Product details
Overview
R7F100GML3CFA#AA0 from Renesas is an RL78/G23 80-pin industrial-grade 16-bit MCU with 512 KB code flash, 48 KB RAM, and 8 KB data flash, operating from 1.6–5.5 V. It delivers true low-power operation (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (CTSU2L), and dual-clock domain support for ultra-low-power SNOOZE mode execution in battery-powered industrial HMI and sensor node applications.
For engineers reviewing the R7F100GML3CFA#AA0 datasheet, R7F100GML3CFA#AA0 pinout, R7F100GML3CFA#AA0 application, or R7F100GML3CFA#AA0 equivalent, key selection considerations include its 80-pin LQFP-0.65mm package, -40°C to +105°C industrial temperature grade, 512 KB flash/48 KB RAM memory configuration, and integrated CTSU2L capacitive sensing unit supporting up to 64 keys in mutual-capacitance matrix mode.
Technical Context
The R7F100GML3CFA#AA0 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed oscillator) to 30.5 µs (32.768 kHz subsystem clock). Its power management includes HALT, STOP, and SNOOZE modes-enabling CPU-off background processing via the SNOOZE Mode Sequencer (SMS) with 32 programmable steps and 21 command types.
Peripheral integration includes a Logic and Event Link Controller (ELCL) for configurable signal routing between peripherals, a Data Transfer Controller (DTC) supporting chain transfer, and a full suite of analog resources: 12-bit A/D converter (26 channels), 8-bit D/A converter (2 channels), 2-channel comparator with selectable internal/external reference, and real-time clock with alarm and correction functions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GML3CFA#BA0 | Identical silicon, same 80-pin LQFP package and 512 KB/48 KB memory, but shipped in alternate tray packaging (#BA0 vs #AA0). | No functional difference; used interchangeably in production where packaging logistics differ. | Select #BA0 only when required by distributor inventory or assembly line tape-and-reel compatibility requirements. |
| R7F100GLL3CFA#AA0 | Same RL78/G23 family, 64-pin LQFP, but reduced memory: 512 KB flash / 48 KB RAM / 8 KB data flash - identical peripheral set except for fewer I/O (48 vs 64). | Suitable for space-constrained designs needing fewer analog/digital I/O lines but retaining full CTSU2L, SMS, and BGO functionality. | Choose when board area is limited and I/O count ≤48 suffices; retains all critical low-power and sensing features at lower pin count. |
Compared with R7F100GML3CFA#AA0, the #BA0 variant offers identical electrical and functional performance with alternate packaging, while the R7F100GLL3CFA#AA0 reduces pin count and I/O count by 20% without sacrificing memory size or core peripheral capabilities-making it optimal for compact industrial controllers where full 80-pin I/O is unnecessary.

FAQ
What is the maximum operating frequency and corresponding instruction cycle time for the R7F100GML3CFA#AA0?
The R7F100GML3CFA#AA0 supports a maximum CPU clock of 32 MHz using the high-speed on-chip oscillator. At this frequency, the minimum instruction execution time is 0.03125 µs per instruction cycle. This timing is achievable across the full industrial temperature range (-40°C to +105°C) and supply voltage (1.6–5.5 V), enabling deterministic real-time control in motor drives and PLCs.
Does the R7F100GML3CFA#AA0 support hardware-accelerated capacitive touch sensing, and how many electrodes can it manage?
Yes, the R7F100GML3CFA#AA0 integrates the CTSU2L (Capacitive Touch Sensing Unit Level 2) hardware accelerator. It supports up to 32 self-capacitance keys (one pin per key) or up to 64 mutual-capacitance keys in an 8×8 matrix configuration. Electrode assignment is flexible via register configuration, and scanning operates independently of the CPU during SNOOZE mode-reducing system power and firmware complexity.
What are the data flash endurance and background operation capabilities of the R7F100GML3CFA#AA0?
The R7F100GML3CFA#AA0 includes 8 KB of data flash rated for 1,000,000 write/erase cycles (typical). It supports Background Operation (BGO), allowing the CPU to execute instructions from program flash while simultaneously erasing or programming data flash sectors. This enables seamless field firmware updates, parameter logging, and calibration storage without halting real-time application tasks.
Can the R7F100GML3CFA#AA0 operate reliably in industrial environments with wide temperature and voltage variations?
Yes, the R7F100GML3CFA#AA0 is qualified for industrial applications with an operating ambient temperature range of -40°C to +105°C and supply voltage range of 1.6 V to 5.5 V. Its on-chip voltage detectors (LVD0/LVD1), POR circuit, and ±1.0% high-speed oscillator accuracy across voltage and temperature ensure robust startup, brown-out protection, and timing integrity in harsh factory-floor or outdoor deployments.
How does the SNOOZE Mode Sequencer (SMS) in the R7F100GML3CFA#AA0 reduce system power consumption?
The SNOOZE Mode Sequencer (SMS) in the R7F100GML3CFA#AA0 executes up to 32 pre-programmed operations-including ADC sampling, value comparison, GPIO toggling, and timer starts-without waking the CPU, flash, or RAM. By offloading periodic sensing and control tasks to dedicated hardware, SMS cuts average system current to sub-µA levels, extending battery life in wireless sensors and portable HMIs far beyond what STOP-mode-only MCUs achieve.
