Product details

Overview

R5F526TBAGFN#10 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control and industrial inverter applications, featuring 120 MHz operation, 512 KB on-chip code flash, 64 KB SRAM, 16 KB data flash, integrated CAN FD interface, and 4-channel high-resolution PWM with 260 ps timing resolution. It supports IEC60730 safety compliance and operates across –40°C to +105°C.

For engineers reviewing the R5F526TBAGFN#10 datasheet, R5F526TBAGFN#10 pinout, R5F526TBAGFN#10 application, or R5F526TBAGFN#10 equivalent, key selection considerations include its 100-pin HWQFN package (PLQP0100KB-B), dual-bank flash for safe firmware updates, simultaneous sampling across three 12-bit A/D units, and hardware-accelerated trigonometric functions (TFUv2) for real-time motor vector control.

Technical Context

The R5F526TBAGFN#10 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 interrupt-heavy motor control loops. Its clock system integrates PLL, HOCO (16/18/20 MHz), LOCO (240 kHz), and IWDT-dedicated 120 kHz oscillator - enabling precise timing separation between CPU (ICLK @ 120 MHz), peripheral modules (PCLKA @ 120 MHz), and ADC (ADCLK @ 60 MHz).

Hardware acceleration includes GPTWa (8-channel 32-bit timer) with complementary PWM generation, MTU3d (9-channel 16-bit timer) for 3-phase inverter control, HRPWM (4 channels) for sub-nanosecond dead-time adjustment, and TFUv2 for sine/cosine/arctangent computation without software overhead. Safety features include MPU, Trusted Memory (TM), CRCA, and independent watchdog timer (IWDTa) with window function.

Equivalent & Alternatives

The following parts are listed as comparable options for similar motor control MCU applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
R5F526TADFN#10	Same RX26T family, 64-pin HWQFN (PWQN0064KF-A), 256 KB flash, 48 KB SRAM, 2× 12-bit A/D units (7+8 channels)	Targeted at space-constrained single-motor drives with reduced analog channel count and lower memory footprint	Select when board area is critical and full 100-pin I/O or triple A/D sampling is unnecessary.
R5F566TEADFP#30	RX66T family, 100-pin LQFP, 160 MHz CPU, 1 MB flash, 256 KB SRAM, enhanced GPTP (64-bit timers), no HRPWM	Higher-performance variant for multi-axis servo drives requiring faster FOC loops and larger code storage	Choose when >120 MHz deterministic timing, larger memory, or advanced encoder interfaces (e.g., EnDat 2.2) are required.

Compared with R5F526TBAGFN#10, the R5F526TADFN#10 offers identical peripheral architecture in a smaller package but sacrifices A/D sampling depth and flash capacity, while the R5F566TEADFP#30 delivers higher clock speed and memory headroom at the cost of increased power and absence of sub-nanosecond PWM resolution - making R5F526TBAGFN#10 optimal for thermally constrained, safety-certified inverter designs demanding precision timing.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F526TBAGFN#10?

The R5F526TBAGFN#10 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark performance. This benchmark reflects its RXv3 CPU core's efficient pipeline, single-cycle instruction execution, and integrated FPU - enabling deterministic execution of complex motor control algorithms within tight timing budgets. The R5F526TBAGFN#10 sustains this performance with zero-wait-state access to both 512 KB flash and 64 KB SRAM.

Does the R5F526TBAGFN#10 support IEC60730 Class B compliance out of the box?

Yes, the R5F526TBAGFN#10 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, A/D disconnection monitoring, and register write protection. These capabilities are documented in Renesas Application Note R01AN4223JJ0100 and require no external components to satisfy mandatory self-test requirements - simplifying certification for R5F526TBAGFN#10-based designs.

What PWM resolution does the R5F526TBAGFN#10 achieve, and how is it implemented?

The R5F526TBAGFN#10 achieves a minimum PWM timing resolution of 260 ps using its 4-channel High-Resolution PWM (HRPWM) module, which operates in conjunction with the GPTWa timer. This resolution is realized by interpolating between main clock cycles (120 MHz → 8.33 ns period) using fine-phase delay logic - enabling precise dead-time control critical for SiC/GaN inverter efficiency and EMI reduction. The R5F526TBAGFN#10 applies this resolution exclusively to GPTW0–GPTW3 outputs, not MTU3d or other timers.

How many A/D converter channels does the R5F526TBAGFN#10 support, and what sampling modes are available?

The R5F526TBAGFN#10 supports 22 total A/D input channels across three independent 12-bit S12ADH units: Unit 0 (4 channels), Unit 1 (4 channels), and Unit 2 (14 channels). It enables simultaneous sampling across all three units via hardware synchronization, plus scan modes (single, continuous, 3-group), group priority control, and double-trigger mode for redundancy. Sampling time per channel is individually configurable, and conversion results can be filtered or compared digitally - all features confirmed in R01DS0407EJ0120 Section 19.

Is the R5F526TBAGFN#10 pin-compatible with other RX26T devices, and what package does it use?

The R5F526TBAGFN#10 uses the PLQP0100KB-B package: a 100-pin HWQFN with 14 × 14 mm body and 0.5 mm pitch. It is not pin-compatible with smaller RX26T variants (e.g., 64-pin PWQN0064KF-A or 48-pin PWQN0048KC-A) due to differing pin counts and I/O allocations. Pin compatibility is limited to other 100-pin RX26T members like R5F526TBAFNL#10 (same package, different temp grade), but even then, minor signal mapping differences may exist - always verify against the specific device's pin function table in R01DS0407EJ0120.
