Product details
Overview
R7F100GLJ3CFB#AA0 from Renesas is a 64-pin LFQFP, 512-KB code flash, 32-KB RAM RL78/G23 16-bit MCU operating from 1.6 to 5.5 V, featuring 210-nA data retention current, 41-µA/MHz active current, and integrated capacitive touch sensing (CTSU2L) for industrial HMI applications.
For engineers reviewing the R7F100GLJ3CFB#AA0 datasheet, R7F100GLJ3CFB#AA0 pinout, R7F100GLJ3CFB#AA0 application, or R7F100GLJ3CFB#AA0 equivalent, key selection criteria include ultra-low-power STOP/SNOOZE modes, 26-channel 12-bit ADC with internal reference, dual 8-bit DACs, and hardware-based event link controller (ELCL) for autonomous peripheral coordination without CPU intervention.
Technical Context
The R7F100GLJ3CFB#AA0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs at 32 MHz high-speed mode or 30.5 µs at 32.768 kHz ultra-low-speed mode). It integrates a SNOOZE mode sequencer (SMS) supporting 32 sequential commands across 21 operations, enabling sensor polling and threshold evaluation while retaining RAM and avoiding full wake-up.
Its peripheral set includes a 26-channel 12-bit A/D converter with internal 1.48-V reference and temperature sensor, two 8-bit D/A converters with real-time output capability, and an ELCL that routes event signals between peripherals (e.g., timer overflow → ADC trigger → interrupt) using programmable logic and flip-flop circuits - all operable in low-power states.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GLJ3CFB#AA0?
The R7F100GLJ3CFB#AA0 operates up to 32 MHz using the high-speed on-chip oscillator, supported across its full 1.6 V to 5.5 V VDD 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, maintaining functionality down to 1.6 V.
Does the R7F100GLJ3CFB#AA0 support hardware-based capacitive touch sensing, and what configurations are available?
Yes, the R7F100GLJ3CFB#AA0 integrates the CTSU2L capacitive sensing unit supporting both self-capacitance (up to 32 keys on single pins) and mutual capacitance (up to 64 keys in 8×8 matrix). It operates at VDD = 1.8–5.5 V, includes built-in noise suppression, and supports automatic calibration - eliminating need for external touch controller ICs in industrial HMI designs.
How many serial communication interfaces does the R7F100GLJ3CFB#AA0 provide, and which protocols are supported?
The R7F100GLJ3CFB#AA0 provides up to 10 I²C/Simplified I²C channels, 6 UARTA channels (with LIN-bus support), and 8 CSI (SPI-compatible) channels. All are implemented in the Serial Array Unit (SAU) with independent clock sources and buffer control, enabling concurrent multi-protocol communication without resource contention.
What power-saving modes are available on the R7F100GLJ3CFB#AA0, and what is the lowest current draw achievable?
The R7F100GLJ3CFB#AA0 offers HALT, STOP, and SNOOZE modes. In STOP mode with 4 KB RAM retention, current drops to 210 nA; full 32 KB RAM retention draws 320 nA. SNOOZE mode enables autonomous peripheral operation (e.g., ADC sampling, comparison) at ~1.5 µA - significantly lower than full active mode (41 µA/MHz) while preserving responsiveness.
Is the R7F100GLJ3CFB#AA0 pin-compatible with other RL78/G23 variants in the same 64-pin LFQFP package?
Yes, all RL78/G23 devices in the 64-pin LFQFP package (FB suffix) - including R7F100GLF3CFB#AA0 through R7F100GLN3CFB#AA0 - share identical pinouts and electrical characteristics. This allows direct substitution within the same memory/feature tier (e.g., 512-KB flash variants) without PCB redesign, provided peripheral configuration and firmware are compatible.
