For engineers reviewing the R7FA6E2B93CNH#BA0 datasheet, R7FA6E2B93CNH#BA0 pinout, R7FA6E2B93CNH#BA0 application, or R7FA6E2B93CNH#BA0 equivalent, key selection criteria include its 32-pin QFN package, -40°C to +105°C temperature grade, TrustZone-enabled security, 16 GPIO pins with 4× 5-V tolerant inputs, and integrated ADC12/DAC12 for sensor signal conditioning.

Technical Context

The R7FA6E2B93CNH#BA0 implements Armv8-M architecture with TrustZone, supporting secure/non-secure execution states, MPU partitioning (8 regions each), and dual SysTick timers. Its clock system integrates HOCO/MOCO/LOCO oscillators, PLL, and CAC for frequency accuracy monitoring.

Peripheral interconnect uses Event Link Controller (ELC) for CPU-free module triggering, Data Transfer Controller (DTC), and 8-channel DMAC for zero-CPU data movement. The 32-pin QFN variant retains full GPT16E×4, AGT×2, RTC, USBFS, CANFD, and SSIE functionality while reducing I/O count to 16 pins.

FAQ

What is the maximum operating frequency of the R7FA6E2B93CNH#BA0?

The R7FA6E2B93CNH#BA0 operates at a maximum CPU frequency of 200 MHz using its Arm Cortex-M33 core. This speed is achievable when powered within the 2.7–3.6 V range and using the PLL with an appropriate clock source such as the 8–24 MHz main oscillator (MOSC). The device maintains this performance across its full -40°C to +105°C operating temperature range, making it suitable for demanding industrial environments where thermal stability is critical. The R7FA6E2B93CNH#BA0 achieves this performance while retaining low-power modes and peripheral responsiveness.

Does the R7FA6E2B93CNH#BA0 support CAN FD communication?

Yes, the R7FA6E2B93CNH#BA0 integrates a CAN with Flexible Data-Rate (CANFD) module compliant with ISO 11898-1. It supports both classical CAN frames and CAN FD frames, with 4 transmit buffers and 32 receive buffers. The module operates at bit rates up to 5 Mbps in the data phase and includes built-in message filtering and error handling. This capability is retained in the 32-pin QFN package, enabling compact, high-speed industrial fieldbus connectivity without external CAN controllers or transceivers - only a standard CAN transceiver (e.g., TJA1042) is required on the board.

What analog peripherals are included in the R7FA6E2B93CNH#BA0?

The R7FA6E2B93CNH#BA0 includes a 12-bit successive approximation ADC12 with up to 4 selectable analog input channels (AN00–AN03), two 12-bit DAC12 outputs (DA0, DA1), and an on-die temperature sensor (TSN). The ADC12 supports external trigger inputs (ADTRG0) and internal references (VREFH0/VREFL0), while the DAC12 outputs are buffered and can drive precision loads. The TSN provides a voltage output linearly proportional to die temperature, digitized by the ADC12 for thermal monitoring. These peripherals are fully functional in the 32-pin QFN package and require no external components for basic operation.

How does the R7FA6E2B93CNH#BA0 implement hardware security?

The R7FA6E2B93CNH#BA0 implements hardware security via Arm TrustZone for Armv8-M, providing secure and non-secure memory and peripheral attribution. It includes a secure MPU with 8 regions, 128-bit unique ID, True Random Number Generator (TRNG), and secure pin multiplexing. Secure boot is enforced through immutable ROM bootloader that validates firmware signatures before execution. These features are active in the R7FA6E2B93CNH#BA0 without requiring external security elements, enabling secure firmware updates, cryptographic key protection, and tamper-resistant operation in industrial deployments.

What debug interface does the R7FA6E2B93CNH#BA0 use?

The R7FA6E2B93CNH#BA0 uses Serial Wire Debug (SWD) with two dedicated pins: SWDIO (bidirectional data) and SWCLK (clock input). This 2-pin interface supports full programming, real-time debugging, and trace capabilities via standard tools including Renesas E2 studio, SEGGER J-Link, and CMSIS-DAP debug probes. SWD is enabled by default after reset and remains accessible even in low-power modes when configured. No additional debug hardware or pin multiplexing is required - the interface is native and does not conflict with other peripheral functions on the R7FA6E2B93CNH#BA0's 32-pin QFN package.
