Product details
Overview
R7F100GPL2DFA#HA0 from Renesas is a 100-pin LFQFP-packaged RL78/G23 16-bit microcontroller with 512 KB code flash, 48 KB RAM, and 8 KB data flash, operating from 1.6–5.5 V. It delivers true low-power operation (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (CTSU2L), and dual-clock domain support for ultra-low-power wake-up from STOP mode in consumer-grade applications (−40 to +85°C).
For engineers reviewing the R7F100GPL2DFA#HA0 datasheet, R7F100GPL2DFA#HA0 pinout, R7F100GPL2DFA#HA0 application, or R7F100GPL2DFA#HA0 equivalent, this device serves as a drop-in-capable upgrade path from RL78/G13/G14 with enhanced peripheral integration including SNOOZE mode sequencer, ELCL event routing, and hardware-accelerated background data flash rewriting.
Technical Context
The R7F100GPL2DFA#HA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed oscillator) to 30.5 µs (32.768 kHz subsystem clock). Its memory subsystem includes 512 KB code flash (2 KB block size, security-locked erase/write), 48 KB SRAM, and 8 KB data flash with background operation (BGO) enabling concurrent program execution during rewrites.
Peripherals include 16-bit TAU timers (16 channels), RTC with alarm/correction, 12-bit ADC (26 channels), 8-bit DAC (2 channels), 2 comparators, 10-channel I²C/Simplified I²C, 6-channel UARTA (LIN-capable), 8-channel CSI, remote control receiver, and CTSU2L capacitive sensing unit supporting up to 64 keys via mutual capacitance matrix.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GPK2DFA#HA0 | Same package and pinout; reduced memory (384 KB code flash, 32 KB RAM). | Targeted at cost-sensitive designs with smaller firmware footprint and fewer concurrent tasks. | Select when application firmware fits within 384 KB and RAM usage remains ≤32 KB-reduces BOM cost without layout change. |
| R7F100GPL3CFA#HA0 | Identical memory and peripherals; industrial-grade temperature range (−40 to +105°C) and different packaging specification (#HA0 vs #HA0 same, but field code 'C' instead of 'D'). | Required for factory automation, motor drives, or automotive cabin modules where extended ambient temperature tolerance is mandatory. | Choose for industrial environments exceeding +85°C ambient; no hardware redesign needed-only qualification and sourcing adjustment. |
Compared with R7F100GPK2DFA#HA0, the R7F100GPL2DFA#HA0 provides 128 KB additional code flash and 16 KB more RAM for feature-rich firmware and larger data buffers; versus R7F100GPL3CFA#HA0, it trades industrial temperature rating for lower cost and consumer-grade qualification-ideal for high-volume white goods and portable electronics.

FAQ
What is the maximum operating frequency of the R7F100GPL2DFA#HA0?
The R7F100GPL2DFA#HA0 supports a maximum system clock frequency of 32 MHz using the high-speed on-chip oscillator. This enables a minimum instruction execution time of 0.03125 µs. The device also supports lower-frequency clock sources-including 32.768 kHz for RTC-to optimize power consumption based on real-time requirements. All timing specifications are guaranteed across the full −40 to +85°C operating range.
Does the R7F100GPL2DFA#HA0 support in-system programming (ISP) and debugging?
Yes, the R7F100GPL2DFA#HA0 includes full on-chip debugging capability via the single-wire debug interface (SWD), compatible with Renesas E2 studio and CS+ IDEs. It supports ISP through the built-in bootloader and self-programming features-including boot swapping and flash shield window protection-enabling secure field firmware updates without external programmers.
How many capacitive touch channels does the R7F100GPL2DFA#HA0 support?
The R7F100GPL2DFA#HA0 integrates the CTSU2L capacitive sensing unit, supporting up to 32 self-capacitance channels (one per pin) or 64 mutual-capacitance channels (8 × 8 matrix). Pin assignments for touch sensing are fixed per the 100-pin LFQFP pinout-P30 (TSCAP), P31 (TS01), and additional ports like P20–P25 and P70–P73 are configurable as CTSU electrodes depending on application layout.
What are the key low-power modes supported by the R7F100GPL2DFA#HA0?
The R7F100GPL2DFA#HA0 offers HALT, STOP, and SNOOZE modes. STOP mode achieves 210 nA data retention current with full 48 KB RAM retention. SNOOZE mode enables autonomous peripheral sequencing (e.g., ADC sampling → compare → GPIO toggle) without CPU involvement-reducing average system current to sub-µA levels in sensor polling applications. Wake-up from STOP is under 3.5 µs.
Is the R7F100GPL2DFA#HA0 pin-compatible with other RL78/G23 variants in the same package?
Yes, all RL78/G23 devices in the 100-pin LFQFP package-including R7F100GPK2DFA#HA0, R7F100GPL2DFA#HA0, and R7F100GPN2DFA#HA0-share identical pinouts and electrical characteristics. Memory size, temperature grade, and field code differ, but PCB layout, decoupling, and signal routing remain fully interchangeable across this package family.
