Product details
Overview
R7FA6M4AF2CBM from Renesas is a high-performance 32-bit Arm Cortex-M33 microcontroller operating at up to 200 MHz, featuring 1 MB dual-bank code flash with background/swap operation, 8 KB data flash, and 256 KB SRAM with parity/ECC. It integrates Ethernet MAC, USB 2.0 Full-Speed, SDHI, QSPI/OSPI, dual CAN, advanced analog (dual 12-bit ADC/DAC, temperature sensor), and hardware security (SCE9 + Arm TrustZone). It targets industrial IoT gateways requiring secure, real-time connectivity and deterministic control.
For engineers reviewing the R7FA6M4AF2CBM datasheet, R7FA6M4AF2CBM pinout, R7FA6M4AF2CBM application, or R7FA6M4AF2CBM equivalent, key selection criteria include its -40°C to +85°C operating range, 144-pin FBGA (7 mm × 7 mm, 0.50 mm pitch) package, dual CAN support for automotive diagnostics, Ethernet MAC with RMII interface, and TrustZone-enabled secure boot and key management - all critical for certified edge node designs.
Technical Context
The R7FA6M4AF2CBM implements Armv8-M architecture with TrustZone, enabling strict isolation between secure and non-secure firmware execution environments. Its memory subsystem includes dual-bank flash supporting live firmware updates without interruption and ECC-protected SRAM for safety-critical data integrity.
Connectivity is centered on deterministic real-time interfaces: two CAN 2.0B controllers (32 mailboxes each), IEEE 802.3-compliant Ethernet MAC with integrated DMA, and USBFS operating in host/device mode. Analog subsystems feature interleaved 5 Msps dual 12-bit ADCs with shared input channels and two independent 12-bit DACs for closed-loop control.

FAQ
What is the maximum operating frequency of the R7FA6M4AF2CBM?
The R7FA6M4AF2CBM operates at a maximum frequency of 200 MHz using its Arm Cortex-M33 core. This speed is achievable with the internal PLL driven by the main clock oscillator (8–24 MHz crystal) or high-speed on-chip oscillator (HOCO). The core maintains full performance across its specified -40°C to +85°C operating temperature range without frequency derating.
Does the R7FA6M4AF2CBM support secure firmware updates?
Yes, the R7FA6M4AF2CBM supports secure firmware updates through its dual-bank code flash architecture with SWAP operation and integrated Secure Crypto Engine 9 (SCE9). Firmware images can be authenticated and decrypted in the secure domain before being written to the inactive bank; SWAP then atomically activates the updated image without system reset or service interruption - a requirement for always-on industrial gateways.
What package type and pin count does the R7FA6M4AF2CBM use?
The R7FA6M4AF2CBM uses a 144-pin Fine-Pitch Ball Grid Array (FBGA) package with part code PLBG0144KB-A, measuring 7 mm × 7 mm with 0.50 mm pitch. It includes an exposed thermal pad for enhanced heat dissipation and supports 109 general-purpose I/O pins, 21 of which are 5-V tolerant - confirmed in the official Renesas datasheet R01DS0365EJ0160.
Can the R7FA6M4AF2CBM operate as a USB host or device?
Yes, the R7FA6M4AF2CBM's USB 2.0 Full-Speed module (USBFS) supports both host and device modes per the Universal Serial Bus Specification 2.0. It includes an internal transceiver, 10 configurable pipes, and buffer memory - enabling direct connection to USB peripherals like flash drives (host mode) or PC-based debug tools (device mode) without external PHY components.
How many CAN interfaces does the R7FA6M4AF2CBM integrate?
The R7FA6M4AF2CBM integrates two Controller Area Network (CAN) 2.0B modules, each supporting up to 32 mailboxes configurable for transmission or reception in normal or FIFO mode. Both modules comply with ISO 11898-1 and support standard (11-bit) and extended (29-bit) identifiers - however, external CAN transceivers are required for physical layer interfacing, as confirmed in the R7FA6M4AF2CBM datasheet section 1.8.
