Product details
Overview
R7F100GLH3CFA#HA0 from Renesas is a 64-pin, industrial-grade 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), RTC, 16-bit timers, UART/I²C/SPI interfaces, and hardware-based SNOOZE mode sequencer for autonomous low-power operation in battery-powered HMI and sensor nodes.
For engineers reviewing the R7F100GLH3CFA#HA0 datasheet, R7F100GLH3CFA#HA0 pinout, R7F100GLH3CFA#HA0 application, or R7F100GLH3CFA#HA0 equivalent, key selection criteria include its 64-pin LQFP-0.65mm package, -40°C to +105°C industrial temperature rating, CTSU2L support for up to 64 keys, and SNOOZE mode sequencer enabling CPU-free periodic sensing - critical for energy-constrained industrial control panels and smart sensors.
Technical Context
The R7F100GLH3CFA#HA0 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode). Its SNOOZE mode sequencer (SMS) executes up to 32 preconfigured commands-including ADC sampling, comparator evaluation, and CTSU2L scanning-without CPU, flash, or RAM 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 dual-voltage I/O (1.8/2.5/3.0 V compatible) on select pins. The device uses a dedicated REGC capacitor for internal regulator stability and supports background data flash rewriting (BGO) with 1M write cycles.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GLH3CFA#HA0?
The R7F100GLH3CFA#HA0 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 deep-sleep timing, maintaining full functionality down to 1.6 V.
Does the R7F100GLH3CFA#HA0 support hardware debugging, and what interface is used?
Yes, the R7F100GLH3CFA#HA0 supports on-chip debugging via the dedicated TOOL0 (pin 5) and TOOLRxD/TOOLTxD (pins 25/24) signals, compatible with Renesas E2 emulator and E2 Lite. Debugging operates independently of the main application code and does not require dedicated SWD/JTAG pins-reducing pin count overhead while enabling full breakpoint, watchpoint, and memory inspection capabilities.
How many capacitive touch channels does the CTSU2L unit support on the R7F100GLH3CFA#HA0, and what configurations are possible?
The CTSU2L unit on the R7F100GLH3CFA#HA0 supports up to 32 self-capacitance keys (one per pin) or 64 mutual-capacitance keys (8×8 matrix) using dedicated CCD00–CCD06 pins plus shared I²C lines. It operates under VDD = 1.8–5.5 V and includes automatic noise cancellation, drift compensation, and programmable scan speed-enabling reliable touch detection even in electrically noisy industrial environments.
What are the key power management features that distinguish the R7F100GLH3CFA#HA0 from earlier RL78 generations?
The R7F100GLH3CFA#HA0 introduces the SNOOZE mode sequencer (SMS), which executes up to 32 predefined operations-including ADC sampling, CTSU2L scanning, and comparator evaluation-without CPU, flash, or RAM activation. Combined with 41 µA/MHz active current and 210 nA data retention, this enables true autonomous low-power operation unattainable in prior RL78 devices, reducing system-level power by >90% in periodic sensing applications.
Can the R7F100GLH3CFA#HA0 perform background data flash writes while executing application code, and what is the endurance rating?
Yes, the R7F100GLH3CFA#HA0 supports Background Operation (BGO) for data flash, allowing instruction execution from code flash while simultaneously rewriting data flash sectors. The data flash is rated for 1,000,000 erase/write cycles (typical), with hardware flash shield window and block erase prohibition features to prevent accidental corruption-critical for secure firmware updates and field-parameter storage in industrial deployments.
