Product details
Overview
R7F100GLJ2DFB#BA0 from Renesas is a 64-pin LFQFP, 512-KB flash, 32-KB RAM RL78/G23 16-bit microcontroller operating from 1.6–5.5 V, featuring 210-nA data retention current, 41-µA/MHz active current, and integrated capacitive touch sensing (CTSU2L) for low-power HMI applications in industrial control panels and sensor nodes.
For engineers reviewing the R7F100GLJ2DFB#BA0 datasheet, R7F100GLJ2DFB#BA0 pinout, R7F100GLJ2DFB#BA0 application, or R7F100GLJ2DFB#BA0 equivalent, key selection criteria include its 64-pin LFQFP-0.50mm package, -40°C to +85°C temperature grade (D-field), 256-KB code flash variant within the RL78/G23 family, and support for SNOOZE mode sequencer for autonomous peripheral operation without CPU wake-up.
Technical Context
The R7F100GLJ2DFB#BA0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs min @ 32 MHz high-speed oscillator or 30.5 µs @ 32.768 kHz subsystem clock). It integrates a 21-command SNOOZE mode sequencer (SMS) enabling up to 32 sequential low-power operations independent of CPU, flash, or RAM.
Peripheral integration includes dual 16-bit timer arrays (TAU) with 16 channels total, 8–26-channel 8/10/12-bit ADC with internal 1.48-V reference and temperature sensor, two 8-bit DAC outputs (0–VDD), and logic/event link controller (ELCL) for configurable signal routing between peripherals without CPU intervention.
