Product details
Overview
R7F100GLN3CFA#AA0 from Renesas is a 64-pin, industrial-grade RL78/G23 16-bit MCU with 512 KB code flash, 48 KB RAM, and 8 KB data flash, 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 (up to 64 keys), and supports real-time clock, multiple UART/I²C/SPI interfaces, and SNOOZE mode for battery-powered HMI applications.
For engineers reviewing the R7F100GLN3CFA#AA0 datasheet, R7F100GLN3CFA#AA0 pinout, R7F100GLN3CFA#AA0 application, or R7F100GLN3CFA#AA0 equivalent, key selection criteria include its 64-pin LQFP-0.65mm package, -40°C to +105°C industrial temperature rating, 512 KB flash/48 KB RAM configuration, and integrated CTSU2L capacitive sensing unit for touch interface design.
Technical Context
The R7F100GLN3CFA#AA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting variable instruction execution time (0.03125 µs at 32 MHz high-speed mode or 30.5 µs at 32.768 kHz ultra-low-speed mode). It integrates a SNOOZE mode sequencer (SMS) enabling up to 32 low-power autonomous operations without CPU wake-up, and an Event Link Controller (ELCL) for configurable peripheral event chaining.
Its analog subsystem includes an 8-/10-/12-bit ADC (26 channels), dual 8-bit DAC outputs (0–VDD range), two comparators with selectable internal/external reference, and a dedicated capacitive sensing unit (CTSU2L) supporting both self- and mutual-capacitance methods. Power management features HALT, STOP, and SNOOZE modes with fast STOP wakeup and 210-nA RAM retention.
