Renesas R7FA6E2B93CFM#AA0

Overview

R7FA6E2B93CFM from Renesas is a 32-bit Arm® Cortex®-M33 microcontroller operating at up to 200 MHz, featuring 128 KB code flash, 4 KB data flash, and 40 KB SRAM. It integrates USB Full-Speed, CAN FD, Quad SPI, I3C, 12-bit ADC/DAC, and TrustZone security - deployed in industrial HMI, smart metering, and motor control systems requiring real-time responsiveness and functional safety.

For engineers reviewing the R7FA6E2B93CFM datasheet, R7FA6E2B93CFM pinout, R7FA6E2B93CFM application, or R7FA6E2B93CFM equivalent, key selection criteria include its -40°C to +105°C temperature rating, 64-pin LQFP package with 45 GPIOs, dual 12-bit DACs, and secure boot capability enabled by Arm TrustZone and 128-bit unique ID.

Technical Context

The R7FA6E2B93CFM implements Armv8-M architecture with TrustZone, supporting secure/non-secure execution states and MPU regions for both memory spaces. Its clock system includes PLL, HOCO/MOCO/LOCO oscillators, and CAC for frequency accuracy monitoring - enabling deterministic timing in safety-critical firmware.

Peripheral integration centers on event-driven operation: ELC links triggers across modules (e.g., ADC start → GPT capture), DTC handles low-overhead data movement, and DMAC provides 8-channel burst transfers. The dual AGT timers operate asynchronously from LOCO, sustaining timing functions in low-power modes without CPU wake-up.

FAQ

What is the maximum operating frequency of the R7FA6E2B93CFM?

The R7FA6E2B93CFM features an Arm Cortex-M33 core with a maximum operating frequency of 200 MHz. This clock speed is achieved using the on-chip PLL driven by the main crystal oscillator (8–24 MHz) or high-speed on-chip oscillator (HOCO). The R7FA6E2B93CFM maintains full peripheral functionality at this frequency, including USBFS, CANFD, and QSPI, making it suitable for real-time control and protocol processing tasks.

Does the R7FA6E2B93CFM support secure boot and runtime isolation?

Yes, the R7FA6E2B93CFM implements Arm TrustZone technology to enforce hardware-isolated secure and non-secure execution states. It includes a secure MPU with eight regions for code flash and SRAM, secure pin multiplexing, and a 128-bit unique ID. These features enable verified secure boot, encrypted firmware updates, and runtime separation of critical security functions from application code - essential for industrial devices requiring IEC 62443 compliance.

Which package type does the R7FA6E2B93CFM use, and how many GPIOs are available?

The R7FA6E2B93CFM uses a 64-pin LQFP package (PLQP0064KB-C, 10 mm × 10 mm, 0.5 mm pitch) with 45 general-purpose I/O pins. Of these, 11 pins support 5-V tolerance, 45 support N-ch open-drain operation, and 46 include internal pull-up resistors. The pinout is fully documented in Figure 1.3 and Table 1.16 of the R01DS0410EJ0150 datasheet, confirming compatibility with standard LQFP PCB footprints.

Can the R7FA6E2B93CFM interface directly with external serial flash memory?

Yes, the R7FA6E2B93CFM includes a dedicated Quad Serial Peripheral Interface (QSPI) controller that supports XIP (execute-in-place) operation with standard serial NOR flash devices. It provides four data lines (QIO0–QIO3), configurable clock polarity/phase, and hardware address translation - enabling direct code execution and high-speed data streaming without external glue logic. This capability reduces system BOM and simplifies firmware update architectures.

What analog peripherals are integrated into the R7FA6E2B93CFM?

The R7FA6E2B93CFM integrates a 12-bit successive approximation ADC12 with up to 12 input channels, two independent 12-bit DAC12 modules, and an on-die temperature sensor (TSN). The ADC supports internal reference voltage and temperature sensor inputs; DAC outputs are rail-to-rail and support synchronous update. These analog resources enable sensor signal acquisition, actuator control, and thermal monitoring - all without external precision components.
