Product details
Overview
R7F100GLF3CFB#BA0 from Renesas is a 64-pin LFQFP, 512-KB flash, 48-KB RAM RL78/G23 16-bit MCU designed for ultra-low-power industrial applications. It delivers 41-µA/MHz active current, 210-nA data retention, 1.6–5.5 V operation, and integrates capacitive touch sensing (CTSU2L), RTC, 16-bit TAU timers, UARTA/IICA/SAU interfaces, and SNOOZE mode sequencer for autonomous low-power sensor monitoring in battery-powered HMI systems.
For engineers reviewing the R7F100GLF3CFB#BA0 datasheet, R7F100GLF3CFB#BA0 pinout, R7F100GLF3CFB#BA0 application, or R7F100GLF3CFB#BA0 equivalent, key selection criteria include its 64-pin LFQFP-0.5 mm package, -40 to +105°C industrial temperature grade, 512-KB code flash with 8-KB data flash, and support for self-programming with boot swapping and flash shield window.
Technical Context
The R7F100GLF3CFB#BA0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). Its power management includes HALT, STOP, and SNOOZE modes-enabling sub-µA wake-up-triggered operation without CPU involvement via the SMS sequencer.
Peripheral integration includes a 21-instruction SNOOZE mode sequencer (SMS) for autonomous sensor polling, Logic & Event Link Controller (ELCL) for configurable event routing between peripherals, and CTSU2L capacitive sensing unit supporting up to 64 keys in mutual-capacitance matrix (8×8) or 32 keys in self-capacitance mode-all operating at VDD = 1.8–5.5 V.
