Product details
Overview
R7F100GBG3CFP#AA0 from Renesas is a 48-pin LQFP-packaged RL78/G23 16-bit microcontroller with 128 KB code flash, 8 KB data flash, and 16 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 for industrial control, sensor nodes, and battery-powered HMI applications.
For engineers reviewing the R7F100GBG3CFP#AA0 datasheet, R7F100GBG3CFP#AA0 pinout, R7F100GBG3CFP#AA0 application, or R7F100GBG3CFP#AA0 equivalent, key selection criteria include its 48-pin LQFP-0.8 mm pitch package, -40°C to +105°C industrial temperature grade, and support for SNOOZE mode sequencer, RTC, and up to 26-channel 12-bit ADC - all critical for low-power embedded designs requiring deterministic wake-up and analog integration.
Technical Context
The R7F100GBG3CFP#AA0 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 hardware-assisted wake-up sources including RTC alarm, external interrupts, and CTSU2L detection events.
Peripheral integration includes a 21-command SNOOZE mode sequencer (SMS) that executes low-power background sequences without CPU, RAM, or flash activation; an ELCL for event-driven peripheral linking; and dual-domain clocking with independent high/middle/low-speed on-chip oscillators (±1.0% accuracy at 32 MHz).
