It delivers ultra-low power consumption (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (up to 64 keys), and dual-clock domain operation for battery-powered HMI and sensor node applications.
For engineers reviewing the R7F100GLJ3CFA#BA0 datasheet, R7F100GLJ3CFA#BA0 pinout, R7F100GLJ3CFA#BA0 application, or R7F100GLJ3CFA#BA0 equivalent, key selection criteria include its 64-pin LQFP-0.65mm package, -40°C to +105°C industrial temperature rating, SNOOZE mode sequencer for autonomous low-power sensing, and hardware-accelerated CTSU2L capacitive touch engine.
Technical Context
The R7F100GLJ3CFA#BA0 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 power architecture includes HALT, STOP, and SNOOZE modes, with dedicated hardware sequencer (SMS) enabling up to 32 autonomous operations without CPU wake-up.
Peripheral integration includes 16-bit TAU timers (12 channels), RTC with alarm and correction, 12-bit ADC (26 channels), 8-bit DAC (2 channels), 2 comparators, and flexible serial interfaces: up to 10 I²C/Simplified I²C, 6 UART/UARTA (LIN-capable), and 8 CSI/SPI channels - all configurable via peripheral I/O redirection register (PIOR).

FAQ
What is the maximum operating frequency and corresponding instruction cycle time for the R7F100GLJ3CFA#BA0?
The R7F100GLJ3CFA#BA0 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 confirmed in the RL78/G23 datasheet (R01DS0395EJ0140) Section 1.1 under "RL78 CPU core" specifications and applies directly to the R7F100GLJ3CFA#BA0 as a member of the 512 KB/48 KB memory variant group.
Does the R7F100GLJ3CFA#BA0 support hardware-based capacitive touch sensing, and what configurations are available?
Yes, the R7F100GLJ3CFA#BA0 integrates the CTSU2L capacitive touch sensing unit supporting both self-capacitance (up to 32 keys on single pins) and mutual capacitance (8×8 matrix, up to 64 keys). It operates from 1.8–5.5 V and includes built-in noise cancellation - all documented in Section 1.1 "Capacitive sensing unit" of the R01DS0395EJ0140 datasheet for the RL78/G23 family, which explicitly covers the R7F100GLJ3CFA#BA0.
What are the supported low-power modes for the R7F100GLJ3CFA#BA0, and how does SNOOZE mode differ from STOP mode?
The R7F100GLJ3CFA#BA0 supports HALT, STOP, and SNOOZE modes. STOP mode shuts down the CPU and most peripherals (0.34 µA typical), while SNOOZE mode keeps selected peripherals (CTSU2L, ADC, RTC, SMS) active to execute pre-programmed sequences autonomously - consuming ~1.2 µA - without waking the CPU or accessing flash/RAM. This distinction is defined in Section 1.1 "Ultra-low power consumption technology" of the R01DS0395EJ0140 datasheet.
Can the R7F100GLJ3CFA#BA0 perform background data flash writes while executing code from main flash memory?
Yes, the R7F100GLJ3CFA#BA0 supports Background Operation (BGO) for its 8 KB data flash memory, allowing full program execution from code flash during data flash erase/write cycles. This capability is specified in Section 1.1 "Data flash memory" of the R01DS0395EJ0140 datasheet and applies to all RL78/G23 variants including the R7F100GLJ3CFA#BA0.
What is the pin count, package type, and industrial qualification status of the R7F100GLJ3CFA#BA0?
The R7F100GLJ3CFA#BA0 is a 64-pin device in plastic LQFP (12 × 12 mm, 0.65-mm pitch) package, qualified for industrial ambient temperature range (-40°C to +105°C), as indicated by the 'C' in the part number and confirmed in Table 1-1 "List of Ordering Part Numbers" (Page 6) and Figure 1-1 of the R01DS0395EJ0140 datasheet.
