It integrates capacitive touch sensing (CTSU2L), 12-bit ADC (26 channels), dual DAC, RTC, and multiple serial interfaces for embedded control in battery-powered industrial sensors and HMI panels.
For engineers reviewing the R7F100GFL2DFP#AA0 datasheet, R7F100GFL2DFP#AA0 pinout, R7F100GFL2DFP#AA0 application, or R7F100GFL2DFP#AA0 equivalent, key selection criteria include its 44-pin LQFP-0.8 mm pitch package, 256 KB flash/24 KB RAM memory configuration, CTSU2L-based touch interface support, and verified STOP-mode current of 210 nA with 4 KB RAM retention.
Technical Context
The R7F100GFL2DFP#AA0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs min @ 32 MHz high-speed oscillator or 30.5 µs @ 32.768 kHz subsystem clock). It supports SNOOZE mode sequencer (SMS) with 32 programmable processes and 21 command types for autonomous low-power peripheral sequencing without CPU wake-up.
Its peripheral set includes Logic and Event Link Controller (ELCL) for configurable signal routing between peripherals, Data Transfer Controller (DTC) with chain transfer, and dual-voltage I/O (1.8/2.5/3.0 V compatible) with N-ch open-drain and controlled-current drive options - enabling direct interfacing with mixed-voltage sensor and display subsystems.

FAQ
What is the maximum operating frequency and minimum instruction cycle time for the R7F100GFL2DFP#AA0?
The R7F100GFL2DFP#AA0 supports a maximum CPU clock of 32 MHz using the high-speed on-chip oscillator. At this frequency, the minimum instruction execution time is 0.03125 µs. The device also supports ultra-low-speed operation at 32.768 kHz (subsystem clock), where the minimum instruction time extends to 30.5 µs - enabling precise trade-offs between performance and power consumption.
Does the R7F100GFL2DFP#AA0 support hardware-accelerated capacitive touch sensing, and how many electrodes can it handle?
Yes, the R7F100GFL2DFP#AA0 integrates the CTSU2L (Capacitive Touch Sensing Unit Level 2) with dedicated hardware for self-capacitance (up to 32 keys on single pins) and mutual-capacitance (8×8 matrix, up to 64 keys). It includes automatic drift compensation, noise rejection filters, and programmable scan timing - eliminating need for external touch controller ICs or host-CPU polling overhead.
What are the supported low-power modes of the R7F100GFL2DFP#AA0, and what is the typical current draw in STOP mode with RAM retention?
The R7F100GFL2DFP#AA0 supports HALT, STOP, and SNOOZE modes. In STOP mode with 4 KB of RAM retained, the typical current draw is 210 nA at VDD = 3.0 V and TA = 25°C. This mode disables the CPU, flash, and most peripherals while maintaining RTC operation and wake-up capability via external interrupts or RTC alarm - ideal for multi-year battery applications.
Can the R7F100GFL2DFP#AA0 perform background data flash rewriting while executing code from main flash memory?
Yes, the R7F100GFL2DFP#AA0 supports Background Operation (BGO) for data flash memory. Instructions can be fetched and executed from code flash while data flash is being rewritten, enabling seamless firmware parameter updates or data logging without system interruption. The data flash size is fixed at 8 KB across all RL78/G23 variants, including the R7F100GFL2DFP#AA0.
What serial communication interfaces are available on the R7F100GFL2DFP#AA0, and which support LIN bus protocol?
The R7F100GFL2DFP#AA0 provides up to 6 UARTA channels, all of which support LIN bus protocol (LIN 2.2A compliant). It also includes up to 10 I²C/Simplified I²C channels, up to 8 CSI (SPI-compatible) channels, and 1 Remote Control Signal Receiver (REMC) channel. All UARTA instances share common baud rate generators and LIN-specific features like auto-sync break detection and checksum calculation.
