FAQ

What is the maximum operating frequency and core architecture of the R5F565N7AGLK#20?

The R5F565N7AGLK#20 operates at a maximum frequency of 120 MHz using the 32-bit RXv2 CPU core. It delivers 240 DMIPS performance and includes a single-precision IEEE-754 floating-point unit, 5-stage pipeline, and variable-length instruction set. The core supports memory protection (MPU), fast interrupt response, and JTAG/FINE debugging interfaces - all confirmed in Renesas document R01DS0276EJ0240.

Does the R5F565N7AGLK#20 support Ethernet and CAN simultaneously, and what are the physical layer requirements?

Yes, the R5F565N7AGLK#20 integrates one Ethernet MAC supporting 10/100 Mbps in MII/RMII modes and two ISO 11898-1 CAN controllers (32 mailboxes each). It requires external PHY for Ethernet (e.g., DP83848) and external CAN transceivers (e.g., TJA1042) - both connected directly to dedicated pins. No internal PHY or transceiver is included, as specified in Section 1.1 and Table 1.1 of R01DS0276EJ0240.

What security features does the R5F565N7AGLK#20 include for firmware and data protection?

The R5F565N7AGLK#20 includes AES-128/192/256 encryption engines, Trusted Secure IP (TSIP) for key management and secure boot, memory protection unit (MPU), register write protection, and CRC calculator (CRCA) with configurable polynomials. These features enable secure firmware updates, encrypted storage, and runtime integrity checks - all documented in Sections 1.1 and 1.7 of R01DS0276EJ0240.

What is the package type and pin count of the R5F565N7AGLK#20, and is it RoHS-compliant?

The R5F565N7AGLK#20 uses the PLQP0176KB-A package: a 176-pin LQFP with 24 mm × 24 mm body and 0.5 mm pitch. It is RoHS-compliant and lead-free, as stated in the "Package Information" section of R01DS0276EJ0240 Rev.2.40. This package supports 136 general-purpose I/O pins with 5-V tolerance on 19 pins, open-drain capability, and programmable pull-up resistors.

How does the R5F565N7AGLK#20 handle power management and low-power operation in battery-backed applications?

The R5F565N7AGLK#20 supports four low-power modes (sleep, all-module clock stop, software standby, deep software standby) and draws only 0.19 mA/MHz in active mode. Its RTC remains operational via the VBATT pin during main power loss, and 8 KB of standby RAM retains critical data. Voltage monitoring (LVDA) with three selectable thresholds ensures safe brown-out detection - all detailed in Sections 1.3 and 1.5 of R01DS0276EJ0240.
