Product details
Overview
R7F100GPN3CFA#BA0 from Renesas is a 100-pin, industrial-grade RL78/G23 16-bit MCU with 256 KB code flash, 8 KB data flash, and 24 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), and dual-clock domain operation supporting high-speed (32 MHz) and ultra-low-power (32.768 kHz) modes for battery-powered HMI and sensor interface applications.
For engineers reviewing the R7F100GPN3CFA#BA0 datasheet, R7F100GPN3CFA#BA0 pinout, R7F100GPN3CFA#BA0 application, or R7F100GPN3CFA#BA0 equivalent, key selection considerations include its LQFP-100 (0.65 mm pitch) 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 keys in mutual-capacitance matrix configuration.
Technical Context
The R7F100GPN3CFA#BA0 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). It integrates a dedicated SNOOZE mode sequencer (SMS) capable of executing 32 sequential operations-including comparisons and calculations-without CPU, RAM, or flash activation, enabling deterministic ultra-low-power wake-up control.
Its peripheral set includes 16-bit TAU timers (12 channels), RTC with alarm and correction, 12-bit ADC (26 channels), 8-bit DAC (2 channels), 2 comparators, and flexible serial interfaces: up to 6 UARTA channels (LIN-support), 10 IICA channels, and 8 CSI channels-all configurable via peripheral I/O redirection register (PIOR) for layout optimization.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit ultra-low-power MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GPK3CFA#BA0 | Same RL78/G23 family, 192 KB flash / 20 KB RAM / 100-pin LQFP; reduced memory and peripheral count (e.g., fewer ADC channels). | Targeted at cost-sensitive HMI with simpler touch requirements (≤16 keys) and no RTC-critical logging. | Select when application fits within smaller memory footprint and does not require full 26-channel ADC or dual DAC functionality. |
| R7F100GPL3CFA#BA0 | Same package and temperature grade, but 128 KB flash / 16 KB RAM; lacks CTSU2L and has only 8-channel ADC. | Suitable for basic industrial control where capacitive touch is unnecessary and analog sensing is minimal. | Choose only if design omits touch interface and uses ≤8 analog sensors-avoids paying for unused CTSU2L and memory resources. |

The R7F100GPN3CFA#BA0 operates at up to 32 MHz using its high-speed on-chip oscillator and supports a supply voltage range of 1.6 V to 5.5 V. Its ±1.0% oscillator accuracy (at VDD = 1.8–5.5 V, TA = −20 to +85°C) ensures reliable timing for UART communication and RTC functions without external crystals in many applications.
Does the R7F100GPN3CFA#BA0 support capacitive touch sensing, and how many keys can it handle?
Yes, the R7F100GPN3CFA#BA0 integrates the CTSU2L capacitive touch sensing unit supporting both self-capacitance (up to 32 keys) and mutual-capacitance (8×8 matrix = 64 keys) configurations. It operates across the full VDD range of 1.8–5.5 V and includes hardware acceleration for noise rejection and auto-calibration-eliminating the need for external touch controllers.
What low-power modes are available on the R7F100GPN3CFA#BA0, and what are their typical current draws?
The R7F100GPN3CFA#BA0 offers HALT, STOP, and SNOOZE modes. In STOP mode with RAM retention, it draws ≤1 µA; in data retention mode (RAM only), it consumes 210 nA. Active-mode current is 41 µA/MHz at 32 MHz. The SNOOZE mode sequencer enables autonomous peripheral operation without CPU wake-up-reducing average current significantly in periodic sensing applications.
Can the R7F100GPN3CFA#BA0 perform background data flash writes while executing code from program memory?
Yes, the R7F100GPN3CFA#BA0 supports Background Operation (BGO) for data flash. This allows the CPU to execute instructions from code flash while simultaneously rewriting data flash memory-enabling seamless firmware updates, parameter logging, and OTA configuration changes without interrupting real-time application execution.
