Product details
Overview
R7F100GPK3CFB#BA0 from Renesas is a 100-pin LFQFP, 5.0-V tolerant, industrial-grade RL78/G23 16-bit MCU with 256 KB code flash, 8 KB data flash, 24 KB RAM, 12-bit ADC (26 channels), and integrated capacitive touch sensing unit (CTSU2L) for human-machine interface applications in smart appliances and industrial controls.
For engineers reviewing the R7F100GPK3CFB#BA0 datasheet, R7F100GPK3CFB#BA0 pinout, R7F100GPK3CFB#BA0 application, or R7F100GPK3CFB#BA0 equivalent, this page delivers verified electrical specs, validated package mapping, confirmed peripheral integration (SNOOZE mode sequencer, ELCL, RTC), and real-world use-case context for low-power embedded design.
Technical Context
The R7F100GPK3CFB#BA0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs min @ 32 MHz high-speed oscillator or 30.5 µs @ 32.768 kHz subsystem clock). It supports ultra-low-power operation with 41 µA/MHz active current and 210 nA data retention current for its 24 KB RAM.
It integrates a SNOOZE mode sequencer (SMS) enabling up to 32 sequential low-power operations without CPU wake-up, plus an Event Link Controller (ELCL) for hardware-level signal routing between peripherals-eliminating software overhead for sensor-triggered actions and real-time event chaining.
