Product details
Overview
R7F100GGF2DFB#AA0 from Renesas is a 48-pin LFQFP-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. It delivers ultra-low power consumption (41 µA/MHz active, 210 nA data retention), integrates capacitive touch sensing (up to 64 keys), 12-bit ADC (26 channels), dual 8-bit DACs, RTC, and multiple serial interfaces including UART, I²C, and simplified SPI - deployed in battery-powered industrial HMI and sensor nodes.
For engineers reviewing the R7F100GGF2DFB#AA0 datasheet, R7F100GGF2DFB#AA0 pinout, R7F100GGF2DFB#AA0 application, or R7F100GGF2DFB#AA0 equivalent, key selection criteria include its 48-pin LFQFP-0.5 mm pitch package, -40°C to +85°C consumer-grade temperature range, 128 KB flash/16 KB RAM memory configuration, integrated CTSU2L capacitive sensing unit, and support for SNOOZE mode sequencer for autonomous low-power peripheral operation without CPU wake-up.
Technical Context
The R7F100GGF2DFB#AA0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode). It features a dedicated SNOOZE mode sequencer (SMS) capable of executing up to 32 sequential operations using 21 command types - enabling autonomous analog monitoring, timer sequencing, and event-triggered responses without CPU involvement.
Peripheral integration includes a Logic and Event Link Controller (ELCL) for configurable signal routing between peripherals, Data Transfer Controller (DTC) with chain transfer support, and a capacitive sensing unit (CTSU2L) supporting both self-capacitance (32 keys) and mutual capacitance (8×8 matrix, 64 keys) modes under 1.8–5.5 V operation. All peripherals are clocked via selectable on-chip oscillators: high-speed (±1.0% accuracy, 1–32 MHz), middle-speed (adjustable 1–4 MHz), and low-speed (32.768 kHz).

FAQ
What is the maximum operating frequency and accuracy of the on-chip oscillator for R7F100GGF2DFB#AA0?
The R7F100GGF2DFB#AA0 supports a high-speed on-chip oscillator selectable from 1 MHz to 32 MHz with ±1.0% accuracy across VDD = 1.8–5.5 V and TA = −20°C to +85°C. This oscillator serves as the primary system clock source and enables precise timing for UART, I²C, and PWM functions without external crystals.
Does R7F100GGF2DFB#AA0 support capacitive touch sensing, and what configurations are available?
Yes, R7F100GGF2DFB#AA0 integrates the CTSU2L capacitive sensing unit supporting both self-capacitance (up to 32 keys on single pins) and mutual capacitance (8×8 matrix, up to 64 keys) modes. It operates from 1.8 V to 5.5 V and requires no external components - ideal for ruggedized touch panels in industrial environments.
What power modes does R7F100GGF2DFB#AA0 support, and how low is the standby current?
R7F100GGF2DFB#AA0 supports HALT, STOP, and SNOOZE modes. In STOP mode with 4 KB RAM retention, current drops to 210 nA. Full 16 KB RAM retention is supported at slightly higher current. The SNOOZE mode sequencer enables peripheral-driven operation (e.g., ADC sampling, comparisons) without waking the CPU or flash, further reducing average system power.
How many serial communication interfaces does R7F100GGF2DFB#AA0 include, and which protocols are supported?
R7F100GGF2DFB#AA0 includes up to 6 UARTA channels (with LIN bus support), up to 10 I²C/Simplified I²C channels, and up to 8 simplified SPI (CSI) channels. These interfaces support simultaneous operation - for example, UARTA for host communication, I²C for sensor reading, and CSI for display driver control - all managed by the DTC and ELCL for minimal CPU load.
Is R7F100GGF2DFB#AA0 pin-compatible with other RL78/G23 variants in the 48-pin LFQFP package?
Yes, all RL78/G23 devices in the 48-pin LFQFP package (FB suffix) share identical pinouts and electrical characteristics, including R7F100GGF2DFB#AA0, R7F100GGL2DFB#AA0, and R7F100GFH2DFB#AA0.
