FAQ

What is the maximum operating frequency of the R5F10PGHCLFB#15?

The R5F10PGHCLFB#15 operates at a maximum CPU clock frequency of 32 MHz. This speed is achieved using the on-chip high-speed oscillator (HOCO) or an external crystal/resonator. At 32 MHz, the R5F10PGHCLFB#15 delivers 31.25 ns instruction cycle time for time-critical tasks such as motor commutation and LIN frame transmission, while maintaining full peripheral functionality including ADC and RTC.

Does the R5F10PGHCLFB#15 support LIN 2.2A protocol natively?

Yes, the R5F10PGHCLFB#15 includes a dedicated LIN controller that fully complies with LIN 2.2A and SAE J2602 standards. It supports both master and slave modes, automatic baud rate detection, checksum generation (classic and enhanced), and error handling without firmware overhead. The R5F10PGHCLFB#15 implements LIN physical layer signaling via configurable port pins (e.g., P10/P11), eliminating need for external transceivers in many slave-node designs.

What are the power supply requirements for the R5F10PGHCLFB#15?

The R5F10PGHCLFB#15 operates from a single supply rail ranging from 1.6 V to 5.5 V, supporting direct connection to common system rails including 3.3 V and 5 V logic. It features separate analog (EVDD0/EVSS0) and digital (VDD/VSS) power domains to minimize noise coupling. An external 1.0 μF capacitor must be connected to the REGC pin to stabilize the internal regulator for analog circuitry, ensuring ADC accuracy and RTC stability across voltage and temperature ranges.

How much flash memory and RAM does the R5F10PGHCLFB#15 include?

The R5F10PGHCLFB#15 integrates 96 KB of on-chip flash memory and 8 KB of RAM. The flash supports 100,000 write/erase cycles and 20-year data retention at 85°C, making it suitable for field-upgradable firmware in industrial equipment. The 8 KB RAM includes dedicated areas for stack, heap, and peripheral buffers - sufficient for concurrent LIN messaging, ADC data streaming, and real-time control loops without external memory.

Is the R5F10PGHCLFB#15 pin-compatible with other RL78/F14 48-pin variants?

Yes, the R5F10PGHCLFB#15 shares identical pinout and package (48-pin LQFP) with all RL78/F14 devices in the PGn series (e.g., R5F10PGGCLFB#15, R5F10PGJCLFB#15). Pin compatibility extends across flash/RAM configurations and peripheral enablement - allowing hardware reuse across firmware variants. However, differences in on-chip peripheral availability (e.g., number of timers or ADC channels) must be verified per specific variant datasheet before substitution.
