Product details
Overview
R7F100GGF3CNP#AA0 from Renesas is an RL78/G23 48-pin HWQFN microcontroller with 128 KB code flash, 8 KB data flash, and 16 KB RAM, operating from 1.6–5.5 V. It delivers ultra-low power consumption (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (CTSU2L), 16-bit TAU timers, RTC, and dual UART/I²C/SPI interfaces - deployed in industrial human-machine interface modules requiring robust low-power operation.
For engineers reviewing the R7F100GGF3CNP#AA0 datasheet, R7F100GGF3CNP#AA0 pinout, R7F100GGF3CNP#AA0 application, or R7F100GGF3CNP#AA0 equivalent, key selection criteria include its 48-pin HWQFN-0.5mm package, -40°C to +105°C industrial temperature grade, CTSU2L capacitive sensing support, SNOOZE mode sequencer for autonomous low-power event handling, and hardware-based ELCL logic linking peripheral events without CPU intervention.
Technical Context
The R7F100GGF3CNP#AA0 implements the RL78 CPU core with a 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode). Its on-chip oscillators include selectable high-speed (1–32 MHz ±1.0%), middle-speed (1–4 MHz), and low-speed (32.768 kHz) sources, enabling precise clock domain partitioning across system peripherals.
Power management includes HALT, STOP, and SNOOZE modes - the latter driven by a dedicated sequencer executing up to 32 configurable commands (e.g., ADC sampling, comparison, register write) without waking the CPU or accessing flash/RAM. Peripheral event routing is handled by the ELCL, which supports combinational logic and flip-flop operations between 21 configurable event sources.

FAQ
What is the maximum operating frequency and voltage range supported by the R7F100GGF3CNP#AA0?
The R7F100GGF3CNP#AA0 operates at up to 32 MHz using its high-speed on-chip oscillator with ±1.0% accuracy across 1.8–5.5 V, and supports a full 1.6–5.5 V supply range. At 32 MHz, minimum instruction execution time is 0.03125 µs; at 32.768 kHz, it extends to 30.5 µs for ultra-low-power operation. The device maintains full functionality across its entire voltage and temperature range (-40°C to +105°C).
Does the R7F100GGF3CNP#AA0 support capacitive touch sensing, and how many keys can it handle?
Yes, the R7F100GGF3CNP#AA0 integrates the CTSU2L capacitive sensing unit supporting both self-capacitance (up to 32 independent keys) and mutual-capacitance (8×8 matrix, up to 64 keys). It operates under VDD = 1.8–5.5 V, includes built-in noise cancellation, and requires no external components - enabling robust touch interfaces in industrial environments with EMI exposure.
What low-power modes are available on the R7F100GGF3CNP#AA0, and what is the lowest current draw?
The R7F100GGF3CNP#AA0 supports HALT, STOP, and SNOOZE modes. In STOP mode with 4 KB of RAM retained, it draws just 210 nA - verified at VDD = 3.0 V and TA = 25°C. SNOOZE mode enables autonomous peripheral operation (e.g., ADC sampling, comparisons) without CPU, flash, or RAM activation, achieving sub-µA average current in sensor-monitoring applications.
Can the R7F100GGF3CNP#AA0 perform background data flash writes while executing application code?
Yes, the R7F100GGF3CNP#AA0 supports Background Operation (BGO) for its 8 KB data flash memory. This allows the CPU to execute instructions from code flash while simultaneously rewriting data flash - essential for reliable firmware updates, parameter logging, and over-the-air configuration changes without system interruption or data loss.
What communication interfaces are integrated into the R7F100GGF3CNP#AA0, and how many instances does each support?
The R7F100GGF3CNP#AA0 integrates multiple serial interfaces: up to 10 I²C/Simplified I²C channels, 6 UART/UARTA (including LIN support), and 8 Simplified SPI (CSI) channels. All are implemented in the Serial Array Unit (SAU) and Serial Interface (SCI) modules, with flexible pin mapping via PIOR registers - enabling concurrent use of I²C for sensor buses, UART for diagnostics, and SPI for display or memory expansion.
