Product details
Overview
R7F100GLH3CFB#BA0 from Renesas is a 64-pin LFQFP, industrial-grade RL78/G23 16-bit MCU with 192 KB code flash, 8 KB data flash, and 24 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 (up to 64 keys), and dual 16-bit timer arrays for motor control and sensor interface in battery-powered industrial HMI systems.
For engineers reviewing the R7F100GLH3CFB#BA0 datasheet, R7F100GLH3CFB#BA0 pinout, R7F100GLH3CFB#BA0 application, or R7F100GLH3CFB#BA0 equivalent, key selection criteria include its 64-pin LFQFP-0.5 mm pitch package, -40°C to +105°C temperature rating, SNOOZE mode sequencer for autonomous low-power sensing, and hardware ELCL for event-driven peripheral coordination without CPU wake-up.
Technical Context
The R7F100GLH3CFB#BA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, 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 executes up to 32 preconfigured commands-including ADC sampling, comparison, and conditional branching-without CPU, RAM, or flash activation.
Peripheral integration includes a 10-bit A/D converter with 26 input channels, two 8-bit D/A outputs, two comparators with selectable internal/external reference, and a logic/event link controller (ELCL) enabling direct signal routing between UART, timers, and CTSU without software intervention.

FAQ
What is the maximum operating frequency and corresponding current consumption of the R7F100GLH3CFB#BA0?
The R7F100GLH3CFB#BA0 operates at up to 32 MHz using the high-speed on-chip oscillator. At this frequency and VDD = 3.3 V, typical active current is 41 µA/MHz-resulting in ~1.3 mA total. This value is measured under specified conditions in the R01DS0395EJ0140 datasheet, Section 23.3.
Does the R7F100GLH3CFB#BA0 support hardware-based capacitive touch sensing without CPU involvement?
Yes, the R7F100GLH3CFB#BA0 integrates the CTSU2L unit with autonomous scan engine and the SNOOZE mode sequencer (SMS). SMS can execute up to 32 CTSU-related commands-including electrode charging, ADC conversion, and threshold comparison-entirely without CPU, RAM, or flash activation, reducing average current to sub-µA levels during touch polling.
What are the supported package and pin-count options for the R7F100GLH3CFB#BA0?
The R7F100GLH3CFB#BA0 is exclusively offered in 64-pin LFQFP (10 × 10 mm, 0.50-mm pitch) with package code FB. Per Renesas ordering nomenclature, the "L" in the part number denotes 512 KB flash-but this specific variant uses "H" for 192 KB, confirming it is the 64-pin, 192 KB configuration. No other package or pin count is assigned to this exact orderable part number.
Can the R7F100GLH3CFB#BA0 operate from a single 1.8 V supply, and what peripherals remain functional?
Yes, the R7F100GLH3CFB#BA0 supports VDD = 1.6–5.5 V. At 1.8 V, the high-speed on-chip oscillator (up to 16 MHz), CTSU2L (self-capacitance mode only), 10-bit ADC (with internal 1.48 V reference), and most digital peripherals remain fully operational. The 32.768 kHz RTC oscillator and certain analog features (e.g., D/A output range) are limited or disabled below 2.7 V per Section 23.1 of the datasheet.
How does the Event Link Controller (ELCL) in the R7F100GLH3CFB#BA0 improve system responsiveness?
The ELCL in the R7F100GLH3CFB#BA0 enables direct hardware routing of event signals-such as UART receive completion, timer overflow, or CTSU scan end-to target peripherals like timers or ADC triggers. This eliminates software interrupt latency and CPU polling, allowing sub-microsecond response times for time-critical actions like motor fault shutdown or synchronized sensor sampling.
