Renesas R5F526TFAGFP#10

Overview

R5F526TFAGFP#10 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, featuring a 120 MHz CPU core, 512 KB on-chip code flash, 64 KB SRAM, 16 KB data flash, integrated CAN FD interface, and hardware-accelerated 3-phase complementary PWM generation with dead-time control.

For engineers reviewing the R5F526TFAGFP#10 datasheet, R5F526TFAGFP#10 pinout, R5F526TFAGFP#10 application, or R5F526TFAGFP#10 equivalent, key selection considerations include its 100-pin LFQFP package, 120 MHz real-time PWM timing resolution (260 ps HRPWM), IEC60730 safety support, dual-bank flash for safe firmware updates, and integrated analog peripherals including three 12-bit A/D units with simultaneous sampling capability.

Technical Context

The R5F526TFAGFP#10 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and collective register bank save for fast interrupt response. It integrates dedicated motor control peripherals including 8-channel 32-bit GPTWa timers supporting 10-channel single-phase, 3-channel 3-phase, and 2-channel 5-phase complementary PWM modes.

Its clock system combines an 8–24 MHz external crystal oscillator with PLL synthesis to deliver 120 MHz ICLK, while PCLKA/PCLKC run at up to 120 MHz for peripheral timing-enabling synchronized operation of MTU3d, GPTWa, and HRPWM modules. The device supports event-driven operation via ELC, eliminating CPU intervention for timer-triggered ADC conversions and PWM waveform updates.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TFAGFP#10?

The R5F526TFAGFP#10 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark in benchmark testing. This performance stems from its RXv3 CPU core with single-cycle instruction execution, on-chip 32-bit multiplier/divider, and barrel shifter-enabling deterministic real-time response for motor control loops. The R5F526TFAGFP#10 sustains this speed across its full 512 KB flash and 64 KB SRAM with no wait states.

Does the R5F526TFAGFP#10 support IEC60730 Class B compliance?

Yes, the R5F526TFAGFP#10 includes multiple hardware features required for IEC60730 Class B compliance: oscillation-stop detection, RAM test assist (DOC), CRC calculator (CRCA), independent watchdog timer (IWDTa) with window function, register write protection, and self-diagnostic A/D converter functions. These are documented in the R01DS0407EJ0120 datasheet and validated for use in safety-critical motor control applications. The R5F526TFAGFP#10 implements them without external components.

What package type and pin count does the R5F526TFAGFP#10 use?

The R5F526TFAGFP#10 uses a 100-pin Low-profile Quad Flat Package (LFQFP) with designation PLQP0100KB-B: 14 mm × 14 mm body, 0.5 mm lead pitch, and exposed thermal pad. It provides 82 general-purpose I/O pins, two 5-V tolerant inputs, and dedicated motor control peripherals including MTU3d and GPTWa PWM outputs. This package is specified in the RX26T Group datasheet revision 1.20 and is RoHS compliant.

How many A/D converter channels does the R5F526TFAGFP#10 support, and what is their configuration?

The R5F526TFAGFP#10 supports 22 total 12-bit A/D converter channels across three independent S12ADH units: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels). Units 0 and 1 each include three sample-and-hold circuits for simultaneous sampling-critical for three-phase current reconstruction. Minimum conversion time is 0.9 µs per channel at 60 MHz ADCLK. All units support software, timer-synchronized, and external triggering. This configuration is confirmed for the 64 KB RAM variant, which the R5F526TFAGFP#10 implements.

What communication interfaces are integrated into the R5F526TFAGFP#10?

The R5F526TFAGFP#10 integrates CAN FD (ISO 11898-1:2015 compliant), four SCI channels (SCIk/SCIh), three RSCI channels with LIN and Manchester encoding, one I2C bus interface (RIICa, 400 kbps), one I3C bus interface (RI3C, SDR mode), and two SPI interfaces (RSPId and RSPIA, up to 30 Mbps). These interfaces support mixed-protocol industrial networks-e.g., CAN FD for system-level coordination and RSPI for local sensor daisy-chaining. All are detailed in the R01DS0407EJ0120 datasheet sections 1.1 and 7.
