Product details
Overview
R7F100GPN2DFA#AA0 from Renesas is a 100-pin, consumer-grade RL78/G23 16-bit microcontroller with 256 KB code flash, 8 KB data flash, and 24 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 (up to 6 channels), IICA (up to 10 channels), and CSI (up to 8 channels) - deployed in battery-powered home appliances and industrial HMI panels.
For engineers reviewing the R7F100GPN2DFA#AA0 datasheet, R7F100GPN2DFA#AA0 pinout, R7F100GPN2DFA#AA0 application, or R7F100GPN2DFA#AA0 equivalent, key selection criteria include its 100-pin LFQFP (0.50-mm pitch) package, -40°C to +85°C temperature grade, SNOOZE mode sequencer for autonomous low-power sensor polling, and hardware ELCL for event-driven peripheral coordination without CPU intervention.
Technical Context
The R7F100GPN2DFA#AA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, 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 integrates a dedicated SNOOZE mode sequencer (SMS) capable of executing 32 sequential operations using 21 command types - enabling periodic analog sensing, timer-triggered wakeups, and comparator-based event handling while keeping CPU, flash, and RAM powered down.
Its peripheral set includes a Logic and Event Link Controller (ELCL) that routes signals between peripherals (e.g., ADC completion → DMA trigger → UART transmit start), a 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) configurations - all configurable via register-level control without firmware overhead.
Key Specifications

FAQ
What is the maximum operating frequency and corresponding current consumption of the R7F100GPN2DFA#AA0?
The R7F100GPN2DFA#AA0 operates up to 32 MHz using its high-speed on-chip oscillator, achieving a typical active current of 41 µA per MHz. At full speed, this equates to ~1.3 mA total active current. Its STOP mode draws just 210 nA while retaining 4 KB of RAM, and HALT mode consumes 1.2 µA - verified per R01DS0395EJ0140 Rev.1.40 datasheet Section 1.1.
Does the R7F100GPN2DFA#AA0 support hardware-based capacitive touch sensing, and how many keys can it handle?
Yes, the R7F100GPN2DFA#AA0 integrates the CTSU2L capacitive sensing unit supporting both self-capacitance (up to 32 keys on individual pins) and mutual capacitance (up to 64 keys in 8×8 matrix configuration). It includes built-in noise cancellation, automatic calibration, and programmable sensitivity - eliminating need for external touch controller ICs in designs using the R7F100GPN2DFA#AA0.
What serial communication interfaces are available on the R7F100GPN2DFA#AA0, and are they pin-multiplexed?
The R7F100GPN2DFA#AA0 provides up to 6 UARTA channels (including LIN support), 10 IICA channels, and 8 CSI channels - all implemented on multiplexed pins accessible via the Peripheral I/O Redirection Register (PIOR). This allows dynamic reassignment of functions like SDA00, RxD0, or TS01 to the same physical pin, increasing layout flexibility without requiring additional package pins.
Can the R7F100GPN2DFA#AA0 execute code while writing to data flash memory?
Yes, the R7F100GPN2DFA#AA0 supports Background Operation (BGO) for data flash memory, allowing CPU instructions to execute from code flash while data flash is being rewritten. This enables seamless firmware updates, calibration storage, and parameter logging without application interruption - with guaranteed 1,000,000 write/erase cycles per block as specified in the R7F100GPN2DFA#AA0 datasheet.
What is the purpose and capability of the SNOOZE mode sequencer (SMS) in the R7F100GPN2DFA#AA0?
The SNOOZE mode sequencer (SMS) in the R7F100GPN2DFA#AA0 executes up to 32 predefined steps using 21 command types - such as ADC conversion, value comparison, DAC output, and timer wait - entirely autonomously while CPU, flash, and RAM remain powered down. This enables ultra-low-power periodic sensing and control loops, reducing average system current by orders of magnitude compared to CPU-wakeup-based polling in the R7F100GPN2DFA#AA0.
