Renesas R7F100GPH2DFB#BA0

Overview

R7F100GPH2DFB#BA0 from Renesas is a 100-pin LFQFP, 5.0-V tolerant RL78/G23 16-bit MCU with 256 KB code flash, 8 KB data flash, and 24 KB RAM, operating from 1.6 to 5.5 V. It integrates capacitive touch sensing (CTSU2L), 12-bit ADC (26 channels), dual 8-bit DACs, RTC, and multiple serial interfaces including UARTA (up to 6 channels), IICA (up to 10 channels), and CSI (up to 8 channels), targeting low-power industrial HMI and sensor node applications.

For engineers reviewing the R7F100GPH2DFB#BA0 datasheet, R7F100GPH2DFB#BA0 pinout, R7F100GPH2DFB#BA0 application, or R7F100GPH2DFB#BA0 equivalent, key selection criteria include its 100-pin LFQFP-0.5 mm package, -40°C to +105°C industrial temperature grade, SNOOZE mode sequencer for ultra-low-power periodic sensing, and integrated CTSU2L supporting up to 64 keys in mutual capacitance mode.

Technical Context

The R7F100GPH2DFB#BA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). Its power management includes HALT, STOP, and SNOOZE modes - the latter enabling autonomous low-power sequencing of up to 32 operations without CPU wake-up.

Peripheral integration centers on event-driven operation via the Event Link Controller (ELCL), which routes signals between peripherals like timers, ADC, and communication units. The CTSU2L unit operates independently of CPU and flash/RAM, using self- or mutual-capacitance methods with programmable sensitivity and noise immunity settings.

FAQ

What is the maximum operating frequency and corresponding supply voltage range for the R7F100GPH2DFB#BA0?

The R7F100GPH2DFB#BA0 supports up to 32 MHz operation with its high-speed on-chip oscillator, and operates across the full 1.6–5.5 V supply range. At 32 MHz, minimum VDD is 2.7 V per the datasheet's AC characteristics table; below 2.7 V, maximum frequency scales down per the voltage-frequency curve - e.g., 16 MHz at 1.8 V. This ensures reliable timing across wide input voltage conditions.

Does the R7F100GPH2DFB#BA0 support hardware debugging, and what interface is used?

Yes, the R7F100GPH2DFB#BA0 supports on-chip debugging via the dedicated TOOL0 (pin 1) and TOOLRxD/TOOLTxD (pins 25/24) signals, compatible with Renesas E2 emulator and E2 Lite debuggers. Debugging uses a 4-wire SWD-like protocol over these pins - no JTAG header is required, reducing PCB footprint and enabling in-system programming and real-time trace without dedicated debug connectors.

How many capacitive touch channels does the R7F100GPH2DFB#BA0 support, and what configurations are available?

The R7F100GPH2DFB#BA0 integrates the CTSU2L unit supporting up to 32 self-capacitance keys (one pin per key) or up to 64 mutual-capacitance keys (8 × 8 matrix). Pin assignments are configurable via the CTSU2L registers, and all 100 pins except power, reset, and crystal inputs can be assigned as CTSU channels - providing full flexibility for custom touch layouts without external touch controllers.

What is the endurance and data retention specification for the data flash memory in the R7F100GPH2DFB#BA0?

The R7F100GPH2DFB#BA0 features 8 KB of data flash memory rated for 1,000,000 write/erase cycles (typical) and guaranteed data retention of 20 years at 85°C or 100 years at 25°C. Background operation (BGO) allows code execution from program flash while rewriting data flash - enabling seamless firmware parameter updates or sensor log writes without system interruption.

Can the R7F100GPH2DFB#BA0 operate from a 32.768 kHz crystal alone, and what functions remain active in that mode?

Yes, the R7F100GPH2DFB#BA0 can run entirely from the 32.768 kHz subsystem clock, enabling ultra-low-power operation. In this mode, the RTC, SNOOZE Mode Sequencer (SMS), key interrupt inputs, and CTSU2L remain fully functional - allowing periodic wake-up, touch scanning, and timekeeping while consuming only 210 nA in STOP mode with 4 KB RAM retention. The CPU and flash are disabled, but SMS can autonomously execute up to 32 commands before waking the core.
