Product details
Overview
R7F100GLG2DFA#HA0 from Renesas is a 64-pin LFQFP-packaged RL78/G23 16-bit microcontroller 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 (CTSU2L), and dual-clock domain support for ultra-low-power SNOOZE mode execution-targeting battery-powered industrial HMI and sensor node applications.
For engineers reviewing the R7F100GLG2DFA#HA0 datasheet, R7F100GLG2DFA#HA0 pinout, R7F100GLG2DFA#HA0 application, or R7F100GLG2DFA#HA0 equivalent, key selection criteria include its 64-pin LFQFP-0.5 mm pitch package, -40°C to +85°C consumer-grade temperature range, and verified support for simultaneous UARTA (up to 6 channels), IICA (up to 10 channels), and SAU-based SPI/I²C/UART peripherals without external clock sources.
Technical Context
The R7F100GLG2DFA#HA0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling configurable instruction timing from 0.03125 µs (32 MHz high-speed oscillator) to 30.5 µs (32.768 kHz subsystem clock). Its SNOOZE mode sequencer (SMS) executes up to 32 preconfigured operations-including ADC sampling, comparator evaluation, and CTSU2L scanning-without CPU, RAM, or flash activation.
Peripheral integration includes a 12-bit A/D converter (26-channel input), dual 8-bit D/A outputs (0–VDD range), two comparators with selectable internal/external reference, and an ELCL that routes event signals between timers, ADC, CTSU2L, and communication interfaces-enabling autonomous low-power state transitions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GLG3CFA#AA0 | Same 512 KB/48 KB/8 KB memory, but industrial-grade (-40°C to +105°C) and tray-packaged; lacks consumer-grade #HA0 tape packaging | Targeted for factory automation where extended temperature range is mandatory; not qualified for consumer appliance certifications | Select when ambient operating temperature exceeds +85°C or JEDEC J-STD-020 moisture sensitivity level (MSL) compliance is required |
| R7F100GLL2DFA#HA0 | 384 KB code flash, 32 KB RAM, same 64-pin LFQFP-0.5 mm package and -40°C to +85°C rating; identical peripheral set and pinout | Cost-optimized variant for applications with smaller firmware footprint and lower RAM demand (e.g., simple sensor polling without complex UI) | Select when application firmware size remains under 350 KB and real-time multitasking requires ≤32 KB RAM-reducing BoM cost without redesign |
Compared with R7F100GLG2DFA#HA0, the R7F100GLG3CFA#AA0 offers guaranteed operation at +105°C but requires requalification for consumer safety standards, while the R7F100GLL2DFA#HA0 provides identical packaging and temperature range with 128 KB less flash and 16 KB less RAM-enabling direct PCB reuse for scaled-down feature sets.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GLG2DFA#HA0?
The R7F100GLG2DFA#HA0 supports a maximum operating frequency of 32 MHz using the high-speed on-chip oscillator, with guaranteed operation across the full 1.6–5.5 V supply range. At 32 MHz, the minimum instruction execution time is 0.03125 µs. The device also supports ultra-low-speed operation at 32.768 kHz with 30.5 µs instruction timing for RTC and deep-sleep functions-both modes validated over the entire -40°C to +85°C ambient temperature range specified for the R7F100GLG2DFA#HA0.
Does the R7F100GLG2DFA#HA0 support hardware-based capacitive touch sensing, and what configurations are available?
Yes, the R7F100GLG2DFA#HA0 integrates the CTSU2L (Capacitive Touch Sensing Unit Level 2) supporting both self-capacitance (up to 32 independent keys) and mutual-capacitance (8×8 matrix, up to 64 keys) configurations. It includes built-in noise cancellation, auto-calibration, and low-power scanning modes-enabling reliable touch detection even in electrically noisy industrial environments. All CTSU2L functionality is implemented in dedicated hardware and operates independently of the CPU, allowing touch scanning during SNOOZE mode.
Can the R7F100GLG2DFA#HA0 execute code while rewriting data flash memory?
Yes, the R7F100GLG2DFA#HA0 supports Background Operation (BGO) for data flash memory. This allows the CPU to execute instructions from code flash memory while simultaneously erasing or programming data flash sectors. BGO is fully supported in all operating modes except HALT and STOP, and is essential for applications requiring real-time parameter updates-such as field calibration or firmware configuration-without interrupting system operation or introducing latency.
What are the key low-power modes supported by the R7F100GLG2DFA#HA0, and what is the typical current consumption in each?
The R7F100GLG2DFA#HA0 supports HALT (41 µA/MHz active), STOP (210 nA with 4 KB RAM retention), and SNOOZE modes. In SNOOZE mode, only the SMS, CTSU2L, and selected peripherals remain active-drawing ~1.2 µA typical while performing autonomous ADC scans or touch polling. All modes retain full register and RAM state, and wake-up from STOP is achieved in <3.5 µs via external interrupt or RTC alarm-verified across the -40°C to +85°C range for the R7F100GLG2DFA#HA0.
Is the R7F100GLG2DFA#HA0 pin-compatible with other RL78/G23 variants in the same 64-pin LFQFP package?
Yes, all RL78/G23 devices in the 64-pin LFQFP-0.5 mm package-including R7F100GLG2DFA#HA0, R7F100GLL2DFA#HA0, and R7F100GLK2DFA#HA0-share identical pinouts, electrical characteristics, and peripheral mapping. Memory size differences (512 KB vs. 384 KB vs. 256 KB flash) and RAM capacity do not affect pin function assignment or I/O behavior, enabling drop-in replacement for firmware updates or cost optimization without PCB revision.
