For engineers reviewing the R5F526TBCGFL#30 datasheet, R5F526TBCGFL#30 pinout, R5F526TBCGFL#30 application, or R5F526TBCGFL#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 R5F526TBCGFL#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 up to 60 MHz, PCLKC/PCLKD up to 120/60 MHz).

Motor control capability is anchored by GPTWa (32-bit × 8 channels), MTU3d (16-bit × 9 channels), and HRPWM (4 channels) with synchronized dead-time generation, phase-counting mode, and ELC-triggered A/D conversion start. Safety features include MPU, Trusted Memory (TM), register write protection, CRCA, and oscillation-stop detection - all aligned with IEC60730 Class B requirements.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TBCGFL#30?

The R5F526TBCGFL#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark points under benchmark conditions. This performance stems from its RXv3 CPU core with single-cycle instruction execution, 32-bit multiplier/divider, and barrel shifter - enabling deterministic real-time response in motor control loops. The R5F526TBCGFL#30 sustains this speed across its full 512 KB flash and 64 KB SRAM with zero wait states.

Does the R5F526TBCGFL#30 support IEC60730 Class B compliance out of the box?

Yes, the R5F526TBCGFL#30 includes dedicated hardware features required for IEC60730 Class B certification: oscillation-stop detection, ADC disconnection monitoring, RAM test assistance via DOC, CRCA for data integrity, register write protection, and independent watchdog timer with window function. These are documented in the R01DS0407EJ0120 datasheet and do not require external components to implement basic self-test routines. The R5F526TBCGFL#30 is intended as a foundational element in certified safety firmware stacks.

What ADC configuration does the R5F526TBCGFL#30 provide, and how many channels support simultaneous sampling?

The R5F526TBCGFL#30 integrates three 12-bit S12ADH ADC units: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels), totaling 22 input channels. All three units support truly simultaneous sampling when triggered by a common ELC or timer event - critical for capturing correlated voltage, current, and position signals in motor control. Each unit includes dedicated sample-and-hold circuits (3 per unit for Units 0/1), and conversion time is as low as 0.9 µs per channel at 60 MHz ADCLK.

What is the role of the Event Link Controller (ELC) in the R5F526TBCGFL#30, and how many events does it support?

The Event Link Controller (ELC) in the R5F526TBCGFL#30 enables autonomous, CPU-free inter-module triggering - for example, an MTU3d counter overflow can directly initiate ADC conversion, which then triggers DMACA data transfer, all without interrupt latency. It supports 183 internal event signals (including timer matches, ADC completions, comparator outputs, and communication flags) that can be freely routed to 16 target modules. This offloads timing-critical sequencing from firmware, improving determinism and reducing CPU utilization in the R5F526TBCGFL#30.

Is the R5F526TBCGFL#30 pin-compatible with other RX26T variants, and what package does it use?

Yes, the R5F526TBCGFL#30 uses the PLQP0100KB-B package - a 100-pin LFQFP (14 mm × 14 mm, 0.5 mm pitch) - and is pin-compatible with all other RX26T Group members in the same 100-pin configuration, including R5F526TADGFL#30 and R5F526TBDGFL#30. Pin mappings for power, clocks, reset, peripherals, and GPIOs are identical across these variants; only memory size and some peripheral enablement differ in silicon - allowing shared PCB design and firmware portability within the RX26T family.
