Product details
Overview
R7F100GSL2DFB#AA0 from Renesas is a 128-pin, ultra-low-power RL78/G23 16-bit MCU with 384 KB code flash, 8 KB data flash, and 32 KB RAM, operating from 1.6–5.5 V. It integrates capacitive touch sensing (up to 64 keys), 12-bit ADC (26 channels), dual 8-bit DACs, RTC, and multiple serial interfaces including UARTA (6 ch), IICA (10 ch), and CSI (8 ch), targeting industrial HMI and sensor-edge control applications.
For engineers reviewing the R7F100GSL2DFB#AA0 datasheet, R7F100GSL2DFB#AA0 pinout, R7F100GSL2DFB#AA0 application, or R7F100GSL2DFB#AA0 equivalent, key selection criteria include its 128-pin LFQFP-0.5mm package, -40°C to +85°C industrial temperature grade, SNOOZE mode sequencer for autonomous low-power sensing, and CTSU2L-based capacitive touch support without CPU intervention.
Technical Context
The R7F100GSL2DFB#AA0 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). Its power architecture includes HALT, STOP, and SNOOZE modes - with 210 nA data retention current for 4 KB RAM and 41 µA/MHz active current - enabling battery-operated edge nodes.
Peripheral integration centers on event-driven autonomy: the Logic & Event Link Controller (ELCL) routes signals between peripherals without CPU involvement; the SNOOZE Mode Sequencer (SMS) executes up to 32 preconfigured commands (e.g., ADC sampling → comparison → GPIO toggle) while CPU, flash, and RAM remain powered down.
