Overview
R7F100GPN2DFA#BA0 from Renesas is a 100-pin LFQFP, 1.6–5.5 V RL78/G23 16-bit MCU with 192 KB code flash, 8 KB data flash, 20 KB RAM, and integrated capacitive touch sensing (CTSU2L), designed for low-power consumer HMI applications including appliance control panels and smart home interfaces.
For engineers reviewing the R7F100GPN2DFA#BA0 datasheet, R7F100GPN2DFA#BA0 pinout, R7F100GPN2DFA#BA0 application, or R7F100GPN2DFA#BA0 equivalent, key selection criteria include its 100-pin LFQFP-0.5 mm package, -40 to +85°C industrial-grade temperature range, 192 KB flash/20 KB RAM memory configuration, and support for SNOOZE mode sequencer and ELCL event linking in battery-constrained embedded systems.
Technical Context
The R7F100GPN2DFA#BA0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs at 32 MHz high-speed mode or 30.5 µs at 32.768 kHz ultra-low-speed mode). It integrates a SNOOZE mode sequencer (SMS) supporting up to 32 sequential low-power operations without CPU wake-up.
It features a Logic and Event Link Controller (ELCL) enabling hardware-level signal routing between peripherals, plus a Capacitive Touch Sensing Unit (CTSU2L) supporting both self-capacitance (up to 32 keys) and mutual capacitance (8×8 matrix, up to 64 keys) under VDD = 1.8–5.5 V operation.
