FAQ

What is the maximum operating frequency and performance rating of the R5F56519BDFM#10?

The R5F56519BDFM#10 operates at a maximum frequency of 120 MHz and delivers 240 DMIPS (Dhrystone MIPS) performance. Its RXv2 CPU core supports single-cycle 32×32-bit multiplication and IEEE-754-compliant single-precision floating-point operations - verified in Renesas' R01DS0276EJ0240 datasheet Section 1.1. This performance level enables real-time execution of protocol stacks like TCP/IP and CANopen without external accelerators.

Does the R5F56519BDFM#10 include an integrated Ethernet PHY?

Yes, the R5F56519BDFM#10 integrates both an Ethernet MAC and a full IEEE 802.3-compliant PHY supporting 10/100 Mbps operation in MII or RMII mode. This eliminates the need for an external PHY IC in designs such as industrial gateways or networked HMIs - confirmed in the "Communication function" section of the R01DS0276EJ0240 datasheet (Page 7).

What security features does the R5F56519BDFM#10 provide for firmware protection?

The R5F56519BDFM#10 includes Trusted Secure IP (TSIP) for hardware AES-128/192/256 encryption, Trusted Memory (TM) to prevent code read-out from flash, memory protection unit (MPU) with eight configurable regions, and register write protection. These features collectively support secure boot and firmware update workflows compliant with IEC 62443 - detailed in Sections 1.1 and 2.3 of the official datasheet.

How many A/D converter channels does the R5F56519BDFM#10 support, and what diagnostic capabilities are included?

The R5F56519BDFM#10 integrates two independent 12-bit A/D converter units: S12AD0 with 8 channels and S12AD1 with 21 channels. Both units support self-diagnostic voltage generation (VREFL0/VREFH0 and AVSS1/AVCC1), analog input disconnection detection, and digital window comparison - enabling Class I metrology compliance per IEC 60730, as specified in Section 1.1 (Page 10) of the datasheet.

What is the package type and pin count of the R5F56519BDFM#10, and how many GPIOs are 5-V tolerant?

The R5F56519BDFM#10 uses the PLQP0176KB-A package: a 176-pin LFBGA with 24 mm × 24 mm footprint and 0.5 mm ball pitch. It provides 136 general-purpose I/O pins, of which 19 are 5-V tolerant - enabling direct interfacing with legacy 5-V logic without level shifters, as documented in Table 1.2 (Page 5) of the R01DS0276EJ0240 datasheet.
