FAQ

What is the maximum operating frequency and corresponding instruction timing for R5F364AKDFA#U0?

The R5F364AKDFA#U0 operates at up to 25 MHz with a minimum instruction execution time of 40.0 ns under VCC1 = VCC2 = 2.7–5.5 V conditions. This timing is guaranteed across its full -40°C to +85°C industrial temperature range and applies to all 91 basic instructions of the M16C/60 core, including multiply and accumulate operations enabled by its integrated 16×16-bit hardware multiplier.

Does R5F364AKDFA#U0 support HDMI CEC functionality, and how is it implemented?

Yes, R5F364AKDFA#U0 includes native CEC (Consumer Electronics Control) transceiver functionality compliant with HDMI CEC standards. It implements CEC transmit/receive, arbitration loss detection, and automatic ACK generation at 32 kHz, using dedicated hardware on pin P8_5 (NMI/SD/CEC) configured as an N-channel open-drain I/O requiring external pull-up. The CEC peripheral operates independently of the CPU core during low-power modes.

What are the memory configuration details for R5F364AKDFA#U0, including endurance and security features?

R5F364AKDFA#U0 contains 384 KB program ROM, 16 KB RAM, and 31 KB data flash. Program ROM supports 1,000 write/erase cycles; data flash supports 10,000 cycles. Security features include ROM code protection to prevent unauthorized readout and ID code check for secure boot authentication - both enforced through dedicated on-chip registers accessible only during debug initialization sequences.

How does the three-phase motor control capability of R5F364AKDFA#U0 differ from generic timer peripherals?

R5F364AKDFA#U0 integrates dedicated three-phase inverter control logic using Timer A1, A2, A4 and Timer B2, with hardware-generated dead-time insertion between complementary PWM outputs. Unlike general-purpose timers, this block synchronizes six PWM channels, enforces minimum off-time between high-side and low-side drive signals, and supports fault shutdown via SD (forced cutoff) input - eliminating need for external dead-time ICs or software-based timing compensation.

What debug and programming interfaces are supported by R5F364AKDFA#U0?

R5F364AKDFA#U0 supports on-chip debug (ICE) via dedicated debug pins and includes on-board flash rewrite capability. It provides four address match interrupts for precise breakpointing, real-time register visibility, and non-intrusive code execution tracing. Programming is performed through the on-chip debug interface without requiring external programmers - enabling field firmware updates and production-line programming directly over the debug port.
