FAQ

What is the maximum operating frequency and DMIPS rating of the R5F524UCADFB#30?

The R5F524UCADFB#30 operates at a maximum frequency of 80 MHz and delivers 153.6 DMIPS performance. This is achieved through its 32-bit RXv2 CPU core with 5-stage pipeline, variable-length instruction set, and on-chip 32-bit multiplier/divider. The R5F524UCADFB#30 maintains this performance across its full operating voltage range (2.7–5.5 V) and temperature range (−40 to +85°C), with no wait states for SRAM access at 80 MHz.

Does the R5F524UCADFB#30 support IEC60730 functional safety compliance?

Yes, the R5F524UCADFB#30 includes multiple hardware-assisted features for IEC60730 Class B compliance, including RAM test assistance via the Data Operation Circuit (DOC), ADC self-diagnostic and analog input disconnection detection, independent watchdog timer (IWDT) with dedicated 15-kHz oscillator, and Clock Frequency Accuracy Measurement Circuit (CAC). These capabilities are documented in the R01DS0278EJ0100 datasheet and enable certified safety routines without external components. The R5F524UCADFB#30 is widely used in certified industrial control equipment.

What ADC configuration does the R5F524UCADFB#30 provide, and how many channels support simultaneous sampling?

The R5F524UCADFB#30 integrates the S12ADF 12-bit ADC with three independent units: Unit 0 (5 channels), Unit 1 (5 channels), and Unit 2 (12 channels). Unit 1 includes a 3-channel simultaneous sample-and-hold circuit, enabling true concurrent acquisition - critical for motor phase current measurement. Each channel supports programmable sampling time, group scan priority, and PGA gain settings (2.0× to 13.333×). The R5F524UCADFB#30 achieves minimum conversion time of 1.0 µs per channel at 40-MHz ADCLK.

Which PWM peripherals in the R5F524UCADFB#30 support three-phase complementary output with dead-time control?

The R5F524UCADFB#30 supports three-phase complementary PWM primarily through its MTU3 (Multi-function Timer Pulse Unit 3), which provides two independent 3-phase output channels with automatic dead-time insertion, non-overlapping waveform generation, and adjustable duty cycle (0–100%). GPT (General PWM Timer) adds four 16-bit channels capable of single-phase complementary or cascaded 3-phase output. Both peripherals synchronize with PCLKA (80 MHz), ensuring precise edge placement. The R5F524UCADFB#30 uses these for inverter gate driving in motor control applications.

What is the package type and pin count of the R5F524UCADFB#30, and is it RoHS compliant?

The R5F524UCADFB#30 uses a 144-pin Low-Profile Quad Flat Package (LFQFP) with part code PLQP0144KA-B: 20 × 20 mm body, 0.5 mm pitch, lead-free (Sn-only surface finish), and fully RoHS compliant. It provides 110 general-purpose I/O pins, including 90 open-drain outputs and 2×5-V-tolerant inputs. The package is optimized for industrial PCB assembly and thermal dissipation in enclosed enclosures. All R5F524UCADFB#30 units supplied by Aetrix Electronics meet JEDEC J-STD-020 moisture sensitivity level 3 and IPC/JEDEC J-STD-033 handling requirements.
