FAQ

What is the maximum operating frequency and CPU architecture of the R5F52305ADFL#30?

The R5F52305ADFL#30 features a 32-bit RXv2 CPU core with a maximum operating frequency of 54 MHz, delivering 88.56 DMIPS. It includes an IEEE 754-compliant single-precision FPU, 32×32→64-bit multiplier, and 32-bit divider with 2-cycle minimum latency. This architecture enables deterministic real-time execution for motor control, sensor fusion, and industrial communication stacks in the R5F52305ADFL#30.

Does the R5F52305ADFL#30 include a real-time clock (RTC) and what are its capabilities?

No, the R5F52305ADFL#30 does not include an RTC module. According to Table 1.2 in the datasheet, RTC is unavailable in the 48-pin RX230 Group variants-including R5F52305ADFL#30-though it is present in selected 100-pin and 64-pin RX231 Group parts. The R5F52305ADFL#30 retains the low-power timer (LPT) for timekeeping during software standby, but lacks calendar-mode counting, alarm interrupts, or time-capture functionality found in RTC-equipped variants.

What communication interfaces are supported by the R5F52305ADFL#30?

The R5F52305ADFL#30 supports USB 2.0 full-speed host/function/OTG (12 Mbps), CAN (1 channel, ISO11898-1 compliant, up to 1 Mbps), four SCI channels (asynchronous/clock-synchronous), one I²C bus interface (400 kbps), one RSPI channel (16 Mbps), and one serial sound interface. It does not include SD host interface or IrDA, which are omitted in the 48-pin RX230 Group configuration per Table 1.2 of the datasheet.

What is the package type and pin count of the R5F52305ADFL#30?

The R5F52305ADFL#30 uses the PLQP0048KB-B package: a 48-pin Low-profile Quad Flat Package with 7 mm × 7 mm body size, 0.5 mm lead pitch, and exposed thermal pad. This package is RoHS-compliant and rated for −40 to +85°C operation. Pin compatibility is maintained across all RX230 Group 48-pin variants, including R5F52305ADFL#30, R5F52306ADFL#30, and R5F52315ADFL#30.

Does the R5F52305ADFL#30 support hardware encryption and what algorithms are implemented?

Yes, the R5F52305ADFL#30 integrates TSIP-Lite-a trusted secure IP module supporting AES-128 and AES-256 encryption in ECB, CBC, GCM, CMAC, XTS, CTR, and GCTR modes. It includes a true random number generator, key protection circuitry preventing unauthorized access to the encryption engine, and secure key management. These features are confirmed in the "Encryption Functions" section of the R01DS0261EJ0120 datasheet and apply directly to the R5F52305ADFL#30.
