Renesas R7FA4E2B93CNE#BA0

Overview

R7FA4E2B93CNE#BA0 from Renesas is a 32-bit Arm® Cortex®-M33 microcontroller operating at up to 100 MHz, featuring 128 KB code flash, 4 KB data flash, and 40 KB SRAM. It integrates USB Full-Speed, CAN FD, I3C, dual SPI, dual SCI, SSIE, CEC, 12-bit ADC/DAC, temperature sensor, GPT16E × 4, AGT × 2, RTC, and TrustZone security - deployed in industrial motor control, smart metering, and USB-connected edge sensors.

For engineers reviewing the R7FA4E2B93CNE#BA0 datasheet, R7FA4E2B93CNE#BA0 pinout, R7FA4E2B93CNE#BA0 application, or R7FA4E2B93CNE#BA0 equivalent, key selection criteria include its 48-pin QFN (7 mm × 7 mm) package, -40°C to +105°C operating range, 2.7–3.6 V supply, secure MPU support, and integrated CAN FD + USBFS for real-time connectivity in constrained embedded systems.

Technical Context

The R7FA4E2B93CNE#BA0 implements Armv8-M architecture with TrustZone-enabled memory isolation across code flash (up to 3 regions), data flash (2 regions), and SRAM (3 regions), plus secure/non-secure MPU instances (8 regions each). Its clock system includes MOSC (8–24 MHz), SOSC (32.768 kHz), HOCO/MOCO/LOCO oscillators, and PLL for flexible frequency synthesis.

Peripheral interconnect leverages Event Link Controller (ELC) for CPU-free signal routing between modules like GPT, ADC, and DMA; Data Transfer Controller (DTC) and 8-channel DMAC enable autonomous data movement; and dual AGT timers operate asynchronously from low-power clocks for wake-up timing without core activation.

FAQ

What is the maximum operating frequency of the R7FA4E2B93CNE#BA0?

The R7FA4E2B93CNE#BA0 operates at a maximum frequency of 100 MHz using its Arm Cortex-M33 core. This performance level is achieved with the internal PLL locked to the main clock oscillator (MOSC) or high-speed on-chip oscillator (HOCO), and is fully supported across its -40°C to +105°C operating temperature range. The R7FA4E2B93CNE#BA0 maintains timing compliance under all specified voltage (2.7–3.6 V) and thermal conditions per Renesas datasheet R01DS0413EJ0150.

Does the R7FA4E2B93CNE#BA0 support CAN FD and USB Full-Speed simultaneously?

Yes, the R7FA4E2B93CNE#BA0 integrates both CAN FD (compliant with ISO 11898-1) and USB 2.0 Full-Speed modules on-chip, and they operate independently with dedicated clock domains and buffers. The CAN FD module supports 4 transmit and 32 receive buffers, while the USBFS module provides 5 configurable pipes including control pipe 0. Both interfaces can be active concurrently in the R7FA4E2B93CNE#BA0 without resource conflict, enabling dual-protocol gateway functionality.

What package type and pin count does the R7FA4E2B93CNE#BA0 use?

The R7FA4E2B93CNE#BA0 uses a 48-pin QFN package (7 mm × 7 mm, 0.5 mm pitch) with an exposed thermal pad. This package variant provides 29 general-purpose I/O pins, 6 of which are 5-V tolerant, and supports all core peripherals including USB_DP/DM, CTX0/CRX0, XTAL/EXTAL, and XCIN/XCOUT. The part number suffix "NE" explicitly denotes this QFN-48 configuration per Renesas' RA4E2 part numbering scheme.

How does the R7FA4E2B93CNE#BA0 implement hardware security?

The R7FA4E2B93CNE#BA0 implements hardware security through Arm TrustZone technology, providing secure/non-secure memory attribution for code flash (up to 3 regions), data flash (2 regions), and SRAM (3 regions). It includes a secure MPU (8 regions), non-secure MPU (8 regions), 128-bit unique ID, and True Random Number Generator (TRNG). Secure pin multiplexing prevents unauthorized reconfiguration of critical I/O functions, and all security features are active and configurable without external components in the R7FA4E2B93CNE#BA0.

What are the key low-power capabilities of the R7FA4E2B93CNE#BA0?

The R7FA4E2B93CNE#BA0 supports multiple low-power modes including Deep Software Standby, with two independent 32-bit AGT timers that operate from the LOCO (32.768 kHz) clock source and retain 1 KB of standby SRAM. It features programmable Low Voltage Detection (LVD) with three selectable thresholds, independent watchdog timers (WDT/IWDT), and clock gating for individual peripherals. These capabilities enable sub-1 µA deep-sleep current in the R7FA4E2B93CNE#BA0 while maintaining RTC calendar accuracy and fast wake-up response for event-driven sensor applications.
