Renesas R5F526TFAGNE#50

Overview

R5F526TFAGNE#50 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, featuring 120 MHz operation, 512 KB on-chip code flash, 64 KB SRAM, 16 KB data flash, integrated CAN FD, and 3-phase complementary PWM with dead-time control. It supports IEC60730 safety compliance and includes hardware encryption (AES-128/256) and a temperature sensor (±1.0°C).

For engineers reviewing the R5F526TFAGNE#50 datasheet, R5F526TFAGNE#50 pinout, R5F526TFAGNE#50 application, or R5F526TFAGNE#50 equivalent, key selection considerations include its 100-pin LFQFP package, dual-bank flash for safe firmware updates, 260 ps HRPWM timing resolution, simultaneous sampling across three 12-bit ADC units, and Trusted Secure IP Lite for secure boot and key management.

Technical Context

The R5F526TFAGNE#50 implements the RXv3 CPU core with single-cycle instruction execution, 113 instructions, IEEE 754-compliant FPU, and MPU-based memory protection. Its clock system integrates PLL, 240-kHz LOCO, and 120-kHz IWDT-dedicated oscillator, enabling independent domain clocks (ICLK up to 120 MHz, PCLKA up to 120 MHz, PCLKB up to 60 MHz).

Motor control is enabled by tightly coupled peripherals: GPTWa (32-bit × 8 channels), MTU3d (16-bit × 9 channels), HRPWM (4 channels, 260 ps min. resolution), POE3D/POEG for output disable, and S12ADH with three sample-and-hold units supporting simultaneous sampling of up to 7 analog channels - all coordinated via ELC without CPU intervention.

FAQ

What is the maximum operating frequency and CPU architecture of the R5F526TFAGNE#50?

The R5F526TFAGNE#50 operates at a maximum frequency of 120 MHz using the 32-bit RXv3 CPU core. It delivers 709 CoreMark performance, supports single-cycle instruction execution, includes an IEEE 754-compliant FPU, and features a 4-Gbyte linear address space with 16 general-purpose 32-bit registers. The core also implements a collective register bank save function and memory protection unit (MPU) for robust real-time operation.

Does the R5F526TFAGNE#50 support IEC60730 functional safety compliance?

Yes, the R5F526TFAGNE#50 includes multiple hardware features to accelerate IEC60730 Class B certification: oscillation-stop detection, self-diagnostic A/D converter functions, clock frequency accuracy measurement, independent watchdog timer (IWDTa) with window function, RAM test-assisting function via DOC, CRC calculator (CRCA), and register write protection. These are documented in the R01DS0407EJ0120 datasheet and supported by Renesas' safety application notes.

What are the ADC capabilities of the R5F526TFAGNE#50, and how many channels support simultaneous sampling?

The R5F526TFAGNE#50 integrates three 12-bit S12ADH ADC units: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels). It supports true simultaneous sampling across all three units - enabling concurrent acquisition of up to 7 analog signals (e.g., three-phase currents and DC-link voltage) with sub-microsecond inter-channel skew. Minimum conversion time is 0.9 µs per channel at 60 MHz ADCLK.

What PWM resolution and channel count does the R5F526TFAGNE#50 provide for motor control?

The R5F526TFAGNE#50 provides 8-channel 32-bit GPTWa timers and 9-channel 16-bit MTU3d timers, plus 4-channel High-Resolution PWM (HRPWM) with a minimum timing resolution of 260 ps at 120 MHz. It supports 10 single-phase, 3 three-phase, and 2 five-phase complementary PWM outputs - all with programmable dead time, synchronous start/stop, and ELC-triggered operation for precise inverter gate driving.

Is the R5F526TFAGNE#50 pin-compatible with other RX26T group MCUs?

No, the R5F526TFAGNE#50 is not pin-compatible with other RX26T variants due to its 100-pin LFQFP (PLQP0100KB-B) package and full peripheral complement. Lower-pin-count variants like R5F526TDDDFP#30 (64-pin HWQFN) have different pin mappings, reduced I/O count (48 vs. 82), and fewer ADC/SPI/CAN resources. PCB layout must be specific to the R5F526TFAGNE#50's 100-pin footprint and thermal pad requirements.
