Product details
Overview
R7FA6T3BB3CNE#BA0 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, 40 KB SRAM, USB Full-Speed, CAN FD, I3C, and dual 12-bit DACs. It targets motor control and industrial real-time applications requiring secure, high-precision analog interfaces and deterministic timing.
For engineers reviewing the R7FA6T3BB3CNE#BA0 datasheet, R7FA6T3BB3CNE#BA0 pinout, R7FA6T3BB3CNE#BA0 application, or R7FA6T3BB3CNE#BA0 equivalent, key selection criteria include its QFN-48 package with 29 I/O pins, TrustZone-enabled security partitioning, integrated trigonometric function unit (TFU), and support for BLDC motor PWM generation via six GPT16E timers.
Technical Context
The R7FA6T3BB3CNE#BA0 implements Armv8-M architecture with TrustZone, supporting secure/non-secure MPU regions (8+8), dual SysTick timers, and CoreSight™ ETM-M33 trace. Its memory subsystem includes ECC-protected SRAM and 100,000-cycle data flash for firmware updates.
Real-time responsiveness is enhanced by Event Link Controller (ELC) for CPU-free peripheral linking, Data Transfer Controller (DTC), and an 8-channel DMAC. The TFU accelerates sine/cosine and arctangent/sqrt(x²+y²) calculations-critical for field-oriented control in motor drives.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7FA6T3BB3CFM | 64-pin LQFP package, 45 I/O pins, same core/peripherals | Higher I/O count and larger footprint for complex board layouts with multiple analog/sensor interfaces | Select when needing >29 GPIOs or additional ADC channels beyond QFN-48 pinout constraints |

FAQ
What is the maximum operating frequency of the R7FA6T3BB3CNE#BA0?
The R7FA6T3BB3CNE#BA0 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). System clocks for peripherals-including USBFS, CANFD, and ADC12-are derived from this source with configurable dividers to meet individual timing requirements without compromising real-time determinism.
Does the R7FA6T3BB3CNE#BA0 support USB device functionality without an external transceiver?
Yes, the R7FA6T3BB3CNE#BA0 integrates a full-speed USB 2.0 transceiver compliant with Universal Serial Bus Specification 2.0. It supports all standard transfer types (control, interrupt, bulk, isochronous) and includes internal buffer memory for up to five pipes. No external PHY is required; only standard USB-series 27 Ω resistors and a 1.5 kΩ pull-up on USB_DP are needed for device enumeration.
How many analog input channels does the R7FA6T3BB3CNE#BA0 support?
The R7FA6T3BB3CNE#BA0 supports up to 12 analog input channels via its 12-bit ADC12 module. These channels include dedicated pins (AN000–AN016), internal sources (temperature sensor, reference voltage), and pseudo-differential inputs (PGAVSS000). All channels are accessible in the QFN-48 package, with 10 physical ADC input pins mapped across P0xx and P1xx ports per the pin list in R01DS0414EJ0140.
What security features are implemented in the R7FA6T3BB3CNE#BA0?
The R7FA6T3BB3CNE#BA0 implements Arm TrustZone for hardware-enforced secure/non-secure world separation, including secure MPU regions for code/data/SRAM, secure pin multiplexing, a 128-bit unique ID, and a True Random Number Generator (TRNG). These features enable secure boot, encrypted firmware updates, and protected key storage-all verified against PSA Certified Level 2 requirements in the RA6T3 security documentation.
Can the R7FA6T3BB3CNE#BA0 generate complementary PWM signals with programmable dead time?
Yes, the R7FA6T3BB3CNE#BA0's six General PWM Timer 16-bit Enhanced (GPT16E) modules support complementary PWM output pairs (e.g., GTIOCnA/GTIOCnB) with hardware-configurable dead-time insertion. Each channel can be independently configured for center-aligned or edge-aligned modes, and dead-time values are set via dedicated registers (GTDTCR) with resolution down to one system clock cycle-enabling safe gate driving for IGBTs and MOSFETs in inverter topologies.
