Product details
Overview
R5F5631ACDLJ#U0 from Renesas is a 100 MHz 32-bit RX CPU core microcontroller in the RX631 Group, featuring 768 KB on-chip flash memory, 128 KB SRAM, 32 KB data flash, IEEE-754 single-precision FPU, and integrated 12-bit/10-bit A/D converters - designed for industrial control and networked embedded systems without Ethernet MAC.
For engineers reviewing the R5F5631ACDLJ#U0 datasheet, R5F5631ACDLJ#U0 pinout, R5F5631ACDLJ#U0 application, or R5F5631ACDLJ#U0 equivalent, key selection criteria include its 100 MHz operation, absence of Ethernet controller (distinguishing it from RX63N), 100-pin TFLGA package, -40 to +85°C temperature range, and support for USB 2.0 host/function, CAN, multiple SCI, I²C, and SPI interfaces.
Technical Context
The R5F5631ACDLJ#U0 implements the CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and memory protection unit (MPU). It executes at 165 DMIPS and supports little-endian or big-endian data arrangement, with on-chip 32×32→64-bit multiplier and 32/32→32-bit divider.
Its clock system includes main crystal oscillator, subclock, 125-kHz LOCO, 50-MHz HOCO, and PLL frequency synthesizer - enabling independent division/multiplication for ICLK (up to 100 MHz), PCLK (up to 50 MHz), FCLK (up to 50 MHz), and BCLK (up to 50 MHz). The device lacks Ethernet MAC and SDRAM controller, consistent with RX631 Group specification.
