Product details
Overview
R7FA4E10B2CNE#BA0 from Renesas is a 32-bit Arm Cortex-M33 microcontroller operating at up to 100 MHz, featuring 256 KB code flash, 8 KB data flash, 128 KB SRAM with parity, USB 2.0 Full-Speed, Quad SPI, CAN 2.0B, and integrated 12-bit ADC/DAC - deployed in industrial HMI, smart sensor nodes, and USB-connected edge controllers.
For engineers reviewing the R7FA4E10B2CNE#BA0 datasheet, R7FA4E10B2CNE#BA0 pinout, R7FA4E10B2CNE#BA0 application, or R7FA4E10B2CNE#BA0 equivalent, key selection criteria include QFN-48 package footprint, TrustZone-enabled secure boot, battery-backed RTC with calendar mode, and verified 5-V-tolerant I/O on four pins for mixed-voltage interface design.
Technical Context
This MCU implements Armv8-M architecture with dual SysTick timers (Secure/Non-secure), PMSAv8 MPU (8 regions each), and CoreSight ETM-M33 for trace-enabled debugging. It integrates TrustZone security with configurable flash/SRAM regions and peripheral attribution.
The system includes three independent clock domains (MOSC, SOSC, HOCO/MOCO/LOCO), PLL/PLL2 for frequency synthesis, and low-power modes supported by AGT timers, ELC event linking, and DTC/DMAC for autonomous data movement without CPU intervention.

FAQ
What is the maximum operating frequency of the R7FA4E10B2CNE#BA0?
The R7FA4E10B2CNE#BA0 operates at a maximum frequency of 100 MHz using its Arm Cortex-M33 core. This speed is achievable with the internal PLL driven by the main clock oscillator (MOSC) or high-speed on-chip oscillator (HOCO). The MCU supports multiple clock sources including SOSC, LOCO, and PLL2 to maintain timing accuracy across operating conditions.
Does the R7FA4E10B2CNE#BA0 support USB device functionality without an external transceiver?
Yes, the R7FA4E10B2CNE#BA0 integrates a full USB 2.0 Full-Speed transceiver within the die. Its USBFS module supports device mode (including CDC, HID, MSC classes) and host mode, with internal termination and differential signaling on USB_DP/USB_DM pins - eliminating the need for external PHY components in most USB designs.
How many 5-V-tolerant I/O pins does the R7FA4E10B2CNE#BA0 have in the QFN-48 package?
The R7FA4E10B2CNE#BA0 provides exactly four 5-V-tolerant I/O pins in its QFN-48 package: P100, P102, P103, and P104. These pins tolerate input voltages up to 5.8 V (VCC + 4.0 V max), enabling direct interfacing with legacy 5 V logic or sensors without external level shifters.
What security features are implemented in the R7FA4E10B2CNE#BA0?
The R7FA4E10B2CNE#BA0 implements Arm TrustZone for Armv8-M, supporting secure/non-secure memory regions in flash, SRAM, and data flash. It includes access control circuitry, true random number generation (TRNG), and unique chip ID. Note that only these security functions are guaranteed - other SCE9 blocks are not functional per datasheet specification.
Can the R7FA4E10B2CNE#BA0 operate from a battery during main power loss?
Yes, the R7FA4E10B2CNE#BA0 supports battery backup via the VBATT pin (1.65–3.6 V range). When main VCC drops, the RTC, sub-clock oscillator (SOSC), and 128-byte backup registers remain powered - preserving calendar time and critical state across power cycles without external supervision.
