FAQ

What is the operating voltage range for the R5F364AMDFB#10?

The R5F364AMDFB#10 operates from 2.7 V to 5.5 V on both VCC1 (core/peripherals) and VCC2 (external bus) supplies. This dual-rail design allows independent voltage scaling - for example, 3.3 V core logic with 5 V external memory or I/O - while maintaining full functionality across the specified range. The R5F364AMDFB#10 includes an on-chip voltage detector with three configurable detection levels for power-on reset and brown-out protection.

Does the R5F364AMDFB#10 support hardware-based HDMI-CEC communication?

Yes, the R5F364AMDFB#10 integrates a dedicated CEC transceiver function on pin P8_5 (NMI/SD/CEC), supporting full HDMI-CEC protocol operations including transmit/receive, arbitration loss detection, and automatic ACK output at 32 kHz. This hardware acceleration offloads bit-level timing from firmware and ensures compliance with HDMI CEC specification v1.4 without external components. The R5F364AMDFB#10 implements this feature natively - no software emulation or external PHY is required.

How many analog input channels does the R5F364AMDFB#10 support, and what is their resolution?

The R5F364AMDFB#10 supports 26 analog input channels with 10-bit resolution, organized as AN0–AN7 (8 channels), AN0_0–AN0_7 (8 channels), AN2_0–AN2_7 (8 channels), plus ANEX0 and ANEX1 (2 extended inputs). All channels include sample-and-hold circuitry, and conversion time is fixed at 1.72 µs. This capability enables simultaneous acquisition of multiple sensors - such as temperature, current, and position - in motor control or appliance monitoring applications using the R5F364AMDFB#10.

What package type and pin count does the R5F364AMDFB#10 use?

The R5F364AMDFB#10 uses a 100-pin LQFP package designated PLQP0100KB-A (previously coded 100P6Q-A), measuring 14 mm × 14 mm with 0.5 mm lead pitch. This RoHS-compliant surface-mount package provides 85 CMOS I/O ports, three N-channel open-drain outputs, and dedicated pins for external bus expansion, motor control outputs (U/V/W), and CEC signaling. The R5F364AMDFB#10 shares mechanical and thermal characteristics with other members of the M16C/64A Group in the same LQFP variant.

Can the R5F364AMDFB#10 execute code from external memory, and what bus configurations are supported?

Yes, the R5F364AMDFB#10 supports external memory expansion with a 1 MB base address space extendable to 4 MB using the memory area expansion function. It offers flexible bus configuration: selectable 8- or 16-bit data width, 12-/16-/20-bit address bus, separate or multiplexed bus modes, and up to 3 wait states. Four chip-select outputs (CS0–CS3) enable interfacing with multiple external devices. The R5F364AMDFB#10 manages this through dedicated control pins (ALE, RD, WRH/WRL, HOLD/HLDA) and dual power supply (VCC2) for robust external interface operation.
