Product details
Overview
R7F100GGL3CFB#AA0 from Renesas is a 48-pin LFQFP-packaged RL78/G23 16-bit microcontroller with 384 KB code flash, 8 KB data flash, and 32 KB RAM, operating at 1.6–5.5 V and -40 to +105°C for industrial applications. It integrates capacitive touch sensing (CTSU2L), 12-bit ADC (26 channels), dual DAC, RTC, UARTA/IICA/SAU interfaces, and ultra-low-power STOP/SNOOZE modes enabling battery-powered HMI and sensor control.
For engineers reviewing the R7F100GGL3CFB#AA0 datasheet, R7F100GGL3CFB#AA0 pinout, R7F100GGL3CFB#AA0 application, or R7F100GGL3CFB#AA0 equivalent, key selection criteria include its 48-pin LFQFP-0.5 mm pitch package, industrial temperature grade (3C), CTSU2L support for up to 64 keys in mutual-capacitance mode, and SNOOZE mode sequencer for autonomous low-power peripheral sequencing without CPU wake-up.
Technical Context
The R7F100GGL3CFB#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 SNOOZE mode sequencer executes up to 32 preconfigured commands-including ADC sampling, comparator comparison, and timer counting-using dedicated hardware, eliminating CPU involvement during low-power monitoring cycles.
Peripheral integration includes a Logic and Event Link Controller (ELCL) enabling direct signal routing between peripherals (e.g., ADC trigger → timer → interrupt), and a Data Transfer Controller (DTC) supporting chain transfers across UART, IICA, and SAU without CPU overhead. The CTSU2L unit operates natively at VDD = 1.8–5.5 V, supporting both self-capacitance (32-key single-pin) and mutual-capacitance (8×8 matrix) configurations.
