It supports IEC60730 functional safety compliance and operates across –40°C to +105°C.
For engineers reviewing the R5F526TFBGFL#30 datasheet, R5F526TFBGFL#30 pinout, R5F526TFBGFL#30 application, or R5F526TFBGFL#30 equivalent, key selection criteria include its 100-pin LFQFP package, dual-bank flash for safe firmware updates, 3-phase/5-phase complementary PWM generation, simultaneous sampling across three 12-bit ADC units, and Trusted Secure IP Lite encryption support.
Technical Context
The R5F526TFBGFL#30 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 up to 60–120 MHz).
Motor control capability is anchored by GPTWa (8-channel 32-bit timer), MTU3d (9-channel 16-bit timer), and HRPWM (4-channel high-resolution PWM) synchronized to PCLKC, with dead-time compensation, phase-counting mode, and ELC-triggered A/D conversion start. Safety features include MPU, Trusted Memory (TM), CRCA, oscillation-stop detection, and RAM test assistance via DOC.

FAQ
What is the maximum operating frequency and CoreMark score of the R5F526TFBGFL#30?
The R5F526TFBGFL#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark in benchmark testing. This performance level is enabled by the RXv3 CPU core's single-cycle instruction execution, 32-bit multiplier/divider, and barrel shifter - providing deterministic timing essential for real-time motor control loops. The R5F526TFBGFL#30 sustains this speed across its full 512 KB flash and 64 KB SRAM with zero wait states.
Does the R5F526TFBGFL#30 support IEC60730 Class B compliance out of the box?
Yes, the R5F526TFBGFL#30 includes hardware features required for IEC60730 Class B certification: oscillation-stop detection, RAM test assistance via DOC, CRCA for data integrity, self-diagnostic ADC and comparator functions, and register write protection. These capabilities are documented in the R01DS0407EJ0120 datasheet and form the foundation for certified safety firmware - though final validation requires application-specific software implementation and third-party assessment. The R5F526TFBGFL#30 itself provides the necessary silicon-level building blocks.
What PWM configurations does the R5F526TFBGFL#30 support for 3-phase motor control?
The R5F526TFBGFL#30 supports 3-phase complementary PWM in both MTU3d (2 output channels) and GPTWa (up to 3 output channels), with automatic dead-time insertion, non-overlapping waveform generation, and synchronous counter clearing. Its HRPWM module further refines timing with 260 ps resolution on GPTW0–GPTW3 outputs - enabling precise gate drive sequencing for SiC/GaN inverters. All PWM units synchronize to PCLKC and accept ELC-triggered events for CPU-free operation during sleep modes. This makes the R5F526TFBGFL#30 highly effective for field-oriented control in industrial drives.
How many ADC channels and sample-and-hold units does the R5F526TFBGFL#30 include?
The R5F526TFBGFL#30 includes three independent 12-bit S12ADH ADC units: Unit 0 (4 channels, 3 sample-and-hold circuits), Unit 1 (4 channels, 3 sample-and-hold circuits), and Unit 2 (14 channels, no dedicated sample-and-hold). This architecture enables true simultaneous sampling across up to six analog inputs - critical for capturing phase currents and DC-link voltage without timing skew in motor control applications. The R5F526TFBGFL#30 leverages this capability via ELC-synchronized triggers from GPTWa or MTU3d timers.
Is the R5F526TFBGFL#30 pin-compatible with other RX26T family members?
No, the R5F526TFBGFL#30 is not pin-compatible with other RX26T variants due to its 100-pin PLQP0100KB-B package - whereas R5F526TDDFL#30 uses a 64-pin HWQFN and R5F526TBGFL#30 uses an 80-pin LFQFP. Pin counts, I/O allocations, and power/ground pin distributions differ across packages. Migration requires PCB redesign. However, the R5F526TFBGFL#30 shares identical peripheral registers, memory map, and toolchain compatibility with the RX26T family - simplifying firmware porting despite the physical layout change.
