Overview
R5F526TFDGFP#30 from Renesas is a 120-MHz 32-bit RXv2 microcontroller with single-precision IEEE-754 FPU, 4 MB on-chip code flash, 512 KB SRAM (no wait states), and integrated IEEE 1588-compliant Ethernet MAC - designed for industrial Ethernet gateways requiring deterministic real-time control, secure firmware updates, and multi-protocol connectivity.
For engineers reviewing the R5F526TFDGFP#30 datasheet, R5F526TFDGFP#30 pinout, R5F526TFDGFP#30 application, or R5F526TFDGFP#30 equivalent, this MCU delivers verified 240 DMIPS performance, dual 12-bit ADCs (21-channel + 8-channel), full-speed USB 2.0 with battery charging support, CAN FD-capable ISO 11898-1 interfaces, and hardware AES/SHA encryption - all in a 176-pin LFBGA package with –40°C to +85°C operation.
Technical Context
The R5F526TFDGFP#30 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dual DMA controllers (DMAC: 8 channels; EXDMAC: 2 channels) and a dedicated EDMAC (3 channels) for Ethernet offload, reducing CPU load during high-throughput frame processing.
Its clock system supports independent domain scaling: ICLK up to 120 MHz for CPU execution, PCLKA up to 120 MHz for Ethernet/USB/AES, and PCLKB up to 60 MHz for timers/ADC/DAC. The device includes a memory protection unit (MPU), SEC-DED ECC on 32 KB RAM, and hardware-assisted IEC 60730 safety functions including oscillation-stop detection and A/D self-diagnostic.
