Overview
R7F100GLL3CFB#AA0 from Renesas is a 64-pin LFQFP, 512-KB flash, 48-KB RAM RL78/G23 16-bit MCU operating from 1.6 to 5.5 V, featuring 41-µA/MHz active current, 210-nA data retention, capacitive touch sensing (CTSU2L), and integrated RTC, UARTA, IICA, SAU, and TAU peripherals - deployed in industrial HMI control panels requiring low-power, high-integration microcontrollers.
For engineers reviewing the R7F100GLL3CFB#AA0 datasheet, R7F100GLL3CFB#AA0 pinout, R7F100GLL3CFB#AA0 application, or R7F100GLL3CFB#AA0 equivalent, this page delivers verified electrical specs, package mapping, functional role in real-time sensor aggregation and capacitive UI control, and validated alternative options for industrial embedded design continuity.
Technical Context
The R7F100GLL3CFB#AA0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs min @ 32 MHz / 30.5 µs @ 32.768 kHz). It integrates SNOOZE mode sequencer (SMS) supporting 32 sequential low-power operations without CPU wake-up, and Logic/Event Link Controller (ELCL) enabling hardware-triggered peripheral chaining.
It features dual-clock domain operation: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable), subsystem clock (32.768 kHz), and independent voltage detectors (LVD0/LVD1). Peripheral integration includes 16-bit TAU (12 channels), 12-bit ADC (26 inputs), 8-bit DAC (2 outputs), and CTSU2L supporting up to 64 keys via mutual capacitance matrix.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GLL3CFB#AA0?
The R7F100GLL3CFB#AA0 supports up to 32 MHz operation with its high-speed on-chip oscillator, and operates across the full 1.6 V to 5.5 V supply range. At 32 MHz, minimum VDD is 2.7 V per the datasheet AC characteristics table; lower frequencies (e.g., 24 MHz) allow operation down to 1.6 V. The ±1.0% oscillator accuracy is guaranteed over -40°C to +85°C at VDD = 1.8–5.5 V.
Does the R7F100GLL3CFB#AA0 support hardware-based capacitive touch sensing, and how many keys can it manage?
Yes, the R7F100GLL3CFB#AA0 integrates the CTSU2L capacitive touch sensing unit. It supports up to 32 keys in self-capacitance mode (one pin per key) or up to 64 keys in mutual capacitance mode (8×8 matrix configuration). The unit includes hardware acceleration for baseline correction, noise filtering, and low-power scanning - eliminating need for external touch controller ICs.
Can the R7F100GLL3CFB#AA0 perform flash memory updates while executing application code?
Yes, the R7F100GLL3CFB#AA0 supports background operation (BGO) for its 8 KB data flash memory: application code continues executing from program flash while data flash is being rewritten. Additionally, it supports self-programming of code flash with boot swapping - enabling safe over-the-air firmware updates without halting real-time operation.
What debug interface does the R7F100GLL3CFB#AA0 use, and which pins are required?
The R7F100GLL3CFB#AA0 uses the on-chip debugging interface accessible via dedicated TOOL0 (pin 1), TOOLRxD (P11), and TOOLTxD (P12) pins. These three pins support full SWD-style debugging including halt/resume, register read/write, and flash programming - no external JTAG adapter required. Pin P40 (TOOL0) must be pulled high during reset to enable debug mode.
Is the R7F100GLL3CFB#AA0 qualified for industrial temperature operation, and what is its specified range?
Yes, the R7F100GLL3CFB#AA0 is qualified for industrial applications with an ambient operating temperature range of -40°C to +105°C (denoted by "3C" in the part number encoding). This rating applies to the full electrical specification including flash endurance, ADC accuracy, oscillator stability, and I/O drive strength - verified per JEDEC JESD22-A108.
