Product details
Overview
R7F100GLK2DFA#BA0 from Renesas is a 64-pin, 512 KB code flash, 48 KB RAM RL78/G23 16-bit microcontroller operating from 1.6–5.5 V, featuring ultra-low power consumption (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (CTSU2L), and dual 16-bit timer arrays for motor control and sensor interfacing in industrial HMI applications.
For engineers reviewing the R7F100GLK2DFA#BA0 datasheet, R7F100GLK2DFA#BA0 pinout, R7F100GLK2DFA#BA0 application, or R7F100GLK2DFA#BA0 equivalent, key selection criteria include its 64-pin LFQFP-0.5 mm package, -40 to +85°C consumer-grade temperature range, 512 KB/48 KB memory configuration, and support for SNOOZE mode sequencer and ELCL event linking without CPU intervention.
Technical Context
The R7F100GLK2DFA#BA0 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 21-instruction SNOOZE mode sequencer (SMS) that executes low-power background tasks independently of CPU, flash, or RAM.
Peripheral integration includes Logic and Event Link Controller (ELCL) for hardware-triggered signal routing between peripherals, 16-channel 16-bit Timer Array Unit (TAU), 10-channel I²C/Simplified I²C, 6-channel UARTA with LIN support, and 26-channel 12-bit A/D converter with internal 1.48 V reference and temperature sensor.

FAQ
What is the maximum operating frequency and corresponding current consumption of the R7F100GLK2DFA#BA0?
The R7F100GLK2DFA#BA0 operates at up to 32 MHz using the high-speed on-chip oscillator. At this frequency, it draws 41 µA per MHz under typical conditions (VDD = 3.3 V, TA = 25°C), resulting in ~1.31 mA total active current. This value is confirmed in Section 1.1 of the R01DS0395EJ0140 datasheet and applies specifically to the R7F100GLK2DFA#BA0's 512 KB flash configuration.
Does the R7F100GLK2DFA#BA0 support hardware-based capacitive touch sensing without external components?
Yes, the R7F100GLK2DFA#BA0 integrates the CTSU2L capacitive sensing unit capable of self-capacitance (up to 32 keys) and mutual-capacitance (up to 64 keys) operation. It requires no external RC networks or dedicated touch controller ICs - only electrode traces on the PCB. This functionality is documented in Section 1.1 and confirmed for all RL78/G23 variants including R7F100GLK2DFA#BA0.
What package type and pin pitch does the R7F100GLK2DFA#BA0 use?
The R7F100GLK2DFA#BA0 uses a 64-pin LFQFP package with 0.50-mm pitch and 10 × 10 mm body size (Renesas code PLQP0064KB-C / PLQP0064KL-A). The #BA0 suffix denotes tray packaging. This is explicitly defined in Table 1-1 (Page 6) of the R01DS0395EJ0140 datasheet for ordering part R7F100GLK2DFA#BA0.
Can the R7F100GLK2DFA#BA0 operate from a single 1.8 V supply, and what peripherals remain functional?
Yes, the R7F100GLK2DFA#BA0 supports operation from 1.6–5.5 V, including 1.8 V. At 1.8 V, the high-speed on-chip oscillator (32 MHz option) is disabled; maximum CPU speed is 16 MHz. All core peripherals - CTSU2L, 12-bit ADC, UARTA, I²C, TAU, RTC - remain fully operational per Section 1.1 and electrical characteristics tables in R01DS0395EJ0140.
Is the R7F100GLK2DFA#BA0 pin-compatible with other RL78/G23 64-pin variants such as R7F100GLL2DFA#BA0?
Yes, all RL78/G23 64-pin variants in the LFQFP-0.5 mm package - including R7F100GLK2DFA#BA0, R7F100GLL2DFA#BA0, and R7F100GLN2DFA#BA0 - share identical pinouts and electrical characteristics. Differences are limited to memory size (512 KB vs. 384 KB vs. 768 KB) and are transparent to PCB layout and signal routing, as confirmed in Tables 1-1 and 1-3 of R01DS0395EJ0140.
