Product details
Overview
R5F526TBCGFP#30 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, featuring a 120 MHz CPU core delivering 709 CoreMark, 512 KB on-chip code flash memory with dual-bank capability, 64 KB SRAM, 16 KB data flash (100,000 write cycles), and integrated CAN FD, high-resolution PWM (260 ps min. resolution), and three 12-bit A/D converter units supporting simultaneous sampling across up to 22 channels.
For engineers reviewing the R5F526TBCGFP#30 datasheet, R5F526TBCGFP#30 pinout, R5F526TBCGFP#30 application, or R5F526TBCGFP#30 equivalent, key selection criteria include its 100-pin LFQFP package with 82 general-purpose I/Os (2 × 5-V tolerant), 3-phase/5-phase complementary PWM generation, IEC60730 safety support (oscillation-stop detection, RAM test assist, CRC, register write protection), and Trusted Secure IP Lite encryption (AES-128/256, TRNG).
Technical Context
The R5F526TBCGFP#30 implements the RXv3 CPU core with single-cycle instruction execution, 113 instructions (including DSP and floating-point), and MPU-based memory protection. Its clock system integrates an 8–24 MHz external crystal oscillator, PLL, and dedicated 120 kHz IWDT oscillator - enabling independent watchdog operation during deep sleep.
Motor control functionality is anchored by the GPTWa (8-channel 32-bit timer), MTU3d (9-channel 16-bit timer), and HRPWM (4-channel high-resolution PWM) modules, all synchronized to PCLKC at up to 120 MHz and coordinated via the Event Link Controller (ELC) to eliminate CPU intervention for trigger chaining between A/D conversion, PWM dead-time compensation, and comparator events.

Does the R5F526TBCGFP#30 support IEC60730 Class B compliance out of the box?
Yes, the R5F526TBCGFP#30 includes hardware features required for IEC60730 Class B certification: oscillation-stop detection, A/D converter self-diagnosis and disconnection detection, clock accuracy measurement circuit, independent watchdog timer (IWDTa), RAM test-assisting function via DOC, CRCA, and register write protection - all documented in the R01DS0407EJ0120 datasheet.
What package type and pin count does the R5F526TBCGFP#30 use?
The R5F526TBCGFP#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. It provides 82 general-purpose I/O pins, including 2 × 5-V tolerant inputs, essential for interfacing with legacy industrial sensors and logic levels.
