Renesas R5F5630DDDFC#V0

Overview

R5F5630DDDFC#V0 from Renesas is a 100-MHz 32-bit RX CPU-based microcontroller with single-precision IEEE-754 FPU, 1.5-Mbyte on-chip flash, 128-Kbyte SRAM, USB 2.0 full-speed interface, CAN v2.0B (3 channels), and 21-channel 12-bit A/D converter. It operates from a 2.7–3.6-V supply at –40 to +85°C and targets industrial motor control, PLC I/O modules, and embedded HMI systems requiring deterministic real-time performance.

For engineers reviewing the R5F5630DDDFC#V0 datasheet, R5F5630DDDFC#V0 pinout, R5F5630DDDFC#V0 application, or R5F5630DDDFC#V0 equivalent, key selection criteria include its 176-pin LQFP (PLQP0176KB-A) package, 100-MHz timing-critical peripheral clocking (ICLK/PCLK up to 100/50 MHz), integrated MPU for functional safety, and IEC60730-compliant self-test features including CRC, IWDT, and A/D diagnostic support.

Technical Context

The R5F5630DDDFC#V0 implements a CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and memory protection unit (MPU) - enabling deterministic interrupt latency and secure partitioning for safety-critical firmware. Its dual-clock domain supports independent system (ICLK), peripheral (PCLK), FlashIF (FCLK), and external bus (BCLK) clocks, each configurable up to 100/50/50/50 MHz respectively.

It integrates three communication subsystems optimized for industrial protocols: USB 2.0 full-speed (12 Mbps) with 2-Kbyte on-chip buffer, CAN (ISO11898-1 compliant, 32 mailboxes/channel × 3 channels), and RSPI (3 channels, up to 32-bit transfers with double-buffered 128-bit FIFOs). The MTU2 and TPU timer units provide hardware-accelerated PWM generation, phase counting, and A/D trigger synchronization for motor control loops.
