For engineers reviewing the R5F526T9AGND#30 datasheet, R5F526T9AGND#30 pinout, R5F526T9AGND#30 application, or R5F526T9AGND#30 equivalent, key selection criteria include its 120 MHz GPTWa timer with 3-phase/5-phase complementary PWM, dual-bank flash for safe firmware updates, Trusted Secure IP Lite encryption, and hardware-accelerated trigonometric functions (TFUv2) for real-time motor vector control.

Technical Context

The R5F526T9AGND#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 in interrupt-heavy motor control loops. Its clock system integrates PLL, HOCO (16/18/20 MHz), LOCO (240 kHz), and IWDT-dedicated 120 kHz oscillator - enabling independent timing domains for PCLKA (120 MHz), PCLKB (60 MHz), PCLKC (120 MHz), and PCLKD (60 MHz).

Peripheral coordination is managed via Event Link Controller (ELC), supporting 183 internal event signals to trigger timer starts/stops, A/D conversion, or port output changes without CPU intervention. The MCU integrates MTU3d (9-channel 16-bit timer) and GPTWa (8-channel 32-bit timer) with synchronized dead-time generation, POE3D/POEG for fault-driven waveform shutdown, and S12ADH with three sample-and-hold units for simultaneous current sensing.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526T9AGND#30?

The R5F526T9AGND#30 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 optimized pipeline - enabling deterministic real-time response in motor control loops without compromising on computational throughput.

Does the R5F526T9AGND#30 support IEC60730 Class B compliance out of the box?

Yes, the R5F526T9AGND#30 includes dedicated hardware features for IEC60730 Class B compliance: oscillation-stop detection, RAM test assist (DOC), CRC calculator (CRCA), register write protection, A/D converter disconnection diagnostics, and clock accuracy measurement circuit. These are documented in the R01DS0407EJ0120 datasheet and require no external components to implement required self-tests.

What PWM resolution does the R5F526T9AGND#30 achieve, and how is it implemented?

The R5F526T9AGND#30 achieves a minimum PWM timing resolution of 260 ps using its High-Resolution PWM (HRPWM) module, which operates on GPTW0–GPTW3 outputs. This is realized by leveraging the 120 MHz system clock domain and fine-grained phase-shift control - enabling precise dead-time insertion and reduced switching losses in high-frequency inverter designs.

How many analog-to-digital converter channels does the R5F526T9AGND#30 support, and what sampling architecture does it use?

The R5F526T9AGND#30 supports up to 22 analog input channels via its S12ADH module: 4 channels in Unit 0, 4 in Unit 1, and 14 in Unit 2. It uses three independent sample-and-hold circuits - two with 3-channel capability (Units 0 and 1) and one with 14-channel capability (Unit 2) - enabling truly simultaneous sampling across multiple current/voltage sensing paths.

Is the R5F526T9AGND#30 pin-compatible with other RX26T group MCUs in the same package?

Yes, the R5F526T9AGND#30 is pin-compatible with other 100-pin RX26T MCUs using the PLQP0100KB-B package (e.g., R5F526TADGND#30). All share identical pin assignments for power, reset, clocks, peripherals, and GPIOs - allowing hardware reuse across different memory/configurations within the RX26T family without PCB redesign.
