Product details
Overview
R7F100GGH2DFB#BA0 from Renesas is a 48-pin LFQFP, 128-KB flash, 16-KB RAM RL78/G23 16-bit microcontroller operating at 1.6–5.5 V, featuring 26-channel 12-bit ADC, capacitive touch sensing (CTSU2L), and ultra-low-power STOP mode (210 nA data retention). It targets battery-powered industrial HMI and sensor nodes requiring deterministic real-time control with integrated analog peripherals.
For engineers reviewing the R7F100GGH2DFB#BA0 datasheet, R7F100GGH2DFB#BA0 pinout, R7F100GGH2DFB#BA0 application, or R7F100GGH2DFB#BA0 equivalent, this page delivers verified package mapping, validated SNOOZE mode sequencer behavior, confirmed CTSU2L self/mutual capacitance support, and precise peripheral I/O redirection register (PIOR) capability for flexible signal routing in space-constrained designs.
Technical Context
The R7F100GGH2DFB#BA0 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz high-speed oscillator) to 30.5 µs (32.768 kHz subsystem clock). Its SNOOZE mode sequencer executes up to 32 preconfigured commands-including ADC sampling, comparator comparison, and timer-triggered wakeups-without CPU, RAM, or flash activation.
Peripheral integration includes dual UARTA channels (one LIN-capable), four IICA interfaces, six SAU channels, and a logic/event link controller (ELCL) enabling hardware-level event chaining between timers, ADC, and communication modules-eliminating software overhead for time-critical signal coordination.
