Renesas R7FA6T2BD3CFP#AA0

Overview

R7FA6T2BD3CFP from Renesas is a high-performance 32-bit Arm Cortex-M33 microcontroller designed for real-time motor control and industrial automation. It operates at up to 240 MHz, integrates 512 KB code flash with background operation, 16 KB data flash, 64 KB SRAM with ECC, dual 16-bit ADCs (6.25 Msps), four 12-bit DACs, CAN FD interface, and Secure Cryptographic Engine (SCE5) with TrustZone support. It targets brushless DC motor drives requiring simultaneous analog sampling, high-resolution PWM timing, and secure firmware execution.

For engineers reviewing the R7FA6T2BD3CFP datasheet, R7FA6T2BD3CFP pinout, R7FA6T2BD3CFP application, or R7FA6T2BD3CFP equivalent, key selection criteria include CAN FD compliance, 100-pin LQFP package with dedicated GPT/ADC/PGA pin mapping, 240 MHz deterministic timing, integrated trigonometric (TFU) and IIR filter (IIRFA) accelerators, and hardware-enforced security partitioning across flash/SRAM/peripherals.

Technical Context

The R7FA6T2BD3CFP implements Armv8-M with TrustZone, enabling secure and non-secure execution environments with separate MPU regions (8 per domain), dual SysTick timers, and individual peripheral security attribution. Its memory subsystem includes ECC-protected SRAM, background-programmable flash, and 1 KB standby SRAM with parity.

Real-time control is enabled by ten 32-bit General PWM Timers (GPT32), including four with 156 ps resolution at 200 MHz, four-channel PWM Delay Generation (PDG), and Event Link Controller (ELC) for CPU-free peripheral chaining. Analog subsystem features two noise-shaping SAR ADCs with channel-dedicated sample-and-hold and four programmable gain amplifiers (PGA) for sensor signal conditioning.

FAQ

What is the maximum operating frequency of the R7FA6T2BD3CFP?

The R7FA6T2BD3CFP features an Arm Cortex-M33 core with a maximum operating frequency of 240 MHz. This speed is achievable using the PLL clock source with appropriate configuration of the main oscillator (MOSC) and PLL dividers. The R7FA6T2BD3CFP maintains timing determinism at this frequency for real-time motor control loops and interrupt service routines.

Does the R7FA6T2BD3CFP support CAN FD, and what are its buffer resources?

Yes, the R7FA6T2BD3CFP supports CAN FD (ISO 11898-1) with four transmit buffers and 32 receive buffers. These resources enable high-throughput diagnostic messaging and control frame handling in automotive and industrial networks. The R7FA6T2BD3CFP's CAN FD module operates independently of the CPU via DMA and supports bit rates up to 5 Mbps in the data phase.

How many ADC channels and what resolution does the R7FA6T2BD3CFP provide?

The R7FA6T2BD3CFP integrates two noise-shaping SAR-type ADC units supporting up to 16-bit resolution and a combined sampling rate of 6.25 Msps. It offers up to 29 analog input channels, including dedicated PGA inputs (PGAIN0–PGAIN3) and temperature sensor integration. The R7FA6T2BD3CFP's channel-dedicated sample-and-hold circuitry enables true simultaneous sampling across multiple channels for multi-phase motor current measurement.

What security features are implemented in the R7FA6T2BD3CFP?

The R7FA6T2BD3CFP includes the Secure Cryptographic Engine (SCE5) for AES encryption/decryption and GHASH generation, a 128-bit unique ID, and full Arm TrustZone support. TrustZone enables hardware-isolated secure and non-secure memory regions (flash/SRAM) and peripheral attribution. The R7FA6T2BD3CFP also supports device lifecycle management for secure provisioning and firmware rollback protection.

What package type and pin count does the R7FA6T2BD3CFP use?

The R7FA6T2BD3CFP uses a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch), designated by the "FP" suffix in its part number. This package provides full access to all peripherals including dual ADCs, ten GPT channels, CAN FD, six SCI interfaces, and dedicated motor control PWM outputs. The R7FA6T2BD3CFP's pin assignment is documented in Figure 1.3 of the official datasheet R01DS0400EJ0150.
