Product details
Overview
R7F100GPN2DFA#HA0 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 (up to 64 keys), and rich mixed-signal peripherals including 12-bit ADC (26 channels), dual 8-bit DACs, RTC, and multiple UART/I²C/SPI interfaces - deployed in battery-powered home appliance control units.
For engineers reviewing the R7F100GPN2DFA#HA0 datasheet, R7F100GPN2DFA#HA0 pinout, R7F100GPN2DFA#HA0 application, or R7F100GPN2DFA#HA0 equivalent, key selection criteria include its 100-pin LFQFP-0.5mm package, -40°C to +85°C temperature grade, SNOOZE mode sequencer for autonomous low-power sensor polling, and hardware event link controller (ELCL) enabling CPU-free peripheral coordination.
Technical Context
The R7F100GPN2DFA#HA0 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). Its power management includes HALT, STOP, and SNOOZE modes, with wake-up from STOP in under 4 µs.
Peripheral integration includes a 21-command SNOOZE mode sequencer (SMS) that executes up to 32 sequential operations without CPU involvement, and an Event Link Controller (ELCL) enabling direct signal routing between peripherals (e.g., ADC trigger → DTC transfer → interrupt generation) to minimize software overhead and latency.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GPL2DFA#HA0 | Same 100-pin LFQFP package and -40°C to +85°C grade, but with 192 KB code flash, 8 KB data flash, and 20 KB RAM. | Lower memory configuration suits simpler UI-only applications without complex data logging or protocol stacks. | Select when firmware size remains under 192 KB and BOM cost optimization is prioritized over future feature expansion headroom. |
| R7F100GPJ2DFA#HA0 | Same package and temperature range, with 128 KB code flash, 8 KB data flash, and 16 KB RAM; lacks some advanced peripherals (e.g., fewer UART channels). | Targeted at cost-sensitive, low-complexity control tasks such as basic motor drivers or lighting controllers with minimal connectivity. | Choose for entry-level designs where reduced peripheral count and memory footprint align with functional requirements and lower unit cost targets. |
Compared with R7F100GPL2DFA#HA0 and R7F100GPJ2DFA#HA0, the R7F100GPN2DFA#HA0 provides 64 KB more code flash and 4 KB more RAM than the former, and 128 KB more flash plus enhanced peripheral set (e.g., extra UART/I²C channels) versus the latter - making it optimal for feature-rich, field-upgradable consumer devices requiring long-term design scalability.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GPN2DFA#HA0?
The R7F100GPN2DFA#HA0 operates at up to 32 MHz using its high-speed on-chip oscillator, with guaranteed functionality across its full 1.6–5.5 V supply range. At 32 MHz, the minimum instruction execution time is 0.03125 µs. The device maintains timing specifications over the entire voltage range without requiring frequency derating, enabling single-supply designs powered directly from Li-ion batteries or unregulated wall adapters.
Does the R7F100GPN2DFA#HA0 support hardware-based capacitive touch sensing, and what configurations are available?
Yes, the R7F100GPN2DFA#HA0 integrates the CTSU2L capacitive sensing unit supporting both self-capacitance (up to 32 independent keys) and mutual capacitance (8×8 matrix, up to 64 keys). It operates from 1.8–5.5 V, includes built-in noise cancellation, and requires no external components. Electrode connections use dedicated CCD pins (e.g., P60–P62), and touch processing runs autonomously in SNOOZE mode - allowing the R7F100GPN2DFA#HA0 to detect touches while consuming only 210 nA.
How does the SNOOZE mode sequencer (SMS) in the R7F100GPN2DFA#HA0 reduce system power consumption?
The SNOOZE mode sequencer (SMS) in the R7F100GPN2DFA#HA0 executes up to 32 pre-programmed commands - such as ADC conversion, register comparison, or GPIO toggling - without waking the CPU, flash, or RAM. This allows the R7F100GPN2DFA#HA0 to perform periodic sensor polling or status checks in deep sleep, achieving sub-µA average current in duty-cycled applications. For example, a temperature read every 60 seconds consumes <0.5 µA average, versus >10 µA using conventional interrupt-driven polling.
What are the key differences between the data flash and code flash memory in the R7F100GPN2DFA#HA0?
The R7F100GPN2DFA#HA0 contains 256 KB of code flash (for program storage) and 8 KB of separate data flash (for non-volatile parameter storage). Data flash supports background operation (BGO): the R7F100GPN2DFA#HA0 can execute code from code flash while simultaneously rewriting data flash - essential for logging, calibration storage, or OTA update staging. Data flash endurance is rated at 1,000,000 write cycles (typ.), and both memories support security features like block erase prohibition.
Can the R7F100GPN2DFA#HA0 interface directly with I²C sensors and RS-485 transceivers, and what hardware support is provided?
Yes, the R7F100GPN2DFA#HA0 includes up to 10 hardware I²C channels (IICA) supporting standard/fast-mode speeds and automatic clock stretching, enabling direct connection to temperature, humidity, or IMU sensors. For RS-485, it uses UARTA channels with software-controlled direction pin handling; the R7F100GPN2DFA#HA0's 100-pin package provides dedicated GPIOs (e.g., P16/P17) for DE/RE control, and its 5.5 V-tolerant I/Os simplify level-shifting circuitry. Hardware CRC generation accelerates Modbus frame integrity checks.
