Renesas R7FA6E2BB3CBB#BC0

Overview

R7FA6E2BB3CBB#BC0 from Renesas is a 32-bit Arm® Cortex®-M33 microcontroller operating at up to 200 MHz, featuring 256 KB code flash, 4 KB data flash, and 40 KB SRAM. It integrates USB Full-Speed, CAN FD, Quad SPI, I3C, dual 12-bit DACs, 12-bit ADC with temperature sensor, and TrustZone-based security-designed for industrial control, motor drive, and secure IoT edge nodes.

For engineers reviewing the R7FA6E2BB3CBB#BC0 datasheet, R7FA6E2BB3CBB#BC0 pinout, R7FA6E2BB3CBB#BC0 application, or R7FA6E2BB3CBB#BC0 equivalent, key selection criteria include its BGA-36 package with 20 I/O pins, -40°C to +105°C operation, 2.7–3.6 V supply, and support for secure boot, real-time motor control via GPT16E × 6, and low-power AGT timers.

Technical Context

The R7FA6E2BB3CBB#BC0 implements Armv8-M architecture with TrustZone, enabling hardware-isolated secure and non-secure execution states. Its memory protection unit (MPU_S/MPU_NS) enforces 8-region access control per domain, while the Event Link Controller (ELC) enables CPU-free peripheral chaining-critical for deterministic motor timing and USB/CANFD coexistence.

It supports dual-clock domain operation: system clock derived from PLL (up to 200 MHz) and independent low-power clocks (LOCO, SOSC) for RTC and AGT timers. The integrated USBFS module includes an on-chip transceiver and 5-pipe endpoint buffer, and CANFD supports ISO 11898-1 frames with 4 TX/32 RX buffers-both accessible in secure or non-secure contexts via configurable peripheral attribution.

FAQ

What is the maximum operating frequency of the R7FA6E2BB3CBB#BC0?

The R7FA6E2BB3CBB#BC0 operates at a maximum CPU frequency of 200 MHz using its Arm Cortex-M33 core. This speed is achieved via the on-chip PLL driven by the main clock oscillator (MOSC) or high-speed on-chip oscillator (HOCO). Frequency stability is maintained across the full -40°C to +105°C range, and the Clock Frequency Accuracy Measurement Circuit (CAC) allows runtime validation of clock integrity. The R7FA6E2BB3CBB#BC0 supports dynamic clock scaling to balance performance and power consumption.

Does the R7FA6E2BB3CBB#BC0 support USB device functionality without external components?

Yes, the R7FA6E2BB3CBB#BC0 integrates a full USB 2.0 Full-Speed device controller with an on-chip transceiver. It requires only standard USB termination (27 Ω series resistors on DP/DM) and proper 90 Ω differential PCB routing-no external PHY or level-shifting components. The module supports all USB 2.0 transfer types (control, interrupt, bulk, isochronous) across five configurable endpoints and includes dedicated buffer memory. The R7FA6E2BB3CBB#BC0 does not support USB host mode.

How many I/O pins does the R7FA6E2BB3CBB#BC0 provide in its BGA-36 package?

The R7FA6E2BB3CBB#BC0 in the 36-pin BGA package (PLBG0036KA-A) provides 20 general-purpose I/O pins, 4 input-only pins, 21 pull-up resistors, 20 N-channel open-drain outputs, and 5 pins with 5-V tolerance. Pin assignments are defined in Table 1.16 and Figure 1.6 of the R01DS0410EJ0150 datasheet. Unused pins must be tied to VSS or configured as inputs with pull-downs per Renesas recommendations to ensure EMC robustness.

What security features are implemented in hardware on the R7FA6E2BB3CBB#BC0?

The R7FA6E2BB3CBB#BC0 implements Arm TrustZone for Armv8-M, enabling hardware-isolated secure and non-secure execution states. It includes a secure MPU (8 regions), secure/non-secure peripheral attribution, secure pin multiplexing, a 128-bit unique ID, and a True Random Number Generator (TRNG). These features allow secure boot, encrypted firmware updates, and runtime isolation of sensitive operations-without requiring external secure elements. The R7FA6E2BB3CBB#BC0 does not include cryptographic accelerators beyond TRNG.

Can the R7FA6E2BB3CBB#BC0 drive a brushless DC motor directly?

The R7FA6E2BB3CBB#BC0 supports BLDC motor control through its six General PWM Timer (GPT16E) channels, which generate complementary PWM outputs (e.g., GTOUUP/GTOULO) with dead-time insertion. However, it cannot drive motors directly-it requires external gate drivers and power MOSFETs/IGBTs. The R7FA6E2BB3CBB#BC0 provides precise timing, ADC synchronization, and Hall sensor inputs (GTIU/GTIV/GTIW) for sensor-based commutation, making it ideal for compact, integrated motor control boards where space and BOM count are critical.
