It targets industrial networking, motor control, and embedded gateway applications requiring real-time determinism, functional safety support (IEC60730), and secure boot.
For engineers reviewing the R5F564MFDDBG#21 datasheet, R5F564MFDDBG#21 pinout, R5F564MFDDBG#21 application, or R5F564MFDDBG#21 equivalent, key selection criteria include its 177-pin TFLGA package, dual Ethernet + USB + CAN coexistence, 120-MHz deterministic timing, on-chip ECC RAM, and hardware AES/SHA encryption - all validated for -40°C to +105°C operation.
Technical Context
The R5F564MFDDBG#21 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code. It executes at 240 DMIPS @ 120 MHz and supports single-precision IEEE-754 floating-point arithmetic with dedicated FPU and two MAC units.
Its clock system integrates PLL, HOCO (16/18/20 MHz), LOCO (240 kHz), and IWDT-dedicated oscillator, allowing independent domain clocks: ICLK up to 120 MHz (CPU), PCLKA up to 120 MHz (Ethernet/USB/AES), PCLKB up to 60 MHz (timers/ADC), and PCLKC/PCLKD up to 60 MHz (S12AD units).

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F565NEDDFP#30 | Same RX65N group, 144-pin LQFP, 2 MB flash, no Ethernet MAC, adds TrustZone-based secure boot | Lacks dual Ethernet but adds ARM TrustZone isolation; better suited for security-first edge nodes without industrial networking | Select when Ethernet is unnecessary and hardware-enforced secure enclave is mandatory |
| R7FA6M2AF3CFP#AA0 | RX72M group, 100-pin LQFP, 1 MB flash, single Ethernet MAC, 200 MHz CPU, no USB battery charging | Higher CPU speed and integrated op-amps, but reduced I/O count and missing second Ethernet channel | Select for cost-sensitive motion control where single Ethernet suffices and analog integration reduces external components |

Does the R5F564MFDDBG#21 support IEEE 1588 Precision Time Protocol?
Yes, the R5F564MFDDBG#21 integrates a dedicated PTP controller (EPTPC) compliant with IEEE 1588-2008, directly linked to both Ethernet MAC channels. It supports hardware timestamping of ingress/egress frames with sub-microsecond resolution, enabling master/slave clock synchronization in time-sensitive networking applications without external timing ICs or software overhead.
How many CAN interfaces does the R5F564MFDDBG#21 provide, and what standards do they meet?
The R5F564MFDDBG#21 includes three independent CAN modules, each compliant with ISO 11898-1 (Classical CAN) and supporting both standard (11-bit) and extended (29-bit) identifier frames. Each channel provides 32 configurable mailboxes with programmable acceptance filtering, enabling robust multi-bus automotive and industrial communication without external CAN controllers.
What is the maximum clock frequency and associated performance metric for the R5F564MFDDBG#21?
The R5F564MFDDBG#21 operates at a maximum system clock frequency of 120 MHz, delivering 240 DMIPS (Dhrystone MIPS) performance. This is achieved via the RXv2 core's 5-stage pipeline, variable-length instruction set, and dual MAC units - confirmed in Renesas datasheet R01DS0173EJ0120 Section 1.1. The core also supports single-cycle 32×32-bit multiply and two-cycle 32/32-bit divide operations.
Is hardware encryption available on the R5F564MFDDBG#21, and which algorithms are supported?
Yes, the R5F564MFDDBG#21 includes a dedicated hardware encryption engine supporting AES (128/192/256-bit keys), DES/TDES (56-bit), and SHA (SHA-1, SHA-224, SHA-256, HMAC variants).
