FAQ
What is the maximum operating frequency and core type of the R5F51405ADFK#10?
The R5F51405ADFK#10 features a 32-bit RXv2 CPU core with a maximum operating frequency of 48 MHz, achieving 204 CoreMark performance. It includes an IEEE-754-compliant single-precision FPU, 32-bit multiplier, and on-chip divider. This enables deterministic real-time execution for motor control and sensor processing tasks without external math acceleration.
Does the R5F51405ADFK#10 include hardware encryption capabilities?
Yes, the R5F51405ADFK#10 integrates the AESA hardware accelerator supporting 128-bit and 256-bit AES encryption in ECB, CBC, and CTR modes, along with the RNGA true random number generator. These modules are present in the "A" variant (no encryption) - however, per Renesas documentation, R5F51405ADFK#10 does not include the AESA or RNGA blocks; those are only available in "B" suffix variants like R5F51405BDFK#30.
What package type and pin count does the R5F51405ADFK#10 use?
The R5F51405ADFK#10 uses the PLQP0064GA-A package: a 64-pin LQFP with 14 × 14 mm body size and 0.8 mm pin pitch. This package is RoHS-compliant and optimized for industrial reflow profiles. Pin functions include 15 A/D inputs, dual D/A outputs, CAN, multiple SCI/RSPI/I²C interfaces, and MTU2a PWM outputs.
What are the key low-power features of the R5F51405ADFK#10?
The R5F51405ADFK#10 supports four low-power modes, including software standby with typical current consumption of 0.25 µA at 25°C. Recovery time from software standby is 6.2 µs (with HOCO 32 MHz clock source). The low-power timer (LPTa) continues operating during standby, enabling periodic wake-up events without full system restart - critical for battery-powered sensor nodes.
Is the R5F51405ADFK#10 compliant with IEC60730 safety standards?
Yes, the R5F51405ADFK#10 includes dedicated hardware features for IEC60730 Class B compliance, including self-diagnostic support for the A/D converter, clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT), and RAM test assistance using the DOC. These reduce external component count and simplify certification for household and industrial appliances.
