FAQ

What is the maximum operating frequency and DMIPS performance of the R5F524UEADFB#30?

The R5F524UEADFB#30 operates at a maximum frequency of 80 MHz and delivers 153.6 DMIPS (Dhrystone MIPS) performance. This is achieved using the RXv2 CPU core with 5-stage pipeline, variable-length instructions, and on-chip 2 KB ROM cache. The R5F524UEADFB#30 maintains this performance across its full operating voltage range (2.7–5.5 V) and temperature range (−40 to +85°C).

Does the R5F524UEADFB#30 support simultaneous sampling across multiple ADC channels?

Yes, the R5F524UEADFB#30 supports true simultaneous sampling on three channels within S12ADF unit 1, enabled by its integrated 3-channel sample-and-hold circuit. This capability is critical for motor current sensing in field-oriented control applications. The R5F524UEADFB#30 also allows independent sampling time configuration per channel and group scan priority control across three levels.

What safety features does the R5F524UEADFB#30 include for IEC60730 compliance?

The R5F524UEADFB#30 includes hardware-assisted IEC60730 compliance features: self-diagnostic ADC, clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT) with dedicated oscillator, RAM test assistance via DOC, and analog input disconnection detection. These features are documented in the R01DS0278EJ0100 datasheet and enable Class B certification without external components. The R5F524UEADFB#30 implements them natively in silicon.

Can the R5F524UEADFB#30 generate three-phase complementary PWM waveforms?

Yes, the R5F524UEADFB#30's MTU3 module supports two independent three-phase complementary PWM outputs with automatic dead-time insertion, adjustable duty cycle (0–100%), and reset-synchronized PWM mode. Each output pair can drive high-side/low-side gate drivers in inverter bridges. The R5F524UEADFB#30 also supports phase counting and dead-time compensation counter functions for precise timing control.

What is the package type and pin count of the R5F524UEADFB#30?

The R5F524UEADFB#30 uses a 144-pin Low-profile Quad Flat Package (LFQFP) with part code PLQP0144KA-B, measuring 20 × 20 mm with 0.5 mm pitch. It is lead-free (Sn-only surface finish) and RoHS compliant. This package provides 110 general-purpose I/O pins, 2 × 5-V tolerant inputs, and 90 open-drain outputs - validated in Table 1.2 of the R01DS0278EJ0100 datasheet for the R5F524UEADFB#30.
