It supports IEC60730 safety compliance and includes Trusted Secure IP Lite encryption.
For engineers reviewing the R5F526TBAGFL#30 datasheet, R5F526TBAGFL#30 pinout, R5F526TBAGFL#30 application, or R5F526TBAGFL#30 equivalent, key selection criteria include its 100-pin LFQFP package, dual-bank flash for safe firmware updates, simultaneous sampling across three 12-bit A/D units, 3-phase complementary PWM generation with automatic dead-time insertion, and hardware-accelerated trigonometric functions (TFUv2) for real-time motor vector control.
Technical Context
The R5F526TBAGFL#30 implements the RXv3 CPU core with single-cycle instruction execution at 120 MHz, supporting IEEE 754-compliant single-precision FPU and 16 register banks for fast context switching. Its memory subsystem integrates 512 KB code flash with background programming (BGO), 64 KB zero-wait SRAM with SED, and 16 KB reprogrammable data flash rated for 100,000 erase/write cycles.
Peripheral architecture centers on deterministic real-time control: GPTWa provides eight 32-bit PWM channels with synchronous start/stop and phase-counting mode; MTU3d delivers nine 16-bit timer channels with complementary PWM output and dead-time compensation; HRPWM achieves 260 ps resolution on four GPTW outputs; and ELC enables interrupt-free inter-module event chaining between timers, ADCs, and communication peripherals.

FAQ
What is the maximum operating frequency and CoreMark score of the R5F526TBAGFL#30?
The R5F526TBAGFL#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark performance. This benchmark reflects its RXv3 CPU core efficiency, enabling real-time execution of complex motor control algorithms such as field-oriented control (FOC) and sensorless position estimation without compromising communication or safety tasks. The R5F526TBAGFL#30 sustains this performance with zero-wait-state access to both 512 KB flash and 64 KB SRAM.
Does the R5F526TBAGFL#30 support IEC60730 Class B compliance out of the box?
Yes, the R5F526TBAGFL#30 includes built-in hardware features required for IEC60730 Class B compliance, including oscillation-stop detection, RAM test assist (DOC), analog input disconnection detection, clock accuracy measurement, and CRC calculator (CRCA). These functions reduce software implementation burden and accelerate safety certification. The R5F526TBAGFL#30 also supports register write protection and Trusted Memory to prevent unintended configuration changes during runtime.
What PWM capabilities does the R5F526TBAGFL#30 offer for 3-phase inverter control?
The R5F526TBAGFL#30 provides three complementary PWM subsystems: MTU3d (9 channels, 16-bit), GPTWa (8 channels, 32-bit), and HRPWM (4 channels, 260 ps resolution). It supports 3-phase complementary PWM with automatic dead-time insertion, phase-counting mode for encoder emulation, and synchronous start/stop across all channels. These features enable precise gate timing for SiC/GaN inverters and eliminate CPU overhead in critical timing paths. The R5F526TBAGFL#30's HRPWM ensures sub-nanosecond edge placement accuracy essential for high-efficiency motor drives.
How many A/D converter channels does the R5F526TBAGFL#30 support, and what sampling modes are available?
The R5F526TBAGFL#30 integrates three 12-bit S12ADH units totaling 22 channels (4+4+14), with channel-dedicated sample-and-hold circuits in Units 0 and 1. It supports simultaneous sampling across all units using hardware triggers from GPTWa or MTU3d, scan modes (single, continuous, 3-group), and group-priority control. Minimum conversion time is 0.9 µs per channel at 60 MHz ADCLK. The R5F526TBAGFL#30 uses these ADC resources for real-time current sensing, DC-link voltage monitoring, and temperature acquisition in motor control applications.
Is the R5F526TBAGFL#30 pin-compatible with other RX26T family members?
No, the R5F526TBAGFL#30 is not pin-compatible with other RX26T variants due to its 100-pin PLQP0100KB-B package, whereas alternatives like R5F526TADFL#30 use 64-pin HWQFN. Pinouts differ significantly across package options, and peripheral channel allocation varies with pin count. Engineers must verify I/O mapping, power pin placement, and debug interface routing for each specific variant. The R5F526TBAGFL#30's full feature set-including all 83 GPIOs, dual CAN FD pins, and HRPWM outputs-is only available in the 100-pin configuration.
