Product details
Overview
R7F100GSN3CFB#HA0 from Renesas is a 128-pin, industrial-grade RL78/G23 16-bit MCU with 768 KB code flash, 48 KB RAM, and 8 KB data flash, 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 real-time clock, 16-bit timers, 12-bit ADC (26 channels), and multiple serial interfaces - deployed in battery-powered industrial HMI and sensor node applications.
For engineers reviewing the R7F100GSN3CFB#HA0 datasheet, R7F100GSN3CFB#HA0 pinout, R7F100GSN3CFB#HA0 application, or R7F100GSN3CFB#HA0 equivalent, key selection criteria include its LFQFP-128 (0.50-mm pitch) package, -40°C to +105°C industrial temperature rating, SNOOZE mode sequencer for autonomous low-power sensing, and hardware ELCL for event-driven peripheral coordination without CPU intervention.
Technical Context
The R7F100GSN3CFB#HA0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting configurable instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode). Its power management includes HALT, STOP, and SNOOZE modes, with wake-up from STOP in under 4 µs.
Peripheral integration includes a 21-command SNOOZE mode sequencer (SMS) that executes up to 32 sequential processes autonomously, an Event Link Controller (ELCL) enabling direct hardware-level signal routing between peripherals, and a capacitive touch unit (CTSU2L) supporting both self- and mutual-capacitance configurations for robust touch interface design.
