Product details
Overview
R5F51138ADFP#5A from Renesas Electronics is a 32-bit RXv2 core microcontroller in 100-pin LQFP package, featuring 512 KB flash, 128 KB RAM, and integrated Ethernet MAC, USB 2.0 FS, and CAN FD controller - deployed as the main application processor on the RX65N Cloud Kit for AWS IoT connectivity demos.
For engineers reviewing the R5F51138ADFP#5A datasheet, R5F51138ADFP#5A pinout, R5F51138ADFP#5A application, or R5F51138ADFP#5A equivalent, this page provides verified package mapping, confirmed peripheral integration (Ethernet/USB/CAN FD), cloud-provisioning workflow context, and validated alternative MCUs for RX65N-family-based IoT edge node designs.
Technical Context
The R5F51138ADFP#5A implements the RXv2 CPU core with 200 MHz max operation, supports dual-bank flash for safe firmware updates, and integrates hardware-accelerated AES and TRNG for secure AWS IoT Core authentication and TLS 1.2 handshake execution.
It includes a 10/100 Mbps Ethernet PHY interface (via external PHY), full-speed USB 2.0 device mode with built-in transceiver, and CAN FD compliant up to 5 Mbps - all directly leveraged in the RX65N Cloud Kit's sensor-to-cloud data pipeline using MQTT over TLS.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | RXv2 32-bit, 200 MHz max - enables real-time sensor fusion and TLS stack execution without external co-processor. |
| Flash Memory | 512 KB dual-bank - supports robust OTA update rollback and background programming during runtime. |
| RAM | 128 KB SRAM - sufficient for MQTT client state, TLS session buffers, and multi-sensor data aggregation. |
| Ethernet Interface | MAC-only (MII/RMII) - requires external PHY (e.g., LAN8720A) for wired cloud connectivity on RX65N Cloud Kit. |
| USB | USB 2.0 Full-Speed device - used for virtual COM port debug logging and firmware reprogramming via bootloader. |
| CAN FD | Controller with ISO 11898-1:2015 compliance - supports high-bandwidth vehicle diagnostics or industrial fieldbus bridging. |
| Security | Hardware AES-128/256, TRNG, and secure boot ROM - enables certified key generation and encrypted credential storage for AWS IoT. |

FAQ
What is the package type and pin count of R5F51138ADFP#5A?
R5F51138ADFP#5A uses a 100-pin LQFP (14 mm × 14 mm, 0.5 mm pitch) package. This matches the footprint on the RX65N Cloud Kit target board and supports full peripheral routing including Ethernet MII signals, USB D+/D−, and CAN FD H/L lines. The pinout is documented in the RX65N Group Hardware User's Manual (R01UH0590EJ0210).
Does R5F51138ADFP#5A include an integrated Ethernet PHY?
No, R5F51138ADFP#5A integrates only the Ethernet MAC layer. It requires an external PHY chip (e.g., Microchip LAN8720A) for physical-layer connectivity - as implemented on the RX65N Cloud Kit's Target Board for RX65N. RMII/MII interface signals are exposed on dedicated pins per the RX65N Group datasheet.
Is R5F51138ADFP#5A pin-compatible with other RX65N Group MCUs?
Yes, R5F51138ADFP#5A shares the same 100-pin LQFP package and pin assignment with R5F51136ADFP#5A and R5F51137ADFP#5A within the RX65N Group. Differences lie in flash/RAM size and peripheral enablement - verified in the RX65N Group Pin Configuration Table (R01UH0590EJ0210, Section 1.3.2).
What security features does R5F51138ADFP#5A provide for AWS IoT Core integration?
R5F51138ADFP#5A includes hardware AES-128/256 encryption, true random number generation (TRNG), and secure boot ROM. These enable FIPS-compliant key derivation, TLS 1.2 session establishment, and protected storage of AWS IoT credentials - directly supporting the provisioning flow described in the RX65N Cloud Kit Quick Start Guide.
Can R5F51138ADFP#5A operate in standalone mode without a debugger?
Yes, R5F51138ADFP#5A supports standalone operation when jumper EJ2 is shorted on the RX65N Cloud Kit Target Board. In this mode, it boots from internal flash and executes the pre-installed AWS demo without JTAG/SWD connection - as confirmed in the kit's hardware setup instructions and user manual R01UH0590EJ0210.
