FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F100LCGFA#50?
The R5F100LCGFA#50 operates up to 32 MHz using its high-speed on-chip oscillator. At this frequency, typical active current is 66 μA per MHz, resulting in ~2.1 mA total at 32 MHz under standard conditions. Its ultra-low-power STOP mode draws just 0.57 μA with RTC and LVD active-critical for battery-powered deployments where R5F100LCGFA#50 serves as the primary system controller.
Does the R5F100LCGFA#50 support hardware debugging without external tools?
Yes, the R5F100LCGFA#50 includes an on-chip debug interface accessible via P14 (TOOLRxD) and P15 (TOOLTxD) pins. This allows full flash programming, breakpoint setting, and real-time variable inspection using only a UART-to-USB converter-no JTAG emulator required. The debug functionality remains fully operational throughout all low-power modes except HALT, making R5F100LCGFA#50 highly suitable for field firmware updates and validation.
How many analog input channels does the R5F100LCGFA#50 support, and what is their resolution?
The R5F100LCGFA#50 features a 10-bit successive-approximation ADC with up to 26 configurable analog input channels (ANI0–ANI25), of which 8 are routed to P00–P07. It supports internal 1.45 V reference and external AVREFP/AVREFM inputs for ratiometric or absolute measurements. The ADC operates across the full 1.6–5.5 V supply range, enabling direct sensor interfacing without signal conditioning-key for compact R5F100LCGFA#50-based sensor nodes.
What packaging and temperature grade does the R5F100LCGFA#50 have?
The R5F100LCGFA#50 uses a 64-pin LQFP package (12 × 12 mm, 0.65-mm pitch) with JEDEC-standard PLQP0064JA-A footprint. It is rated for industrial operation from -40°C to +105°C (G-grade), verified per Renesas qualification standards. This makes R5F100LCGFA#50 appropriate for under-hood automotive modules, factory-floor controllers, and outdoor utility equipment where thermal robustness is mandatory.
Can the R5F100LCGFA#50 perform data flash writes while executing application code?
Yes, the R5F100LCGFA#50 supports Background Operation (BGO) for data flash memory. When enabled, the MCU can execute instructions from code flash while simultaneously rewriting data flash sectors-enabling seamless firmware parameter updates, event logging, or calibration storage without interrupting real-time tasks. This capability is implemented in hardware and requires no CPU polling, making R5F100LCGFA#50 ideal for mission-critical systems demanding continuous operation.
