Overview
R5F526T9ADFP#50 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, 64 KB SRAM, 16 KB data flash, integrated CAN FD interface, and hardware-accelerated 3-phase/5-phase complementary PWM generation with 260 ps HRPWM timing resolution.
For engineers reviewing the R5F526T9ADFP#50 datasheet, R5F526T9ADFP#50 pinout, R5F526T9ADFP#50 application, or R5F526T9ADFP#50 equivalent, this MCU is selected for high-precision real-time motor control where deterministic interrupt latency, simultaneous A/D sampling across three units, trusted secure IP Lite encryption, and IEC60730-compliant safety features are required.
Technical Context
The R5F526T9ADFP#50 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 loops. Its clock system supports independent PCLKA (up to 120 MHz), PCLKC (up to 120 MHz for GPTW/HRPWM counters), and PCLKD (up to 60 MHz for S12ADH) domains enabling precise peripheral timing isolation.
It integrates dual-bank flash for safe firmware updates during operation, 12-bit S12ADH ADC with three sample-and-hold units (4+4+14 channels), six-channel analog comparator (CMPCa), two 12-bit DACs usable as comparator references, and Trusted Secure IP Lite with AES-128/256, TRNG, and key protection - all validated for IEC60730 Class B compliance.
