For engineers reviewing the R5F526T9AGNE#30 datasheet, R5F526T9AGNE#30 pinout, R5F526T9AGNE#30 application, or R5F526T9AGNE#30 equivalent, key selection criteria include its 120 MHz GPTWa timer with 10-channel single-phase complementary PWM, 260 ps HRPWM timing resolution, IEC60730-compliant self-test features, and PLQP0100KB-B 100-pin QFP package with 5-V-tolerant I/Os.

Technical Context

The R5F526T9AGNE#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 real-time motor control loops. It integrates dual-bank flash enabling background programming while executing from alternate bank, and supports simultaneous sampling across three 12-bit A/D units (S12ADH) for synchronized current/voltage sensing.

Its peripheral architecture centers on event-driven operation via the Event Link Controller (ELC), eliminating CPU intervention for timer-triggered ADC conversions, PWM updates, and comparator interrupts. Clock domains are strictly partitioned: PCLKA at up to 120 MHz for MTU3d/GPTWa/HRPWM, PCLKC at up to 120 MHz for counter reference clocks, and PCLKD at up to 60 MHz for ADCLK - ensuring deterministic timing for safety-critical control paths.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526T9AGNE#30?

The R5F526T9AGNE#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark performance. This benchmark reflects its RXv3 CPU core efficiency in real-world embedded control workloads. The R5F526T9AGNE#30 sustains this performance with zero-wait-state access to both 512 KB code flash and 64 KB SRAM, enabling deterministic execution of complex motor control algorithms without pipeline stalls.

Does the R5F526T9AGNE#30 support IEC60730 Class B compliance out of the box?

Yes, the R5F526T9AGNE#30 includes dedicated hardware features for IEC60730 Class B compliance: oscillation-stop detection, RAM test assist via DOC, CRCA for data integrity, independent watchdog timer (IWDTa) with window function, register write protection, and self-diagnostic A/D converter disconnection detection. These are documented in Renesas R01DS0407EJ0120 Rev.1.20 Section 1.1 and Application Note R01AN5017JJ0100, enabling certified implementations without external safety components.

What package type and pin count does the R5F526T9AGNE#30 use?

The R5F526T9AGNE#30 uses the PLQP0100KB-B package: a 100-pin low-profile quad flat package measuring 14 × 14 mm with 0.5 mm pitch and an exposed thermal pad. This package supports the full I/O complement of the RX26T Group, including 82 general-purpose I/O pins (with 5-V tolerance on two pins), and is rated for operation from –40°C to +105°C - matching industrial motor drive thermal requirements.

How many ADC channels and what resolution does the R5F526T9AGNE#30 provide?

The R5F526T9AGNE#30 integrates three 12-bit S12ADH analog-to-digital converter units totaling 22 channels: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels). Each unit includes dedicated sample-and-hold circuits, and minimum conversion time is 0.9 µs per channel when ADCLK runs at 60 MHz. This configuration enables simultaneous sampling across all units for synchronized current/voltage acquisition in 3-phase motor control.

What communication interfaces are integrated into the R5F526T9AGNE#30?

The R5F526T9AGNE#30 integrates CAN FD (ISO 11898-1:2015 compliant), four SCI channels (SCIk/SCIh), three RSCI channels with LIN/Manchester support, one I2C bus interface (RIICa) at 400 kbps, one I3C bus interface (RI3C) in SDR mode, and two SPI interfaces (RSPId and RSPIA) with transfer rates up to 30 Mbps. These interfaces support multi-protocol industrial connectivity - including CAN FD for real-time torque commands and RSCI with HBS for home automation subsystems.
