For engineers reviewing the R7FA6E10D2CFM#AA5 datasheet, R7FA6E10D2CFM#AA5 pinout, R7FA6E10D2CFM#AA5 application, or R7FA6E10D2CFM#AA5 equivalent, this page delivers verified specifications, package mapping, validated pin functions, security architecture details, and direct alternative part comparisons for embedded system design and BOM optimization.

Technical Context

The R7FA6E10D2CFM#AA5 implements Arm TrustZone for hardware-enforced secure/non-secure execution isolation, with MPU_S and MPU_NS each supporting eight memory regions. Its dual-bank flash supports background operation and SWAP firmware updates without CPU interruption.

It integrates ETHERC/EDMAC for RMII-mode Ethernet with zero-CPU packet handling, USBFS with internal transceiver and 10-pipe endpoint support, and a full CAN 2.0A/B controller requiring external transceiver. The 6-channel AGT timers operate asynchronously from low-power clocks, enabling precise wake-up timing during deep standby.

FAQ

What is the maximum operating frequency of the R7FA6E10D2CFM#AA5?

The R7FA6E10D2CFM#AA5 operates at a maximum frequency of 200 MHz using its Arm Cortex-M33 core. This speed is achieved with the PLL clock source and is fully supported across the specified operating voltage range (2.7–3.6 V) and temperature range (−40°C to +85°C). All peripherals, including Ethernet MAC and USBFS, are functional at this clock rate, and the datasheet confirms timing compliance up to 200 MHz in all relevant sections.

Does the R7FA6E10D2CFM#AA5 include an integrated Ethernet PHY?

No, the R7FA6E10D2CFM#AA5 includes only the Ethernet MAC (ETHERC) and DMA controller (EDMAC), not a physical layer transceiver. It supports RMII interface and requires an external PHY chip (e.g., LAN8720A or DP83848) connected via RMII0_TXD0/1, RMII0_RXD0/1, REF50CK0, and associated control signals. The R7FA6E10D2CFM#AA5 does not provide MII or SMI management interfaces beyond MDIO/MDC.

What package type and pin count does the R7FA6E10D2CFM#AA5 use?

The R7FA6E10D2CFM#AA5 uses a 64-pin LQFP package (PLQP0064KB-C), measuring 10 mm × 10 mm with 0.5 mm pitch. This matches the "FM" suffix in the part number and is confirmed in Table 1.12 and Figure 1.4 of the R01DS0392EJ0140 datasheet. It provides 41 general-purpose I/O pins, 9 of which are 5-V tolerant, and dedicated pins for USB, CAN, QSPI, and SDHI interfaces.

Is TrustZone security fully implemented on the R7FA6E10D2CFM#AA5?

Yes, the R7FA6E10D2CFM#AA5 implements Arm TrustZone with secure/non-secure memory attribution for code flash (up to six regions), data flash (two regions), and SRAM (three regions), plus individual secure/non-secure assignment for each peripheral. However, only the access control circuit, RNG, and unique ID within the SCE9 security module are guaranteed functional; other SCE9 blocks (e.g., AES accelerator) are not supported per datasheet Note 1 and Figure 1.1.

What are the supported clock sources for the R7FA6E10D2CFM#AA5?

The R7FA6E10D2CFM#AA5 supports multiple clock sources: main oscillator (8–24 MHz crystal on XTAL/EXTAL), sub-clock oscillator (32.768 kHz on XCIN/XCOUT), and on-chip oscillators - HOCO (16/18/20 MHz), MOCO (8 MHz), LOCO (32.768 kHz), and IWDT-dedicated (15 kHz). PLL and PLL2 generate high-frequency system clocks, and CAC provides clock accuracy measurement against any selected source.
