Renesas R7FA6E2BB3CNH#BA0

Overview

R7FA6E2BB3CNH 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, smart sensor nodes, and low-power gateway controllers.

For engineers reviewing the R7FA6E2BB3CNH datasheet, R7FA6E2BB3CNH pinout, R7FA6E2BB3CNH application, or R7FA6E2BB3CNH equivalent, this page delivers verified package mapping (32-pin QFN), validated peripheral set, confirmed security architecture (TrustZone with 3 flash/SRAM regions), and real-world timing & interface constraints for rapid schematic integration and firmware bring-up.

Technical Context

The R7FA6E2BB3CNH implements Armv8-M with TrustZone, supporting secure/non-secure execution states with separate MPU configurations (8 regions each) and dual SysTick timers. Its clock system includes MOSC (8–24 MHz), SOSC (32.768 kHz), HOCO/MOCO/LOCO oscillators, and PLL - enabling precise frequency synthesis and low-power operation down to Deep Software Standby mode.

Peripheral interconnect uses Event Link Controller (ELC) for CPU-free signal routing between GPT, ADC, AGT, and RTC; DMA support includes 8-channel DMAC and DTC for autonomous data movement. Analog subsystem comprises 12-bit ADC12 (12 channels), two 12-bit DAC12 outputs, and on-die temperature sensor (TSN) with linear voltage output referenced to VREFH0/VREFL0.

FAQ

What is the maximum operating frequency of the R7FA6E2BB3CNH?

The R7FA6E2BB3CNH operates at a maximum CPU frequency of 200 MHz using its Arm Cortex-M33 core. This speed is achievable with the on-chip PLL driven by the main crystal oscillator (MOSC) or high-speed on-chip oscillator (HOCO). The R7FA6E2BB3CNH datasheet confirms this rating across the full −40°C to +105°C temperature range under 2.7–3.6 V supply conditions.

Does the R7FA6E2BB3CNH support USB device functionality without an external PHY?

Yes, the R7FA6E2BB3CNH integrates a full USB 2.0 Full-Speed transceiver (USBFS module) with on-die termination and differential signaling. It supports all USB 2.0 transfer types (control, bulk, interrupt, isochronous) and requires only external 27 Ω series resistors on USB_DP/USB_DM - no external PHY or level shifter is needed for standard USB device operation.

How many analog input channels does the ADC12 support on the R7FA6E2BB3CNH?

The R7FA6E2BB3CNH includes a 12-bit successive approximation ADC12 with up to 12 selectable analog input channels (AN0n). These channels accept signals referenced to VREFH0/VREFL0 and include dedicated inputs for the on-die temperature sensor (TSN) and internal reference voltage - all accessible in the 32-pin QFN package per the pin list in R01DS0410EJ0150.

Is TrustZone security implemented in hardware on the R7FA6E2BB3CNH?

Yes, TrustZone for Armv8-M is implemented in silicon on the R7FA6E2BB3CNH. It provides hardware-enforced isolation between secure and non-secure worlds, including configurable memory regions (up to three in code flash, two in data flash, three in SRAM) and individual peripheral security attribution - all documented in the R7FA6E2BB3CNH security chapter and verified in the RA6E2 Group reference manual.

What package type and pin count does the R7FA6E2BB3CNH use?

The R7FA6E2BB3CNH uses a 32-pin QFN package (5 mm × 5 mm, 0.5 mm pitch) with an exposed die pad. This matches the "NH" suffix in the part number and is confirmed in Table 1.13 and Figure 1.7 of the R01DS0410EJ0150 datasheet. It provides 16 general-purpose I/O pins, 4 with 5-V tolerance, and dedicated pins for USB, CAN FD, QSPI, and debug interfaces.
