FAQ
What is the maximum operating frequency and performance rating of the R5F101PFDFB#V0?
The R5F101PFDFB#V0 operates at up to 32 MHz and delivers 41 DMIPS (Dhrystone MIPS) performance. This is achieved using the RL78 CPU core's 3-stage pipeline and high-speed on-chip oscillator with ±1.0% accuracy across 1.8–5.5 V and –20°C to +85°C. Its minimum instruction execution time is 0.03125 μs at full speed, making it suitable for deterministic real-time control loops.
Does the R5F101PFDFB#V0 include on-chip data flash memory?
No, the R5F101PFDFB#V0 does not include on-chip data flash memory. Per Renesas' part numbering convention, the "101" prefix indicates data flash is omitted. The device contains only 64 KB of code flash and 4 KB of RAM. For applications requiring nonvolatile parameter storage, external EEPROM or code flash emulation must be implemented.
What low-power modes are supported by the R5F101PFDFB#V0, and what are their typical current draws?
The R5F101PFDFB#V0 supports HALT mode (66 μA/MHz), STOP mode (0.57 μA with RTC and LVD active), and SNOOZE mode (selective peripheral wake-up). These modes are hardware-controlled and require no software overhead to enter/exit. STOP mode is especially valuable for battery-powered devices needing calendar-aware wake-up without external RTC.
Which serial communication interfaces are available on the R5F101PFDFB#V0?
The R5F101PFDFB#V0 integrates UART/UART (2 channels, LIN-bus supported), CSI (Simplified SPI, up to 8 channels), and I²C/Simplified I²C (up to 10 channels). All are multiplexed on GPIO pins and configurable per application needs. UART0 and UART1 each support automatic LIN break detection and sync field handling, easing automotive subsystem integration.
What is the ADC resolution and channel count supported by the R5F101PFDFB#V0?
The R5F101PFDFB#V0 features a 10-bit successive-approximation A/D converter with up to 16 analog input channels. It includes an internal 1.45 V reference voltage and supports temperature sensor readout. Input voltage range is tied to VDD (1.6–5.5 V), eliminating need for external reference in many sensing applications.
Is the R5F101PFDFB#V0 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F101PFDFB#V0 is pin-compatible with all other RL78/G13 devices in the 64-pin LFQFP (FB) package, including R5F100PFDFB#V0 and R5F101PGAFB#V0. Pin functions, power/ground locations, and reset configuration are identical - enabling drop-in replacement for memory or feature scaling without PCB revision.
