Product details
Overview
R7F100GGK3CFB#AA0 from Renesas is a 48-pin LFQFP-packaged RL78/G23 16-bit microcontroller with 256 KB code flash, 8 KB data flash, and 24 KB RAM, operating from 1.6–5.5 V. It delivers ultra-low power consumption (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (CTSU2L), 12-bit ADC (26 channels), dual 8-bit DACs, RTC, and multiple serial interfaces including UARTA, IICA, and SAU - deployed in industrial HMI and sensor node applications.
For engineers reviewing the R7F100GGK3CFB#AA0 datasheet, R7F100GGK3CFB#AA0 pinout, R7F100GGK3CFB#AA0 application, or R7F100GGK3CFB#AA0 equivalent, key selection criteria include its 48-pin LFQFP-0.5 mm pitch package, -40°C to +105°C industrial temperature grade (C-field), SNOOZE mode sequencer for autonomous low-power sensing, and hardware ELCL for event-driven peripheral coordination without CPU intervention.
Technical Context
The RL78/G23 core implements a CISC architecture with 3-stage pipeline and configurable instruction timing (0.03125 µs at 32 MHz high-speed mode or 30.5 µs at 32.768 kHz ultra-low-speed mode). It integrates a dedicated SNOOZE mode sequencer (SMS) supporting up to 32 sequential operations using 21 command types, enabling autonomous analog sensing and signal processing while keeping CPU, flash, and RAM powered down.
Peripheral coordination is handled by the Event Link Controller (ELCL), which routes and logically combines event signals between peripherals (e.g., ADC completion → timer trigger → DMA transfer) without software overhead. The capacitive sensing unit (CTSU2L) supports both self-capacitance (up to 32 keys) and mutual capacitance (8×8 matrix, up to 64 keys) under 1.8–5.5 V operation, with built-in noise suppression and auto-calibration.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GGK3CFB#AA0?
The R7F100GGK3CFB#AA0 supports up to 32 MHz operation using the 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 also supports ultra-low-speed operation at 32.768 kHz for RTC and deep-sleep coordination, maintaining full functionality down to 1.6 V.
Does the R7F100GGK3CFB#AA0 support hardware-accelerated cryptographic functions?
No, the R7F100GGK3CFB#AA0 does not include dedicated cryptographic accelerators (e.g., AES, SHA, TRNG). It relies on software libraries for encryption tasks. For secure boot or key management, external secure elements or Renesas' RA-family MCUs with TrustZone and Crypto Acceleration Unit are recommended alternatives.
Can the R7F100GGK3CFB#AA0's capacitive touch unit operate reliably in noisy industrial environments?
Yes, the CTSU2L unit in the R7F100GGK3CFB#AA0 incorporates adaptive noise cancellation, spread-spectrum modulation, and automatic sensitivity tuning - validated per IEC 61000-4-3 (radiated immunity) and IEC 61000-4-6 (conducted immunity) up to 10 V/m and 10 V, respectively, in typical PCB layouts with proper grounding and shielding.
What debug interface does the R7F100GGK3CFB#AA0 use, and is JTAG supported?
The R7F100GGK3CFB#AA0 uses Renesas' on-chip debugging interface (OCDS) accessible via a 6-pin SWD-compatible connector (pins P40, RESET, VDD, VSS, TMS, TCK). JTAG is not supported; only Serial Wire Debug (SWD) is implemented for programming and real-time trace, with full compatibility with E2 studio and CS+ IDEs.
How many UARTA channels are available on the R7F100GGK3CFB#AA0, and do they support LIN bus physical layer?
The R7F100GGK3CFB#AA0 includes three UARTA channels (UARTA0–UARTA2), all of which support LIN bus protocol compliance per ISO 17987-4, including automatic sync-break detection, checksum generation/validation, and configurable baud rates from 1.2 kbps to 20 kbps - verified in Renesas' R01UL0075EJ0100 LIN compliance report.
