Product details
Overview
R7F100GLG3CFB#BA0 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 consumption (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (CTSU2L), RTC, and dual 16-bit timer arrays - deployed in battery-powered industrial HMI and sensor node control.
For engineers reviewing the R7F100GLG3CFB#BA0 datasheet, R7F100GLG3CFB#BA0 pinout, R7F100GLG3CFB#BA0 application, or R7F100GLG3CFB#BA0 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 supporting up to 64 mutual-capacitance keys.
Technical Context
The R7F100GLG3CFB#BA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting variable instruction execution time (0.03125 µs at 32 MHz high-speed mode; 30.5 µs at 32.768 kHz ultra-low-speed mode). It integrates a dedicated SNOOZE mode sequencer (SMS) that executes up to 32 sequential commands-including comparisons and calculations-without CPU, RAM, or flash activation.
Peripheral integration includes Logic and Event Link Controller (ELCL) for configurable signal routing between peripherals, Data Transfer Controller (DTC) with chain transfer support, and dual serial interface sets: up to 10 I²C/Simplified I²C channels and up to 6 UART/UARTA (LIN-supported) channels, all accessible via multiplexed I/O pins on the 64-pin LFQFP package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78 16-bit CISC with 3-stage pipeline; enables deterministic real-time response and low gate count. |
| Flash Memory | 512 KB code flash + 8 KB data flash; supports background operation (BGO) and 1M rewrite cycles for firmware/data updates. |

Pinout & Package
Package: 64-pin LFQFP (10 × 10 mm, 0.50-mm pitch), industrial-grade (–40°C to +105°C), tray packaging (#BA0).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P121 / X1 / XT1 / VBAT / EI121 | Primary crystal oscillator input / backup battery input | Enables precise 32.768 kHz RTC timing and maintains RTC during main power loss when VBAT is supplied. |
| P122 / X2 / EXCLK / XT2 / EXCLKS / EI122 | Crystal oscillator output / external clock input | Supports high-accuracy system clock generation (up to 32 MHz) or external clock injection for synchronization. |
| P137 / EI137 / INTP0 | External interrupt input / dedicated interrupt pin | Provides lowest-latency wake-up source from STOP/HALT modes for critical event handling. |
| P30 / VCOUT0 / TSCAP / EI30 / INTP3 / RTC1HZ / SCK11 / SCL11 | Capacitive touch sense channel / RTC 1 Hz output / I²C interface | Single pin serves as CTSU2L analog input, RTC tick output, and I²C clock-reducing pin count in space-constrained designs. |
| P60 / EO60 / CCD04 / SCLA0 | I²C bus clock output / CTSU2L channel / general-purpose port | Hardware-mapped I²C clock line with CTSU2L sensing capability enables shared pin usage across communication and HMI functions. |
| P61 / EO61 / CCD05 / SDAA0 | I²C bus data output / CTSU2L channel / general-purpose port | Hardware-mapped I²C data line with CTSU2L sensing allows concurrent I²C comms and capacitive touch on same pins. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GLL3CFB#BA0 | Same 64-pin LFQFP package and 512 KB flash, but with 32 KB RAM (vs. 48 KB) and no CTSU2L support. | Targeted at cost-optimized industrial control where capacitive touch is unnecessary and RAM demand is lower. | Select when CTSU2L and full 48 KB RAM are not required-reduces BOM cost without changing PCB layout. |
| R7F100GMG3CFB#BA0 | 80-pin LFQFP variant with identical 512 KB flash/48 KB RAM, but adds 2 extra UARTA channels and 4 additional ADC inputs. | Suitable for more complex systems requiring expanded serial connectivity and analog sensing headroom. | Choose when pin count expansion is acceptable and additional UARTA/ADC resources are needed-same core/peripheral IP and software compatibility. |
Compared with R7F100GLG3CFB#BA0, R7F100GLL3CFB#BA0 reduces RAM and removes CTSU2L for cost savings in non-touch applications, while R7F100GMG3CFB#BA0 scales pin count and peripheral count for higher I/O density-both maintain identical flash size, voltage range, and industrial temperature grade.

FAQ
What is the maximum operating frequency and clock accuracy of the R7F100GLG3CFB#BA0?
The R7F100GLG3CFB#BA0 supports a maximum system clock of 32 MHz using its high-speed on-chip oscillator, which maintains ±1.0% accuracy across 1.8–5.5 V supply and –20°C to +85°C ambient temperature. External crystals up to 32 MHz are also supported via P121/P122 pins for higher precision timing-critical applications.
Does the R7F100GLG3CFB#BA0 support capacitive touch sensing, and how many keys can it handle?
Yes, the R7F100GLG3CFB#BA0 integrates the CTSU2L capacitive touch sensing unit. 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-all without external RC components and with built-in noise cancellation.
What power-saving modes are available on the R7F100GLG3CFB#BA0, and what is the lowest current draw?
The R7F100GLG3CFB#BA0 offers HALT, STOP, and SNOOZE modes. In STOP mode with 4 KB RAM retention, it draws just 210 nA. The SNOOZE mode sequencer enables autonomous peripheral operation (e.g., ADC sampling, comparisons) at sub-µA average current-ideal for battery-powered wake-on-event designs.
Can the R7F100GLG3CFB#BA0 execute code while rewriting data flash memory?
Yes, the R7F100GLG3CFB#BA0 supports Background Operation (BGO) for data flash. Instructions can be fetched and executed from code flash memory while data flash is being rewritten-enabling seamless firmware parameter updates or logging without halting application execution.
What is the purpose of the REGC pin on the R7F100GLG3CFB#BA0, and how must it be connected?
The REGC pin on the R7F100GLG3CFB#BA0 connects to the internal LDO regulator's stabilization capacitor. It must be connected directly to VSS via a 0.47 µF to 1 µF ceramic capacitor to ensure stable operation of the analog circuitry, RTC, and CTSU2L-failure to do so may cause erratic touch sensing or RTC drift.
