Product details
Overview
R7FA6M2AF3CFB#AA0 from Renesas Electronics is a high-performance 32-bit Arm Cortex-M4 microcontroller with FPU, operating at up to 120 MHz, featuring 1-MB code flash, 384-KB SRAM, dual CAN, Ethernet MAC (ETHERC), USB 2.0 Full-Speed with on-chip transceiver, and hardware security engine (SCE7). It targets industrial control gateways requiring real-time connectivity, secure firmware updates, and deterministic analog I/O.
For engineers reviewing the R7FA6M2AF3CFB#AA0 datasheet, R7FA6M2AF3CFB#AA0 pinout, R7FA6M2AF3CFB#AA0 application, or R7FA6M2AF3CFB#AA0 equivalent, key selection criteria include its -40°C to +105°C temperature rating, 144-pin LQFP package, dual SDHI support for redundant storage, and integrated CTSU for touch HMI in harsh environments.
Technical Context
The R7FA6M2AF3CFB#AA0 implements an Armv7E-M architecture with DSP extensions and single-precision FPU, enabling efficient signal processing in motor control and audio applications. Its memory subsystem includes ECC-protected SRAM (32 KB), parity-checked SRAM (352 KB), and 32-KB data flash rated for 125,000 erase/write cycles - critical for field-updatable firmware storage.
Peripherals are tightly coupled via the Event Link Controller (ELC), allowing autonomous triggering of GPT32EH timers by ADC12 conversion completion or CAN message reception without CPU intervention. The dual-channel Ethernet MAC (ETHERC) interfaces directly with external PHYs and offloads frame handling via the dedicated EDMAC, supporting deterministic real-time communication in industrial Ethernet nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | Arm Cortex-M4 with FPU, 120 MHz max - enables real-time DSP tasks like motor FOC or audio SRC without external co-processor. |
| Memory | 1-MB code flash (40 MHz zero-wait), 32-KB data flash (125k cycles), 384-KB SRAM (32 KB ECC + 352 KB parity) - supports secure OTA updates and robust runtime data logging. |
| Connectivity | Ethernet MAC (ETHERC) + EDMAC, USB 2.0 FS (on-chip transceiver), 2× SDHI, 2× CAN, QSPI, 3× I2C, 2× SPI, 10× SCI - enables multi-protocol edge node with local storage and wired/wireless backhaul readiness. |
| Analog | ADC12 × 2 (13+9 channels, 3 sample-and-hold), DAC12 × 2, ACMPHS × 6, TSN - supports closed-loop analog control with simultaneous sampling and thermal monitoring. |
| Security | SCE7 crypto engine: AES128/192/256, SHA256, RSA/ECC, TRNG, 128-bit UID - provides hardware-accelerated TLS handshake and secure boot verification. |
| Package & Temp | 144-pin LQFP (20 mm × 20 mm, 0.5 mm pitch), -40°C to +105°C - suitable for convection-cooled industrial enclosures without derating. |
| Power | VCC = 2.7–3.6 V, low-power modes including Deep Software Standby with RTC + 8-KB standby SRAM - enables battery-backed timekeeping and wake-on-event in energy-constrained deployments. |
Pinout & Package
Package: 144-pin LQFP (PLQP0144KA-B), 20 mm × 20 mm, 0.5 mm pitch, RoHS-compliant Sn termination.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC / VSS | Digital power supply / ground | 109 I/O pins share common 2.7–3.6 V domain; decoupling required per Renesas layout guidelines to maintain 120 MHz core stability. |
| XTAL / EXTAL | Main clock oscillator interface | Supports 8–24 MHz crystal; used for precise timing of Ethernet MAC, USB, and RTC - critical for IEEE 1588 synchronization readiness. |
| XCIN / XCOUT | Sub-clock oscillator interface | 32.768 kHz crystal input for RTC calendar mode and low-power AGT timer operation during Deep Software Standby. |
| MD | Operating mode select | Fixed at reset to enable single-chip mode; must remain static during operation - prevents unintended boot-mode transitions in fielded systems. |

FAQ
What is the maximum operating frequency and core architecture of the R7FA6M2AF3CFB#AA0?
The R7FA6M2AF3CFB#AA0 features an Arm Cortex-M4 core with floating-point unit (FPU) and operates at a maximum frequency of 120 MHz. It implements the Armv7E-M architecture with DSP instruction set and single-precision IEEE 754-compliant FPU. This enables deterministic execution of control algorithms, digital signal processing, and real-time communication stacks without external coprocessors - a key capability confirmed in the R01DS0357EJ0120 datasheet Section 1.1.
Does the R7FA6M2AF3CFB#AA0 support Ethernet and USB functionality natively?
Yes, the R7FA6M2AF3CFB#AA0 integrates a full Ethernet MAC Controller (ETHERC) compliant with IEEE 802.3 and a USB 2.0 Full-Speed (USBFS) module with on-chip transceiver. ETHERC connects directly to external PHYs via MII, while USBFS supports both host and device roles with 10 configurable pipes. These are not optional add-ons - they are silicon-hardened peripherals validated across all RA6M2 variants, including R7FA6M2AF3CFB#AA0, per datasheet Sections 1.8 and 29–31.
What security features are implemented in hardware on the R7FA6M2AF3CFB#AA0?
The R7FA6M2AF3CFB#AA0 includes the Secure Crypto Engine 7 (SCE7), a dedicated hardware accelerator supporting AES128/192/256, SHA256, RSA/ECC, TRNG, and GHASH. It also provides 128-bit unique ID, memory protection units (MPU), ECC on 32 KB of SRAM, and flash area protection. These features are documented in Section 1.13 and User's Manual Chapter 44, enabling certified secure boot, encrypted firmware updates, and TLS offload without software-only bottlenecks.
What is the operating temperature range and package type for the R7FA6M2AF3CFB#AA0?
The R7FA6M2AF3CFB#AA0 is specified for operation from -40°C to +105°C and is packaged in a 144-pin LQFP (PLQP0144KA-B), measuring 20 mm × 20 mm with 0.5 mm pitch. This package variant is explicitly listed in Table 1.15 of the R01DS0357EJ0120 datasheet and supports industrial-grade thermal reliability without derating - distinct from the 100-pin LQFP or 145-pin LGA variants in the same RA6M2 family.
How does the R7FA6M2AF3CFB#AA0 handle analog signal acquisition and conditioning?
The R7FA6M2AF3CFB#AA0 integrates two independent 12-bit ADC12 units (13+9 channels total), two 12-bit DAC12 outputs, six high-speed analog comparators (ACMPHS), and an on-die temperature sensor (TSN). ADC12 supports selectable resolution (8/10/12-bit), simultaneous sampling via three sample-and-hold circuits, and hardware-triggered conversions linked to timers or ELC events - enabling precise, low-latency analog control loops as detailed in Section 1.9 and Chapter 45 of the datasheet.
