For engineers reviewing the R5F526T9AGFN#10 datasheet, R5F526T9AGFN#10 pinout, R5F526T9AGFN#10 application, or R5F526T9AGFN#10 equivalent, this MCU delivers deterministic real-time control for brushless DC and permanent magnet synchronous motor drives, with IEC60730-compliant safety features, on-chip FPU, and simultaneous sampling across three 12-bit A/D units.

Technical Context

The R5F526T9AGFN#10 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 domain clocking (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) and MTU3d (16-bit × 9 channels) support synchronized PWM generation, dead-time insertion, and phase-counting; HRPWM provides 260 ps fine timing adjustment on four GPTW channels; S12ADH offers simultaneous sampling across three 12-bit A/D units (4+4+14 channels) with programmable gain amplifiers and analog comparator (CMPCa, 6 channels) for current sensing and fault detection.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526T9AGFN#10?

The R5F526T9AGFN#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 motor control loops with sub-1 µs interrupt latency. The R5F526T9AGFN#10 sustains full 120 MHz operation across all memory and peripheral interfaces without wait states.

Does the R5F526T9AGFN#10 support CAN FD, and what standard does it comply with?

Yes, the R5F526T9AGFN#10 integrates a CAN FD module compliant with ISO 11898-1:2015 for both standard and extended frames. It supports data rates up to 5 Mbps in FD mode and includes message filtering, FIFO buffering, and error counters. The R5F526T9AGFN#10's CAN FD peripheral operates independently of the CPU via ELC-triggered transfers, ensuring deterministic response to bus events without software overhead.

How many A/D converter channels does the R5F526T9AGFN#10 support, and what sampling capability does it offer?

The R5F526T9AGFN#10 supports 22 total A/D input channels distributed across three 12-bit S12ADH units: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels). Critically, it enables simultaneous sampling across all three units-essential for accurate current reconstruction in 3-phase motor control. Each unit includes dedicated sample-and-hold circuits, and Unit 0/Unit 1 feature programmable-gain amplifiers for direct shunt-resistor sensing.

What PWM resolution and complementary output capabilities does the R5F526T9AGFN#10 provide?

The R5F526T9AGFN#10 delivers 260 ps minimum timing resolution via its 4-channel HRPWM circuit, applied to GPTW0–GPTW3 outputs. It supports 10-channel single-phase, 3-channel 3-phase, and 2-channel 5-phase complementary PWM with automatic dead-time insertion, non-overlapping waveform generation, and synchronous start/stop across channels. These capabilities are hardware-accelerated and managed by MTU3d and GPTWa timers without CPU involvement.

Is the R5F526T9AGFN#10 qualified for automotive or industrial temperature ranges?

Yes, the R5F526T9AGFN#10 is rated for –40°C to +105°C operation (G-version), making it suitable for under-hood automotive applications like HVAC blowers and industrial environments such as factory-floor motor drives. Its qualification includes built-in temperature sensor (±1.0°C accuracy), voltage-monitoring circuits with five selectable thresholds, and IEC60730 Class B self-test features-ensuring reliability across the full specified range.
