Overview
R7F100GGL3CNP#AA0 from Renesas is a 48-pin HWQFN-packaged RL78/G23 16-bit microcontroller with 384 KB code flash, 8 KB data flash, and 32 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 industrial HMI and sensor node applications.
For engineers reviewing the R7F100GGL3CNP#AA0 datasheet, R7F100GGL3CNP#AA0 pinout, R7F100GGL3CNP#AA0 application, or R7F100GGL3CNP#AA0 equivalent, key selection criteria include its 48-pin HWQFN-0.5 mm pitch package, 384 KB flash/32 KB RAM memory configuration, C-grade industrial temperature range (−40 to +105°C), and support for SNOOZE mode sequencer, ELCL event linking, and hardware CRC.
Technical Context
The R7F100GGL3CNP#AA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, enabling configurable instruction execution time from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). It integrates a dedicated SNOOZE mode sequencer (SMS) that executes up to 32 low-power processes without CPU, RAM, or flash activation, using 21 command types for autonomous sensor polling and threshold comparison.
Peripherals include a 10-channel I²C/Simplified I²C interface, 6-channel UARTA with LIN support, 8-channel 16-bit TAU timer, 26-channel 12-bit ADC with internal 1.48 V reference and temperature sensor, and a 2-channel 8-bit DAC with real-time output capability - all accessible via multiplexed pins on the 48-pin HWQFN footprint.
