Product details
Overview
R7FA6T3BB3CFL#AA0 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, dual SPI, dual SCI, 12-bit ADC with PGA, dual 12-bit DAC, and TrustZone security - designed for real-time motor control and industrial automation systems.
For engineers reviewing the R7FA6T3BB3CFL#AA0 datasheet, R7FA6T3BB3CFL#AA0 pinout, R7FA6T3BB3CFL#AA0 application, or R7FA6T3BB3CFL#AA0 equivalent, key selection criteria include its 48-pin LQFP package, -40°C to +105°C operation, integrated trigonometric function unit (TFU), 6-channel GPT16E PWM timers, and secure peripheral attribution via Arm TrustZone.
Technical Context
The R7FA6T3BB3CFL#AA0 implements Armv8-M architecture with TrustZone, supporting secure/non-secure MPU regions (8+8), dual SysTick timers, and CoreSight ETM-M33 for trace-enabled debugging. Its memory subsystem includes ECC-protected SRAM (8 KB) and parity-protected SRAM (32 KB), with 4 KB data flash rated for 100,000 P/E cycles.
Real-time control is enabled by Event Link Controller (ELC) for CPU-free peripheral chaining, Data Transfer Controller (DTC), and 8-channel DMAC. The TFU accelerates sine/cosine and arctangent/sqrt(x²+y²) computations - critical for field-oriented control (FOC) in BLDC/PMSM motor drives.

FAQ
What is the maximum operating frequency of the R7FA6T3BB3CFL#AA0?
The R7FA6T3BB3CFL#AA0 operates at a maximum frequency of 200 MHz using its Arm Cortex-M33 core. This is achieved via internal PLL multiplication of supported clock sources including MOSC (8–24 MHz), HOCO (16/18/20 MHz), or external crystals. The 200 MHz clock drives both core execution and peripheral timing, enabling high-bandwidth motor control loops and real-time data processing in the R7FA6T3BB3CFL#AA0.
Does the R7FA6T3BB3CFL#AA0 support CAN FD communication?
Yes, the R7FA6T3BB3CFL#AA0 integrates a CAN with Flexible Data-Rate (CANFD) module compliant with ISO 11898-1. It supports both classical CAN frames and CAN FD frames up to 5 Mbps, with 4 transmit buffers and 32 receive buffers. The CTX0 and CRX0 pins provide direct connection to an external CAN transceiver, making the R7FA6T3BB3CFL#AA0 suitable for high-speed industrial networking and motor drive command interfaces.
What analog peripherals are included in the R7FA6T3BB3CFL#AA0?
The R7FA6T3BB3CFL#AA0 includes a 12-bit ADC12 with 8 input channels, 3 programmable gain amplifiers (PGA), 2× 12-bit DAC12, 3 high-speed analog comparators (ACMPHS), and an on-die temperature sensor (TSN). These peripherals are directly accessible via dedicated analog pins (VREFH0/VREFL0, AN0n, DAn, IVREFn, IVCMPn) and support simultaneous sampling, PGA gain switching, and comparator output routing to timers - all essential for precision motor current sensing and thermal monitoring in the R7FA6T3BB3CFL#AA0.
How does the Trigonometric Function Unit (TFU) benefit motor control applications using the R7FA6T3BB3CFL#AA0?
The TFU in the R7FA6T3BB3CFL#AA0 accelerates sine/cosine and arctangent/sqrt(x²+y²) calculations in hardware, reducing computation time from >10 µs (software-based) to under 1 µs. This enables field-oriented control (FOC) loop execution at >20 kHz, improves torque ripple suppression, and offloads the Cortex-M33 core - allowing the R7FA6T3BB3CFL#AA0 to maintain real-time responsiveness while handling communication, safety checks, and diagnostics concurrently.
What package type and pin count does the R7FA6T3BB3CFL#AA0 use?
