Product details
Overview
R5F526TBCGFM#10 from Renesas is a 32-bit RXv3 microcontroller optimized for motor control, featuring a 120 MHz CPU core, 512 KB on-chip code flash, 64 KB SRAM, 16 KB data flash, integrated CAN FD interface, and 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 R5F526TBCGFM#10 datasheet, R5F526TBCGFM#10 pinout, R5F526TBCGFM#10 application, or R5F526TBCGFM#10 equivalent, key selection criteria include its 120 MHz GPTWa timer with 3-phase/5-phase complementary PWM, dual-bank flash for safe firmware updates, Trusted Secure IP Lite encryption, and hardware-accelerated trigonometric functions (TFUv2) for real-time motor algorithms.
Technical Context
The R5F526TBCGFM#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. Its clock system integrates PLL, HOCO (16/18/20 MHz), LOCO (240 kHz), and IWDT-dedicated 120 kHz oscillator - enabling precise timing isolation for safety-critical watchdog operation.
Motor control is enabled by tightly coupled peripherals: MTU3d (9-channel 16-bit timer) and GPTWa (8-channel 32-bit timer) both synchronized to PCLKC at up to 120 MHz, with HRPWM overlay providing sub-nanosecond edge placement. The ELC links A/D conversion triggers, PWM dead-time compensation, and comparator events without CPU intervention.
