R5F5631WDGFC#V0

Microcontrollers Overview

The R5F5631WDGFC#V0 is a 32-bit microcontroller from the Renesas RX631 group, utilizing the RX CPU core. It features up to 2 MB of on-chip flash memory and 256 KB of SRAM. The device operates at a maximum frequency of 100 MHz and includes an integrated floating-point unit (FPU). It supports a supply voltage range of 2.7 V to 3.6 V and is housed in a 176-pin LQFP package.

Microcontrollers Feature Summary

• Integrates a high-performance 32-bit RX CPU core with single-precision IEEE-754 floating-point capabilities for efficient digital signal processing.
• Provides extensive connectivity options including Ethernet MAC, full-speed USB 2.0 interfaces, CAN, I2C, SCI, and SPI modules.
• Features multiple analog-to-digital converters with selectable 10-bit and 12-bit resolutions alongside a real-time clock.

Microcontrollers Applications

• Industrial automation controllers requiring robust communication protocols
• Smart metering systems utilizing Ethernet or USB connectivity
• Medical equipment needing precise analog signal acquisition

Microcontrollers Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm pinout and feature variations. Confirm current lifecycle status as some RX631 variants are marked as not recommended for new designs. Ensure compatibility with required operating temperature ranges and moisture sensitivity levels before integration.

Microcontrollers Selection Notes

Select this component when Ethernet connectivity and high-speed USB are required within the RX631 family. Compare against the RX63N group if additional security features or different peripheral configurations are needed. Evaluate memory requirements against the available 2 MB flash and 256 KB RAM limits.

Microcontrollers Part Context

This part belongs to the RX631 group, which distinguishes itself from the RX63N group by lacking an integrated Ethernet controller. It shares the same core architecture and performance metrics but offers a different peripheral set tailored for applications where Ethernet is not essential.

Microcontrollers Replacement Considerations

Consult the RX Family Part Number Guide for verified substitutes. Direct replacements may include other RX631 variants with differing memory sizes or packages. Verify that any alternative maintains the 176-pin LQFP form factor and compatible electrical specifications.
