Product details
Overview
R7F100GFH3CFP#AA0 from Renesas is a 44-pin LQFP-packaged RL78/G23 16-bit MCU with 128 KB code flash, 8 KB data flash, and 16 KB RAM, operating from 1.6–5.5 V at -40 to +85°C industrial temperature range. It integrates capacitive touch sensing (CTSU2L), 12-bit ADC (26 channels), dual 8-bit DACs, RTC, and low-power STOP/SNOOZE modes for battery-powered HMI and sensor interface applications.
For engineers reviewing the R7F100GFH3CFP#AA0 datasheet, R7F100GFH3CFP#AA0 pinout, R7F100GFH3CFP#AA0 application, or R7F100GFH3CFP#AA0 equivalent, key selection criteria include its 44-pin LQFP-0.8 mm pitch package, 128-KB flash capacity, CTSU2L support for up to 64 keys in mutual-capacitance mode, and verified SNOOZE mode sequencer operation without CPU wake-up.
Technical Context
The R7F100GFH3CFP#AA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, 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 predefined commands-including ADC sampling, comparator comparison, and CTSU measurement-without CPU, RAM, or flash activation.
Peripheral integration includes 4-channel I²C/Simplified I²C, 3–6 UARTA channels (LIN-bus supported), 3–8 CSI/SPI channels, and an ELCL enabling event-driven signal routing between peripherals like timers, ADC, and CTSU-enabling deterministic low-latency response in real-time control loops.
