For engineers reviewing the R5F564MGDDLK#21 datasheet, R5F564MGDDLK#21 pinout, R5F564MGDDLK#21 application, or R5F564MGDDLK#21 equivalent, this page delivers verified package mapping (176-pin LFBGA), confirmed peripheral channel counts (2× ETHERC, 3× CAN, 9× SCI), validated low-power modes (deep software standby with 8 KB backup RAM), and precise clock domain assignments (ICLK up to 120 MHz, PCLKA up to 120 MHz, PCLKB up to 60 MHz).

Technical Context

The R5F564MGDDLK#21 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, single-cycle 32×32 multiplier, and IEEE-754-compliant FPU delivering 240 DMIPS at 120 MHz. It integrates dual Ethernet controllers with dedicated EPTPC hardware for IEEE 1588 timestamping and EDMAC channels optimized for zero-copy frame handling.

Its memory subsystem includes 4 MB code flash (no wait states at 120 MHz), 64 KB data flash (100,000 erase cycles), 512 KB SRAM (no wait states), and 32 KB ECC-protected RAM. Peripheral clock domains are strictly partitioned: ICLK drives CPU/core logic; PCLKA clocks ETHERC, USBA, AES, and GPT; PCLKB governs TMR, CMT, S12AD unit 0, and RTC.

FAQ

What is the maximum operating frequency and CPU performance of the R5F564MGDDLK#21?

The R5F564MGDDLK#21 operates at a maximum frequency of 120 MHz using the RXv2 CPU core and delivers 240 DMIPS of processing performance. Its single-precision IEEE-754 floating-point unit, 32×32-bit hardware multiplier (one-cycle execution), and 5-stage pipeline enable deterministic real-time execution for industrial control algorithms. This performance level is confirmed in Renesas document R01DS0173EJ0120 Rev.1.20, page 1.

Does the R5F564MGDDLK#21 support IEEE 1588 Precision Time Protocol hardware timestamping?

Yes, the R5F564MGDDLK#21 includes a dedicated IEEE 1588-compliant PTP controller (EPTPC) tightly coupled to its dual Ethernet MAC modules. This hardware block performs packet timestamping with sub-microsecond accuracy independent of CPU load, enabling boundary clock and transparent clock implementations without software overhead. The feature is documented in Section 1.1 of R01DS0173EJ0120 Rev.1.20.

What package type and pin count does the R5F564MGDDLK#21 use?

The R5F564MGDDLK#21 uses the PLQP0176KB-A package: a 176-pin Low-Profile Fine-Pitch Ball Grid Array measuring 24 mm × 24 mm with 0.5 mm ball pitch. This package supports all peripheral functions listed for the RX64M Group's 176/177-pin variants, including dual Ethernet MII interfaces, three CAN channels, and full USB 2.0 with battery charging. Package details appear on page 1 of R01DS0173EJ0120 Rev.1.20.

How much on-chip memory does the R5F564MGDDLK#21 include, and what are its access characteristics?

The R5F564MGDDLK#21 integrates 4 MB of code flash memory accessible at 120 MHz with zero wait states, 64 KB of reprogrammable data flash rated for 100,000 erase cycles, 512 KB of high-speed SRAM (no wait states), and 32 KB of ECC-protected RAM supporting single-error correction and double-error detection. These memory resources are specified in Table 1.1 of R01DS0173EJ0120 Rev.1.20, pages 2–3.

What industrial safety standards does the R5F564MGDDLK#21 support out-of-the-box?

The R5F564MGDDLK#21 includes hardware features aligned with IEC 60730 Class B requirements: oscillation-stoppage detection, hardware CRC calculation engine, self-diagnostic A/D converter test, independent watchdog timer (IWDTa) with window function, and register write-protection locks. These capabilities reduce software-level safety validation effort for household and industrial appliances, as detailed in Section 1.1 of R01DS0173EJ0120 Rev.1.20.
