Product details
Overview
R7F100GGF2DFB#BA0 from Renesas is a 48-pin 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), 16-bit TAU timers, RTC, and dual UART/I²C/SPI interfaces - deployed in battery-powered industrial HMI and sensor nodes.
For engineers reviewing the R7F100GGF2DFB#BA0 datasheet, R7F100GGF2DFB#BA0 pinout, R7F100GGF2DFB#BA0 application, or R7F100GGF2DFB#BA0 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, and support for SNOOZE mode sequencer and ELCL event linking without CPU intervention.
Technical Context
The RL78/G23 core implements a 3-stage pipeline CISC architecture with configurable instruction timing (0.03125 µs min @ 32 MHz high-speed oscillator or 30.5 µs @ 32.768 kHz subsystem clock). It integrates a SNOOZE mode sequencer (SMS) supporting up to 32 sequential low-power operations using 21 command types, enabling autonomous peripheral sequencing without RAM/CPU/flash activation.
Peripheral integration includes Logic and Event Link Controller (ELCL) for hardware-triggered signal routing between peripherals, capacitive touch unit (CTSU2L) supporting self-capacitance (32 keys) or mutual capacitance (8×8 matrix), and dual serial array units (SAU) with UART/LIN, I²C, and CSI (SPI-compatible) channels - all accessible via multiplexed I/O with PIOR-based redirection.

FAQ
What is the maximum operating frequency and voltage range supported by the R7F100GGF2DFB#BA0?
The R7F100GGF2DFB#BA0 operates at up to 32 MHz using its high-speed on-chip oscillator and supports a wide supply voltage range of 1.6 V to 5.5 V. Its ±1.0% oscillator accuracy over –20°C to +85°C eliminates the need for external crystals in UART/LIN timing-critical applications, and the 1.6 V minimum VDD enables direct operation from single-cell lithium or alkaline batteries.
Does the R7F100GGF2DFB#BA0 support capacitive touch sensing, and how many keys can it handle?
Yes, the R7F100GGF2DFB#BA0 integrates the CTSU2L capacitive touch sensing unit supporting up to 32 self-capacitance keys (single-pin per key) or 64 mutual-capacitance keys (8×8 matrix). It includes built-in noise cancellation and auto-calibration features, allowing robust touch detection even in electrically noisy industrial environments without external RC components or shielding.
What low-power modes are available on the R7F100GGF2DFB#BA0, and what is the lowest current draw?
The R7F100GGF2DFB#BA0 offers HALT, STOP, and SNOOZE modes. In STOP mode with RAM retention, it draws 210 nA; in HALT mode, current drops to 0.32 µA. The SNOOZE mode sequencer enables autonomous peripheral operation (e.g., ADC sampling → compare → GPIO toggle) without CPU wake-up - achieving sub-µA average current in sensor polling applications.
Can the R7F100GGF2DFB#BA0 perform background data flash writes while executing code from program flash?
Yes, the R7F100GGF2DFB#BA0 supports Background Operation (BGO) for data flash, allowing instruction execution from code flash memory while simultaneously rewriting the 8 KB data flash. This capability enables seamless firmware updates, parameter storage, and field calibration without halting real-time tasks - critical for industrial systems requiring zero-downtime operation.
What communication interfaces are integrated into the R7F100GGF2DFB#BA0, and how many instances does each support?
The R7F100GGF2DFB#BA0 integrates up to 6 UART/LIN channels, 10 I²C/Simplified I²C channels, and 8 CSI (SPI-compatible) channels. These are distributed across two Serial Array Units (SAU0/SAU1), with flexible pin multiplexing via the Peripheral I/O Redirection Register (PIOR) - enabling concurrent use of multiple protocols (e.g., UART to host, I²C to sensor, SPI to display) on a single 48-pin footprint.
