Product details
Overview
R7F100GMN3CFA#AA0 from Renesas is an RL78/G23 80-pin LQFP industrial-grade 16-bit MCU with 768 KB code flash, 48 KB RAM, and 8 KB data flash, operating from 1.6–5.5 V at -40 to +105°C. It integrates capacitive touch sensing (up to 64 keys), 12-bit ADC (26 channels), dual DAC, RTC, and low-power STOP/SNOOZE modes-enabling battery-powered HMI and sensor edge nodes.
For engineers reviewing the R7F100GMN3CFA#AA0 datasheet, R7F100GMN3CFA#AA0 pinout, R7F100GMN3CFA#AA0 application, or R7F100GMN3CFA#AA0 equivalent, key selection criteria include its 80-pin LQFP-0.65mm package, industrial temperature rating, integrated CTSU2L for mutual-capacitance touch, and SNOOZE mode sequencer for autonomous low-power sensor polling without CPU wake-up.
Technical Context
The R7F100GMN3CFA#AA0 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). Its SNOOZE mode sequencer executes up to 32 preconfigured commands-including ADC sampling, comparator comparison, and register arithmetic-without CPU, RAM, or flash activation.
Peripheral integration includes 16× 16-bit TAU timers, 4× I²C/Simplified I²C channels, 3× UARTA (LIN-capable), 3× CSI (SPI-compatible), and a logic/event link controller (ELCL) enabling hardware-triggered signal routing between peripherals-reducing software overhead in real-time control loops.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GMN3CFA#AA0?
The R7F100GMN3CFA#AA0 supports up to 32 MHz operation with its high-speed on-chip oscillator, guaranteed across the full 1.6–5.5 V supply range. At 32 MHz, minimum instruction execution time is 0.03125 µs. The device maintains full functionality-including ADC, CTSU2L, and UART-within this voltage and frequency envelope, with ±1.0% oscillator accuracy over -40 to +85°C.
Does the R7F100GMN3CFA#AA0 support hardware-based capacitive touch sensing, and what configurations are available?
Yes, the R7F100GMN3CFA#AA0 integrates the CTSU2L capacitive touch sensing unit, supporting both self-capacitance (up to 32 keys on single pins) and mutual-capacitance (8×8 matrix = 64 keys). It operates at VDD = 1.8–5.5 V, includes built-in noise suppression, and requires no external components beyond standard decoupling-making it ideal for rugged industrial touch panels.
How does the SNOOZE mode sequencer in the R7F100GMN3CFA#AA0 reduce system power consumption?
The SNOOZE mode sequencer in the R7F100GMN3CFA#AA0 executes up to 32 preloaded commands-including ADC conversions, comparator comparisons, and register arithmetic-without activating the CPU, flash, or RAM. This reduces active current to 1.2 µA, enabling battery-powered devices to perform periodic sensor reads and decision logic autonomously for years without host intervention.
Can the R7F100GMN3CFA#AA0 perform background data flash writes while executing application code from main flash memory?
Yes, the R7F100GMN3CFA#AA0 supports Background Operation (BGO) for its 8 KB data flash. Instructions can be fetched and executed from code flash memory while data flash is being rewritten-enabling real-time logging, parameter updates, or firmware patching without halting application execution or introducing timing jitter in time-critical tasks.
What peripheral interfaces does the R7F100GMN3CFA#AA0 provide for industrial communication protocols like Modbus or LIN?
The R7F100GMN3CFA#AA0 includes three UARTA modules, each supporting LIN-bus physical layer compliance and configurable framing for Modbus RTU. UARTA peripherals feature automatic direction control, break detection, and selectable oversampling-allowing direct connection to RS-485 transceivers or LIN transceivers without external glue logic or software bit-banging.
