FAQ

What is the maximum operating frequency and core type of the R5F51403ADFJ#30?

The R5F51403ADFJ#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 on-chip FPU compliant with IEEE-754 single-precision standards. The core uses CISC Harvard architecture with a 5-stage pipeline and variable-length instructions, optimized for code density and real-time determinism in the R5F51403ADFJ#30.

Which communication interfaces are supported by the R5F51403ADFJ#30?

The R5F51403ADFJ#30 supports one CAN 2.0B channel (ISO11898-1, up to 1 Mbps), three SCI channels (SCIh + two SCIk), one I²C bus interface (400 kbps, SMBus-compatible), and one RSPI channel (16 Mbps master/slave). Notably, it omits the RTC and second SCI group found in larger-package variants, aligning with its 32-pin LQFP constraint in the R5F51403ADFJ#30.

Does the R5F51403ADFJ#30 include hardware encryption capabilities?

Yes, the R5F51403ADFJ#30 includes the AESA (Advanced Encryption Standard Accelerator) module supporting AES-128 and AES-256 in ECB, CBC, and CTR modes, with throughput of 176 cycles (128-bit) and 240 cycles (256-bit). It also integrates RNGA (True Random Number Generator) for cryptographically secure key derivation - both features are active and verified in the R5F51403ADFJ#30 silicon.

What is the ADC resolution, channel count, and conversion speed of the R5F51403ADFJ#30?

The R5F51403ADFJ#30 integrates a 12-bit S12ADE A/D converter with 8 external input channels (AN0–AN7) and one internal temperature sensor channel. Minimum conversion time is 0.67 µs per channel when ADCLK runs at 48 MHz. Sampling time per channel is individually configurable, and the module supports disconnection detection and conversion result comparison - all confirmed for the R5F51403ADFJ#30 in its 32-pin configuration.

What package type and pin count does the R5F51403ADFJ#30 use?

The R5F51403ADFJ#30 uses the PLQP0032GB-A package: a 32-pin LQFP with 7 mm × 7 mm body size and 0.8 mm pin pitch. This package has no exposed thermal pad and is rated for –40°C to +85°C operation. Pin functions include dual VCC/VSS for noise isolation, dedicated ADC inputs (Pins 10–17), and SCI/I²C interfaces - all mapped specifically for the R5F51403ADFJ#30 variant.
