Equivalent & Alternatives
The following parts are listed as comparable options for similar Arm Cortex-M33 microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7FA6M4AF3CFP#BA5 | 1 MB code flash (vs. 512 KB), same package/peripherals/temperature grade | Better suited for complex protocol stacks (e.g., full TCP/IP + TLS + OTA) requiring larger firmware footprint | Select when firmware size exceeds 512 KB or future-proofing for feature expansion is critical |
| R7FA6M4AD3CBM#AA5 | 144-pin BGA package (vs. 100-pin LQFP), identical memory/peripherals/temperature | Higher I/O count (109 vs. 75) and smaller footprint (7 mm × 7 mm) for space-constrained designs | Select when board area is constrained and additional GPIOs or RMII+USB+CAN concurrency is needed |
Compared with R7FA6M4AD3CFP#BA5, the AF3CFP variant offers double flash capacity for richer firmware but same pinout and thermal envelope, while the AD3CBM variant trades package size and I/O count for PCB area reduction - neither is pin-compatible, requiring layout revision.

FAQ
What is the maximum operating frequency of the R7FA6M4AD3CFP#BA5?
The R7FA6M4AD3CFP#BA5 operates at a maximum frequency of 200 MHz using its Arm Cortex-M33 core. This speed is achieved with the on-chip PLL driven by the main clock oscillator (8–24 MHz crystal) or high-speed on-chip oscillator (HOCO). The core maintains full performance across its -40°C to +105°C operating range, with voltage regulation maintained between 2.7 V and 3.6 V.
Does the R7FA6M4AD3CFP#BA5 include an integrated Ethernet PHY?
No, the R7FA6M4AD3CFP#BA5 includes only an Ethernet MAC/DMA controller compliant with IEEE 802.3, not a physical layer transceiver. It supports RMII interface with an external PHY such as the LAN8720A or DP83848. The RMII signals (TXD0/1, RXD0/1, CRS_DV, REF_CLK) are routed to dedicated pins and require precise 50 MHz clock tolerance and impedance-controlled PCB routing.
How does the dual-bank flash architecture benefit firmware updates on the R7FA6M4AD3CFP#BA5?
The R7FA6M4AD3CFP#BA5's dual-bank flash enables background programming and atomic SWAP operations. While the active bank executes firmware, the inactive bank receives a new image via UART, USB, or Ethernet. Upon verification, the SWAP command instantly redirects execution to the updated bank - eliminating reboot delays and ensuring zero-downtime updates essential for unattended industrial systems.
What security features are implemented in hardware on the R7FA6M4AD3CFP#BA5?
The R7FA6M4AD3CFP#BA5 integrates Secure Crypto Engine 9 (SCE9) with hardware accelerators for AES-128/256, RSA-2048/4096, ECC, and SHA224/256. It also includes Arm TrustZone for memory/peripheral isolation, tamper detection pins, secure key injection, and 128-bit unique device ID. These features collectively enable secure boot, encrypted firmware storage, and TLS offload without software-only cryptography overhead.
Can the R7FA6M4AD3CFP#BA5 support capacitive touch sensing without external components?
Yes, the R7FA6M4AD3CFP#BA5 includes a dedicated Capacitive Touch Sensing Unit (CTSU) that performs self-capacitance and mutual-capacitance measurements using internal current sources and sigma-delta ADCs. It supports up to 20 touch channels on the 100-pin variant and requires only PCB electrodes and optional shielding - no external IC or RC networks are needed for basic button/slider implementation.
