Product details
Overview
R7F100GLJ3CFA#AA0 from Renesas is a 64-pin, industrial-grade RL78/G23 16-bit MCU with 512 KB code flash, 8 KB data flash, and 48 KB RAM, operating from 1.6–5.5 V. It delivers true low-power operation (41 µA/MHz active, 210 nA data retention), integrates capacitive touch sensing (CTSU2L), RTC, 16-bit TAU timers, UARTA/IICA/SAU interfaces, and supports SNOOZE mode for autonomous peripheral sequencing.
For engineers reviewing the R7F100GLJ3CFA#AA0 datasheet, R7F100GLJ3CFA#AA0 pinout, R7F100GLJ3CFA#AA0 application, or R7F100GLJ3CFA#AA0 equivalent, key selection criteria include its 64-pin LQFP-0.65mm package, -40°C to +105°C industrial temperature rating, integrated CTSU2L for up to 64-key mutual-capacitance touch, and hardware-accelerated SNOOZE mode sequencer for ultra-low-power sensor polling without CPU wake-up.
Technical Context
The R7F100GLJ3CFA#AA0 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). Its SNOOZE mode sequencer executes up to 32 preconfigured commands-including ADC sampling, comparator comparison, and timer-triggered actions-without CPU, RAM, or flash activation, enabling deterministic sub-µA background operation.
Peripheral integration includes a Logic and Event Link Controller (ELCL) for configurable signal routing between peripherals, a Data Transfer Controller (DTC) with chain transfer support, and dual-voltage I/O (1.8/2.5/3.0 V compatible) with N-ch open-drain options. The CTSU2L unit operates across the full 1.8–5.5 V supply range and supports both self- and mutual-capacitance configurations.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GLK3CFA#AA0 | Same 64-pin LQFP package, identical peripherals, but 384 KB code flash / 32 KB RAM | Lower memory configuration suits cost-sensitive designs with smaller firmware footprints or reduced data buffering needs | Select when application firmware size is <384 KB and RAM usage ≤32 KB - reduces BOM cost without sacrificing peripheral set or package compatibility |
| R7F100GMJ3CFA#AA0 | 80-pin LQFP variant with same 512 KB/48 KB memory, adds 4 more UARTA channels and 2 additional SAU channels | Required for systems needing ≥6 serial interfaces (e.g., multi-protocol gateway with Modbus + CAN FD bridge) | Choose only if pin count expansion is needed for additional UART/I²C/SAU channels - not a drop-in replacement due to different footprint and pinout |
Compared with R7F100GLK3CFA#AA0, the R7F100GLJ3CFA#AA0 provides higher memory headroom for complex control algorithms and larger data buffers; versus R7F100GMJ3CFA#AA0, it offers identical core performance and memory in a smaller, lower-cost 64-pin package - ideal for space-constrained industrial controls where full 80-pin I/O is unnecessary.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GLJ3CFA#AA0?
The R7F100GLJ3CFA#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, the minimum instruction execution time is 0.03125 µs. The device maintains timing specifications over the entire industrial temperature range (-40°C to +105°C) when operated within these voltage and frequency limits.
Does the R7F100GLJ3CFA#AA0 support hardware debugging, and what interface is used?
Yes, the R7F100GLJ3CFA#AA0 supports on-chip debugging via the dedicated TOOL0 and TOOLRxD/TOOLTxD pins, implementing Renesas' standard FINE (Fast In-circuit Emulator) debug interface. This enables full breakpoint, watchpoint, and real-time variable inspection capabilities using Renesas E2 or E2 Lite debuggers without requiring additional SWD/JTAG pins - preserving I/O for application use.
How many capacitive touch channels does the CTSU2L unit support on the R7F100GLJ3CFA#AA0, and what configurations are available?
The CTSU2L unit on the R7F100GLJ3CFA#AA0 supports up to 32 self-capacitance channels (one per pin) or up to 64 mutual-capacitance channels (8 × 8 matrix). It operates across the full 1.8–5.5 V supply range and includes built-in noise cancellation, auto-calibration, and threshold adjustment - enabling robust touch performance in noisy industrial environments without external components.
What is the endurance specification for the data flash memory in the R7F100GLJ3CFA#AA0, and how is wear leveling handled?
The data flash memory in the R7F100GLJ3CFA#AA0 is rated for 1,000,000 write/erase cycles (typical). Wear leveling is not implemented in hardware; it must be managed in firmware using Renesas-provided data flash library functions that support background operation (BGO) and sector management. The 8 KB data flash is organized in 2 KB blocks, allowing selective erasure to extend effective lifetime.
Can the R7F100GLJ3CFA#AA0 operate from a 3.3 V supply while interfacing with 1.8 V logic peripherals?
Yes, the R7F100GLJ3CFA#AA0 supports mixed-voltage I/O operation. Its port pins can be configured for 1.8 V, 2.5 V, or 3.0 V logic levels independently of the 1.6–5.5 V VDD supply. When powered at 3.3 V, selected pins may be set to 1.8 V I/O mode - enabling direct, level-shift-free interfacing with 1.8 V sensors, memories, or communication ICs without external translators.
