For engineers reviewing the R5F526TBBGFM#10 datasheet, R5F526TBBGFM#10 pinout, R5F526TBBGFM#10 application, or R5F526TBBGFM#10 equivalent, key selection criteria include its 120 MHz GPTWa timer with 10-channel single-phase complementary PWM, 260 ps HRPWM resolution, dual-bank flash for safe firmware updates, Trusted Secure IP Lite encryption, and 100-pin LFQFP package with 82 general-purpose I/O pins including 5-V tolerant inputs.

Technical Context

The R5F526TBBGFM#10 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and 16-register bank save for fast context switching. 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 capability is anchored by three synchronized timer subsystems: MTU3d (9-channel 16-bit) for 3-phase PWM with automatic dead-time insertion, GPTWa (8-channel 32-bit) supporting 3-/5-phase complementary modes, and HRPWM (4-channel) delivering 260 ps timing resolution. All timers synchronize with PCLKC and support ELC-triggered operation without CPU intervention.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TBBGFM#10?

The R5F526TBBGFM#10 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark points under benchmark conditions. This performance stems from the RXv3 CPU core's single-cycle instruction execution, 32-bit multiplier/divider, and barrel shifter-enabling deterministic real-time motor control loop execution within tight timing budgets. The R5F526TBBGFM#10 maintains this performance across its full operating temperature range (–40°C to +105°C).

Does the R5F526TBBGFM#10 support CAN FD, and what standard does it comply with?

Yes, the R5F526TBBGFM#10 integrates a CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames at data rates up to 5 Mbps. It includes built-in message filtering, transmit/receive buffers, and error handling logic-enabling robust communication in electric vehicle auxiliary systems and industrial automation networks where legacy CAN bandwidth limitations are prohibitive.

How many ADC channels does the R5F526TBBGFM#10 support, and what is its sampling capability?

The R5F526TBBGFM#10 supports 21 total channels across three 12-bit S12ADH units: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels). It enables simultaneous sampling across all three units using hardware triggers from MTU3d or GPTWa timers-critical for vector-controlled motor drives requiring phase-current and DC-link voltage acquisition within a single control cycle. Minimum conversion time is 0.9 µs per channel at 60 MHz ADCLK.

What safety certifications and features does the R5F526TBBGFM#10 include for IEC60730 compliance?

The R5F526TBBGFM#10 includes dedicated hardware features for IEC60730 Class B compliance: oscillation-stop detection, A/D converter disconnection detection, clock frequency accuracy measurement circuit, independent watchdog timer (IWDTa), RAM test-assisting function via DOC, CRCA, and register write protection. These are implemented in silicon-not software-ensuring deterministic, fail-safe behavior during runtime self-tests required for household appliance certification.

What is the package type and pin count of the R5F526TBBGFM#10?

The R5F526TBBGFM#10 uses the PLQP0100KB-B package: a 100-pin Low-Profile Quad Flat Package measuring 14 mm × 14 mm with 0.5 mm pitch and an exposed thermal pad. It provides 82 general-purpose I/O pins-including 2 × 5-V tolerant inputs, 15 large-current outputs, and dedicated MTU/GPTW waveform I/O-making it suitable for high-density motor control PCB layouts requiring thermal efficiency and noise immunity.
