Product details
Overview
R7F100GPN3CFB#BA0 from Renesas is a 100-pin LFQFP, 0.50-mm pitch, industrial-grade (−40 to +105°C) RL78/G23 16-bit MCU with 192 KB code flash, 8 KB data flash, and 20 KB RAM. It features ultra-low power operation (41 µA/MHz), 32-channel capacitive touch sensing, 12-bit ADC (26 channels), dual 8-bit DACs, and integrated RTC with alarm and correction.
For engineers reviewing the R7F100GPN3CFB#BA0 datasheet, R7F100GPN3CFB#BA0 pinout, R7F100GPN3CFB#BA0 application, or R7F100GPN3CFB#BA0 equivalent, key selection criteria include its 100-pin LFQFP package, 192 KB flash/20 KB RAM memory configuration, industrial temperature rating, and support for SNOOZE mode sequencer and ELCL event linking in battery-constrained HMI and sensor-control systems.
Technical Context
The R7F100GPN3CFB#BA0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). It integrates a SNOOZE mode sequencer (SMS) capable of executing up to 32 low-power processes without CPU wake-up, and an Event Link Controller (ELCL) enabling hardware-level signal routing between peripherals like timers, ADC, and communication interfaces.
Power management includes HALT, STOP, and SNOOZE modes with 210-nA data retention current for 4 KB RAM, POR, and dual voltage detectors (LVD0/LVD1). Clock sources comprise high-accuracy ±1.0% on-chip oscillators (1–32 MHz), 32.768-kHz low-speed oscillator, and external crystal support (X1/X2 up to 20 MHz).

Does the R7F100GPN3CFB#BA0 support hardware-based capacitive touch sensing, and how many keys can it handle?
Yes, the R7F100GPN3CFB#BA0 integrates the CTSU2L capacitive sensing unit. It supports up to 32 keys in self-capacitance mode (one pin per key) or up to 64 keys in mutual-capacitance matrix mode (8 × 8 configuration). All sensing is performed in hardware with built-in noise cancellation and auto-calibration, eliminating the need for external touch controller ICs.
What are the flash memory organization and write endurance specifications for the R7F100GPN3CFB#BA0?
The R7F100GPN3CFB#BA0 contains 192 KB of code flash memory organized in 2 KB blocks, and 8 KB of data flash memory. Data flash supports background operation (BGO) and guarantees 1,000,000 write/erase cycles (typical).
