It delivers ultra-low power consumption (41 µA/MHz active, 210 nA data retention), integrates capacitive touch sensing (CTSU2L), RTC, 16-bit TAU timers, UARTA/IICA/SAU interfaces, and supports industrial temperature range (−40 to +105°C) for embedded control in smart sensors and industrial HMI.
For engineers reviewing the R7F100GGF3CFB#HA0 datasheet, R7F100GGF3CFB#HA0 pinout, R7F100GGF3CFB#HA0 application, or R7F100GGF3CFB#HA0 equivalent, key selection criteria include its 48-pin LFQFP-0.5 mm pitch package, 128 KB flash/16 KB RAM configuration, C-grade industrial qualification, embossed tape packaging (#HA0), and verified support for SNOOZE mode sequencer, ELCL event linking, and CTSU2L self/mutual capacitance sensing up to 64 keys.
Technical Context
The R7F100GGF3CFB#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 power management includes HALT, STOP, and SNOOZE modes-where the SNOOZE mode sequencer executes up to 32 predefined commands (from 21 available) without CPU, flash, or RAM activation.
Peripheral integration includes a 21-function Logic and Event Link Controller (ELCL) enabling hardware-level signal routing between peripherals, a 12-bit A/D converter with 26-channel analog input and internal 1.48 V reference, dual 8-bit D/A outputs, two comparators with selectable internal/external reference, and a dedicated capacitive sensing unit (CTSU2L) supporting both self-capacitance (up to 32 keys) and mutual-capacitance (8×8 matrix, up to 64 keys) operation.

FAQ
What is the maximum operating frequency and corresponding instruction cycle time for the R7F100GGF3CFB#HA0?
The R7F100GGF3CFB#HA0 supports up to 32 MHz operation using the high-speed on-chip oscillator, achieving a minimum instruction execution time of 0.03125 µs. This timing is confirmed in the RL78/G23 datasheet (R01DS0395EJ0140, Section 1.1) and applies directly to the R7F100GGF3CFB#HA0 variant with its 128 KB flash configuration.
Does the R7F100GGF3CFB#HA0 support hardware-accelerated cryptographic functions?
No, the R7F100GGF3CFB#HA0 does not include dedicated cryptographic accelerators such as AES or SHA engines. Its security features are limited to flash block erase/write prohibition and boot swapping with flash shield window-intended for basic IP protection, not cryptographic processing. For secure boot or encryption, external co-processors or higher-tier RL78 devices (e.g., RL78/L13) are required.
Can the R7F100GGF3CFB#HA0's CTSU2L unit operate with VDD = 1.8 V?
Yes, the CTSU2L unit in the R7F100GGF3CFB#HA0 is specified to operate at VDD = 1.8–5.5 V per the RL78/G23 datasheet (Section 1.1, "Capacitive sensing unit"). This enables direct interfacing with 1.8 V logic domains and compatibility with low-voltage energy-harvesting power supplies without level-shifting.
What debug interface does the R7F100GGF3CFB#HA0 use, and is it compatible with standard tools?
The R7F100GGF3CFB#HA0 uses Renesas' on-chip debugging interface accessible via the TOOL0 and TOOLRxD/TOOLTxD pins (P40, P11, P12), supporting standard E2 studio and CS+ IDEs with Renesas E2 Lite or E2 emulator. No external JTAG adapter is needed-debugging operates over UART physical layer with SWD-like protocol, fully documented in the RL78/G23 User's Manual.
Is the R7F100GGF3CFB#HA0 pin-compatible with other RL78/G23 48-pin variants like R7F100GGL3CFB#HA0?
Yes, all RL78/G23 48-pin LFQFP variants-including R7F100GGF3CFB#HA0, R7F100GGL3CFB#HA0, and R7F100GGH3CFB#HA0-share identical pinout, electrical characteristics, and package dimensions (PLQP0048KB-B/PLQP0048KL-A). Memory and peripheral differences do not affect pin assignment or PCB layout.
