Product details
Overview
R7F100GLH3CFA#BA0 from Renesas is an RL78/G23 64-pin industrial-grade 16-bit MCU with 128 KB code flash, 8 KB data flash, and 16 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), integrated capacitive touch sensing (CTSU2L), 16-bit TAU timers, RTC, and dual UART/I²C/SPI interfaces - deployed in smart sensors and battery-powered HMI control units.
For engineers reviewing the R7F100GLH3CFA#BA0 datasheet, R7F100GLH3CFA#BA0 pinout, R7F100GLH3CFA#BA0 application, or R7F100GLH3CFA#BA0 equivalent, key selection criteria include its 64-pin LQFP-0.65mm package, industrial temperature rating, CTSU2L support for up to 64-key mutual-capacitance touch panels, 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 @ 32 MHz high-speed oscillator or 30.5 µs @ 32.768 kHz subsystem clock). It integrates a dedicated SNOOZE mode sequencer (SMS) supporting 32 sequential commands across 21 operations - enabling autonomous analog/digital event processing while keeping CPU, flash, and RAM powered down.
Peripheral integration includes a Logic & 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- and mutual-capacitance modes - with internal voltage references (1.48 V), temperature sensor, and 8-/10-/12-bit ADC (up to 26 channels).
