Product details
Overview
R7F100GPK2DFA#BA0 from Renesas is a 100-pin, 256-KB code flash, 24-KB RAM RL78/G23 16-bit microcontroller operating from 1.6 to 5.5 V, featuring ultra-low power consumption (41 µA/MHz), 32-channel capacitive touch sensing, and integrated UART/I²C/SPI interfaces - deployed in battery-powered industrial HMI and sensor node applications.
For engineers reviewing the R7F100GPK2DFA#BA0 datasheet, R7F100GPK2DFA#BA0 pinout, R7F100GPK2DFA#BA0 application, or R7F100GPK2DFA#BA0 equivalent, this page delivers verified package mapping (LFQFP-100, 0.5-mm pitch), confirmed SNOOZE mode sequencer operation, real-time clock with alarm, 12-bit ADC (26 channels), and hardware DTC for autonomous data movement - all critical for low-power embedded firmware design and BOM validation.
Technical Context
The R7F100GPK2DFA#BA0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs at 32 MHz or 30.5 µs at 32.768 kHz). It integrates a dedicated SNOOZE mode sequencer (SMS) supporting 32 sequential low-power operations without CPU wake-up, and an Event Link Controller (ELCL) enabling hardware-triggered peripheral coordination.
Its memory subsystem includes 256 KB on-chip code flash (2-KB blocks), 8 KB data flash with background operation (BGO) and 1M-cycle endurance, and 24 KB RAM with 210-nA data retention. Power management features HALT, STOP, and SNOOZE modes, plus dual voltage detectors (LVD0/LVD1) and POR circuitry.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GPK2DFA#BA0?
The R7F100GPK2DFA#BA0 supports up to 32 MHz operation using its high-speed on-chip oscillator, with guaranteed functionality across the 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 timing, maintaining full functionality down to 1.6 V.
Does the R7F100GPK2DFA#BA0 support hardware-based capacitive touch sensing, and how many keys can it handle?
Yes, the R7F100GPK2DFA#BA0 integrates the CTSU2L capacitive sensing unit supporting both self-capacitance (up to 32 keys on single pins) and mutual-capacitance (up to 64 keys in 8×8 matrix) configurations. It operates within the 1.8–5.5 V VDD range and includes built-in noise cancellation - eliminating need for external touch controller ICs in R7F100GPK2DFA#BA0-based designs.
Can the R7F100GPK2DFA#BA0 perform flash memory writes while executing code from flash?
Yes, the R7F100GPK2DFA#BA0 supports Background Operation (BGO) for its 8 KB data flash memory, allowing CPU instructions to execute from code flash while concurrently rewriting data flash. This enables safe runtime parameter storage, firmware update staging, and logging without halting application execution - a core capability confirmed in the R7F100GPK2DFA#BA0 datasheet Section 1.1.
What debug and programming interfaces are available on the R7F100GPK2DFA#BA0?
The R7F100GPK2DFA#BA0 provides on-chip debugging via the TOOL0, TOOLRxD, and TOOLTxD pins - compatible with Renesas E2 emulator and standard SWD/JTAG adapters. It supports full read/write/erase functionality, breakpoint setting, and real-time variable monitoring. No external debug probe components are required, and the R7F100GPK2DFA#BA0 retains debug access even after flash security lock activation (with appropriate unlock sequence).
Is the R7F100GPK2DFA#BA0 qualified for industrial temperature operation?
No, the R7F100GPK2DFA#BA0 is specified for consumer applications with an operating ambient temperature range of -40°C to +85°C (denoted by "D" in the part number suffix). For industrial-grade operation up to +105°C, select the functionally identical R7F100GPK3CFA#AA0 variant, which carries the "C" field-of-application code and extended temperature qualification.
