FAQ
What is the maximum operating frequency and voltage range supported by the R5F52108CGFM#50?
The R5F52108CGFM#50 operates at up to 50 MHz when supplied with 2.7–5.5 V, 32 MHz at 1.8–2.7 V, and 20 MHz at 1.62–1.8 V. Its voltage range spans 1.62 V to 5.5 V, enabling direct interfacing with diverse power domains including battery-backed and industrial 3.3 V/5 V systems. This flexibility eliminates level-shifting needs in mixed-voltage designs.
Does the R5F52108CGFM#50 support IEC60730 Class B compliance out of the box?
Yes, the R5F52108CGFM#50 includes dedicated hardware features for IEC60730 Class B compliance: self-diagnostic routines for the A/D converter and clock accuracy measurement circuit (CAC), analog input disconnection detection, RAM test assist, and independent watchdog timer (IWDT) with dedicated oscillator. These are documented in the RX210 hardware manual and require minimal firmware integration to meet certification requirements.
What package type and pin count does the R5F52108CGFM#50 use?
The R5F52108CGFM#50 uses the PLQP0064KB-A package: a 64-pin LQFP with 10 × 10 mm body size and 0.5-mm pitch. It provides 48 general-purpose I/O pins, 2 of which (P16, P17) are 5-V tolerant-making it suitable for interfacing with legacy 5 V logic or industrial sensors without external level shifters.
How many A/D and D/A converter channels does the R5F52108CGFM#50 integrate?
The R5F52108CGFM#50 integrates a 12-bit successive-approximation A/D converter (S12AD) with 16 input channels and a minimum conversion time of 1.0 μs, plus two independent 10-bit D/A converters (DA0, DA1) with output range 0 V to VREFH. The ADC supports sample-and-hold on three channels and synchronized sampling across multiple inputs-critical for motor current sensing and power quality analysis.
Is on-chip debugging supported for the R5F52108CGFM#50, and what tools are compatible?
Yes, the R5F52108CGFM#50 supports on-chip debugging via the FINE interface, fully compatible with Renesas' E1 emulator. This enables non-intrusive real-time debugging, flash programming, and trace functionality without consuming dedicated debug pins-preserving all 64 LQFP pins for application use. No SWD/JTAG header is required.
