FAQ

What is the maximum operating frequency and core type of the R5F51403AGNE#30?

The R5F51403AGNE#30 features a 32-bit RXv2 CPU core with a maximum operating frequency of 48 MHz. It achieves 204 CoreMark at this speed and includes an IEEE-754-compliant single-precision floating-point unit. The core uses a 5-stage pipeline and variable-length instruction encoding to optimize code density and execution efficiency. This performance level supports real-time control loops and sensor fusion algorithms in resource-constrained industrial applications.

Which package and temperature grade does the R5F51403AGNE#30 use?

The R5F51403AGNE#30 uses the PWQN0048KC-A package: a 48-pin HWQFN with 7 mm × 7 mm body, 0.5 mm pitch, and exposed thermal pad. It is rated for –40 to +105°C operation (G-grade), making it suitable for under-hood automotive modules, industrial drives, and factory-floor controllers where ambient temperatures exceed standard commercial limits.

Does the R5F51403AGNE#30 include hardware encryption or a real-time clock?

The R5F51403AGNE#30 does not include AES hardware acceleration or RNG - the 'A' in the part number denotes absence of encryption modules. However, it does integrate a full-featured RTC (RTCB) with calendar count mode, alarm interrupts, and 32.768 kHz sub-clock support. This allows time-stamped data logging and scheduled wake-up events without external components.

How many ADC channels and what resolution does the R5F51403AGNE#30 support?

The R5F51403AGNE#30 integrates a 12-bit successive-approximation A/D converter (S12ADE) with 11 external input channels and one internal channel (temperature sensor). Minimum conversion time is 0.67 µs at 48 MHz ADCLK. Sampling time is configurable per channel, and features include conversion result comparison, self-diagnostic mode, and double-trigger capability for motor control synchronization.

What communication interfaces are available on the R5F51403AGNE#30?

The R5F51403AGNE#30 provides one CAN 2.0B channel (1 Mbps), five SCI channels (including LIN-capable SCIh), one I²C interface (400 kbps, SMBus-compatible), and one RSPI channel (16 Mbps). It lacks the sixth SCI and second I²C found in larger RX140 variants, but retains full ELC-triggered peripheral coordination for deterministic communication sequencing in real-time systems.
