Product details
Overview
R7F100GLH3CFB#AA0 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 supports real-time clock, 16-bit timers, 12-bit ADC (26 channels), and multiple serial interfaces for embedded control in battery-powered industrial sensors and HMI panels.
For engineers reviewing the R7F100GLH3CFB#AA0 datasheet, R7F100GLH3CFB#AA0 pinout, R7F100GLH3CFB#AA0 application, or R7F100GLH3CFB#AA0 equivalent, key selection criteria include its 64-pin LFQFP-0.50 mm package, -40°C to +105°C industrial temperature rating, 192 KB flash/24 KB RAM memory configuration, and support for SNOOZE mode sequencer and CTSU2L capacitive sensing without CPU intervention.
Technical Context
The R7F100GLH3CFB#AA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed oscillator) to 30.5 µs (32.768 kHz subsystem clock). Its SNOOZE mode sequencer (SMS) executes up to 32 low-power processes using 21 command types-enabling sensor polling or periodic wake-up without CPU, flash, or RAM activation.
Peripheral integration includes Logic and Event Link Controller (ELCL) for configurable event routing between functions, Data Transfer Controller (DTC) with chain transfer, and dual-voltage I/O (1.8/2.5/3.0 V compatible) with N-ch open-drain ports. The capacitive sensing unit (CTSU2L) operates in self- or mutual-capacitance mode, supporting up to 32 single-key or 64 matrix-key configurations under 1.8–5.5 V.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GLH3CFB#AA0?
The R7F100GLH3CFB#AA0 supports up to 32 MHz operation using its 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 maintains timing specifications across -40°C to +105°C ambient temperatures, making it suitable for high-reliability industrial environments where thermal stability is critical. The R7F100GLH3CFB#AA0 does not require external clock sources to achieve maximum performance.
Does the R7F100GLH3CFB#AA0 support hardware-based capacitive touch sensing, and what configurations are available?
Yes, the R7F100GLH3CFB#AA0 integrates the CTSU2L capacitive 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) modes. It operates under 1.8–5.5 V VDD and includes built-in noise cancellation, auto-calibration, and scan result averaging. The R7F100GLH3CFB#AA0 uses dedicated pins like P30 (TSCAP) and P60–P62 (CCD04–CCD06) for optimal signal integrity-no external components are required beyond decoupling capacitors.
How many serial communication interfaces does the R7F100GLH3CFB#AA0 provide, and which protocols are supported?
The R7F100GLH3CFB#AA0 provides up to 10 I²C/Simplified I²C channels, 6 UART/UARTA channels (with LIN-bus protocol support), and 8 CSI (SPI-compatible) channels. These interfaces are implemented in the Serial Array Unit (SAU) and Serial Interface modules, with flexible pin mapping via the Peripheral I/O Redirection Register (PIOR). The R7F100GLH3CFB#AA0 supports simultaneous operation of multiple protocols-for example, I²C for sensor reading, UARTA for Modbus RTU, and CSI for display driver communication-without resource conflict.
What low-power modes are available on the R7F100GLH3CFB#AA0, and how do they differ in wake-up capability and current draw?
The R7F100GLH3CFB#AA0 offers HALT, STOP, and SNOOZE modes. HALT halts CPU but keeps peripherals running (typ. 120 µA). STOP disables clocks to most blocks except RTC and LVD (typ. 0.27 µA). SNOOZE enables autonomous peripheral operation (e.g., ADC sampling → compare → GPIO toggle) with CPU, flash, and RAM powered down (typ. 0.9 µA). Wake-up from STOP occurs in ≤3.5 µs via external interrupt or RTC alarm; SNOOZE wake-up is immediate upon sequence completion. All modes preserve 24 KB RAM content.
Is the R7F100GLH3CFB#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-0.50 mm package-including R7F100GLF3CFB#AA0, R7F100GLG3CFB#AA0, R7F100GLH3CFB#AA0, R7F100GLJ3CFB#AA0, R7F100GLK3CFB#AA0, and R7F100GLL3CFB#AA0-share identical pinouts, electrical characteristics, and peripheral mappings. Memory size (flash/RAM) and oscillator options vary by part number, but PCB layout, power delivery, and signal routing remain fully interchangeable across this 64-pin family.
