Product details
Overview
R7F100GLJ2DFA#AA0 from Renesas is a 64-pin, consumer-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 delivers ultra-low power consumption (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (up to 64 keys), and dual 16-bit timer arrays - deployed in battery-powered home appliances and smart sensors.
For engineers reviewing the R7F100GLJ2DFA#AA0 datasheet, R7F100GLJ2DFA#AA0 pinout, R7F100GLJ2DFA#AA0 application, or R7F100GLJ2DFA#AA0 equivalent, key selection criteria include its 64-pin LQFP-0.65mm package, -40°C to +85°C temperature grade, SNOOZE mode sequencer for autonomous low-power sensing, and hardware-based event link controller for interrupt-free peripheral coordination.
Technical Context
The R7F100GLJ2DFA#AA0 implements the RL78 CPU core with a 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, comparison, and conditional branching-without CPU, RAM, or flash activation.
Peripheral integration includes a 21-function ELCL for configurable event routing between timers, ADC, UART, and CTSU; dual 16-bit timer arrays (TAU) with 16 channels total; and a 10-bit A/D converter with 26 input channels, internal 1.48 V reference, and temperature sensor.
