Overview

R5F526T9BGND#50 from Renesas is a 32-bit RXv3 microcontroller designed for high-performance motor control and industrial inverter applications. It operates at up to 120 MHz, integrates 512 KB code flash, 64 KB SRAM, 16 KB data flash, dual-bank flash architecture, and supports CAN FD, 3-phase/5-phase complementary PWM, and 260-ps resolution HRPWM. It targets real-time closed-loop motor drive systems requiring IEC60730 compliance.

For engineers reviewing the R5F526T9BGND#50 datasheet, R5F526T9BGND#50 pinout, R5F526T9BGND#50 application, or R5F526T9BGND#50 equivalent, key selection criteria include its 120-MHz GPTWa timer with 10-channel single-phase complementary PWM, integrated 12-bit S12ADH ADC with simultaneous sampling across three units, on-chip Trusted Secure IP Lite encryption, and support for 5-V tolerant I/O in PLQP0100KB-B 100-pin QFP package.

Technical Context

The R5F526T9BGND#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 in motor control interrupt service routines. Its clock system combines an 8–24 MHz external crystal with PLL multiplication to achieve 120 MHz ICLK, while PCLKA (120 MHz), PCLKC (120 MHz), and PCLKD (60 MHz) independently drive peripherals including GPTWa, HRPWM, and S12ADH.

It features hardware-accelerated safety functions including oscillation-stop detection, RAM test assistance via DOC, CRC calculation (CRCA), and register write protection - all aligned with IEC60730 Class B requirements. The ELC enables event-triggered peripheral coordination without CPU intervention, critical for deterministic timing in inverter gate-drive sequencing and ADC sampling synchronization.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526T9BGND#50?

The R5F526T9BGND#50 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark in benchmark testing. This performance level enables fast execution of field-oriented control algorithms and real-time signal processing tasks essential for high-speed motor control applications. The R5F526T9BGND#50 uses the RXv3 CPU core with single-cycle instruction execution and integrated FPU to sustain this throughput.

Does the R5F526T9BGND#50 support IEC60730 Class B compliance out of the box?

Yes, the R5F526T9BGND#50 includes multiple hardware features required for IEC60730 Class B compliance: oscillation-stop detection, RAM test assistance via DOC, CRC calculator (CRCA), independent watchdog timer (IWDT) with window function, register write protection, and self-diagnostic ADC/comparator functions. These capabilities are documented in the R01DS0407EJ0120 datasheet and reduce the need for external safety monitoring circuits when implementing R5F526T9BGND#50 in certified motor control systems.

What ADC configuration does the R5F526T9BGND#50 provide, and how many channels support simultaneous sampling?

The R5F526T9BGND#50 integrates three 12-bit S12ADH ADC units: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels), totaling 22 input channels. Units 0 and 1 each include three dedicated sample-and-hold circuits, enabling true simultaneous sampling across up to six channels. This configuration supports synchronized current sensing in 3-shunt motor control topologies. The R5F526T9BGND#50 achieves 0.9 µs minimum conversion time per channel when ADCLK runs at 60 MHz.

What PWM resolution and channel count does the R5F526T9BGND#50 offer for motor control?

The R5F526T9BGND#50 provides 8-channel 32-bit GPTWa timers plus 4-channel HRPWM with a minimum timing resolution of 260 ps at 120 MHz operation. It supports 10 output channels in single-phase complementary PWM mode, 3 channels in 3-phase complementary mode, and 2 channels in 5-phase complementary mode. This enables direct control of multi-leg inverter topologies with precise dead-time insertion and phase alignment - a core capability of the R5F526T9BGND#50 for high-efficiency motor drives.

Which package type and pin count does the R5F526T9BGND#50 use?

The R5F526T9BGND#50 is packaged in PLQP0100KB-B: a 100-pin low-profile quad flat package measuring 14 × 14 mm with 0.5 mm pitch and an exposed thermal pad.
