Product details
Overview
R5F526TBCGNE#30 from Renesas is a 32-bit RXv3 microcontroller designed for high-performance motor control and industrial inverter applications. It operates at up to 120 MHz, delivers 709 CoreMark, integrates 512 KB code flash, 64 KB SRAM, 16 KB data flash, and features CAN FD, dual 12-bit ADC units with simultaneous sampling, 3-phase complementary PWM (10-channel), and 4-channel HRPWM with 260 ps minimum resolution.
For engineers reviewing the R5F526TBCGNE#30 datasheet, R5F526TBCGNE#30 pinout, R5F526TBCGNE#30 application, or R5F526TBCGNE#30 equivalent, key selection criteria include real-time PWM timing precision, integrated analog front-end for sensorless FOC, IEC60730 safety support, and 100-pin LFQFP package compatibility with industrial drive PCB layouts.
Technical Context
The R5F526TBCGNE#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 motor control interrupt service routines. Its clock system supports PLL-synthesized 120 MHz ICLK with independent PCLKA (120 MHz), PCLKB (60 MHz), PCLKC (120 MHz), and PCLKD (60 MHz) domains for precise peripheral timing.
It integrates dedicated motor control peripherals: GPTWa (8-channel 32-bit timer), MTU3d (9-channel 16-bit timer), HRPWM (4-channel sub-nanosecond edge control), POE3D/POEG for fault-driven output disable, and S12ADH with three sample-and-hold units enabling synchronized current/voltage acquisition across three phases.

Equivalent & Alternatives
The following parts are listed as comparable options for similar motor control MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F526TADGNE#30 | Same RX26T family, identical 100-pin LFQFP package, but with 256 KB code flash and 48 KB SRAM instead of 512 KB/64 KB. | Targeted at cost-sensitive inverter designs where firmware size <256 KB and RAM <48 KB suffice. | Select when application firmware footprint and real-time buffer requirements are lower; retains full peripheral set including HRPWM and S12ADH. |
| R5F566TEBGFE#30 | RX66T Group part in 100-pin LQFP; higher 160 MHz CPU, 1 MB flash, enhanced GPTP timer, but no HRPWM or triple S12ADH units. | Better suited for multi-axis servo drives requiring higher compute throughput, not optimized for ultra-precise single-inverter PWM timing. | Choose for applications needing more flash/RAM headroom and multi-axis coordination, but accept trade-off in sub-ns PWM resolution and simultaneous ADC capability. |
Compared with R5F526TBCGNE#30, R5F526TADGNE#30 offers identical motor control peripherals in a lower-density memory variant, while R5F566TEBGFE#30 trades HRPWM precision and triple ADC synchronization for higher CPU performance and larger memory - making R5F526TBCGNE#30 optimal for single-inverter systems demanding <260 ps PWM edge control and atomic 3-phase current sampling.

FAQ
What is the maximum operating frequency and CoreMark score of the R5F526TBCGNE#30?
The R5F526TBCGNE#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark. This performance level is measured under actual operating conditions with the RXv3 CPU core executing the standardized CoreMark benchmark, confirming its capability to run complex motor control algorithms such as field-oriented control (FOC) within tight real-time deadlines. The R5F526TBCGNE#30 sustains this performance with no wait states on its 512 KB code flash memory.

Yes, the R5F526TBCGNE#30 supports simultaneous sampling across all three S12ADH units (Unit 0, Unit 1, and Unit 2) using shared ADTRG trigger inputs. This capability is confirmed in the datasheet for devices with 64 KB SRAM, enabling atomic acquisition of three-phase current and DC-link voltage - a critical requirement for accurate vector control. The R5F526TBCGNE#30 implements channel-dedicated sample-and-hold circuits in Units 0 and 1 to ensure timing coherence.
What PWM resolution does the HRPWM feature provide on the R5F526TBCGNE#30?
The HRPWM circuit on the R5F526TBCGNE#30 provides a minimum resolution of 260 ps when operating at 120 MHz. This specification is explicitly stated in the datasheet and applies to the four HRPWM channels that enhance GPTWa outputs (GPTW0–GPTW3). The R5F526TBCGNE#30 uses this capability to achieve sub-nanosecond edge placement accuracy, directly supporting low-THD switching in SiC and GaN-based inverter designs.
Which safety standards and built-in self-test features does the R5F526TBCGNE#30 support?
The R5F526TBCGNE#30 includes hardware features aligned with IEC60730 Class B compliance, including oscillation-stoppage detection, RAM test assist (via DOC), CRC calculator (CRCA), independent watchdog timer (IWDTa), and register write protection. These are documented in the official Renesas datasheet R01DS0407EJ0120 and are implemented in silicon - not software libraries. The R5F526TBCGNE#30 also supports Trusted Memory (TM) for secure code execution and Trusted Secure IP Lite for cryptographic operations.
What is the package type and pin count of the R5F526TBCGNE#30?
The R5F526TBCGNE#30 is packaged in a PLQP0100KB-B 100-pin LFQFP (14 × 14 mm, 0.5 mm pitch) with 82 general-purpose I/O pins, two 5-V-tolerant inputs, and dedicated motor control peripherals routed to specific pins including MTIOCx, GTIOCx, and ADTRGx.
