Product details
Overview
R7F100GLH2DFB#AA0 from Renesas is a 64-pin LFQFP, 128-KB code flash, 16-KB RAM RL78/G23 16-bit microcontroller operating from 1.6 to 5.5 V, featuring ultra-low-power operation (41 µA/MHz), 210-nA data retention, integrated capacitive touch sensing (CTSU2L), and dual UART/I²C/SPI interfaces. It targets battery-powered industrial control panels requiring long-life operation and human interface integration.
For engineers reviewing the R7F100GLH2DFB#AA0 datasheet, R7F100GLH2DFB#AA0 pinout, R7F100GLH2DFB#AA0 application, or R7F100GLH2DFB#AA0 equivalent, key selection criteria include its 64-pin LFQFP-0.5mm package, -40°C to +85°C industrial temperature grade, 128-KB flash/16-KB RAM memory configuration, and support for SNOOZE mode sequencer and ELCL event linking without CPU intervention.
Technical Context
The R7F100GLH2DFB#AA0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). It integrates a SNOOZE mode sequencer (SMS) capable of executing 32 sequential low-power processes using 21 command types, enabling autonomous sensor polling and wake-up decision logic.
Its peripheral set includes a Logic and Event Link Controller (ELCL) for hardware-level signal routing between peripherals, a 10-bit A/D converter with up to 26 input channels and internal temperature sensor, and a capacitive sensing unit (CTSU2L) supporting both self-capacitance (up to 32 keys) and mutual capacitance (8×8 matrix, up to 64 keys) configurations.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GLH2DFB#AA0?
The R7F100GLH2DFB#AA0 supports a maximum operating frequency of 32 MHz using the high-speed on-chip oscillator, with guaranteed operation across its full 1.6 V to 5.5 V supply range. At 32 MHz, the 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, maintaining full functionality down to 1.6 V.
Does the R7F100GLH2DFB#AA0 support hardware-accelerated cryptographic functions?
No, the R7F100GLH2DFB#AA0 does not include dedicated hardware cryptographic accelerators such as AES or SHA engines. Its security features are limited to flash memory block erase/write prohibition and boot swapping with flash shield window. For applications requiring cryptographic processing, software libraries must be implemented in the 128 KB code flash, leveraging the RL78's multiply/divide instructions for optimized performance.
How many capacitive touch channels can the R7F100GLH2DFB#AA0 support in mutual capacitance mode?
The R7F100GLH2DFB#AA0 supports up to 64 capacitive touch keys in mutual capacitance mode using an 8 × 8 electrode matrix configuration. This capability is provided by the integrated CTSU2L unit, which operates independently of the CPU and supports automatic scan, noise cancellation, and baseline tracking-all configurable via registers without firmware intervention.
What debug interface options are available for the R7F100GLH2DFB#AA0 during development?
The R7F100GLH2DFB#AA0 supports on-chip debugging via the single-wire SWD (Serial Wire Debug) interface using the TOOL0 and TOOLRxD/TOOLTxD pins. It is fully compatible with Renesas E2 studio and CS+ IDEs, and supports breakpoints, watchpoints, real-time variable monitoring, and flash programming. No external JTAG adapter is required-the debug interface is integrated and enabled by default in the reset configuration.
Is the R7F100GLH2DFB#AA0 pin-compatible with other RL78/G23 variants in the same 64-pin LFQFP package?
Yes, all RL78/G23 64-pin LFQFP variants-including R7F100GLH2DFB#AA0, R7F100GLJ2DFB#AA0, and R7F100GLK2DFB#AA0-share identical pinouts, electrical characteristics, and peripheral mapping. Memory size differences (128 KB vs. 192 KB vs. 256 KB) do not affect pin function assignment, enabling direct hardware compatibility and firmware scalability across the family.
