It targets industrial automation controllers requiring deterministic real-time I/O, secure firmware updates, and multi-protocol connectivity.

For engineers reviewing the R5F564MGGDLC#21 datasheet, R5F564MGGDLC#21 pinout, R5F564MGGDLC#21 application, or R5F564MGGDLC#21 equivalent, key selection criteria include its 177-pin TFLGA package, -40°C to +105°C operating range (G-version), dual Ethernet with PTP support, on-chip AES/SHA encryption, and 127 general-purpose I/O pins with 5-V tolerance on 19 pins.

Technical Context

The R5F564MGGDLC#21 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code. It integrates dual Ethernet MACs with IEEE 1588 PTP controller (EPTPC) and dedicated EDMAC for hardware-accelerated timestamping and frame processing without CPU intervention.

Its clock system combines external crystal oscillators (8–24 MHz), internal HOCO (16/18/20 MHz), LOCO (240 kHz), and PLL to generate independent clocks: ICLK up to 120 MHz for CPU, PCLKA up to 120 MHz for high-speed peripherals (ETHERC, USBA, AES), and PCLKB up to 60 MHz for timers and analog modules - enabling precise timing isolation across subsystems.

FAQ

What is the maximum operating frequency and core architecture of the R5F564MGGDLC#21?

The R5F564MGGDLC#21 operates at a maximum frequency of 120 MHz using the 32-bit RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions. It delivers 240 DMIPS performance and includes a single-precision IEEE-754 floating-point unit (FPU) for real-time signal processing tasks. The core supports memory protection (MPU), fast interrupt response, and JTAG/FINE debugging interfaces - all confirmed in the official R01DS0173EJ0120 datasheet.

Does the R5F564MGGDLC#21 support IEEE 1588 Precision Time Protocol, and how is it implemented?

Yes, the R5F564MGGDLC#21 supports IEEE 1588-2008 via its integrated PTP Controller for Ethernet (EPTPC), which is hardware-connected to both Ethernet MACs. It provides hardware timestamping of ingress/egress Ethernet frames with sub-microsecond resolution, independent of CPU load. The EPTPC supports master/slave clock roles, transparent clock functionality, and synchronization with external 1588 grandmasters - all detailed in Section 1.1 and Chapter 27 of the R01DS0173EJ0120 datasheet.

What are the flash and RAM capacities of the R5F564MGGDLC#21, and how are they allocated?

The R5F564MGGDLC#21 integrates 4 MB of on-chip code flash memory (no wait states at 120 MHz), 64 KB of reprogrammable data flash (rated for 100,000 erase cycles), 512 KB of general-purpose SRAM (no wait states), 32 KB of ECC-protected RAM (SEC-DED), and 8 KB of standby RAM backed by VBATT. This allocation supports large real-time OS images, secure firmware updates, and reliable data logging - as specified in Table 1.1 of the R01DS0173EJ0120 datasheet.

Which package type and pin count does the R5F564MGGDLC#21 use, and what are its key mechanical features?

The R5F564MGGDLC#21 uses the PTLG0177KA-A package: an 8 mm × 8 mm thin fine-pitch land grid array (TFLGA) with 177 terminals and 0.5-mm pitch. It is lead-free and RoHS compliant, rated for -40°C to +105°C operation (G-version), and features 127 general-purpose I/O pins - 19 of which are 5-V tolerant. This compact, high-density package enables miniaturized industrial designs while maintaining thermal robustness.

What security features are available on the R5F564MGGDLC#21, and are they enabled by default?

The R5F564MGGDLC#21 offers optional hardware-accelerated security including AES-128/192/256, DES/T-DES, SHA-1/224/256, and HMAC cryptographic engines, plus Trusted Memory (TM) protection for flash blocks 8–9. These features are not enabled by default; they require explicit configuration via option bytes and peripheral registers. The TM function prevents unauthorized read-out of protected code regions, supporting secure boot and firmware IP protection - as documented in Sections 1.1 and 32.3 of R01DS0173EJ0120.
