Product details
Overview
R7FA4M2AD3CFL#BA0 from Renesas is a 100 MHz Arm Cortex-M33 microcontroller with 512 KB code flash, 8 KB data flash, and 128 KB SRAM (with parity/ECC), integrated USB 2.0 Full-Speed, SDHI, QSPI, dual 12-bit DACs, 12-bit ADC (22-channel), CAN, and Secure Crypto Engine 9 with TrustZone for secure embedded control in industrial HMI and connected edge devices.
For engineers reviewing the R7FA4M2AD3CFL#BA0 datasheet, R7FA4M2AD3CFL#BA0 pinout, R7FA4M2AD3CFL#BA0 application, or R7FA4M2AD3CFL#BA0 equivalent, key selection considerations include its 48-pin LQFP package, -40°C to +105°C operation, 29 I/O pins with 4× 5-V tolerant inputs, and support for secure boot, capacitive touch (CTSU), and low-power AGT timers.
Technical Context
The R7FA4M2AD3CFL#BA0 implements Armv8-M architecture with TrustZone security, enabling hardware-isolated secure/non-secure worlds. It integrates dual Systick timers, MPU_S/MPU_NS (8 regions each), and CoreSight ETM-M33 for trace-enabled development.
Its system-level integration includes Event Link Controller (ELC) for CPU-free peripheral chaining, Data Transfer Controller (DTC) and 8-channel DMAC for autonomous data movement, and battery-backed RTC with calendar mode - all operating within 2.7–3.6 V supply across extended temperature range.

FAQ
What is the maximum operating frequency of the R7FA4M2AD3CFL#BA0?
The R7FA4M2AD3CFL#BA0 operates at a maximum frequency of 100 MHz using its Arm Cortex-M33 core. This speed is achievable with the internal PLL driven by the main clock oscillator (MOSC) or high-speed on-chip oscillator (HOCO), and is validated across the full -40°C to +105°C temperature range specified for this part.
Does the R7FA4M2AD3CFL#BA0 include an integrated USB transceiver?
Yes, the R7FA4M2AD3CFL#BA0 includes a fully integrated USB 2.0 Full-Speed transceiver with dedicated USB_DP and USB_DM pins. No external PHY is required; only standard 27 Ω series resistors and a 1.5 kΩ pull-up on USB_DP are needed for device-mode enumeration.
How many analog-to-digital converter channels does the R7FA4M2AD3CFL#BA0 support?
The R7FA4M2AD3CFL#BA0 integrates a 12-bit successive approximation ADC (ADC12) with up to 22 selectable analog input channels. These include dedicated pins (AN00–AN13), internal temperature sensor output, and internal reference voltage - all accessible within the 48-pin LQFP package.
What security features are implemented in the R7FA4M2AD3CFL#BA0?
The R7FA4M2AD3CFL#BA0 implements Arm TrustZone for hardware-enforced secure/non-secure world separation, Secure Crypto Engine 9 (SCE9) with AES/RSA/ECC/SHA256 acceleration, tamper detection via dedicated pins, and secure key injection. All features are active and verified in the 48-pin LQFP variant.
Is the R7FA4M2AD3CFL#BA0 pin-compatible with other RA4M2 family members?
No - the R7FA4M2AD3CFL#BA0 uses a 48-pin LQFP package (PLQP0048KB-B) and is not pin-compatible with 64-pin or 100-pin RA4M2 variants. While functionally similar to R7FA4M2AC3CFL#BA0 and R7FA4M2AB3CFL#BA0, pin mapping and I/O count differ across package options.
