FAQ

What is the maximum operating frequency of the R7FA8T1AFECFB#BA0?

The R7FA8T1AFECFB#BA0 operates at a maximum frequency of 480 MHz using the Arm Cortex-M85 core with Helium™ technology. This speed is achieved via PLL1/PLL2 clock synthesis from internal oscillators (HOCO/MOCO) or external crystals (8–48 MHz). The R7FA8T1AFECFB#BA0 datasheet specifies this as the guaranteed maximum under all operating conditions within the -40°C to +125°C junction temperature range.

Does the R7FA8T1AFECFB#BA0 support secure boot and cryptographic acceleration?

Yes, the R7FA8T1AFECFB#BA0 integrates Renesas Secure IP (RSIP-E51A) with hardware-accelerated AES, RSA, ECC, and HASH functions, plus Arm TrustZone for memory and peripheral isolation. It supports secure boot with immutable ROM-based First Stage Bootloader (FSBL), key injection, and tamper detection. These features are confirmed in the R01DS0419EJ0130 datasheet sections 1.11 and Figure 1.1.

What package type and pin count does the R7FA8T1AFECFB#BA0 use?

The R7FA8T1AFECFB#BA0 uses a 144-pin LQFP package (PLQP0144KA-B), measuring 20 mm × 20 mm with 0.5 mm pitch. This matches the "FB" suffix in its part number and is documented in Table 1.12 and Figure 1.2 of the R01DS0419EJ0130 datasheet. It provides 106 general-purpose I/O pins.

Can the R7FA8T1AFECFB#BA0 be used for Ethernet-enabled applications?

Yes, the R7FA8T1AFECFB#BA0 includes a fully compliant IEEE 802.3 Ethernet MAC controller (ETHERC) coupled with an Ethernet DMA Controller (EDMAC). It supports 10/100 Mbps operation and connects directly to external PHYs via RMII/MII interfaces. This capability is explicitly listed in Table 1.8 and Figure 1.1 of the R01DS0419EJ0130 datasheet.

What analog peripherals are integrated into the R7FA8T1AFECFB#BA0?

The R7FA8T1AFECFB#BA0 integrates dual 12-bit successive approximation ADC12 modules (up to 25 total input channels), dual 12-bit DAC12 modules, two high-speed analog comparators (ACMPHS), and an on-die temperature sensor (TSN). These are detailed in Table 1.9 and Figure 1.1 of the R01DS0419EJ0130 datasheet and support simultaneous sampling and sensor fusion in motor control applications.
