FAQ

What is the maximum operating frequency and core architecture of the R7FA4T1B93CFM?

The R7FA4T1B93CFM features an Arm Cortex-M33 core with a maximum operating frequency of 100 MHz. It implements the Armv8-M architecture with TrustZone security extension and revision r0p4-00rel0. The core supports both secure and non-secure execution states, and includes a dual-instance SysTick timer driven by either the system clock or LOCO.

Does the R7FA4T1B93CFM support CAN FD, and what are its buffer capabilities?

Yes, the R7FA4T1B93CFM includes a Control Area Network with Flexible Data-Rate (CANFD) module compliant with ISO 11898-1. It supports both classical CAN and CAN FD frames, with 4 transmit buffers and 32 receive buffers. This enables high-throughput, deterministic communication in automotive and industrial networks where payload size and bit rate flexibility are critical.

What analog peripherals are integrated into the R7FA4T1B93CFM?

The R7FA4T1B93CFM integrates a 12-bit A/D Converter (ADC12) with up to 12 input channels, 3 sample-and-hold circuits, and 3 programmable gain amplifiers (PGA); two 12-bit D/A Converters (DAC12); three High-Speed Analog Comparators (ACMPHS); and an on-chip Temperature Sensor (TSN). These peripherals support precision analog signal acquisition, actuation, and condition monitoring without external components.

What package type and pin count does the R7FA4T1B93CFM use?

The R7FA4T1B93CFM uses a 64-pin LQFP package (PLQP0064KB-C), measuring 10 mm × 10 mm with 0.5 mm pitch. It provides 45 general-purpose I/O pins, 11 of which are 5-V tolerant, and includes dedicated pins for CAN FD, I3C, dual SPI, dual SCI, and 3-phase BLDC PWM outputs - all validated in the official Renesas pin assignment diagram for LQFP64.

How does the R7FA4T1B93CFM implement security features?

The R7FA4T1B93CFM implements Arm TrustZone for Armv8-M, enabling hardware-enforced isolation between secure and non-secure code and data. It supports up to three secure regions in code flash, two in data flash, and three in SRAM. Additional security features include a 128-bit unique ID, True Random Number Generator (TRNG), secure pin multiplexing, and register write protection - all accessible and configurable within the R7FA4T1B93CFM's security framework.
