For engineers reviewing the R5F51405ADFM#30 datasheet, R5F51405ADFM#30 pinout, R5F51405ADFM#30 application, or R5F51405ADFM#30 equivalent, this device supports IEC60730-compliant safety functions, low-power software standby mode (0.25 µA typ.), and capacitive touch sensing (up to 32 keys) - critical for embedded motor control, sensor interface, and HMI designs requiring deterministic real-time response.

Technical Context

The R5F51405ADFM#30 implements the RXv2 CPU core with IEEE-754-compliant 32-bit FPU, 204 CoreMark score at 48 MHz, and Harvard architecture with 5-stage pipeline. It integrates a 16-channel MTU2 timer unit supporting complementary PWM and phase counting, plus ELC for event-driven peripheral coordination without CPU intervention.

Its clock system includes HOCO (48 MHz ±1%), sub-clock oscillator (32.768 kHz), PLL, and CAC for clock accuracy measurement. The device supports dual-voltage operation (1.8–5.5 V), four low-power modes, and hardware-accelerated AES/RNG only in B-variant parts - not present in R5F51405ADFM#30 per Table 1.3.

FAQ

What is the maximum operating frequency and core type of the R5F51405ADFM#30?

The R5F51405ADFM#30 features a 32-bit RXv2 CPU core with a maximum operating frequency of 48 MHz. It achieves 204 CoreMark performance at that speed and includes an IEEE-754-compliant 32-bit floating-point unit. This core enables deterministic real-time execution for industrial control loops and sensor fusion algorithms within the R5F51405ADFM#30.

Does the R5F51405ADFM#30 include hardware encryption acceleration?

No, the R5F51405ADFM#30 does not include hardware encryption acceleration. Per Table 1.3 in the datasheet, only parts with "B" in the fifth character (e.g., R5F51405BDFM#30) integrate the AESA and RNGA modules. The "A" in R5F51405ADFM#30 explicitly denotes absence of encryption hardware - a key differentiator for secure firmware update or data confidentiality requirements.

What package type and pin count does the R5F51405ADFM#30 use?

The R5F51405ADFM#30 uses the PLQP0064KB-C package: a 64-pin Low-Profile Quad Flat Package with 10 × 10 mm body size and 0.5 mm pin pitch. This LFQFP variant includes an exposed thermal pad and is optimized for compact industrial PCB layouts requiring fine-pitch assembly and efficient heat dissipation.

How many analog-to-digital converter channels does the R5F51405ADFM#30 support?

The R5F51405ADFM#30 integrates the S12ADE 12-bit A/D converter with 15 external input channels and one internal channel (temperature sensor), totaling 16 usable analog inputs. Table 1.2 confirms 15 external channels for 64-pin variants like R5F51405ADFM#30, enabling simultaneous sampling across multiple sensors in motor control or environmental monitoring applications.

Is the real-time clock (RTC) available in the R5F51405ADFM#30?

Yes, the R5F51405ADFM#30 includes the RTCB (Realtime Clock) module. As confirmed in Table 1.2, RTC is supported in all 64-pin and 80-pin RX140 products with 128 KB or larger ROM - which includes R5F51405ADFM#30 (128 KB flash). It supports calendar mode with leap-year correction and operates during software standby using the 32.768 kHz sub-clock oscillator.
