Renesas R7FA6E2BB3CFM#BA0

Overview

R7FA6E2BB3CFM 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 Arm TrustZone® security-designed for industrial HMI, smart metering, and secure edge node control.

For engineers reviewing the R7FA6E2BB3CFM datasheet, R7FA6E2BB3CFM pinout, R7FA6E2BB3CFM application, or R7FA6E2BB3CFM equivalent, key selection considerations include its 64-pin LQFP package, -40°C to +105°C operation, dual secure/non-secure Systick timers, and integrated QSPI interface for external flash boot.

Technical Context

The R7FA6E2BB3CFM implements Armv8-M architecture with TrustZone®, supporting secure and non-secure execution states via separate MPU regions (8 per domain) and configurable memory attribution. Its clock system includes MOSC (8–24 MHz), SOSC (32.768 kHz), HOCO/MOCO/LOCO oscillators, and PLL-enabling precise timing for USBFS, RTC, and CANFD.

Peripheral integration centers on deterministic real-time control: six GPT16E timers support BLDC motor PWM with complementary outputs (GTOUUP/GTOULO), while AGT × 2 and ELC enable low-power event-driven operation without CPU intervention. The DTC and 8-channel DMAC offload data movement for ADC/DAC/USB/QSPI transfers.

FAQ

What is the maximum operating frequency of the R7FA6E2BB3CFM?

The R7FA6E2BB3CFM operates at a maximum CPU frequency of 200 MHz using its Arm Cortex-M33 core. This frequency is achieved via the on-chip PLL driven by the main clock oscillator (MOSC) or high-speed on-chip oscillator (HOCO). The R7FA6E2BB3CFM maintains this speed across its full industrial temperature range (-40°C to +105°C) with appropriate voltage supply (2.7–3.6 V).

Does the R7FA6E2BB3CFM support USB device functionality without an external transceiver?

Yes, the R7FA6E2BB3CFM integrates a full-speed USB 2.0 device controller with an on-chip transceiver. Pins USB_DP and USB_DM connect directly to the USB bus with only 27 Ω series resistors required. The R7FA6E2BB3CFM supports all USB 2.0 transfer types (control, bulk, interrupt, isochronous) and includes 5 configurable endpoints with dedicated buffer memory.

How many analog-to-digital converter channels does the R7FA6E2BB3CFM provide?

The R7FA6E2BB3CFM includes a 12-bit successive approximation ADC (ADC12) with up to 12 selectable analog input channels. Inputs include external pins (AN0n), internal temperature sensor output, and internal reference voltage-enabling simultaneous monitoring of multiple sensors or system parameters within a single R7FA6E2BB3CFM device.

What security features are implemented in hardware on the R7FA6E2BB3CFM?

The R7FA6E2BB3CFM implements Arm TrustZone® for Armv8-M, providing hardware-isolated secure and non-secure states. It includes secure MPU regions (3 for code flash, 2 for data flash, 3 for SRAM), secure pin multiplexing, a 128-bit unique ID, and a True Random Number Generator (TRNG). These features are active upon reset and require no external components to enforce secure boot or runtime isolation.

Which package type corresponds to the R7FA6E2BB3CFM part number?

The R7FA6E2BB3CFM uses the 64-pin LQFP package (PLQP0064KB-C), measuring 10 mm × 10 mm with 0.5 mm pitch. This package provides 45 general-purpose I/O pins, 5 dedicated input-only pins, and supports 5-V tolerant inputs on 11 pins-making it suitable for industrial PCB designs requiring mechanical robustness and hand-soldering compatibility.
