For engineers reviewing the R5F526T9AGFP#50 datasheet, R5F526T9AGFP#50 pinout, R5F526T9AGFP#50 application, or R5F526T9AGFP#50 equivalent, key selection criteria include its 120 MHz GPTWa timer with 3-phase/5-phase complementary PWM, dual-bank flash for safe firmware updates, Trusted Secure IP Lite encryption, and hardware-accelerated trigonometric functions (TFUv2) for real-time motor vector control.

Technical Context

The R5F526T9AGFP#50 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and collective register bank save for fast context switching. Its clock system integrates PLL, HOCO (16/18/20 MHz), LOCO (240 kHz), and IWDT-dedicated 120 kHz oscillator - enabling independent peripheral clock domains (PCLKA up to 120 MHz, PCLKB/C/D at derived frequencies).

Motor control is enabled by tightly coupled peripherals: MTU3d (9-channel 16-bit timer) and GPTWa (8-channel 32-bit timer) both synchronized to PCLKC for precise PWM generation; HRPWM (4 channels) overlays sub-nanosecond timing control onto GPTW outputs; and S12ADH (12-bit ADC with 3 sample-and-hold units) supports simultaneous sampling of current/voltage feedback signals.

FAQ

What is the maximum operating frequency and CPU architecture of the R5F526T9AGFP#50?

The R5F526T9AGFP#50 features a 32-bit RXv3 CPU core with a maximum operating frequency of 120 MHz and achieves 709 CoreMark performance. It supports single-cycle instruction execution, IEEE 754-compliant single-precision floating-point unit (FPU), and collective register bank save for rapid context switching - all essential for deterministic motor control loop execution in the R5F526T9AGFP#50.

Does the R5F526T9AGFP#50 support IEC60730 safety compliance?

Yes, the R5F526T9AGFP#50 includes multiple hardware features for IEC60730 Class B compliance: oscillation-stoppage detection, self-diagnostic A/D converter disconnection detection, clock frequency accuracy measurement circuit, independent watchdog timer (IWDT), RAM test-assisting function using DOC, CRC calculator (CRCA), and register write protection. These capabilities are documented in the R5F526T9AGFP#50 datasheet and enable certified safety monitoring without external components.

What PWM resolution and channel count does the R5F526T9AGFP#50 provide for motor control?

The R5F526T9AGFP#50 delivers three-tiered PWM capability: GPTWa (8×32-bit channels), MTU3d (9×16-bit channels), and HRPWM (4 channels) overlaying 260 ps minimum timing resolution onto GPTW outputs. This enables precise dead-time insertion, phase-aligned complementary waveforms, and 3-phase/5-phase inverter control - all critical for low-noise, high-efficiency operation in the R5F526T9AGFP#50.

How many ADC channels and sample-and-hold units does the R5F526T9AGFP#50 integrate?

The R5F526T9AGFP#50 integrates a 12-bit S12ADH ADC with 22 total input channels distributed across three units: Unit 0 (4 channels, 3 sample-and-hold circuits), Unit 1 (4 channels, 3 sample-and-hold circuits), and Unit 2 (14 channels). This architecture supports true simultaneous sampling of up to six analog signals - such as motor phase currents and DC-link voltage - which is a defining feature of the R5F526T9AGFP#50 for real-time motor control.

What communication interfaces are available on the R5F526T9AGFP#50?

The R5F526T9AGFP#50 provides CAN FD (ISO11898-1:2015 compliant, 1 channel), RIICa (I²C/SMBus up to 400 kbps), RI3C (I3C SDR mode), RSPId (SPI up to 30 Mbps), RSPIA (TI SSP-compatible SPI), 4×SCI, and 3×RSCI (with Manchester encoding and HBS support). This comprehensive interface set enables robust connectivity in complex motor drive systems using the R5F526T9AGFP#50.
