Overview
R7FA6T3BB3CFJ#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 - designed for real-time motor control and industrial edge sensing applications.
For engineers reviewing the R7FA6T3BB3CFJ#BA0 datasheet, R7FA6T3BB3CFJ#BA0 pinout, R7FA6T3BB3CFJ#BA0 application, or R7FA6T3BB3CFJ#BA0 equivalent, this page delivers verified specifications, package mapping to 32-pin LQFP, functional pin assignments, TrustZone security implementation, and validated alternative MCUs for motor drive and industrial automation designs.
Technical Context
The R7FA6T3BB3CFJ#BA0 implements Armv8-M with TrustZone, supporting secure/non-secure MPU regions (8+8), dual SysTick timers, and CoreSight™ ETM-M33 for trace-enabled debugging. It integrates a Trigonometric Function Unit (TFU) for real-time sine/cosine and arctangent/sqrt(x²+y²) computation - critical for field-oriented control (FOC) algorithms.
Its analog subsystem includes a 12-bit ADC12 with 3 sample-and-hold circuits and 3 programmable gain amplifiers, plus 3 high-speed comparators (ACMPHS) with internal DAC12 reference routing - enabling fast overcurrent protection and sensorless BLDC commutation without external signal conditioning.

FAQ
What is the maximum operating frequency of the R7FA6T3BB3CFJ#BA0?
The R7FA6T3BB3CFJ#BA0 operates at a maximum CPU frequency of 200 MHz using its Arm Cortex-M33 core. This frequency is achievable with the on-chip PLL driven by the main clock oscillator (MOSC) or high-speed on-chip oscillator (HOCO). The device maintains timing integrity across its full -40°C to +105°C operating range, with voltage supply specified at 2.7–3.6 V.
Does the R7FA6T3BB3CFJ#BA0 support USB Full-Speed functionality?
No, the R7FA6T3BB3CFJ#BA0 does not support USB Full-Speed. Although the RA6T3 Group datasheet lists USBFS as a feature, the 32-pin LQFP variant (R7FA6T3BB3CFJ#BA0) omits the USB_DP and USB_DM pins entirely - confirmed by pin assignment Figure 1.6 and Table 1.16. USBFS is only available on 48-pin and larger packages (e.g., R7FA6T3BB3CFL, R7FA6T3BB3CFM).
How many analog input channels does the ADC12 support on the R7FA6T3BB3CFJ#BA0?
The R7FA6T3BB3CFJ#BA0 supports up to 5 analog input channels on its ADC12 module, as specified in Table 1.14 (Function Comparison) for the 32-pin variants. These channels are mapped to pins P000–P003, P100, and P102 - with additional flexibility provided by the 3 integrated programmable gain amplifiers (PGA) and sample-and-hold circuits for precision current sensing.
Is CAN FD supported on the R7FA6T3BB3CFJ#BA0?
No, CAN FD is not supported on the R7FA6T3BB3CFJ#BA0. Per Table 1.14, the 32-pin LQFP variant excludes CANFD functionality. Pin-level validation confirms absence of CRX0 and CTX0 signals in the 32-pin pinout (Figures 1.6–1.7 and Table 1.16). CAN FD is available only on 48-pin and larger RA6T3 packages.
What security features are implemented in the R7FA6T3BB3CFJ#BA0?
The R7FA6T3BB3CFJ#BA0 implements Arm TrustZone for Armv8-M, providing hardware-isolated secure and non-secure memory regions for flash (up to 3), data flash (up to 2), and SRAM (up to 3). It also includes a 128-bit unique ID, True Random Number Generator (TRNG), and secure pin multiplexing - all documented in Section 1.11 of the R01DS0414EJ0140 datasheet for this exact part number.
