FAQ

What RF standards does the R5F565WEMDBF#20 support out of the box?

The R5F565WEMDBF#20 integrates the R9A06G062GNP Sub-GHz transceiver and supports IEEE 802.15.4g (Smart Utility Networks), ETSI EN 300 220 (Europe), FCC Part 15.247 (USA), and ARIB STD-T108 (Japan) without external RF components. Firmware libraries from Renesas provide certified PHY and MAC layer stacks for these standards, enabling rapid compliance validation for R5F565WEMDBF#20-based designs.

Does the R5F565WEMDBF#20 include hardware support for secure boot and firmware updates?

Yes, the R5F565WEMDBF#20 includes a secure boot ROM with SHA-256 signature verification, AES-128 decryption, and immutable root-of-trust. It validates signed firmware images stored in flash before execution and supports authenticated, encrypted OTA updates via its integrated RF transceiver or USB interface-ensuring end-to-end integrity and confidentiality for R5F565WEMDBF#20 deployments in untrusted environments.

What is the maximum operating frequency and memory configuration of the R5F565WEMDBF#20?

The R5F565WEMDBF#20 operates at up to 120 MHz using its on-chip PLL and features 2 MB of on-chip flash memory with background operation (BGO) and 512 KB of SRAM with parity/ECC protection. The SRAM can be partitioned into tightly coupled memory (TCM) for critical code/data, delivering deterministic access latency essential for real-time RF packet processing in R5F565WEMDBF#20 applications.

How many I/O pins does the R5F565WEMDBF#20 provide, and what peripheral flexibility do they offer?

The R5F565WEMDBF#20 provides 128 user-configurable I/O pins in its LQFP-144 package. Each pin is managed by the Multi-Function Pin Controller (MPC), allowing runtime remapping of peripheral functions-including up to four UARTs, six SPIs, four I²Cs, and two CAN FD interfaces-to any GPIO. This eliminates fixed-function pin constraints and simplifies PCB layout iteration for R5F565WEMDBF#20-based platforms.

Is the R5F565WEMDBF#20 qualified for industrial temperature operation and what packaging does it use?

Yes, the R5F565WEMDBF#20 is rated for industrial temperature operation from −40°C to +85°C and uses a thermally enhanced LQFP-144 package (20 mm × 20 mm, 0.5 mm pitch) with an exposed thermal pad. This package meets JEDEC J-STD-020 moisture sensitivity level 3 and supports reflow soldering per IPC/JEDEC J-STD-020D.2, ensuring long-term reliability in R5F565WEMDBF#20 deployments within factory automation and outdoor metering enclosures.
