Product details
Overview
R7F100GGG2DFB#BA0 from Renesas is an RL78/G23 48-pin LFQFP microcontroller with 128 KB code flash, 8 KB data flash, and 16 KB RAM, 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 (CTSU2L), 12-bit ADC (26 channels), dual DAC, RTC, and multiple serial interfaces including UARTA, IICA, and CSI for industrial control and sensor node applications.
For engineers reviewing the R7F100GGG2DFB#BA0 datasheet, R7F100GGG2DFB#BA0 pinout, R7F100GGG2DFB#BA0 application, or R7F100GGG2DFB#BA0 equivalent, key selection criteria include its 48-pin LFQFP-0.5 mm package, -40 to +105°C industrial temperature grade, SNOOZE mode sequencer for autonomous low-power operation, and hardware ELCL for event-driven peripheral coordination without CPU intervention.
Technical Context
The R7F100GGG2DFB#BA0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode). Its SNOOZE mode sequencer (SMS) executes up to 32 preconfigured commands-including comparisons and calculations-without waking the CPU, flash, or RAM.
Peripheral integration includes a Logic and Event Link Controller (ELCL) enabling direct signal routing between peripherals (e.g., timer output triggering ADC conversion), a Data Transfer Controller (DTC) supporting chain transfer across interrupt sources, and a capacitive sensing unit (CTSU2L) supporting both self-capacitance (up to 32 keys) and mutual capacitance (8×8 matrix, up to 64 keys) configurations.
