Renesas R7FA4M2AC3CFP#AA0

Overview

R7FA4M2AC3CFP from Renesas is a 32-bit Arm Cortex-M33 microcontroller operating at up to 100 MHz, featuring 384 KB code flash, 8 KB data flash, and 128 KB SRAM with parity/ECC. It integrates USB 2.0 Full-Speed, SDHI, Quad SPI, CAN, dual 12-bit DACs, 12-bit ADC (22-channel), CTSU, RTC with VBATT support, and Secure Crypto Engine 9 with TrustZone for secure embedded control in industrial HMI and connected edge devices.

For engineers reviewing the R7FA4M2AC3CFP datasheet, R7FA4M2AC3CFP pinout, R7FA4M2AC3CFP application, or R7FA4M2AC3CFP equivalent, key selection considerations include its 100-pin LQFP package, -40°C to +105°C industrial temperature grade, integrated security engine (AES/RSA/ECC/SHA256), and peripheral set optimized for motor control, secure gateway, and touch-enabled human-machine interfaces.

Technical Context

The R7FA4M2AC3CFP implements Armv8-M architecture with TrustZone-enforced secure/non-secure execution states, dual Systick timers, and PMSAv8 MPU with eight regions per domain. Its memory subsystem includes background operation-capable flash and ECC-protected SRAM, enabling safe firmware updates and real-time determinism.

Peripheral integration centers on deterministic event-driven operation: Event Link Controller (ELC) enables CPU-free peripheral chaining; DTC and 8-channel DMAC offload data movement; AGT timers provide low-power asynchronous timing; and GPT32/GPT16 modules support precise PWM generation for BLDC motor control and industrial actuation.

FAQ

What is the maximum operating frequency and core architecture of the R7FA4M2AC3CFP?

The R7FA4M2AC3CFP features an Arm Cortex-M33 core operating at a maximum frequency of 100 MHz, based on the Armv8-M architecture with TrustZone security extension. It implements PMSAv8 memory protection, dual Systick timers (secure and non-secure), and CoreSight ETM-M33 for debug visibility. This architecture enables deterministic real-time performance with hardware-enforced security partitioning - a key capability of the R7FA4M2AC3CFP in industrial control environments.

Does the R7FA4M2AC3CFP support USB device and host functionality?

Yes, the R7FA4M2AC3CFP integrates a USB 2.0 Full-Speed module (USBFS) that supports both device and host modes. In device mode, it complies with USB Specification 2.0 for full-speed and low-speed transfers; in host mode, it supports full-speed and low-speed peripherals. The module includes an internal transceiver, 10-pipe endpoint buffer, and supports all standard transfer types (control, interrupt, bulk, isochronous). This dual-role capability is native to the R7FA4M2AC3CFP and requires no external PHY.

What security features are implemented in the R7FA4M2AC3CFP?

The R7FA4M2AC3CFP integrates Arm TrustZone for Armv8-M and the Secure Crypto Engine 9 (SCE9), providing hardware-accelerated AES, RSA, ECC, DSA, SHA224, SHA256, and GHASH operations. It supports secure boot, key injection, tamper detection via dedicated pins, and lifecycle management. Memory regions (flash, SRAM, data flash) are partitionable into secure/non-secure zones, and peripherals can be individually attributed. These features are fully implemented in the R7FA4M2AC3CFP and documented in Renesas' R01DS0367EJ0150 datasheet.

How many analog-to-digital and digital-to-analog converter channels does the R7FA4M2AC3CFP include?

The R7FA4M2AC3CFP includes a 12-bit successive approximation ADC (ADC12) with up to 22 input channels, supporting internal temperature sensor and reference voltage inputs. It also integrates two independent 12-bit DACs (DAC12 × 2) for analog output generation. Both converters operate with dedicated analog power domains (AVCC0/AVSS0) and configurable references (VREFH0/VREFL0 for ADC; VREFH/VREFL for DAC). These specifications are confirmed for the R7FA4M2AC3CFP in the RA4M2 datasheet revision 1.50.

What package type and pin count does the R7FA4M2AC3CFP use?

The R7FA4M2AC3CFP uses a 100-pin LQFP package (PLQP0100KB-B), measuring 14 mm × 14 mm with 0.5 mm pitch and Sn (Tin) lead finish. It provides 77 general-purpose I/O pins, 14 of which are 5-V tolerant, along with dedicated power, clock, debug, and peripheral interface pins. This package is explicitly assigned to the R7FA4M2AC3CFP in Renesas' part numbering scheme and functional comparison tables.
