FAQ

What is the maximum operating frequency of the R5F363AKDFA#U0 and under what voltage conditions?

The R5F363AKDFA#U0 achieves a maximum operating frequency of 20 MHz when VCC1 is supplied at 2.7 V to 5.5 V. At lower voltages - 2.1 V to below 2.7 V - it operates up to 10 MHz, and at 1.8 V it runs at 5 MHz. These graded frequency/voltage relationships ensure stable operation across diverse power domains while maintaining timing integrity for peripherals like UART and timers.

Does the R5F363AKDFA#U0 support external memory expansion, and what bus configurations are available?

Yes, the R5F363AKDFA#U0 supports external memory expansion with a 1 MB base address space expandable to 4 MB. It offers flexible bus formats: separate or multiplexed bus modes, selectable data bus width (8 or 16 bits), and configurable address bus size (12/16/20 bits). Four chip select outputs and programmable wait states (0–8) allow interfacing with diverse SRAM, Flash, and peripheral ICs without glue logic.

How many A/D converter channels does the R5F363AKDFA#U0 provide, and what is their resolution and conversion time?

The R5F363AKDFA#U0 integrates a 10-bit resolution A/D converter with 26 input channels, including dedicated AN0_x and AN2_x groups plus auxiliary inputs (ANEX0/ANEX1). Conversion time is fixed at 2.15 µs per sample, enabled by an internal sample-and-hold circuit that ensures accuracy during dynamic signal acquisition in motor control or sensor monitoring applications.

What CEC functionality is implemented in the R5F363AKDFA#U0, and how is it physically interfaced?

The R5F363AKDFA#U0 implements full HDMI CEC protocol support including transmit/receive, arbitration lost detection, and automatic ACK generation - all operating at the standardized 32 kHz clock rate. The CEC signal is routed through pin P8_5, which shares NMI and serial download functions; external 1:1 impedance-matched termination (typically 330 Ω pull-up to 3.3 V) is required per HDMI specification.

Is on-chip debug supported for the R5F363AKDFA#U0, and what capabilities does it include?

Yes, the R5F363AKDFA#U0 includes full on-chip debug capability compliant with Renesas' standard debug interface. It supports real-time program execution control, four address match interrupts for breakpoint setting, memory/register inspection, and in-system flash rewriting - all accessible via JTAG without requiring external debug probes or bootloaders, streamlining development and field firmware updates.
