Renesas R7F100GPH3CFB#AA0

Overview

R7F100GPH3CFB#AA0 from Renesas is a 100-pin LFQFP, industrial-grade RL78/G23 16-bit MCU with 192 KB code flash, 8 KB data flash, and 20 KB RAM, operating from 1.6–5.5 V at -40 to +105°C. It delivers true low-power operation (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (up to 64 keys), and dual ADC resolution (8/10/12-bit) for embedded control in battery-powered industrial HMI and sensor nodes.

For engineers reviewing the R7F100GPH3CFB#AA0 datasheet, R7F100GPH3CFB#AA0 pinout, R7F100GPH3CFB#AA0 application, or R7F100GPH3CFB#AA0 equivalent, key selection criteria include its 100-pin LFQFP-0.5 mm package, SNOOZE mode sequencer for autonomous low-power sensing, and hardware event link controller (ELCL) enabling interrupt-free peripheral coordination in real-time control loops.

Technical Context

The RL78/G23 core implements a CISC architecture with 3-stage pipeline and configurable instruction timing - supporting ultra-low-speed execution (30.5 µs @ 32.768 kHz) for RTC and HALT modes, and high-speed operation (0.03125 µs @ 32 MHz) for compute-intensive tasks. Its memory subsystem includes 192 KB code flash (2 KB block size), 8 KB background-operable data flash (1M rewrite cycles), and 20 KB SRAM with 4 KB retained in STOP mode.

Peripheral integration centers on autonomous operation: the SNOOZE mode sequencer executes up to 32 preconfigured commands (e.g., ADC sampling, comparison, GPIO toggle) without CPU wake-up; the ELCL routes 21 event signals between peripherals (e.g., timer overflow → ADC trigger → DMA transfer); and the CTSU2L unit supports self- and mutual-capacitance sensing with hardware waveform matching for remote control decoding.

FAQ

What is the maximum operating frequency and corresponding supply voltage range for R7F100GPH3CFB#AA0?

R7F100GPH3CFB#AA0 operates up to 32 MHz 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 STOP mode - maintaining timing accuracy without external crystal.

Does R7F100GPH3CFB#AA0 support hardware-based capacitive touch sensing, and what configurations are available?

Yes, R7F100GPH3CFB#AA0 integrates the CTSU2L capacitive touch sensing unit supporting both self-capacitance (up to 32 keys on single pins) and mutual-capacitance (8×8 matrix = 64 keys). It operates across the full VDD range of 1.8–5.5 V and includes hardware noise cancellation - enabling reliable touch performance in electrically noisy industrial settings without CPU intervention.

How does the SNOOZE mode sequencer in R7F100GPH3CFB#AA0 reduce system power consumption?

The SNOOZE mode sequencer in R7F100GPH3CFB#AA0 executes up to 32 preloaded commands - such as ADC sampling, value comparison, and GPIO toggling - entirely autonomously without CPU involvement. This eliminates wake-up latency and CPU power draw during periodic sensing tasks, achieving sub-100 µA average current in applications like battery-powered environmental monitors.

Can R7F100GPH3CFB#AA0 perform background data flash writes while executing application code from program flash?

Yes, R7F100GPH3CFB#AA0 supports Background Operation (BGO) for its 8 KB data flash memory. Instructions can be fetched and executed from code flash while data flash is being rewritten - enabling seamless firmware updates, parameter logging, or configuration storage without interrupting real-time application tasks.

What peripheral event linking capability does R7F100GPH3CFB#AA0 provide, and how is it implemented?

R7F100GPH3CFB#AA0 features the Event Link Controller (ELCL), a hardware peripheral that routes 21 different event signals (e.g., timer match, ADC end-of-conversion, UART transmit complete) between other peripherals without CPU or interrupt involvement. This enables deterministic, low-latency chains - such as "timer overflow → trigger ADC → transfer result via DTC" - improving real-time responsiveness and reducing software overhead.
