Product details
Overview
R7F100GPH2DFB#AA0 from Renesas is a 100-pin, 5.0-mm-pitch LFQFP-packaged RL78/G23 16-bit microcontroller with 128 KB code flash, 8 KB data flash, and 16 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 (CTSU2L), 12-bit ADC (26 channels), dual 8-bit DACs, RTC, and multiple serial interfaces including UARTA (up to 6 channels), IICA (up to 10 channels), and CSI (up to 8 channels) for industrial HMI and sensor node applications.
For engineers reviewing the R7F100GPH2DFB#AA0 datasheet, R7F100GPH2DFB#AA0 pinout, R7F100GPH2DFB#AA0 application, or R7F100GPH2DFB#AA0 equivalent, key selection criteria include its 100-pin LFQFP-0.50mm package, -40°C to +85°C industrial temperature grade (D-field), 128 KB flash/16 KB RAM memory configuration, CTSU2L capacitive sensing support, and SNOOZE mode sequencer for autonomous low-power peripheral operation without CPU wake-up.
Technical Context
The R7F100GPH2DFB#AA0 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode). Its power management includes HALT, STOP, and SNOOZE modes, with STOP mode wakeup in under 4 µs and SNOOZE sequencer enabling up to 32 autonomous operations using 21 command types without CPU involvement.
Peripheral integration includes a Logic and Event Link Controller (ELCL) for configurable event routing between peripherals, Data Transfer Controller (DTC) with chain transfer capability, and a Remote Control Signal Receiver supporting four waveform pattern matches (header, data 0/1, special data) - all operating independently of CPU execution during low-power states.
