Product details
Overview
R7F100GBJ2DFP#BA0 from Renesas is a 32-bit RL78/G23 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), integrated capacitive touch sensing (CTSU2L), and supports industrial temperature range (−40 to +85°C) in a 32-pin LQFP package for embedded control in battery-powered sensor nodes and smart appliances.
For engineers reviewing the R7F100GBJ2DFP#BA0 datasheet, R7F100GBJ2DFP#BA0 pinout, R7F100GBJ2DFP#BA0 application, or R7F100GBJ2DFP#BA0 equivalent, key selection criteria include its 256 KB flash/24 KB RAM balance, CTSU2L support for self- and mutual-capacitance touch up to 64 keys, SNOOZE mode sequencer for autonomous low-power sensing, and dual UARTA + IICA + CSI interfaces for multi-protocol connectivity.
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 on-chip oscillator ±1.0%) or 30.5 µs at 32.768 kHz (subsystem clock). It integrates a SNOOZE mode sequencer (SMS) supporting 32 sequential operations using 21 command types, enabling CPU-free periodic sensing without RAM/flash activation.
Peripheral integration includes a 12-bit A/D converter (up to 26 channels), dual 8-bit D/A outputs (0–VDD), two comparators with selectable internal/external reference, and an Event Link Controller (ELCL) that routes signals between peripherals via programmable logic and flip-flops-enabling hardware-triggered event chains without CPU intervention.
