Renesas R5F526T9BGNE#30

Overview

R5F526T9BGNE#30 from Renesas is a 32-bit RXv3 core microcontroller optimized for motor control, featuring 120 MHz operation, 512 KB on-chip code flash, 64 KB SRAM, and integrated CAN FD, high-resolution PWM (260 ps min resolution), and dual-bank flash for safe firmware updates - deployed in industrial inverters and servo drives.

For engineers reviewing the R5F526T9BGNE#30 datasheet, R5F526T9BGNE#30 pinout, R5F526T9BGNE#30 application, or R5F526T9BGNE#30 equivalent, key selection criteria include its 100-pin LFQFP package, 3-phase/5-phase complementary PWM support, IEC60730 safety features, and Trusted Secure IP Lite encryption - all validated for real-time motor control timing and functional safety compliance.

Technical Context

The R5F526T9BGNE#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and 16-register bank save for fast context switching in interrupt-heavy motor control loops. It integrates ELC (Event Link Controller) to trigger timer, ADC, and PWM actions without CPU intervention - enabling deterministic sub-microsecond response to hardware events.

Its clock system combines an 8–24 MHz external crystal with PLL for 120 MHz ICLK, plus independent PCLKA/PCLKC domains synchronized at up to 120 MHz for GPTW/HRPWM and MTU3d timers. The HRPWM circuit achieves 260 ps timing resolution by phase-shifting GPTW outputs using dedicated delay units referenced to PCLKC.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526T9BGNE#30?

The R5F526T9BGNE#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark points under benchmark conditions. This performance stems from its RXv3 CPU core with single-cycle instruction execution, 32-bit multiplier/divider, and barrel shifter - all verified in Renesas R01DS0407EJ0120 Rev.1.20. The R5F526T9BGNE#30 sustains this speed across its 512 KB flash and 64 KB SRAM with zero wait states.

Does the R5F526T9BGNE#30 support IEC60730 Class B compliance out of the box?

Yes, the R5F526T9BGNE#30 includes hardware-level IEC60730 safety features: oscillation-stoppage detection, RAM test assist (via DOC), CRC calculator (CRCA), independent watchdog timer (IWDTa), and register write protection. These are documented in Section 1.1 and Section 22 of R01DS0407EJ0120 Rev.1.20. No external components are required to implement the core self-test suite for Class B certification - the R5F526T9BGNE#30 executes these checks autonomously.

What PWM resolution and configurations does the R5F526T9BGNE#30 support for motor control?

The R5F526T9BGNE#30 supports 3-phase, 5-phase, and single-phase complementary PWM via its 8-channel 32-bit GPTWa and 4-channel HRPWM, achieving a minimum timing resolution of 260 ps at 120 MHz. It delivers 10 single-phase, 3 three-phase, or 2 five-phase complementary outputs with automatic dead-time insertion - confirmed in Table 1.1 and Section 18.3 of R01DS0407EJ0120 Rev.1.20. This enables precise gate driving for SiC and GaN inverters.

How many ADC channels and sample-and-hold units does the R5F526T9BGNE#30 include?

The R5F526T9BGNE#30 includes 22 total 12-bit ADC input channels distributed across three S12ADH units: Unit 0 (4 channels, 3 sample-and-hold circuits), Unit 1 (4 channels, 3 sample-and-hold circuits), and Unit 2 (14 channels). This configuration supports true simultaneous sampling across all three units - a capability explicitly stated for "products with 64 Kbytes of RAM" like the R5F526T9BGNE#30 in Section 1.1 and page 9 of R01DS0407EJ0120 Rev.1.20.

What package type and pin count does the R5F526T9BGNE#30 use?

The R5F526T9BGNE#30 uses the PLQP0100KB-B package: a 100-pin Low-Profile Quad Flat Package measuring 14 × 14 mm with 0.5 mm pitch. This matches the "100-pin LFQFP" variant defined in Table 1.2 of R01DS0407EJ0120 Rev.1.20 and supports 82 general-purpose I/O pins, including 2 × 5-V tolerant inputs and 15 large-current outputs - essential for direct interfacing with gate drivers and sensors.
