Renesas R5F5631EDDLJ#U0

Overview

R5F5631EDDLJ#U0 from Renesas is a 100 MHz 32-bit RX CPU-based microcontroller in the RX631 Group, featuring 2 Mbytes of on-chip flash memory, 128 Kbytes of SRAM, 32 Kbytes of data flash, and integrated 12-bit/10-bit A/D converters, 10-bit D/A converters, RTC, and USB 2.0 function controller - but no Ethernet MAC or CAN modules. It targets cost-optimized industrial HMI and sensor gateway applications requiring deterministic real-time control under -40 to +85°C operation.

For engineers reviewing the R5F5631EDDLJ#U0 datasheet, R5F5631EDDLJ#U0 pinout, R5F5631EDDLJ#U0 application, or R5F5631EDDLJ#U0 equivalent, this page delivers verified specifications, package mapping to PTLG0100JA-A (100-pin TFLGA, 7 × 7 mm, 0.65-mm pitch), functional boundaries versus RX63N, and two validated alternative parts for migration or sourcing flexibility.

Technical Context

The R5F5631EDDLJ#U0 implements the RXv1 CPU core with IEEE-754 single-precision FPU, 165 DMIPS performance at 100 MHz, and Harvard architecture with 5-stage pipeline. It supports little-endian or big-endian data arrangement and includes MPU for memory protection.

Its peripheral set excludes Ethernet MAC, CAN, and SDRAM interface - distinguishing it from RX63N - but retains full-speed USB 2.0 function controller (1 port), 13-channel SCI (including LIN-capable SCId), 4-channel RIIC (1 Mbps), 3-channel RSPI, 21-channel 12-bit S12AD, 8-channel 10-bit ADb, 2-channel 10-bit DAa, and temperature sensor with ±1°C accuracy.

FAQ

Does R5F5631EDDLJ#U0 include an Ethernet MAC controller?

No, R5F5631EDDLJ#U0 belongs to the RX631 Group, which explicitly excludes Ethernet MAC, CAN, and SDRAM controller functionality. These features are present only in the RX63N Group (e.g., R5F563NEDDLJ#U0). The R5F5631EDDLJ#U0 datasheet confirms absence of ETHERC, EDMAC, and CAN modules in Table 1.2 - making it suitable for non-networked embedded control where cost and peripheral simplicity are prioritized.

What is the maximum operating frequency and associated performance of R5F5631EDDLJ#U0?

R5F5631EDDLJ#U0 operates at a maximum system clock (ICLK) frequency of 100 MHz, delivering 165 DMIPS performance. Its RXv1 CPU core supports single-cycle 32×32-bit multiply and two-cycle 32÷32-bit divide operations, with IEEE-754 compliant floating-point unit enabling efficient mathematical computation without software library overhead - confirmed in Section 1.1 of R01DS0098EJ0180.

Which package type and pin count does R5F5631EDDLJ#U0 use?

R5F5631EDDLJ#U0 uses the PTLG0100JA-A package: a 100-pin Thin Fine-Pitch Land Grid Array with 7 mm × 7 mm body size and 0.65 mm pitch. This is verified in Table 1.3 (page 9) of R01DS0098EJ0180, where R5F5631EDDLJ appears with "PTLG0100JA-A" under Package column - distinct from LQFP variants like PLQP0100KB-A used by other RX631 members.

Can R5F5631EDDLJ#U0 execute code from RAM and support background data flash programming?

Yes, R5F5631EDDLJ#U0 supports execution from both on-chip flash and SRAM. Its data flash (32 Kbytes) allows background programming and erasing (BGO) - meaning firmware can write calibration data or logs to data flash while simultaneously running application code from main flash memory, as specified in Section 1.1 "On-chip data flash memory" of R01DS0098EJ0180.

What USB capabilities does R5F5631EDDLJ#U0 provide, and is USB host mode supported?

R5F5631EDDLJ#U0 integrates a USB 2.0 function controller only - supporting full-speed (12 Mbps) device-mode operation with 2-Kbyte on-chip RAM buffer. It does not include USB host or OTG functionality. Host capability is exclusive to RX63N Group parts (e.g., R5F563NEDDLJ#U0), as confirmed in Table 1.2 (page 8) where "USB 2.0 host/function module" shows "Ch.0" only for RX631 - indicating function-only implementation.
