Product details
Overview
R7F100GEF2DNP#AA0 from Renesas is a 40-pin HWQFN-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 DAC, RTC, and multiple serial interfaces including UARTA, IICA, and CSI - deployed in battery-powered home appliances and industrial sensor nodes.
For engineers reviewing the R7F100GEF2DNP#AA0 datasheet, R7F100GEF2DNP#AA0 pinout, R7F100GEF2DNP#AA0 application, or R7F100GEF2DNP#AA0 equivalent, key selection criteria include its 40-pin HWQFN-0.5 mm pitch package, consumer-grade temperature range (−40 to +85°C), 128 KB flash/16 KB RAM memory configuration, and support for SNOOZE mode sequencer and ELCL event linking without CPU intervention.
Technical Context
The RL78/G23 core implements a CISC architecture with 3-stage pipeline and configurable instruction timing (0.03125 µs at 32 MHz high-speed mode; 30.5 µs at 32.768 kHz ultra-low-speed mode). It integrates a dedicated SNOOZE mode sequencer (SMS) supporting up to 32 sequential low-power operations using 21 command types, enabling autonomous peripheral sequencing while CPU, flash, and RAM remain powered down.
Peripheral integration includes Logic and Event Link Controller (ELCL) for hardware-level signal routing between peripherals, a 26-channel 12-bit ADC with internal 1.48 V reference and temperature sensor, dual 8-bit DACs with real-time output, and capacitive touch unit (CTSU2L) supporting self-capacitance (up to 32 keys) and mutual capacitance (8×8 matrix, up to 64 keys) under 1.8–5.5 V operation.
