Product details
Overview
R7F100GPG2DFA#AA0 from Renesas is a 100-pin, consumer-grade 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 (CTSU2L), 12-bit ADC (26 channels), dual DAC, RTC, and multiple serial interfaces including UARTA (up to 6 channels), IICA (up to 10 channels), and CSI (up to 8 channels) - deployed in battery-powered home appliance control panels.
For engineers reviewing the R7F100GPG2DFA#AA0 datasheet, R7F100GPG2DFA#AA0 pinout, R7F100GPG2DFA#AA0 application, or R7F100GPG2DFA#AA0 equivalent, key selection criteria include its 100-pin LFQFP (0.5 mm pitch) package, -40°C to +85°C temperature grade, SNOOZE mode sequencer for autonomous low-power sensor polling, and hardware event link controller (ELCL) enabling interrupt-free peripheral coordination.
Technical Context
The RL78/G23 core implements a CISC architecture with 3-stage pipeline and configurable instruction timing (0.03125 µs min @ 32 MHz high-speed oscillator or 30.5 µs @ 32.768 kHz subsystem clock). It supports multiply/divide/accumulate instructions and features a 1 MB address space with four banks of eight 8-bit general-purpose registers.
Power management includes HALT, STOP, and SNOOZE modes; the latter uses a dedicated sequencer executing up to 32 preconfigured commands (from 21 available) without CPU, flash, or RAM activation. Peripheral coordination is handled by the Event Link Controller (ELCL), which routes signals between peripherals via programmable logic and flip-flop circuits.
