Product details
Overview
R7F100GGK2DFB#AA0 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), integrated capacitive touch sensing (up to 64 keys), and supports industrial temperature range (−40 to +105°C) for embedded control in battery-powered HMI and sensor interface applications.
For engineers reviewing the R7F100GGK2DFB#AA0 datasheet, R7F100GGK2DFB#AA0 pinout, R7F100GGK2DFB#AA0 application, or R7F100GGK2DFB#AA0 equivalent, key selection criteria include its 48-pin LFQFP-0.5 mm pitch package, 256 KB flash/24 KB RAM memory configuration, SNOOZE mode sequencer for autonomous low-power operation, and dual-voltage I/O support enabling direct interfacing with 1.8/2.5/3.0 V peripherals.
Technical Context
The RL78/G23 core implements a CISC architecture with 3-stage pipeline and 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 commands across 21 instruction types, enabling CPU-free periodic sensing and processing without RAM/flash activation.
Peripheral integration includes up to 26-channel 8/10/12-bit ADC with internal 1.48 V reference and temperature sensor, dual 8-bit DACs with real-time output, two comparators with selectable internal/external reference, and flexible serial interfaces: up to 10 I²C/Simplified I²C channels, 6 UARTA/LIN-capable channels, and 8 CSI (SPI-compatible) channels-all configurable via peripheral I/O redirection register (PIOR).
