KB flash/24 KB RAM memory configuration, industrial-grade thermal rating (–40 to +105°C), CTSU2L capacitive sensing support, and SNOOZE mode sequencer for ultra-low-power sensor polling without CPU 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 - with STOP mode enabling sub-µA retention (210 nA for 4 KB RAM) and fast wakeup.
Peripheral integration centers on event-driven autonomy: the Event Link Controller (ELCL) routes signals between peripherals without CPU intervention; the SNOOZE Mode Sequencer (SMS) executes up to 32 preconfigured operations (e.g., ADC sampling → comparison → GPIO toggle) using 21 command types while keeping CPU, flash, and RAM powered down.

FAQ
What is the maximum operating frequency and voltage range supported by the R7F100GJF3CFA#AA0?
The R7F100GJF3CFA#AA0 operates at up to 32 MHz using its high-speed on-chip oscillator (±1.0% accuracy) and supports a wide supply voltage range of 1.6 V to 5.5 V. This enables direct interfacing with diverse power domains - including 1.8 V logic, 3.3 V sensors, and 5 V actuators - without external level-shifting circuitry, simplifying board design for mixed-voltage industrial systems.
Does the R7F100GJF3CFA#AA0 support hardware-accelerated capacitive touch sensing?
Yes, the R7F100GJF3CFA#AA0 integrates the CTSU2L (Capacitive Touch Sensing Unit Level 2), which provides hardware-accelerated self-capacitance (up to 32 keys) and mutual-capacitance (8×8 matrix, up to 64 keys) sensing. It includes built-in noise cancellation, auto-calibration, and scan result buffering - enabling robust touch performance in electrically noisy industrial environments without burdening the CPU.
How does the SNOOZE mode sequencer in the R7F100GJF3CFA#AA0 reduce system power consumption?
The SNOOZE mode sequencer in the R7F100GJF3CFA#AA0 executes up to 32 pre-programmed operations - such as ADC sampling, value comparison, and GPIO toggling - entirely autonomously, without waking the CPU, flash, or RAM. This allows the R7F100GJF3CFA#AA0 to maintain sensor monitoring or periodic housekeeping tasks at sub-µA average current, extending battery life in edge-node applications far beyond conventional sleep-mode approaches.
What communication interfaces are available on the R7F100GJF3CFA#AA0, and how many instances does it support?
The R7F100GJF3CFA#AA0 supports multiple serial interfaces: up to 10 I²C/Simplified I²C channels, 6 UART/UARTA (including LIN-bus support), and 8 Simplified SPI (CSI) channels. These are distributed across dedicated pins (e.g., P60/P61 for I²C, P10–P12 for UART0) and can be remapped via the Peripheral I/O Redirection Register (PIOR), enabling flexible routing to match PCB layout constraints without sacrificing functionality.
Is the R7F100GJF3CFA#AA0 pin-compatible with other RL78/G23 variants in the same package?
Yes, the R7F100GJF3CFA#AA0 is pin-compatible with all other RL78/G23 devices in the 52-pin LQFP-0.65mm package (e.g., R7F100GJK3CFA#AA0, R7F100GJL3CFA#AA0), sharing identical pin functions and electrical characteristics. This allows seamless migration between memory/configurations - for example, upgrading from 192 KB to 256 KB flash - without PCB redesign, provided the target variant's peripheral enablement matches the application's runtime requirements.
