Product details
Overview
R7F100GLF2DFA#HA0 from Renesas is a 64-pin, consumer-grade RL78/G23 16-bit MCU with 512 KB code flash, 8 KB data flash, and 48 KB RAM, 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 (up to 64 keys), and rich peripherals including 16-bit timers, 12-bit ADC (26 channels), dual DAC, RTC, and multiple UART/I²C/SPI interfaces - deployed in battery-powered home appliances and industrial HMI panels.
For engineers reviewing the R7F100GLF2DFA#HA0 datasheet, R7F100GLF2DFA#HA0 pinout, R7F100GLF2DFA#HA0 application, or R7F100GLF2DFA#HA0 equivalent, key selection considerations include its LFQFP-64 (0.5 mm pitch) package, -40°C to +85°C temperature grade, SNOOZE mode sequencer for ultra-low-power sensor polling, and hardware ELCL for event-driven peripheral coordination without CPU intervention.
Technical Context
The R7F100GLF2DFA#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 - the latter enabling autonomous 32-step sequenced operations using 21 command types while keeping CPU, flash, and RAM powered down.
Peripheral integration centers on event-driven operation: the Event Link Controller (ELCL) routes signals between peripherals (e.g., timer output → ADC trigger → interrupt), while the Data Transfer Controller (DTC) supports block, repeat, and chain transfers activated by interrupts - eliminating CPU overhead for memory-mapped peripheral data movement.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GLG2DFA#HA0 | Same 64-pin LFQFP package, identical peripherals, but 48 KB RAM instead of 48 KB - no functional difference; RAM capacity matches exactly. | No application difference; both rated for consumer (-40°C to +85°C) use with same flash (512 KB) and data flash (8 KB). | Select R7F100GLG2DFA#HA0 only if Renesas documentation explicitly lists it as functionally identical - verify part marking and revision history before substitution. |
| R7F100GLK2DFA#HA0 | Same package and temperature grade, but reduced 24 KB RAM and 256 KB code flash; lacks support for full CTSU2L mutual-capacitance mode (max 32 keys vs. 64). | Suitable for simpler HMI with fewer touch elements or smaller firmware footprint; not recommended for applications requiring >32-key touch matrix or large GUI buffers. | Choose R7F100GLK2DFA#HA0 only when firmware size and RAM usage are confirmed below 24 KB; verify CTSU2L configuration limits match design requirements. |
Compared with R7F100GLF2DFA#HA0, R7F100GLG2DFA#HA0 offers identical functionality and memory, while R7F100GLK2DFA#HA0 trades RAM and flash capacity for lower cost - making it viable only in resource-constrained implementations where CTSU2L key count and buffer depth are reduced.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GLF2DFA#HA0?
The R7F100GLF2DFA#HA0 supports up to 32 MHz operation using its high-speed on-chip oscillator, with guaranteed functionality across its full 1.6–5.5 V supply range. At 32 MHz, minimum instruction execution time is 0.03125 µs. The device maintains operation down to 1.6 V, enabling compatibility with single-cell Li-ion or multi-cell alkaline battery systems without external regulators.
Does the R7F100GLF2DFA#HA0 support hardware-based capacitive touch sensing, and what configurations are available?
Yes, the R7F100GLF2DFA#HA0 integrates the CTSU2L capacitive touch sensing unit supporting both self-capacitance (up to 32 independent keys) and mutual-capacitance (8×8 matrix, up to 64 keys). It includes hardware noise cancellation, auto-calibration, and programmable sensitivity - all configurable via registers without firmware math overhead. This enables robust touch interfaces in noisy environments like kitchen appliances.
What are the key low-power modes supported by the R7F100GLF2DFA#HA0, and how does SNOOZE mode differ from STOP mode?
The R7F100GLF2DFA#HA0 supports HALT, STOP, and SNOOZE modes. STOP mode powers down CPU, flash, and RAM but retains register and RAM content with 210 nA typical current. SNOOZE mode goes further: it disables CPU, flash, and RAM entirely while allowing autonomous execution of up to 32 pre-programmed steps (e.g., ADC sampling → comparison → interrupt) using dedicated sequencer hardware - achieving sub-µA average current in periodic sensing.
Can the R7F100GLF2DFA#HA0 perform background data flash writes while executing application code from program flash?
Yes, the R7F100GLF2DFA#HA0 supports Background Operation (BGO) for data flash. While application code runs from program flash, the data flash can be rewritten - enabling real-time logging, parameter updates, or calibration storage without interrupting system operation. Data flash endurance is rated at 1,000,000 write cycles (typ.), and BGO is managed via dedicated control registers and completion interrupts.
What communication interfaces are available on the R7F100GLF2DFA#HA0, and how many concurrent instances does it support?
The R7F100GLF2DFA#HA0 provides up to 6 UARTA channels (including LIN support), 10 I²C/Simplified I²C channels, and 8 simplified SPI (CSI) channels. These are implemented via the Serial Array Unit (SAU) and dedicated I²C modules - allowing concurrent use (e.g., UARTA0 for display, I²C0 for sensor, CSI0 for external flash) without resource conflict. All interfaces support hardware flow control, clock stretching, and interrupt-driven operation.
