Renesas R7FA6E2BB3CFM#AA0

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, 12-bit ADC/DAC, and TrustZone security - deployed in industrial HMI, motor control, and secure IoT edge nodes.

For engineers reviewing the R7FA6E2BB3CFM datasheet, R7FA6E2BB3CFM pinout, R7FA6E2BB3CFM application, or R7FA6E2BB3CFM equivalent, this page delivers verified specifications, LQFP-64 pin mapping, real-world use cases, and two validated alternative parts for design flexibility and supply continuity.

Technical Context

The R7FA6E2BB3CFM implements Armv8-M with TrustZone, enabling secure/non-secure execution environments with separate MPU regions (8 per domain) and hardware-enforced peripheral attribution. Its dual Systick timers and CoreSight ETM-M33 support deterministic real-time scheduling and trace-based debugging.

System-level timing is managed via multiple clock sources - including MOSC (8–24 MHz), SOSC (32.768 kHz), HOCO/MOCO/LOCO oscillators, and PLL - with Clock Frequency Accuracy Measurement (CAC) for calibration-critical applications. The Event Link Controller (ELC) enables zero-CPU-intervention peripheral chaining between GPT, ADC, and DMA.

FAQ

What is the maximum operating frequency of the R7FA6E2BB3CFM?

The R7FA6E2BB3CFM features an Arm Cortex-M33 core with a maximum operating frequency of 200 MHz. This is achieved using the on-chip PLL driven by the main clock oscillator (MOSC) or high-speed on-chip oscillator (HOCO). The R7FA6E2BB3CFM maintains timing integrity across its full −40°C to +105°C operating range, with clock accuracy verified via the integrated Clock Frequency Accuracy Measurement Circuit (CAC).

Does the R7FA6E2BB3CFM support USB device functionality without external components?

Yes, the R7FA6E2BB3CFM integrates a full-featured USB 2.0 Full-Speed module (USBFS) with an on-chip transceiver. Pins USB_DP and USB_DM connect directly to the USB connector, eliminating the need for external PHY or level-shifting components. The module supports all USB 2.0 transfer types (control, bulk, interrupt, isochronous) and includes 5 configurable endpoints with dedicated buffer memory - fully implemented in the R7FA6E2BB3CFM silicon.

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 signals (AN0n), internal temperature sensor output, and internal reference voltage - all accessible through the same ADC hardware. Channel selection, sampling time, and trigger sources (software, timer, or peripheral event) are fully configurable in the R7FA6E2BB3CFM's register set.

What security features are implemented in hardware on the R7FA6E2BB3CFM?

The R7FA6E2BB3CFM implements Arm TrustZone for Armv8-M at the silicon level, enabling secure/non-secure world separation with dedicated MPUs for each domain. Additional hardware security includes a True Random Number Generator (TRNG), 128-bit unique ID, secure pin multiplexing, and register write protection (PRCR). These features are intrinsic to the R7FA6E2BB3CFM die and require no external components to activate or maintain.

Which package type corresponds to the R7FA6E2BB3CFM part number suffix "FM"?

The suffix "FM" in R7FA6E2BB3CFM denotes 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 11 5-V-tolerant inputs - confirmed in Renesas' official part numbering guide and datasheet Table 1.13. The R7FA6E2BB3CFM is not offered in QFN or BGA variants under this specific suffix.
