Product details
Overview
R7F100GGG3CFB#BA0 from Renesas is a 48-pin LFQFP-packaged RL78/G23 16-bit microcontroller with 128 KB code flash, 8 KB data flash, and 16 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, 16-bit TAU timers, and dual UART/I²C/SPI interfaces - deployed in industrial sensor nodes and battery-powered HMI control units.
For engineers reviewing the R7F100GGG3CFB#BA0 datasheet, R7F100GGG3CFB#BA0 pinout, R7F100GGG3CFB#BA0 application, or R7F100GGG3CFB#BA0 equivalent, key selection criteria include its -40 to +105°C industrial temperature rating, 48-pin LFQFP (7 × 7 mm, 0.50-mm pitch) package, and verified support for SNOOZE mode sequencer-driven low-power wake-up sequences without CPU intervention.
Technical Context
The RL78/G23 core implements a 3-stage pipeline CISC architecture with configurable instruction timing (0.03125 µs min @ 32 MHz high-speed oscillator or 30.5 µs @ 32.768 kHz subsystem clock). It integrates a dedicated SNOOZE mode sequencer (SMS) supporting up to 32 sequential low-power operations using 21 command types - enabling autonomous sensor polling and threshold evaluation without RAM/CPU activation.
Peripheral integration includes a Logic and Event Link Controller (ELCL) for hardware-triggered signal routing between peripherals, a Data Transfer Controller (DTC) with chain transfer capability, and a capacitive sensing unit (CTSU2L) supporting both self-capacitance (32 keys) and mutual capacitance (8×8 matrix) configurations under 1.8–5.5 V operation.
