Product details
Overview
R7F100GMH3CFA#BA0 from Renesas is an RL78/G23 80-pin industrial-grade 16-bit MCU with 192 KB code flash, 8 KB data flash, and 20 KB RAM, operating from 1.6–5.5 V at -40 to +105°C. It delivers true low-power operation (41 µA/MHz active, 210 nA data retention), integrates capacitive touch sensing (CTSU2L), RTC, 16-bit TAU timers, and multiple serial interfaces including UARTA, IICA, and SAU for embedded control in resource-constrained industrial systems.
For engineers reviewing the R7F100GMH3CFA#BA0 datasheet, R7F100GMH3CFA#BA0 pinout, R7F100GMH3CFA#BA0 application, or R7F100GMH3CFA#BA0 equivalent, key selection criteria include its 80-pin LQFP-0.65mm package, industrial temperature rating (3C), 192 KB flash/20 KB RAM configuration, CTSU2L capacitive sensing support, and SNOOZE mode sequencer for ultra-low-power sensor polling without CPU wake-up.
Technical Context
The RL78/G23 core implements a 3-stage pipeline CISC architecture with configurable instruction timing-0.03125 µs min at 32 MHz (high-speed oscillator) or 30.5 µs at 32.768 kHz (subsystem clock). It supports multiply/divide/MAC instructions and a 1 MB address space with four banks of 8×8-bit general-purpose registers.
Power management includes HALT, STOP, and SNOOZE modes; the latter uses a dedicated sequencer executing up to 32 preconfigured commands (e.g., ADC sampling, comparison, GPIO toggle) without CPU, flash, or RAM activation. Peripheral event linking (ELCL) enables hardware-triggered signal routing between modules like timers, ADC, and communication units.
