Product details
Overview
R7F100GLK2DFA#AA0 from Renesas is a 64-pin, 512-KB flash, 48-KB RAM RL78/G23 16-bit MCU operating at 1.6–5.5 V, featuring ultra-low-power operation (41 µA/MHz), 210-nA data retention, integrated capacitive touch sensing (CTSU2L), and dual 16-bit timer arrays - deployed in battery-powered industrial HMI and sensor node control applications.
For engineers reviewing the R7F100GLK2DFA#AA0 datasheet, R7F100GLK2DFA#AA0 pinout, R7F100GLK2DFA#AA0 application, or R7F100GLK2DFA#AA0 equivalent, key selection criteria include its 64-pin LFQFP-0.5 mm package, -40°C to +85°C consumer-grade temperature range, and support for SNOOZE mode sequencer-driven autonomous peripheral operation without CPU wake-up.
Technical Context
The R7F100GLK2DFA#AA0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting configurable instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). It integrates a SNOOZE mode sequencer (SMS) capable of executing up to 32 sequential commands across 21 instruction types to manage periodic analog sensing and I/O polling while keeping CPU, flash, and RAM powered down.
Peripheral integration includes a Logic and Event Link Controller (ELCL) enabling hardware-triggered signal routing between peripherals, a Data Transfer Controller (DTC) supporting chain transfers, and dual serial interface sets: up to 10 I²C/Simplified I²C channels and up to 6 UART/UARTA/LIN channels - all configurable via peripheral I/O redirection registers (PIOR).

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GLL2DFA#AA0 | Same 64-pin LFQFP package and 512-KB flash, but 32-KB RAM (vs. 48 KB); identical peripheral set and power specs | Lower RAM margin suitable for simpler control tasks without large buffers or complex protocol stacks | Select when application memory footprint fits within 32 KB RAM and cost optimization is prioritized |
| R7F100GMK2DFA#AA0 | 80-pin LQFP variant with same 512-KB flash/48-KB RAM, adds 4 extra ADC channels and 2 additional UARTA channels | Required when system needs >26 ADC inputs or >6 UART interfaces - e.g., multi-sensor gateway or industrial protocol bridge | Choose only if pin count and peripheral expansion justify larger footprint and layout redesign |
Compared with R7F100GLL2DFA#AA0, the R7F100GLK2DFA#AA0 provides 16 KB more RAM for larger firmware or data buffering; versus R7F100GMK2DFA#AA0, it offers identical core performance in a smaller, lower-cost 64-pin package - ideal for space-constrained, RAM-intensive consumer and industrial edge nodes.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GLK2DFA#AA0?
The R7F100GLK2DFA#AA0 supports up to 32 MHz operation using the high-speed on-chip oscillator, with guaranteed functionality across its full 1.6 V to 5.5 V supply 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 timing, with the same voltage range.
Does the R7F100GLK2DFA#AA0 support hardware-accelerated cryptographic functions?
No, the R7F100GLK2DFA#AA0 does not include dedicated cryptographic accelerators such as AES or SHA engines. Its security features are limited to flash memory protection (block erase/write prohibition, boot swapping, flash shield window) and debug lock. For applications requiring hardware crypto, Renesas' RA family or RL78/G23's successor lines should be evaluated.
How many capacitive touch channels can the R7F100GLK2DFA#AA0 support in mutual-capacitance mode?
The R7F100GLK2DFA#AA0 supports up to 64 keys in mutual-capacitance mode using an 8 × 8 pin matrix configuration via its CTSU2L unit. This requires dedicating 16 GPIO pins (8 for X-lines, 8 for Y-lines), with full noise immunity and auto-calibration handled in hardware - no external components or firmware compensation needed.
Is the R7F100GLK2DFA#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-0.5 mm package (e.g., R7F100GLF2DFA#AA0, R7F100GLG2DFA#AA0, R7F100GLH2DFA#AA0, R7F100GLJ2DFA#AA0, R7F100GLK2DFA#AA0, R7F100GLL2DFA#AA0, R7F100GLN2DFA#AA0) share identical pinouts and electrical characteristics - enabling drop-in replacement based on flash/RAM configuration and temperature grade.
What debug interface does the R7F100GLK2DFA#AA0 use, and what are the required pins?
The R7F100GLK2DFA#AA0 uses Renesas' on-chip debugging interface accessible via the TOOL0 (pin 40), TOOLRxD (P11), and TOOLTxD (P12) pins - compatible with E2 studio and Renesas Flash Programmer. No external debug probe is required beyond standard SWD/JTAG adapters supporting RL78 protocols; the interface supports full breakpoint, watchpoint, and real-time variable monitoring during active execution.
