Product details
Overview
R7F100GLN3CFB#AA0 from Renesas is an RL78/G23 16-bit microcontroller with 512 KB code flash, 48 KB RAM, and 64-pin LFQFP (0.50-mm pitch) package operating from 1.6–5.5 V. It delivers true low-power operation (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (up to 64 keys), and dual-clock domain support for industrial control and sensor interface applications.
For engineers reviewing the R7F100GLN3CFB#AA0 datasheet, R7F100GLN3CFB#AA0 pinout, R7F100GLN3CFB#AA0 application, or R7F100GLN3CFB#AA0 equivalent, key selection criteria include its 64-pin LFQFP footprint, -40°C to +105°C industrial temperature grade, integrated SNOOZE mode sequencer for autonomous low-power sensing, and hardware-accelerated CTSU2L capacitive touch unit.
Technical Context
The R7F100GLN3CFB#AA0 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 power management includes HALT, STOP, and SNOOZE modes - the latter enabling autonomous peripheral sequencing without CPU wake-up.
Peripheral integration includes up to 16× 16-bit timers, 1× real-time clock with alarm and correction, 8–26-channel 12-bit ADC with internal 1.48 V reference and temperature sensor, 2× 8-bit DACs, 2× comparators, and flexible serial interfaces: up to 10× I²C/Simplified I²C, 6× UART/UARTA (LIN-capable), and 8× CSI (SPI-compatible). The CTSU2L unit supports both self- and mutual-capacitance touch sensing.

FAQ
What is the maximum operating frequency and corresponding instruction cycle time for the R7F100GLN3CFB#AA0?
The R7F100GLN3CFB#AA0 supports up to 32 MHz operation using the high-speed on-chip oscillator, delivering a minimum instruction execution time of 0.03125 µs. This timing is achievable across the full industrial temperature range (-40°C to +105°C) and 1.6–5.5 V supply, with oscillator accuracy guaranteed at ±1.0%.
Does the R7F100GLN3CFB#AA0 support hardware-based capacitive touch sensing, and what configurations are available?
Yes, the R7F100GLN3CFB#AA0 integrates the CTSU2L capacitive touch sensing unit. It supports self-capacitance mode (up to 32 keys on single pins) and mutual-capacitance matrix mode (up to 64 keys in 8×8 configuration), both operating under VDD = 1.8–5.5 V. No external touch controller IC is required.
What power-saving modes does the R7F100GLN3CFB#AA0 offer, and how low is the current draw in data retention mode?
The R7F100GLN3CFB#AA0 offers HALT, STOP, and SNOOZE modes. In STOP mode with 4 KB RAM retention enabled, it draws only 210 nA - verified across -40°C to +105°C. SNOOZE mode allows autonomous peripheral sequencing (e.g., ADC sampling → compare → GPIO toggle) without waking the CPU or accessing flash/RAM.
Can the R7F100GLN3CFB#AA0 execute code while rewriting its data flash memory?
Yes, the R7F100GLN3CFB#AA0 supports background operation (BGO) for its 8 KB data flash memory. Instructions can be fetched and executed from code flash while data flash is being rewritten - essential for reliable firmware updates and non-volatile parameter storage in live systems.
What is the pin count, package type, and industrial temperature rating of the R7F100GLN3CFB#AA0?
The R7F100GLN3CFB#AA0 uses a 64-pin LFQFP package (10 × 10 mm, 0.50-mm pitch) and is rated for industrial operation from -40°C to +105°C (denoted by "3C" in the part number). The "#AA0" suffix indicates tray packaging per JEDEC standard.
