Product details
Overview
R7F100GLH2DFA#BA0 from Renesas is a 64-pin, consumer-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), integrates capacitive touch sensing (CTSU2L), RTC, 16-bit timers, 12-bit ADC (26 channels), and dual DAC outputs - deployed in battery-powered home appliances and industrial HMI panels.
For engineers reviewing the R7F100GLH2DFA#BA0 datasheet, R7F100GLH2DFA#BA0 pinout, R7F100GLH2DFA#BA0 application, or R7F100GLH2DFA#BA0 equivalent, key selection criteria include its LQFP-64 (0.65 mm pitch) package, -40 to +85°C temperature grade, integrated SNOOZE mode sequencer for autonomous low-power sensing, and hardware ELCL for event-driven peripheral coordination without CPU intervention.
Technical Context
The R7F100GLH2DFA#BA0 implements the RL78 CPU core with a 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 memory subsystem includes 128 KB code flash (2 KB block size), 8 KB background-operable data flash (1M rewrite cycles), and 16 KB SRAM with 4 KB retained at 210 nA.
Peripheral architecture features a configurable SNOOZE mode sequencer (SMS) executing up to 32 commands across 21 instruction types without CPU wake-up, plus an Event Link Controller (ELCL) enabling direct hardware-level signal routing between peripherals - eliminating software overhead for real-time sensor-to-actuator workflows.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GLH2DFA#BA0?
The R7F100GLH2DFA#BA0 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 functions.
Does the R7F100GLH2DFA#BA0 support hardware-based capacitive touch sensing, and what configurations are available?
Yes, the R7F100GLH2DFA#BA0 integrates the CTSU2L capacitive touch sensing unit supporting both self-capacitance (up to 32 keys, one pin per key) and mutual capacitance (up to 64 keys in 8×8 matrix). It operates from 1.8–5.5 V and includes built-in noise cancellation for reliable operation in electrically noisy environments like kitchen appliances.
How does the SNOOZE mode sequencer (SMS) in the R7F100GLH2DFA#BA0 reduce system power versus conventional interrupt-driven polling?
The SMS in the R7F100GLH2DFA#BA0 executes preloaded command sequences - such as ADC conversion, comparison, and GPIO toggle - entirely in hardware without CPU, flash, or RAM activation. This reduces average current to sub-microamp levels during periodic sensing tasks, whereas interrupt-driven polling forces full wake-up, increasing power by 10–100× per event.
What communication interfaces are available on the R7F100GLH2DFA#BA0, and which support LIN bus physical layer compliance?
The R7F100GLH2DFA#BA0 provides up to 6 UART channels, with UARTA explicitly supporting LIN bus protocol (including break detection, sync field handling, and checksum calculation). It also includes up to 10 I²C channels and 8 CSI (SPI-compatible) channels - all configurable via peripheral I/O redirection registers for flexible PCB routing.
Is the R7F100GLH2DFA#BA0 pin-compatible with other RL78/G23 variants in the same 64-pin LQFP package?
Yes, all RL78/G23 devices in the 64-pin LQFP-0.65mm package - including R7F100GLF2DFA#BA0 through R7F100GLN2DFA#BA0 - share identical pinouts, electrical characteristics, and peripheral mapping. Memory and feature differences (e.g., flash size, RAM, CTSU presence) do not affect pin function assignment or PCB layout.
