Renesas R7F100GGF2DNP#AA0

Overview

R7F100GGF2DNP#AA0 from Renesas is a 48-pin HWQFN-packaged RL78/G23 16-bit microcontroller with 128 KB code flash, 8 KB data flash, and 16 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), 16-bit TAU timers, RTC, and multiple serial interfaces including UARTA, IICA, and SAU for embedded control in battery-powered consumer devices.

For engineers reviewing the R7F100GGF2DNP#AA0 datasheet, R7F100GGF2DNP#AA0 pinout, R7F100GGF2DNP#AA0 application, or R7F100GGF2DNP#AA0 equivalent, key selection criteria include its 48-pin HWQFN-0.5 mm pitch package, -40 to +85°C consumer-grade temperature range, 128 KB flash/16 KB RAM memory configuration, CTSU2L capacitive sensing support, and SNOOZE mode sequencer for autonomous low-power sensor polling.

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 on-chip oscillator) or 30.5 µs at 32.768 kHz (subsystem clock). It integrates a SNOOZE mode sequencer (SMS) supporting up to 32 sequential operations using 21 command types, enabling CPU-free periodic sensing without RAM/flash activation.

Peripheral integration includes a Logic and Event Link Controller (ELCL) for configurable signal routing between peripherals, a Data Transfer Controller (DTC) with chain transfer capability, and a capacitive sensing unit (CTSU2L) supporting both self-capacitance (up to 32 keys) and mutual capacitance (8×8 matrix, up to 64 keys) under 1.8–5.5 V operation.

FAQ

What is the maximum operating frequency and corresponding supply voltage range for R7F100GGF2DNP#AA0?

R7F100GGF2DNP#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 VDD range. The ±1.0% oscillator accuracy is specified for VDD = 1.8–5.5 V and TA = -20 to +85°C-no external crystal is required for timing-critical applications within this envelope.

Does R7F100GGF2DNP#AA0 support capacitive touch sensing, and what configurations are available?

Yes, R7F100GGF2DNP#AA0 integrates the CTSU2L capacitive sensing unit supporting both self-capacitance (up to 32 independent keys using single-pin electrodes) and mutual capacitance (up to 64 keys in an 8×8 matrix). It operates over the full 1.8–5.5 V VDD range and requires no external components-electrodes connect directly to TSxx pins (e.g., TS00–TS05, TSCAP).

What low-power modes are available on R7F100GGF2DNP#AA0, and what is the lowest achievable current draw?

R7F100GGF2DNP#AA0 offers HALT, STOP, and SNOOZE modes. In STOP mode with 4 KB of RAM retained, it achieves 210 nA typical current draw. Active-mode current is 41 µA/MHz at 32 MHz. The SNOOZE mode sequencer enables autonomous peripheral operation-including CTSU scans and ADC conversions-without CPU, flash, or RAM activation, further reducing system-level power.

Can R7F100GGF2DNP#AA0 perform background data flash writes while executing code from main flash memory?

Yes, R7F100GGF2DNP#AA0 supports Background Operation (BGO) for its 8 KB data flash memory. This allows the CPU to execute instructions from code flash while simultaneously erasing or programming data flash sectors-enabling real-time logging, parameter updates, or firmware patching without halting application execution.

What serial communication interfaces are integrated into R7F100GGF2DNP#AA0, and how many instances does each support?

R7F100GGF2DNP#AA0 integrates UARTA (3 channels), IICA (4 channels), and SAU (3 to 6 channels supporting SPI, UART, and I²C). Specifically, it provides three UARTA modules (supporting LIN-bus), four IICA masters/slaves, and six SAU channels configurable as CSI (SPI), UART, or simplified I²C-enabling concurrent communication with displays, sensors, and wireless modules.
