Renesas R5F526TFCGFP#30

Overview

R5F526TFCGFP#30 from Renesas is a 32-bit RXv3 core microcontroller optimized for motor control and industrial inverter applications, operating at up to 120 MHz with 709 CoreMark performance, 512 KB on-chip flash, 64 KB SRAM, and integrated CAN FD, high-resolution PWM (260 ps min. resolution), and dual-bank flash for safe firmware updates.

For engineers reviewing the R5F526TFCGFP#30 datasheet, R5F526TFCGFP#30 pinout, R5F526TFCGFP#30 application, or R5F526TFCGFP#30 equivalent, key selection criteria include its 3-phase/5-phase complementary PWM capability, IEC60730 safety support, 12-bit simultaneous-sampling ADC with three sample-and-hold units, Trusted Secure IP Lite encryption, and PLQP0100KB-B 100-pin QFP package with 5-V tolerant I/O.

Technical Context

The R5F526TFCGFP#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant FPU, and 16-register bank save for fast context switching-critical for real-time motor control loops. Its clock system integrates PLL, HOCO/LOCO oscillators, and independent IWDT clock (120 kHz) enabling deterministic timing across PCLKA (120 MHz), PCLKC (120 MHz for timer/HRPWM reference), and PCLKD (60 MHz for ADC).

Peripheral integration centers on deterministic timing control: GPTWa (8-channel 32-bit PWM), MTU3d (9-channel 16-bit timer), HRPWM (4-channel sub-260-ps edge control), and ELC for interrupt-free inter-module event chaining-enabling synchronized PWM, ADC trigger, and fault response without CPU intervention.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TFCGFP#30?

The R5F526TFCGFP#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark performance. This benchmark reflects its RXv3 CPU core efficiency, including single-cycle instruction execution, 32-bit multiplier/divider, and barrel shifter-enabling fast motor control loop computation. The R5F526TFCGFP#30 sustains this performance with no wait states across its 512 KB flash and 64 KB SRAM.

Does the R5F526TFCGFP#30 support simultaneous sampling across all three motor phases?

Yes, the R5F526TFCGFP#30 supports true simultaneous sampling using three independent 12-bit S12ADH ADC units (Unit 0: 4 ch, Unit 1: 4 ch, Unit 2: 14 ch), each with dedicated sample-and-hold circuits. This allows concurrent acquisition of phase currents and DC-link voltage without skew-critical for accurate field-oriented control. The R5F526TFCGFP#30 achieves 0.9 µs per channel conversion time when ADCLK runs at 60 MHz.

What PWM resolution and complementary output capabilities does the R5F526TFCGFP#30 provide?

The R5F526TFCGFP#30 provides two-tiered PWM capability: GPTWa offers 8×32-bit channels supporting 10 single-phase, 3 three-phase, and 2 five-phase complementary PWM outputs with programmable dead time; HRPWM adds 4 channels with 260 ps minimum timing resolution for fine edge control. This enables precise dead-time compensation and harmonic reduction in high-frequency inverters-key features of the R5F526TFCGFP#30's motor control architecture.

Is the R5F526TFCGFP#30 certified for IEC60730 Class B compliance?

The R5F526TFCGFP#30 includes hardware-assisted IEC60730 Class B safety functions: oscillation-stop detection, ADC disconnection monitoring, clock accuracy measurement, independent watchdog timer (IWDTa), RAM test assist (DOC), CRC calculator (CRCA), and register write protection. These features are documented in the R01DS0407EJ0120 datasheet and enable certified safety firmware implementation-making the R5F526TFCGFP#30 suitable for industrial drive applications requiring functional safety validation.

What package type and pin count does the R5F526TFCGFP#30 use?

The R5F526TFCGFP#30 uses the PLQP0100KB-B package: a 100-pin Low-profile Quad Flat Package with 14 mm × 14 mm body size and 0.5 mm lead pitch. It provides 82 general-purpose I/O pins, 2×5-V tolerant inputs, and 15 high-drive outputs-optimized for industrial motor control PCB layouts requiring robust signal integrity and thermal dissipation. This exact package is specified for the R5F526TFCGFP#30 in Renesas' official documentation.
