Product details
Overview
R7F100GLH2DFA#AA0 from Renesas is a 64-pin, consumer-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 rich peripherals including 16-bit timers, 12-bit ADC (26 channels), UART/LIN, I²C, and SPI - deployed in battery-powered home appliances and smart sensors.
For engineers reviewing the R7F100GLH2DFA#AA0 datasheet, R7F100GLH2DFA#AA0 pinout, R7F100GLH2DFA#AA0 application, or R7F100GLH2DFA#AA0 equivalent, key selection criteria include its 64-pin LFQFP-0.5 mm package, -40°C to +85°C temperature grade, 192 KB flash/24 KB RAM configuration, and support for SNOOZE mode sequencer and CTSU2L capacitive sensing without CPU intervention.
Technical Context
The R7F100GLH2DFA#AA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). Its power management includes HALT, STOP, and SNOOZE modes, with wake-up from STOP in under 4 µs and background data flash rewriting via BGO.
Peripheral integration centers on event-driven operation: the Event Link Controller (ELCL) enables hardware-triggered signal routing between modules (e.g., ADC → DTC → UART), while the SNOOZE mode sequencer executes up to 32 low-power processing steps using 21 command types - eliminating CPU wake-ups for periodic sensor polling or LED dimming sequences.

FAQ
What is the maximum operating frequency and corresponding current consumption of the R7F100GLH2DFA#AA0?
The R7F100GLH2DFA#AA0 operates up to 32 MHz using the high-speed on-chip oscillator (±1.0% accuracy). At this frequency and VDD = 3.3 V, typical active current is 41 µA per MHz - resulting in ~1.3 mA total at full speed. In STOP mode, current drops to 0.52 µA, and data retention for 4 KB RAM consumes just 210 nA.
Does the R7F100GLH2DFA#AA0 support hardware-based capacitive touch sensing, and how many keys can it handle?
Yes, the R7F100GLH2DFA#AA0 integrates the CTSU2L capacitive touch sensing unit. It supports up to 32 keys in self-capacitance mode (one pin per key) or up to 64 keys in mutual capacitance mode (8×8 matrix), with built-in noise cancellation and automatic drift compensation - all implemented in hardware without CPU involvement.
Can the R7F100GLH2DFA#AA0 perform flash memory writes while executing code from flash?
Yes, the R7F100GLH2DFA#AA0 supports Background Operation (BGO) for data flash. Code can execute from program memory while simultaneously rewriting the 8 KB data flash - enabling real-time parameter storage, firmware logging, or over-the-air update staging without interrupting application logic.
What debug and programming interfaces are available on the R7F100GLH2DFA#AA0?
The R7F100GLH2DFA#AA0 supports on-chip debugging via the dedicated TOOLRxD/TOOLTxD pins (P11/P12) compatible with Renesas E2 studio and CS+ IDE. It also features SWD (Serial Wire Debug) through the RESET pin and optional JTAG via P10–P12, with full support for flash programming, breakpoint setting, and real-time variable monitoring.
Is the R7F100GLH2DFA#AA0 pin-compatible with other RL78/G23 variants in the same 64-pin LFQFP package?
Yes, all RL78/G23 MCUs in the 64-pin LFQFP-0.5 mm package (e.g., R7F100GLF2DFA#AA0, R7F100GLG2DFA#AA0, R7F100GLH2DFA#AA0, R7F100GLJ2DFA#AA0) share identical pinouts and electrical characteristics. Firmware and PCB layouts are interchangeable across these variants - only flash/RAM capacities and minor peripheral enablement differ.
