Product details
Overview
R7FA4M2AC3CFM#HA0 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 for touch sensing, and Secure Crypto Engine 9 with AES/RSA/ECC/SHA256 - deployed in industrial HMI, secure IoT gateways, and motor control systems.
For engineers reviewing the R7FA4M2AC3CFM#HA0 datasheet, R7FA4M2AC3CFM#HA0 pinout, R7FA4M2AC3CFM#HA0 application, or R7FA4M2AC3CFM#HA0 equivalent, key selection criteria include its 64-pin LQFP package, -40°C to +105°C operation, TrustZone-enabled secure boot, integrated SCE9 crypto accelerators, and peripheral set optimized for real-time connectivity and analog signal conditioning.
Technical Context
The R7FA4M2AC3CFM#HA0 implements Armv8-M architecture with dual MPU instances (8 regions each for Secure/Non-secure states) and two independent SysTick timers. Its clock system includes MOSC, SOSC, HOCO/MOCO/LOCO oscillators plus PLL/PLL2, enabling precise timing control across low-power and high-performance modes.
Security is enforced via Arm TrustZone partitioning (up to 3 flash/SRAM regions), tamper-detect pins, secure pin multiplexing, and SCE9 hardware acceleration for AES-128/256, RSA-2048, ECC-P256, SHA256, and GHASH - all coordinated with device lifecycle management and debug access level enforcement.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7FA4M2AD3CFM#HA0 | 512 KB code flash (vs. 384 KB), same 64-pin LQFP, identical peripherals and security features. | Preferred where larger firmware image size or future feature expansion is required. | Select when bootloader, OTA stack, and application logic exceed 384 KB footprint; no PCB change needed. |
| R7FA6M2AF3CFM#HA0 | Arm Cortex-M33 @ 120 MHz, 1 MB flash, 256 KB SRAM, added Ethernet MAC and higher-speed USB HS - different pinout (100-pin only). | Targeted at networked industrial controllers requiring wired connectivity and higher throughput. | Choose only if Ethernet or >100 MHz performance is mandatory; not pin-compatible - requires new layout. |
Compared with R7FA4M2AC3CFM#HA0, the R7FA4M2AD3CFM#HA0 offers direct flash scalability within the same package, while the R7FA6M2AF3CFM#HA0 introduces architectural upgrades incompatible with existing 64-pin designs - making the former the optimal drop-in upgrade path for memory-constrained deployments.

FAQ
What is the maximum operating frequency of the R7FA4M2AC3CFM#HA0?
The R7FA4M2AC3CFM#HA0 operates at a maximum frequency of 100 MHz using its Arm Cortex-M33 core. This speed is achievable with the on-chip PLL driven by the main oscillator (MOSC) or high-speed on-chip oscillator (HOCO). The device maintains full peripheral functionality and timing compliance across its entire -40°C to +105°C operating range, as verified in the R01DS0367EJ0150 datasheet Rev.1.50.
Does the R7FA4M2AC3CFM#HA0 support TrustZone and secure boot?
Yes, the R7FA4M2AC3CFM#HA0 includes Arm TrustZone technology with configurable secure/non-secure memory regions for code flash (up to 3), data flash (up to 2), and SRAM (up to 3). Combined with the Secure Crypto Engine 9 and device lifecycle management, it enables certified secure boot, isolated key storage, and runtime integrity checking - all implemented in hardware without external components.
What package type and pin count does the R7FA4M2AC3CFM#HA0 use?
The R7FA4M2AC3CFM#HA0 uses a 64-pin LQFP package (PLQP0064KB-C), measuring 10 mm × 10 mm with 0.5 mm pitch and Sn (tin) lead-free finish. It provides 43 general-purpose I/O pins, 9 of which are 5-V tolerant, along with dedicated pins for USB, CAN, QSPI, SDHI, and analog functions as defined in the official Renesas pin assignment diagram.
Can the R7FA4M2AC3CFM#HA0 interface directly with a CAN transceiver?
Yes, the R7FA4M2AC3CFM#HA0 includes a built-in CAN 2.0B-compliant controller (CRXn/CTXn pins) but requires an external CAN physical layer transceiver such as the TJA1042 or SN65HVD230. The MCU handles protocol processing, mailbox management, and error handling; the transceiver provides bus-level signaling, fault protection, and common-mode rejection - a standard split-architecture design.
What analog peripherals are integrated into the R7FA4M2AC3CFM#HA0?
The R7FA4M2AC3CFM#HA0 integrates a 12-bit successive approximation ADC12 with up to 22 input channels, two independent 12-bit DAC12 modules, and an on-die temperature sensor (TSN) with linear output. These are supported by dedicated analog power rails (AVCC0/AVSS0), reference voltage pins (VREFH0/VREFL0), and calibration registers - enabling precision sensor signal acquisition and analog output generation without external converters.
