FAQ

What is the maximum operating frequency and CPU performance of the R5F52306AGFM#30?

The R5F52306AGFM#30 operates at a maximum system clock frequency of 54 MHz, delivering 88.56 DMIPS. Its RXv2 core features a 5-stage pipeline, variable-length instructions, and hardware FPU-enabling deterministic real-time execution for motor control and sensor processing. The R5F52306AGFM#30 achieves this performance across its full −40 to +105°C operating range with no wait states on SRAM at 54 MHz.

Does the R5F52306AGFM#30 support USB On-The-Go (OTG) functionality?

Yes, the R5F52306AGFM#30 integrates a USB 2.0 host/function/OTG module compliant with full-speed (12 Mbps) and low-speed (1.5 Mbps) operation. It supports isochronous transfers, BC1.2 battery charging detection, and internal USB power regulation-allowing VCC_USB to be unconnected when VCC is 4.0–5.5 V. This capability is fully implemented in the R5F52306AGFM#30 silicon.

What analog peripherals are included in the R5F52306AGFM#30?

The R5F52306AGFM#30 includes a 12-bit S12ADE A/D converter with 24 input channels and 0.83 µs conversion time, a 12-bit R12DAA D/A converter with two output channels (0.4–AVCC0−0.5 V range), an on-chip temperature sensor (TEMPSA), and two comparator units (CMPBa, 4 total channels). All analog blocks are calibrated and supported by IEC60730 self-test functions.

Is the R5F52306AGFM#30 qualified for extended temperature operation?

Yes, the R5F52306AGFM#30 is the G-version part rated for −40 to +105°C operation. This extended temperature grade is explicitly defined in Renesas' official product table (R01DS0261EJ0120, Table 1.4) and validated across all integrated peripherals-including flash, SRAM, A/D, USB, and CAN-making it suitable for under-hood automotive subsystems and industrial environments.

What security features does the R5F52306AGFM#30 provide for firmware protection?

The R5F52306AGFM#30 incorporates TSIP-Lite: a hardware encryption engine supporting AES-128/256 in ECB, CBC, and GCM modes; a true random number generator; and secure key management that prevents unauthorized access. These features enable secure boot, encrypted firmware updates, and protected data storage-all verified in the R5F52306AGFM#30's silicon implementation per Renesas documentation.
