FAQ

What is the maximum operating frequency and voltage range for the R5F364AKDFB#10?

The R5F364AKDFB#10 operates at a maximum frequency of 25 MHz with a supply voltage range of 2.7 V to 5.5 V across both VCC1 (core/analog) and VCC2 (external bus) rails. Its minimum instruction execution time is 40.0 ns under these conditions, and it supports single-chip, memory expansion, and microprocessor operating modes. The dual-voltage architecture allows independent rail configuration for mixed-signal interfacing.

Does the R5F364AKDFB#10 support hardware-based three-phase motor control?

Yes, the R5F364AKDFB#10 integrates dedicated three-phase motor control circuitry using Timer A1, A2, A4, and Timer B2, including an on-chip dead-time timer. This enables generation of complementary PWM signals with programmable dead-time insertion directly from hardware, eliminating the need for external logic or software compensation in inverter gate drive applications.

What analog capabilities does the R5F364AKDFB#10 provide?

The R5F364AKDFB#10 includes a 10-bit A/D converter with 26 input channels (AN0–AN7, AN0_0–AN0_7, AN2_0–AN2_7, ANEX0/ANEX1), sample-and-hold function, and 1.72 µs conversion time. It also features two 8-bit D/A converters (DA0/DA1) and reference voltage input (VREF) for precision analog measurement and control loop implementation.

How is the external memory interface configured on the R5F364AKDFB#10?

The R5F364AKDFB#10 supports external memory expansion with a 1 MB base address space (expandable to 4 MB), selectable 8- or 16-bit data bus width, 12/16/20-bit address bus, and 0–3 programmable wait states. Bus format (separate or multiplexed) and chip-select outputs (CS0–CS3) are configurable via control registers, enabling direct connection to SRAM, Flash, or peripheral ASICs.

Is CEC functionality implemented in hardware or firmware on the R5F364AKDFB#10?

CEC functionality on the R5F364AKDFB#10 is implemented in dedicated hardware: the CEC transceiver operates at 32 kHz, handles arbitration loss detection, and provides automatic ACK output. This offloads timing-critical protocol handling from the CPU, ensuring HDMI compliance without consuming significant firmware resources or requiring precise software timing loops.
