Product details
Overview
R7F100GGJ2DFB#BA0 from Renesas is a 48-pin LFQFP-packaged RL78/G23 16-bit microcontroller with 256 KB code flash, 8 KB data flash, and 24 KB RAM, operating from 1.6–5.5 V. It delivers ultra-low power consumption (41 µA/MHz active, 210 nA data retention), integrates capacitive touch sensing (CTSU2L), RTC, 16-bit TAU timers, UARTA/IICA/SAU interfaces, and supports industrial temperature range (−40 to +105°C) for embedded control in smart appliances and industrial HMI.
For engineers reviewing the R7F100GGJ2DFB#BA0 datasheet, R7F100GGJ2DFB#BA0 pinout, R7F100GGJ2DFB#BA0 application, or R7F100GGJ2DFB#BA0 equivalent, key selection criteria include verified 48-pin LFQFP mechanical compatibility, confirmed 256 KB flash/24 KB RAM memory mapping, validated CTSU2L self/mutual-capacitance support up to 64 keys, and documented SNOOZE mode sequencer operation without CPU wake-up.
Technical Context
The RL78/G23 core implements a 3-stage pipeline CISC architecture with configurable instruction timing (0.03125 µs at 32 MHz high-speed mode; 30.5 µs at 32.768 kHz ultra-low-speed mode), supporting multiply/divide/MAC instructions and 1 MB address space. It includes dedicated hardware accelerators: SNOOZE mode sequencer (32-step command execution without CPU/RAM/flash activation) and ELCL event logic for autonomous peripheral signal routing.
Power management integrates HALT/STOP/SNOOZE modes with sub-µA retention, dual voltage detectors (LVD0/LVD1), and POR. Peripheral integration includes 16-bit TAU (12 channels), 32-bit interval timer, 8–26-channel 8/10/12-bit ADC with internal 1.48 V reference and temperature sensor, 2-channel 8-bit DAC, 2-channel comparator with selectable reference sources, and remote control signal receiver with 4-pattern matching.
