Product details
Overview
R7F100GLF3CFB#AA0 from Renesas is a 64-pin LFQFP, industrial-grade RL78/G23 16-bit MCU with 512 KB code flash, 8 KB data flash, and 48 KB RAM, operating from 1.6–5.5 V. It delivers ultra-low power (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (up to 64 keys), and dual-clock domain operation for battery-powered industrial control and sensor interface applications.
For engineers reviewing the R7F100GLF3CFB#AA0 datasheet, R7F100GLF3CFB#AA0 pinout, R7F100GLF3CFB#AA0 application, or R7F100GLF3CFB#AA0 equivalent, key selection criteria include its 64-pin LFQFP-0.5 mm package, -40°C to +105°C industrial temperature rating, SNOOZE mode sequencer for autonomous low-power sensing, and hardware-accelerated CTSU2L capacitive touch unit supporting self- and mutual-capacitance configurations.
Technical Context
The R7F100GLF3CFB#AA0 implements the RL78 CPU core with a 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz high-speed oscillator) to 30.5 µs (32.768 kHz subsystem clock). Its SNOOZE mode sequencer executes up to 32 configurable commands-including comparisons and arithmetic-without CPU, RAM, or flash activation, enabling deterministic low-power sensor polling.
Peripheral integration includes a Logic and Event Link Controller (ELCL) for programmable signal routing between peripherals, a Data Transfer Controller (DTC) with chain transfer support, and a Realtime Clock with alarm and correction functions. The device supports background data flash rewriting (BGO) and flash shield window security for firmware protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78 16-bit CISC with 3-stage pipeline; enables deterministic real-time response in resource-constrained embedded systems. |
| Flash Memory | 512 KB code flash + 8 KB data flash; supports self-programming with boot swapping and flash shield window for secure firmware updates. |
| RAM | 48 KB on-chip RAM; retains full 4 KB at 210 nA in STOP mode for rapid wake-up with state preservation. |
| Operating Voltage | 1.6–5.5 V single supply; eliminates need for external voltage regulators in multi-rail industrial designs. |
| Power Modes | HALT, STOP, and SNOOZE modes; SNOOZE enables autonomous peripheral sequencing without CPU wake-up, reducing average system current. |

Pinout & Package
Package: 64-pin LFQFP (10 × 10 mm, 0.50-mm pitch), industrial-grade (–40°C to +105°C), tray packaging (#AA0).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P121 / X1 / XT1 / VBAT / EI121 | Primary crystal oscillator input / backup battery supply | Enables precision 32.768 kHz RTC timing and maintains RTC during main power loss when VBAT is connected. |
| P122 / X2 / EXCLK / XT2 / EXCLKS / EI122 | Secondary crystal oscillator input / external clock source | Supports high-accuracy main system clock (e.g., 4–24 MHz crystal) or external clock injection for synchronization. |
| P60 / EO60 / CCD04 / SCLA0 | I²C bus clock output / capacitive sensing channel / general-purpose port | Configurable as I²C clock line (SCL), CTSU electrode driver, or GPIO-enabling shared pin usage across sensing and communication. |
| P61 / EO61 / CCD05 / SDAA0 | I²C bus data output / capacitive sensing channel / general-purpose port | Functions as I²C data line (SDA), CTSU electrode driver, or GPIO-reducing pin count for combined touch + I²C slave interfaces. |
| P30 / VCOUT0 / TSCAP / EI30 / INTP3 / RTC1HZ / SCK11 / SCL11 | Touch sense reference / capacitive sensing analog input / RTC interrupt output | Provides dedicated analog input for CTSU, outputs 1 Hz RTC tick, and serves as SPI clock for secondary interface-central to low-power touch timing. |
| REGC | Regulator capacitor connection | Must be connected to VSS via 0.47–1 µF capacitor to stabilize internal LDO; omission causes unstable operation or reset failures. |
Key Features
| Feature | Design Value |
|---|---|
| SNOOZE Mode Sequencer (SMS) | Executes up to 32 preloaded commands (e.g., ADC sampling, comparison, conditional branching) autonomously-eliminating CPU wake-ups and cutting average current in periodic sensing tasks. |
| Capacitive Touch Sensing Unit (CTSU2L) | Hardware-accelerated touch engine supporting both self-capacitance (32 keys) and mutual-capacitance (64 keys) with built-in noise cancellation-enables robust touch UI in noisy industrial environments. |
| Data Flash Background Operation (BGO) | Permits full CPU execution from code flash while rewriting data flash-enabling seamless logging or parameter updates without interrupting real-time control loops. |
| Logic and Event Link Controller (ELCL) | Configurable hardware logic block that routes signals between peripherals (e.g., trigger ADC conversion on timer match)-reducing software overhead and jitter in time-critical sequences. |
| High-Accuracy On-Chip Oscillators | ±1.0% accuracy across 1.8–5.5 V and –20°C to +85°C for 32 MHz high-speed clock-removes need for external crystal in cost-sensitive applications where <1% timing tolerance is acceptable. |
| Controlled Current Drive Ports | 6–8 pins with programmable drive strength (e.g., 10 mA sink/source); directly drives LEDs or small relays without external drivers-reducing BOM count in HMI and actuator control. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GLL3CFB#AA0 | Same 64-pin LFQFP package and 512 KB flash, but with 32 KB RAM (vs. 48 KB) and no CTSU2L capacitive touch unit. | Targeted at non-touch applications requiring lower memory footprint and reduced peripheral count-e.g., simple serial gateway or timer-based sequencer. | Select when touch sensing is unnecessary and cost optimization is prioritized over future feature scalability. |
| R7F100GMJ3CFB#AA0 | 80-pin LFQFP variant with identical 512 KB flash, 48 KB RAM, and CTSU2L, but adds 4 extra ADC channels and 2 additional UARTA channels. | Suitable for higher I/O density requirements-e.g., multi-sensor industrial logger with simultaneous CAN+UART+I²C interfaces. | Choose when board layout allows larger package and additional analog/digital I/O is required beyond R7F100GLF3CFB#AA0's 64-pin capability. |
Compared with R7F100GLL3CFB#AA0, the R7F100GLF3CFB#AA0 provides 16 KB more RAM and integrated CTSU2L for touch UI-making it superior for HMI-rich industrial devices.

FAQ
What is the maximum operating temperature range for the R7F100GLF3CFB#AA0?
The R7F100GLF3CFB#AA0 is rated for industrial operation from –40°C to +105°C, as indicated by the "C" field-of-application code and "3" ambient temperature suffix in its part number. This rating applies to the full electrical specification including flash programming, ADC accuracy, and CTSU2L touch performance-validated per Renesas' reliability testing standards.
Does the R7F100GLF3CFB#AA0 support in-system programming via standard debug interfaces?
Yes, the R7F100GLF3CFB#AA0 supports on-chip debugging and flash programming via the on-chip debug interface using Renesas E2 or E2 Lite debuggers. It requires only the RESET, SWCLK, and SWDIO pins (plus power and ground) for full read/write/erase functionality-including secure flash shield window configuration and data flash BGO operations.
How many capacitive touch channels does the R7F100GLF3CFB#AA0 support in mutual-capacitance mode?
The R7F100GLF3CFB#AA0 supports up to 64 keys in mutual-capacitance mode using an 8 × 8 matrix configuration via its CTSU2L unit. This requires 16 dedicated pins (8 for X-lines, 8 for Y-lines), all of which are available in the 64-pin LFQFP package-confirmed in the RL78/G23 datasheet Section 1.6 and CTSU2L peripheral description.
Can the R7F100GLF3CFB#AA0 operate from a 1.8-V supply while maintaining full peripheral functionality?
Yes, the R7F100GLF3CFB#AA0 operates across 1.6–5.5 V, and all peripherals-including CTSU2L, ADC, UARTA, and RTC-are fully functional at 1.8 V. The CTSU2L unit explicitly specifies VDD = 1.8–5.5 V operation in the datasheet, and the high-speed on-chip oscillator maintains ±1.0% accuracy down to 1.8 V, ensuring timing integrity in low-voltage battery systems.
What is the purpose of the REGC pin on the R7F100GLF3CFB#AA0, and how must it be connected?
The REGC pin on the R7F100GLF3CFB#AA0 connects to the internal LDO regulator's stabilization capacitor. It must be connected to VSS via a 0.47–1 µF ceramic capacitor placed as close as possible to the pin. Failure to do so results in unstable internal voltage regulation, causing erratic resets, flash corruption during programming, or failure to enter/exit STOP mode reliably.
