Product details
Overview
R7F100GPL3CFA#HA0 from Renesas is a 100-pin industrial-grade 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 integrates capacitive touch sensing (up to 64 keys), 12-bit ADC (26 channels), dual 8-bit DACs, RTC, and ultra-low-power STOP mode (210 nA data retention). Used in battery-powered industrial HMI and sensor nodes.
For engineers reviewing the R7F100GPL3CFA#HA0 datasheet, R7F100GPL3CFA#HA0 pinout, R7F100GPL3CFA#HA0 application, or R7F100GPL3CFA#HA0 equivalent, key selection criteria include its 100-pin LFQFP-0.5 mm package, -40°C to +105°C temperature rating, SNOOZE mode sequencer for autonomous low-power sensing, and integrated CTSU2L capacitive touch controller supporting mutual capacitance matrix operation.
Technical Context
The R7F100GPL3CFA#HA0 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). It features a dedicated SNOOZE mode sequencer (SMS) that executes up to 32 preconfigured commands-including comparisons and calculations-without CPU, RAM, or flash activation, enabling deterministic low-power periodic sensing.
Peripheral integration includes Logic and Event Link Controller (ELCL) for hardware-triggered signal routing between peripherals, Data Transfer Controller (DTC) with chain transfer support, and dual-mode CTSU2L supporting both self-capacitance (32 keys) and mutual capacitance (8×8 matrix, 64 keys) with built-in noise suppression and auto-tuning.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GSL3CFA#HA0 | Same 100-pin LFQFP package and industrial temp grade, but 768 KB code flash, 48 KB RAM, and identical peripheral set. | Targeted at applications requiring larger firmware footprint (e.g., embedded web server, advanced encryption stack). | Select when >512 KB flash is needed; pinout and software compatibility are maintained across RL78/G23 family. |
| R7F100GPL3CFA#AA0 | Identical electrical specs and functionality, but supplied in tray packaging instead of embossed tape (#HA0 → #AA0). | No functional difference; choice depends solely on production line feeding requirements (tape-and-reel vs. tray). | Choose #AA0 for manual or low-volume prototyping; #HA0 is optimized for automated SMT placement. |

FAQ
What is the maximum operating frequency and corresponding instruction cycle time for the R7F100GPL3CFA#HA0?
The R7F100GPL3CFA#HA0 supports a maximum operating frequency of 32 MHz using the high-speed on-chip oscillator. At this speed, the minimum instruction execution time is 0.03125 µs. This timing is achievable with the high-speed on-chip oscillator enabled and configured for 32-MHz operation, as specified in the RL78/G23 datasheet Rev.1.40.
Does the R7F100GPL3CFA#HA0 support hardware-based capacitive touch sensing, and what configurations are available?
Yes, the R7F100GPL3CFA#HA0 integrates the CTSU2L capacitive sensing unit. It supports both self-capacitance (up to 32 keys on single pins) and mutual capacitance (up to 64 keys in an 8×8 matrix configuration). The unit includes hardware auto-tuning, noise cancellation, and dedicated electrode pins (e.g., P30–P31, P60–P62, P70–P73) mapped in the 100-pin LFQFP package.
What packaging and temperature grade does the R7F100GPL3CFA#HA0 use, and how is it indicated in the part number?
The R7F100GPL3CFA#HA0 uses a 100-pin LFQFP package with 0.50-mm pitch and is rated for industrial temperature operation (-40°C to +105°C). This is encoded in the part number: "P" denotes 100-pin count, "L" indicates 512 KB flash, "3" specifies industrial ambient range (3C), "C" denotes industrial field-of-application, "FA" identifies LFQFP-0.5 mm, and "#HA0" specifies embossed tape packaging.
How does the SNOOZE mode sequencer (SMS) in the R7F100GPL3CFA#HA0 reduce system power consumption?
The SNOOZE mode sequencer in the R7F100GPL3CFA#HA0 executes up to 32 preloaded commands-including value comparisons and arithmetic operations-without waking the CPU, flash, or RAM. This enables autonomous periodic tasks like sensor polling or threshold checking at sub-microamp average current, significantly extending battery life in intermittently active applications.
Can the R7F100GPL3CFA#HA0 perform background data flash writes while executing code from main flash memory?
Yes, the R7F100GPL3CFA#HA0 supports Background Operation (BGO) for its 8 KB data flash memory. This allows the CPU to execute instructions from code flash while simultaneously erasing or programming data flash sectors-a critical capability for reliable firmware updates and secure data logging without system interruption.
