Product details
Overview
R7F100GJL3CFA#AA0 from Renesas is a 52-pin, industrial-grade RL78/G23 16-bit microcontroller with 256 KB code flash, 8 KB data flash, and 24 KB RAM, operating from 1.6–5.5 V. It integrates capacitive touch sensing (CTSU2L), 16-bit TAU timers (up to 16 channels), 12-bit ADC (24 channels), UARTA/LIN, IICA, and SNOOZE mode sequencer for ultra-low-power sensor interface applications.
For engineers reviewing the R7F100GJL3CFA#AA0 datasheet, R7F100GJL3CFA#AA0 pinout, R7F100GJL3CFA#AA0 application, or R7F100GJL3CFA#AA0 equivalent, key selection criteria include its 52-pin LQFP-0.65mm package, -40°C to +105°C industrial temperature rating, 210-nA data retention current, and integrated CTSU2L supporting up to 64-key mutual-capacitance touch panels.
Technical Context
The RL78/G23 core implements a 3-stage pipeline CISC architecture with configurable instruction timing (0.03125 µs at 32 MHz high-speed mode or 30.5 µs at 32.768 kHz ultra-low-speed mode) and supports multiply/divide/accumulate instructions. Its SNOOZE mode sequencer executes up to 32 low-power processes without CPU, RAM, or flash activation using 21 built-in commands.
Peripheral integration includes a Logic and Event Link Controller (ELCL) enabling hardware-triggered signal routing between peripherals, a Data Transfer Controller (DTC) supporting chain transfers, and dual-voltage detectors (LVD0/LVD1) for robust power monitoring across the 1.6–5.5 V supply range.
