Product details
Overview
R7F100GFG2DFP#AA0 from Renesas is a 44-pin LQFP-packaged RL78/G23 16-bit microcontroller with 192 KB code flash, 8 KB data flash, and 20 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, and real-time clock - deployed in battery-powered industrial HMI and sensor edge nodes.
For engineers reviewing the R7F100GFG2DFP#AA0 datasheet, R7F100GFG2DFP#AA0 pinout, R7F100GFG2DFP#AA0 application, or R7F100GFG2DFP#AA0 equivalent, key selection criteria include its 44-pin LQFP-0.8 mm pitch package, -40°C to +85°C consumer-grade temperature range, and support for SNOOZE mode sequencer-driven autonomous peripheral operation without CPU wake-up.
Technical Context
The R7F100GFG2DFP#AA0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting configurable instruction execution times 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 low-power processes using 21 command types, enabling sensor polling and threshold comparison without RAM/CPU activation.
Peripheral integration includes Logic and Event Link Controller (ELCL) for hardware-triggered signal routing between modules, Data Transfer Controller (DTC) with chain transfer, and dual serial interface types: up to 10 I²C/Simplified I²C channels and 6 UART/UARTA (LIN-capable) channels - all configurable via peripheral I/O redirection register (PIOR).

FAQ
What is the maximum operating frequency and corresponding current consumption of the R7F100GFG2DFP#AA0?
The R7F100GFG2DFP#AA0 operates up to 32 MHz using its high-speed on-chip oscillator (±1.0% accuracy). At this frequency, it draws 41 µA per MHz - resulting in approximately 1.31 mA total active current. This value is measured under typical conditions (VDD = 3.3 V, TA = 25°C) and excludes peripheral-specific current contributions such as ADC conversion or CTSU2L charging.
Does the R7F100GFG2DFP#AA0 support hardware-accelerated cryptographic functions?
No, the R7F100GFG2DFP#AA0 does not include dedicated cryptographic accelerators or TRNG. It relies on software libraries for AES or SHA operations. Security features are limited to flash memory block erase/write prohibition and boot swapping with flash shield window - intended for IP protection rather than runtime encryption.
Can the R7F100GFG2DFP#AA0's capacitive touch unit operate reliably in wet or noisy environments?
Yes, the CTSU2L unit in the R7F100GFG2DFP#AA0 supports noise cancellation techniques including spread spectrum modulation and mutual-capacitance scanning, which improves immunity to water overlay and EMI. Renesas provides dedicated firmware libraries (CTSU2L Driver) with adaptive threshold tuning - validated for operation with up to 2 mm water film and 10 Vpp conducted noise.
What debug interfaces are supported by the R7F100GFG2DFP#AA0, and what pins do they use?
The R7F100GFG2DFP#AA0 supports on-chip debugging via the FINE interface using pins P40 (TOOL0) and RESET. It does not implement SWD or JTAG. Debugging requires Renesas E2 or E2 Lite emulator and CS+ or e2 studio IDE. No additional pins are consumed beyond TOOL0 and RESET - no dedicated debug port multiplexing is needed.
Is the R7F100GFG2DFP#AA0 pin-compatible with other RL78/G23 variants in the same 44-pin LQFP package?
Yes, all RL78/G23 devices in the 44-pin LQFP-0.8 mm pitch package (e.g., R7F100GFJ2DFP#AA0, R7F100GFK2DFP#AA0) share identical pinouts and electrical characteristics. Memory size, temperature grade, and flash configuration differ, but PCB layout, decoupling, and peripheral routing remain fully interchangeable.
