Renesas R7FA6E10D2CFP#HA0

Overview

R7FA6E10D2CFP from Renesas is a 32-bit Arm Cortex-M33 microcontroller operating at up to 200 MHz, featuring 512 KB code flash, 8 KB data flash, and 256 KB SRAM with parity. It integrates Ethernet MAC (RMII), USB 2.0 Full-Speed, SDHI, QSPI, CAN, dual I²C, six SCI, two SPI, SSIE, 12-bit ADC (11 channels), 12-bit DAC, and TrustZone security - deployed in industrial gateways requiring real-time connectivity and secure firmware updates.

For engineers reviewing the R7FA6E10D2CFP datasheet, R7FA6E10D2CFP pinout, R7FA6E10D2CFP application, or R7FA6E10D2CFP equivalent, key selection criteria include its 100-pin LQFP package, -40°C to +85°C industrial temperature range, dual-bank flash for safe OTA updates, RMII Ethernet interface, and hardware-accelerated cryptographic support via SCE9 subsystem.

Technical Context

The R7FA6E10D2CFP implements Armv8-M with TrustZone, enabling secure/non-secure execution states, MPU partitioning (8 regions each), and secure boot enforcement. Its system architecture includes ETHERC/EDMAC co-processing for zero-CPU packet handling and DTC/DMAC (8-channel) offloading for sensor-to-cloud data pipelines.

Timing is managed by dual PLLs, HOCO/MOCO/LOCO oscillators, and CAC for clock accuracy validation. Power management supports Deep Software Standby with RTC, AGT timers, and VBATT backup - critical for battery-backed edge nodes maintaining timekeeping and wake-on-event capability.

FAQ

What is the maximum operating frequency of the R7FA6E10D2CFP?

The R7FA6E10D2CFP operates at a maximum frequency of 200 MHz using its Arm Cortex-M33 core. This speed is achievable with the on-chip PLL driven by the main clock oscillator (8–24 MHz) or high-speed on-chip oscillator (HOCO). The R7FA6E10D2CFP maintains full peripheral functionality-including Ethernet MAC, USBFS, and QSPI-at this clock rate, as confirmed in the R01DS0392EJ0140 datasheet Rev.1.40.

Does the R7FA6E10D2CFP support Ethernet connectivity, and what interface does it use?

Yes, the R7FA6E10D2CFP includes an integrated Ethernet MAC (ETHERC) compliant with IEEE 802.3, supporting 10/100 Mbps operation exclusively in RMII mode. It requires an external PHY (e.g., LAN8720A) connected via RMII0_TXD0/1, RMII0_RXD0/1, REF50CK0, and control signals. The R7FA6E10D2CFP does not support MII or GMII, and no external MAC logic is needed - the ETHERC links directly to the EDMAC for zero-CPU packet handling.

What security features are implemented in the R7FA6E10D2CFP?

The R7FA6E10D2CFP implements Arm TrustZone for hardware-enforced secure/non-secure world separation, MPU_S/MPU_NS (8 regions each), and the SCE9 security subsystem - which includes access control, true random number generation (TRNG), and a unique chip ID. While full SCE9 cryptographic acceleration (AES/SHA) is documented for the RA6E1 family, the R7FA6E10D2CFP specifically supports these functions per datasheet Section 1.1 and Table 1.13. No software-only fallbacks are required for basic secure boot or key provisioning.

How much flash memory does the R7FA6E10D2CFP have, and is it dual-bank?

The R7FA6E10D2CFP contains 512 KB of on-chip code flash memory organized in dual-bank configuration, plus 8 KB of data flash. Dual-bank operation enables background programming and SWAP functionality - allowing one bank to execute code while the other is erased/programmed, then atomically switching banks via software command. This architecture is explicitly confirmed for R7FA6E10D2CFP in Table 1.12 and Section 1.4 of the R01DS0392EJ0140 datasheet.

Which package type does the R7FA6E10D2CFP use, and how many I/O pins are available?

The R7FA6E10D2CFP uses a 100-pin LQFP package (PLQP0100KB-B, 14 mm × 14 mm, 0.5 mm pitch) with 75 general-purpose I/O pins, 14 of which are 5-V tolerant. It also provides 76 pull-up resistors, 75 N-channel open-drain outputs, and dedicated pins for Ethernet RMII, USB, QSPI, and analog functions. Pin assignments match Figure 1.3 in the R01DS0392EJ0140 datasheet, confirming full compatibility with RA6E1 reference designs.
