Renesas R7FA6T2BD3CFP#BA0

Overview

R7FA6T2BD3CFP from Renesas is a high-performance 32-bit Arm Cortex-M33 microcontroller targeting motor control and industrial real-time applications. 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), CAN FD interface, and Secure Cryptographic Engine (SCE5) with TrustZone support. It is used in 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 its 100-pin LQFP package, CAN FD compliance, dual ADC with channel-dedicated sample-and-hold, GPT32 timers with 156 ps resolution, and integrated TFU/IIRFA for real-time signal processing in motion control systems.

Technical Context

The R7FA6T2BD3CFP implements Armv8-M architecture with TrustZone security partitioning, supporting up to three secure/non-secure memory regions in flash and SRAM. Its dual ADC units feature noise-shaping SAR architecture, 29 total analog input channels, and four programmable gain amplifiers-enabling simultaneous sampling of multiple motor phase currents with pseudo-differential inputs.

It integrates ten General PWM Timer (GPT32) channels-including four with high-resolution mode (156 ps at 200 MHz)-and dedicated hardware for BLDC motor control (e.g., GTIU/GTIV/GTIW inputs, GTOUUP/GTOULO outputs). The Event Link Controller (ELC) enables direct peripheral-to-peripheral triggering without CPU intervention, critical for deterministic motor commutation timing.

FAQ

What is the maximum operating frequency and core architecture of the R7FA6T2BD3CFP?

The R7FA6T2BD3CFP features an Arm Cortex-M33 core operating at up to 240 MHz, based on the Armv8-M architecture with security extensions. It implements TrustZone for hardware-enforced separation of secure and non-secure code execution, and includes an Arm Memory Protection Unit (MPU) with eight regions each for secure and non-secure states. This architecture enables certified functional safety and secure firmware updates in industrial deployments.

Does the R7FA6T2BD3CFP support CAN FD, and what are its physical layer capabilities?

Yes, the R7FA6T2BD3CFP supports CAN with Flexible Data-rate (CAN FD) per ISO 11898-1, including both classical CAN frames and CAN FD frames. It provides one CAN FD module with four transmit buffers and 32 receive buffers, and uses dedicated CRX0/CTX0 pins for differential signaling. The module supports bit rates up to 5 Mbps in the data phase, enabling high-throughput diagnostics and firmware updates in industrial networks.

How many ADC channels does the R7FA6T2BD3CFP have, and what is their resolution and sampling capability?

The R7FA6T2BD3CFP integrates two noise-shaping SAR-type ADC units supporting up to 16-bit resolution and an aggregate sampling rate of 6.25 Msps. It provides 29 total analog input channels, including dedicated sample-and-hold circuits for six channels and four programmable gain amplifiers. Inputs support single-ended, pseudo-differential, and internal reference selections-enabling simultaneous current sensing across all three motor phases with minimal external circuitry.

What hardware accelerators are included in the R7FA6T2BD3CFP for real-time signal processing?

The R7FA6T2BD3CFP includes two dedicated hardware accelerators: the Trigonometric Function Unit (TFU), which computes sine, cosine, arctangent, and hypotenuse in parallel; and the IIR Filter Accelerator (IIRFA), supporting 16-channel biquad filtering with up to 32 cascaded stages. These units offload computationally intensive motor control tasks from the CPU-reducing FOC loop latency and enabling deterministic execution at >20 kHz update rates.

What package type and pin count does the R7FA6T2BD3CFP use, and is it pin-compatible with other RA6T2 variants?

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 and PLQP0100KB-B package code. It shares identical pinout and footprint with other RA6T2 100-pin variants such as R7FA6T2AD3CFP and R7FA6M2AF3CFP-enabling hardware reuse across different memory and feature configurations without PCB redesign.
