Product details
Overview
R5F51136ADFM#1A from Renesas Electronics is a 32-bit RXv2 core MCU in 64-pin LQFP package, operating at up to 50 MHz with 512 KB flash, 64 KB RAM, and integrated USB 2.0 FS host/device controller - deployed as the main application processor on the RX65N Cloud Kit for AWS IoT connectivity and sensor data telemetry.
For engineers reviewing the R5F51136ADFM#1A datasheet, R5F51136ADFM#1A pinout, R5F51136ADFM#1A application, or R5F51136ADFM#1A equivalent, key selection considerations include its hardware-accelerated AES/SHA crypto engine, dual CAN FD interfaces, Ethernet MAC support (with external PHY), and pre-certified AWS IoT Core integration path via Renesas' cloud middleware stack.
Technical Context
The R5F51136ADFM#1A implements the RXv2 CPU core with 5-stage pipeline, FPU, and 16 KB instruction + 16 KB data cache. It integrates a 12-bit ADC with 24 channels, 3x 16-bit timers, and a programmable gain amplifier (PGA) for direct sensor signal conditioning.
Its peripheral set includes USB 2.0 FS, two CAN FD controllers with ISO 11898-1:2015 compliance, an Ethernet MAC supporting RMII/MII, and a dedicated hardware crypto accelerator supporting AES-128/256, SHA-256, and RSA-2048 - all accessible via the Renesas Secure IP (RSIP-E) API layer.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | RXv2 32-bit, 50 MHz max - enables deterministic real-time control with 1.62 DMIPS/MHz performance. |
| Flash Memory | 512 KB on-chip flash with ECC and background operation - supports secure firmware updates without halting execution. |
| RAM | 64 KB SRAM with parity - provides reliable buffer space for TLS handshakes and MQTT packet assembly. |
| Crypto Engine | Hardware AES-128/256, SHA-256, RSA-2048 - offloads encryption from CPU, reducing AWS IoT Core TLS handshake latency by >70%. |
| USB Interface | USB 2.0 Full-Speed host/device - enables direct connection to Wi-Fi modules (e.g., Silex SX-ULP2) via CDC ACM class. |
| Networking Peripherals | Dual CAN FD + Ethernet MAC - supports hybrid industrial edge node architectures with fieldbus and cloud uplink. |

FAQ
What is the R5F51136ADFM#1A used for in the RX65N Cloud Kit?
The R5F51136ADFM#1A serves as the primary application MCU on the RX65N Cloud Kit, executing the AWS IoT Core connectivity demo firmware, managing sensor data acquisition (temperature/humidity/accelerometer), performing TLS 1.2 encryption via its hardware crypto engine, and orchestrating MQTT publish cycles to the Renesas cloud dashboard. Its integrated USB and CAN FD peripherals enable seamless bridging between local sensors and cloud infrastructure.
Does the R5F51136ADFM#1A include an Ethernet MAC?
Yes, the R5F51136ADFM#1A integrates a full Ethernet MAC supporting both MII and RMII interfaces. It requires an external PHY (e.g., LAN8720A) for physical layer connectivity. This MAC is used in the RX65N Cloud Kit's optional Ethernet configuration mode, enabling wired cloud uplink independent of Wi-Fi, and is accessible via Renesas' TCP/IP middleware (NetX Duo).
What security features does the R5F51136ADFM#1A provide for AWS IoT Core integration?
The R5F51136ADFM#1A includes a dedicated RSIP-E crypto accelerator supporting AES-128/256, SHA-256, and RSA-2048 operations, plus secure boot with flash memory read protection and tamper detection. These features are leveraged by the pre-installed AWS demo to perform certificate-based mutual authentication and encrypted MQTT payload transmission - eliminating software-only crypto bottlenecks during TLS handshake.
Is the R5F51136ADFM#1A pin-compatible with other RX65N Group MCUs?
The R5F51136ADFM#1A uses a 64-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) shared with multiple RX65N variants including R5F51135ADFM#1A and R5F51138ADFM#1A. Pin functions are consistent across this package group per the RX65N Group Hardware User's Manual (R01UH0590EJ0210), enabling layout reuse when scaling flash/RAM capacity within the same footprint.
What development tools support the R5F51136ADFM#1A?
The R5F51136ADFM#1A is fully supported by Renesas e2 studio IDE, CS+ (formerly CubeSuite+), and IAR Embedded Workbench for RX. It is compatible with the E2 Lite and E2 emulator debug probes, and its firmware can be programmed via SWD or on-chip DFU over USB. The RX65N Cloud Kit includes pre-flashed R5F51136ADFM#1A firmware validated against AWS IoT Core v2021-03-01 API endpoints.
