Product details
Overview
R7F100GPJ2DFA#AA0 from Renesas is a 100-pin, consumer-grade RL78/G23 16-bit MCU 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 rich peripherals including 16-bit timers, 12-bit ADC (26 channels), dual DAC, RTC, and multiple UART/I²C/SPI interfaces - deployed in battery-powered home appliances and smart sensors.
For engineers reviewing the R7F100GPJ2DFA#AA0 datasheet, R7F100GPJ2DFA#AA0 pinout, R7F100GPJ2DFA#AA0 application, or R7F100GPJ2DFA#AA0 equivalent, key selection criteria include its 100-pin LFQFP (0.50-mm pitch) package, -40°C to +85°C temperature grade, 256 KB flash capacity, SNOOZE mode sequencer for autonomous low-power sensing, and hardware ELCL for event-driven peripheral coordination without CPU intervention.
Technical Context
The R7F100GPJ2DFA#AA0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting configurable instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode). Its SNOOZE mode sequencer (SMS) executes up to 32 preconfigured commands-including comparisons and calculations-without waking the CPU, flash, or RAM, enabling deterministic low-power sensor polling.
Peripheral integration includes a Logic and Event Link Controller (ELCL) that routes and combines event signals between peripherals (e.g., timer overflow → ADC trigger → DMA transfer), plus a Data Transfer Controller (DTC) supporting chain transfers across memory and registers. The capacitive sensing unit (CTSU2L) supports both self- and mutual-capacitance methods, with dedicated hardware for noise immunity and automatic calibration.
