FAQ

What is the maximum operating frequency and core architecture of the R5F51405AGFN#30?

The R5F51405AGFN#30 operates at a maximum frequency of 48 MHz using the 32-bit RXv2 CPU core-a CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and ultra-compact code density. It achieves 204 CoreMark at full speed and includes on-chip FPU, 32-bit multiplier, and 2-cycle divider for deterministic real-time computation. This performance is fully supported in the R5F51405AGFN#30's 128 KB flash and 32 KB SRAM configuration.

Does the R5F51405AGFN#30 include hardware encryption capabilities?

No, the R5F51405AGFN#30 does not include hardware encryption modules. Its part number suffix "A" indicates absence of AESA and RNGA accelerators-confirmed in Table 1.3 of R01DS0379EJ0120 Rev.1.20. For AES-128/256 or true random number generation, select part numbers with suffix "B" (e.g., R5F51405BGFN#30). The R5F51405AGFN#30 retains all other peripherals including CAN, CTSU2SL, and IEC60730 safety assist functions.

What package type and pin count does the R5F51405AGFN#30 use?

The R5F51405AGFN#30 uses the PLQP0080KB-B package: an 80-pin Low-Profile Quad Flat Package with 12 mm × 12 mm body size, 0.5 mm lead pitch, and exposed thermal pad. This matches the "FN" suffix in its part number per Figure 1.1 of the datasheet. It is RoHS-compliant and rated for –40°C to +105°C operation-distinct from 64-pin or 48-pin variants in the RX140 family.

How many A/D converter channels does the R5F51405AGFN#30 support, and what is its conversion speed?

The R5F51405AGFN#30 integrates the S12ADE 12-bit A/D converter with 17 external input channels and 1 internal channel (temperature sensor), totaling 18 channels. At maximum ADCLK of 48 MHz, it achieves a minimum conversion time of 0.67 µs per channel. Sampling time is programmable per channel, and features include conversion result comparison, double-trigger mode for motor control, and analog input disconnection detection-all documented in Section 35 of the RX140 User's Manual.

Is the R5F51405AGFN#30 CAN 2.0B compliant, and what data rate does it support?

Yes, the R5F51405AGFN#30 includes the RSCAN CAN module compliant with ISO11898-1 (CAN 2.0B), supporting both standard and extended frames. It operates at data rates up to 1 Mbps, with 16 configurable mailboxes and hardware filtering. This capability is retained across all RX140 packages-including the 80-pin PLQP0080KB-B used by the R5F51405AGFN#30-as confirmed in Table 1.2 and Section 37 of the hardware manual.
