For engineers reviewing the R5F526T9AGFM#30 datasheet, R5F526T9AGFM#30 pinout, R5F526T9AGFM#30 application, or R5F526T9AGFM#30 equivalent, key selection criteria include its 100-pin LFQFP package, 3-phase/5-phase complementary PWM capability, simultaneous sampling across three 12-bit ADC units, and dedicated HRPWM circuitry for precision motor timing control.

Technical Context

The R5F526T9AGFM#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and 16-register bank save for fast context switching in real-time motor control loops. Its clock system integrates PLL with external 8–24 MHz crystal support, internal HOCO (16/18/20 MHz), and dedicated 120 kHz IWDT oscillator.

Peripheral coordination is enabled by the Event Link Controller (ELC), which interconnects 183 internal event signals-allowing MTU3d, GPTWa, and S12ADH to operate synchronously without CPU intervention during PWM-triggered ADC sampling or dead-time compensated inverter gate driving.

FAQ

What is the maximum operating frequency and CPU architecture of the R5F526T9AGFM#30?

The R5F526T9AGFM#30 operates at up to 120 MHz using the 32-bit RXv3 CPU core, delivering 709 CoreMark performance. It supports single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and collective register bank save for rapid context switching - all critical for deterministic motor control loops. The R5F526T9AGFM#30 achieves this performance with no wait states on its 512 KB flash and 64 KB SRAM.

Does the R5F526T9AGFM#30 support IEC60730 Class B compliance out of the box?

Yes, the R5F526T9AGFM#30 includes hardware features required for IEC60730 Class B: oscillation-stop detection, RAM test assistance via DOC, CRC calculator (CRCA), independent watchdog timer (IWDTa) with window function, and register write protection. These are complemented by software libraries and documentation from Renesas to accelerate certification - the R5F526T9AGFM#30 itself provides the foundational safety mechanisms.

What ADC configuration does the R5F526T9AGFM#30 support, and how many channels are available?

The R5F526T9AGFM#30 includes three 12-bit S12ADH units: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels), totaling 22 analog inputs. All units support simultaneous sampling, 0.9 µs conversion time at 60 MHz ADCLK, and channel-specific sampling time control - essential for synchronized current/voltage measurement in motor control. The R5F526T9AGFM#30 also integrates programmable gain amplifiers on Units 0 and 1.

Can the R5F526T9AGFM#30 generate true 3-phase complementary PWM waveforms with hardware dead-time insertion?

Yes, the R5F526T9AGFM#30 supports true 3-phase complementary PWM via its MTU3d and GPTWa timers, with automatic hardware dead-time insertion and non-overlapping waveform generation. The MTU3d provides 3-phase PWM with configurable dead times, while GPTWa adds 10-channel single-phase, 3-channel 3-phase, and 2-channel 5-phase modes - all synchronized and controllable through the R5F526T9AGFM#30's ELC for glitch-free transitions.

What package type and pin count does the R5F526T9AGFM#30 use, and is it RoHS compliant?

The R5F526T9AGFM#30 uses a 100-pin LFQFP package (PLQP0100KB-B), measuring 14 × 14 mm with 0.5 mm pitch, and is fully RoHS compliant and lead-free. It provides 82 general-purpose I/O pins (including 2× 5-V tolerant), dedicated analog inputs, CAN FD transceiver pins, and JTAG/FINE debug interfaces - all verified in the official Renesas datasheet R01DS0407EJ0120 Rev.1.20. The R5F526T9AGFM#30 meets JEDEC standards for moisture sensitivity level (MSL3).
