FAQ

What is the maximum operating frequency and corresponding instruction execution time for the R5F364AMDFA#U0?

The R5F364AMDFA#U0 operates at a maximum frequency of 25 MHz, achieving a minimum instruction execution time of 40.0 ns under conditions of VCC1 = VCC2 = 2.7 to 5.5 V. This timing is guaranteed across its full -40°C to +85°C operating temperature range and enables precise motor commutation and real-time control loops without jitter.

Does the R5F364AMDFA#U0 support hardware-based CEC communication for HDMI systems?

Yes, the R5F364AMDFA#U0 includes a dedicated CEC transceiver with hardware arbitration loss detection and automatic ACK output, operating at 32 kHz. It complies with the HDMI CEC standard and is used in AV receivers and smart displays to enable system-wide power control and device synchronization without CPU intervention.

What are the flash memory specifications - particularly endurance and security - for the R5F364AMDFA#U0?

The R5F364AMDFA#U0 features 512 KB program ROM 1, 16 KB RAM, and 31 KB data flash. Data flash endurance is rated at 10,000 erase cycles, while program ROM endurance is 1,000 cycles. Security includes ROM code protection and ID code check to prevent unauthorized firmware extraction or cloning.

How does the dual power supply (VCC1/VCC2) architecture benefit system design with the R5F364AMDFA#U0?

The R5F364AMDFA#U0 separates VCC1 (core/peripherals) from VCC2 (external bus), allowing independent voltage scaling - e.g., 3.3 V core with 5 V external interface. This eliminates level shifters for legacy parallel buses, simplifies mixed-signal PCB routing, and improves noise isolation between analog peripherals and high-speed bus signals.

Which pins on the R5F364AMDFA#U0 support three-phase motor control functions, and what hardware acceleration do they provide?

The R5F364AMDFA#U0 uses Timer A1, A2, A4 and Timer B2 for three-phase inverter control, with dedicated U/V/W output pins (P7_6/P7_7/P8_0/P8_1/P7_2/P7_4) and on-chip dead-time insertion. This hardware eliminates external dead-time generators and ensures synchronized, glitch-free gate drive signals critical for IGBT/MOSFET safety in motor drives.
