Renesas R7FA4E10B2CFM#BA0

Overview

R7FA4E10B2CFM from Renesas Electronics is a 32-bit Arm Cortex-M33 microcontroller operating at up to 100 MHz, featuring 256 KB code flash, 8 KB data flash, and 128 KB SRAM with parity. It integrates USB 2.0 Full-Speed, Quad SPI, CAN 2.0B, 12-bit ADC (9 channels), 12-bit DAC, and TrustZone security for industrial control and IoT edge nodes.

For engineers reviewing the R7FA4E10B2CFM datasheet, R7FA4E10B2CFM pinout, R7FA4E10B2CFM application, or R7FA4E10B2CFM equivalent, this MCU delivers verified timing-critical peripheral coexistence (USBFS + QSPI + CAN), deterministic low-power operation via AGT timers and Deep Software Standby, and hardware-enforced memory isolation across secure/non-secure worlds.

Technical Context

The R7FA4E10B2CFM implements Armv8-M with TrustZone, supporting dual MPU instances (8 regions each for secure/non-secure states) and two independent SysTick timers. Its clock system includes PLL, HOCO/MOCO/LOCO oscillators with trim, and CAC for real-time frequency accuracy monitoring.

Peripheral integration centers on event-driven autonomy: ELC links 5 AGT timers, GPT32/GPT16, ADC12, and USBFS without CPU intervention; DTC and 8-channel DMAC enable zero-CPU data movement; and SCE9 provides access control, RNG, and unique ID-verified as functional per datasheet Rev.1.30.

FAQ

What is the maximum operating frequency of the R7FA4E10B2CFM?

The R7FA4E10B2CFM features an Arm Cortex-M33 core with a maximum operating frequency of 100 MHz. This is achieved using the on-chip PLL driven by the main oscillator (MOSC) or high-speed on-chip oscillator (HOCO). The R7FA4E10B2CFM maintains full peripheral functionality-including USBFS, QSPI, and CAN-at this speed, as validated in Renesas datasheet R01DS0391EJ0130.

Does the R7FA4E10B2CFM support TrustZone security?

Yes, the R7FA4E10B2CFM implements Arm TrustZone for Armv8-M, enabling hardware-enforced separation between secure and non-secure software states. It supports up to three secure regions in code flash, two in data flash, and three in SRAM. The SCE9 module provides verified access control, random number generation, and unique ID-functions confirmed operational per datasheet Rev.1.30.

What package type does the R7FA4E10B2CFM use?

The R7FA4E10B2CFM uses a 64-pin LQFP package (PLQP0064KB-C), measuring 10 mm × 10 mm with 0.5 mm pitch. It provides 43 general-purpose I/O pins, including 9 that are 5-V tolerant (P205, P206, P400–P411), and supports operating temperatures from –40°C to +85°C. This package is pin-compatible with other RA4E1 variants like R7FA4E10D2CFM.

Can the R7FA4E10B2CFM operate as a USB host?

Yes, the R7FA4E10B2CFM's USB 2.0 Full-Speed module supports both device and host modes per Universal Serial Bus Specification 2.0. In host mode, it supports low-speed and full-speed transfers and manages up to 10 pipes. The R7FA4E10B2CFM includes an internal transceiver-no external PHY is required-making it suitable for USB peripheral aggregation in edge gateways.

What analog peripherals are integrated into the R7FA4E10B2CFM?

The R7FA4E10B2CFM integrates a 12-bit successive-approximation ADC (ADC12) with up to 9 selectable input channels and a 12-bit DAC (DAC12) with one output channel. Both are referenced to dedicated analog supplies (AVCC0/AVSS0) and support independent voltage references (VREFH0/VREFL0). These peripherals are fully functional and characterized across the –40°C to +85°C range per datasheet Section 2.1.
