Overview
R7FA6M2AF2CLK#AC0 from Renesas is a 120-MHz Arm Cortex-M4 microcontroller with FPU, 1-MB code flash, 384-KB SRAM, Ethernet MAC, dual CAN, USB 2.0 Full-Speed, SDHI ×2, QSPI, CTSU, and SCE7 crypto engine - designed for industrial gateways, networked HMI, and secure edge controllers operating at -40°C to +85°C.
For engineers reviewing the R7FA6M2AF2CLK#AC0 datasheet, R7FA6M2AF2CLK#AC0 pinout, R7FA6M2AF2CLK#AC0 application, or R7FA6M2AF2CLK#AC0 equivalent, key selection considerations include its 145-pin LGA package, dual CAN 2.0B support, hardware-accelerated AES/SHA/RSA, 12-bit ADC ×2 with 20-channel analog input, and integrated Ethernet MAC with EDMAC DMA coupling.
Technical Context
The R7FA6M2AF2CLK#AC0 implements an Armv7E-M core with DSP extensions and single-precision FPU, executing at up to 120 MHz with 4-GB address space and Arm MPU supporting eight memory protection regions. It integrates boundary scan and on-chip debugging via JTAG, SWD, and ETM.
Its system architecture includes dual 32-bit GPT timer groups (GPT32EH ×4, GPT32E ×4), AGT ×2 for low-power timing, RTC with calendar mode and VBATT backup, and ELC for CPU-free peripheral event chaining - enabling deterministic real-time response in safety-aware applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7FA6M2AF3CLK#AC0 | Identical feature set but rated for -40°C to +105°C industrial temp range; same 145-pin LGA package. | Required for extended-temperature deployments (e.g., outdoor base stations, motor drives). | Select when ambient operating temperature exceeds +85°C; no firmware or layout changes needed. |
| R7FA6M2AF3CFB#AA0 | 144-pin LQFP package, same 1-MB flash/SRAM/crypto/peripherals; lacks SDRAM interface and one GPT32 channel. | Better suited for cost-sensitive, non-SDRAM applications where LQFP reflow compatibility is preferred. | Choose for simplified assembly and lower PCB layer count - verify GPT32 count (5 vs. 6) and external bus requirements match design. |
