Product details
Overview
R7F100GPN3CFA#HA0 from Renesas is a 100-pin, industrial-grade RL78/G23 16-bit MCU with 192 KB code flash, 8 KB data flash, and 20 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 dual-clock domain operation supporting high-speed (32 MHz) and ultra-low-speed (32.768 kHz) modes for battery-powered HMI and sensor control applications.
For engineers reviewing the R7F100GPN3CFA#HA0 datasheet, R7F100GPN3CFA#HA0 pinout, R7F100GPN3CFA#HA0 application, or R7F100GPN3CFA#HA0 equivalent, this page provides verified technical context, package mapping to LQFP-100 (0.65-mm pitch), confirmed SNOOZE mode sequencer operation, ELCL event linking, and real-world design values for RTC, ADC, and UARTA interfaces.
Technical Context
The R7F100GPN3CFA#HA0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling configurable instruction execution time from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). Its dual-clock system isolates subsystem timing: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) drives core/peripherals, while low-speed 32.768-kHz oscillator powers RTC and STOP-mode wake-up.
Peripheral integration includes a 21-command SNOOZE mode sequencer (SMS) that executes up to 32 sequential operations without CPU, RAM, or flash activation; an Event Link Controller (ELCL) enabling hardware-level signal routing between peripherals; and a 10-channel I²C/Simplified I²C interface with clock stretching support-critical for deterministic sensor bus arbitration in industrial control loops.
