FAQ

What is the maximum operating frequency and core architecture of the R7FA4E10D2CFM?

The R7FA4E10D2CFM features an Arm Cortex-M33 core operating at a maximum frequency of 100 MHz, based on the Armv8-M architecture with security extension (r0p4-00rel0). This enables high-performance deterministic execution with hardware-enforced TrustZone isolation, making the R7FA4E10D2CFM suitable for real-time industrial control and secure firmware applications where both speed and security are critical.

Does the R7FA4E10D2CFM include an integrated USB transceiver, and what modes does it support?

Yes, the R7FA4E10D2CFM integrates a full-speed USB 2.0 transceiver within its USBFS module, supporting both device and host controller modes. It complies with USB Specification 2.0, handles all transfer types (control, bulk, interrupt, isochronous), and provides up to 10 configurable pipes. No external PHY is required, reducing BOM cost and board area-key for compact USB-connected devices built around the R7FA4E10D2CFM.

How much flash and RAM memory does the R7FA4E10D2CFM provide, and what are their endurance characteristics?

The R7FA4E10D2CFM provides 512 KB of code flash memory and 8 KB of data flash memory, both supporting background operation for seamless firmware updates. The data flash is rated for 100,000 program/erase cycles. It also includes 128 KB of on-chip SRAM with parity protection for error detection. These memory resources make the R7FA4E10D2CFM well-suited for applications requiring robust firmware storage, runtime data logging, and reliable operation in electrically noisy environments.

What analog peripherals are integrated into the R7FA4E10D2CFM, and how many input channels do they support?

The R7FA4E10D2CFM integrates a 12-bit successive approximation ADC12 with up to 9 selectable analog input channels (AN000–AN016), and a 12-bit DAC12 with one output channel (DA0). These peripherals support simultaneous sampling, external trigger inputs (ADTRG0), and operate with dedicated analog power (AVCC0/AVSS0) and reference pins (VREFH0/VREFL0). This analog capability enables the R7FA4E10D2CFM to serve as a self-contained controller for sensor signal acquisition and analog actuator drive without external converters.

What package type and pin count does the R7FA4E10D2CFM use, and what are its thermal specifications?

The R7FA4E10D2CFM uses a 64-pin LQFP package (PLQP0064KB-C), measuring 10 mm × 10 mm with 0.5 mm pitch and an exposed die pad recommended for connection to VSS. It operates across an industrial temperature range of –40°C to +85°C and requires a supply voltage of 2.7–3.6 V (3.0–3.6 V when USB is active). This package balances I/O density, thermal performance, and manufacturability for mainstream industrial PCB assembly-confirming the R7FA4E10D2CFM's suitability for rugged, volume-production environments.
