Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance secure MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7FA6M5BH3CFB#AA0 | Arm Cortex-M33 @ 200 MHz, 1 MB flash, no Ethernet MAC or CAN FD, RSIP-E50A (no ECC support) | Lacks Ethernet and CAN FD; suitable for cost-sensitive motor control without network bridging | Select when Ethernet/CAN FD integration is unnecessary and BOM cost reduction outweighs performance/security trade-offs |
| R7FA8M5BH3CFB#AA0 | Arm Cortex-M85 @ 480 MHz, same security IP and peripherals, but 1 MB code flash and 144-pin LQFP package | Lower memory density and reduced I/O count (106 vs. 128); no SDRAM interface support | Choose for space-constrained designs where 2 MB flash and 176-pin I/O scalability are not required |
Compared with R7FA8T1AHECFC#UA0, the R7FA6M5BH3CFB#AA0 sacrifices 2.4× CPU performance, Ethernet, and CAN FD for lower cost and power, while the R7FA8M5BH3CFB#AA0 retains identical core and security features but reduces flash capacity and I/O count - making it viable only where full RA8T1 feature set is over-specified.
