Product details
Overview
R5F526TBCGFN#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), integrated CAN FD interface (ISO 11898-1:2015), and hardware-accelerated 3-phase complementary PWM generation for IGBT/MOSFET gate driving.
For engineers reviewing the R5F526TBCGFN#30 datasheet, R5F526TBCGFN#30 pinout, R5F526TBCGFN#30 application, or R5F526TBCGFN#30 equivalent, key selection considerations include its 100-pin LFQFP package with 82 general-purpose I/Os (2 × 5-V tolerant), 260 ps high-resolution PWM timing resolution, simultaneous sampling across three 12-bit A/D converter units, and Trusted Secure IP Lite encryption supporting AES-128/256 for firmware integrity in safety-critical systems.
Technical Context
The R5F526TBCGFN#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 real-time motor control loops. Its clock system integrates an 8–24 MHz external crystal oscillator, internal 240 kHz LOCO and selectable 16/18/20 MHz HOCO, and PLL for stable 120 MHz ICLK with independent PCLKA/PCLKB/PCLKC/PCLKD domains enabling concurrent high-speed peripheral operation.
Peripheral integration centers on deterministic timing control: GPTWa (8-channel 32-bit timer) and MTU3d (9-channel 16-bit timer) support synchronized 3-phase/5-phase complementary PWM with programmable dead time and automatic non-overlap enforcement; HRPWM adds 260 ps edge placement resolution to GPTW0–GPTW3 outputs; S12ADH provides three independent 12-bit A/D units (4+4+14 channels) with sample-and-hold for simultaneous current/voltage sensing in vector-controlled drives.
