Renesas R5F564MLGDLJ#21

Overview

R5F564MLGDLJ#21 from Renesas is a 120-MHz 32-bit RXv2 MCU with single-precision FPU, 4 MB on-chip code flash, 512 KB SRAM (no wait states), IEEE 1588-compliant dual Ethernet MAC, full-speed USB 2.0 with battery charging, and CAN v2.0B - deployed in industrial gateways requiring real-time protocol bridging, secure firmware updates, and deterministic network timing.

For engineers reviewing the R5F564MLGDLJ#21 datasheet, R5F564MLGDLJ#21 pinout, R5F564MLGDLJ#21 application, or R5F564MLGDLJ#21 equivalent, this page delivers verified package mapping (177-pin TFLGA, 8 × 8 mm), confirmed peripheral channel counts (2× ETHERC, 1× USBA, 3× CAN), clock domain assignments (ICLK up to 120 MHz, PCLKA up to 120 MHz, PCLKB up to 60 MHz), and functional distinctions among RX64M variants - all extracted from Renesas Document R01DS0173EJ0120 Rev.1.20.

Technical Context

The R5F564MLGDLJ#21 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dual independent Ethernet controllers (ETHERC) with IEEE 1588 PTP hardware timestamping via EPTPC and dedicated EDMACa channels (2 for ETHERC, 1 for EPTPC), supporting cut-through frame transfer between channels.

Clock management uses a hierarchical scheme: ICLK derived from PLL (up to 120 MHz), PCLKA for high-speed peripherals (ETHERC, USBA, AES), and PCLKB for timers and ADCs (up to 60 MHz). The device supports four low-power modes, RTC battery backup via VBATT, and module-stop control - all coordinated through the Event Link Controller (ELC) for CPU-free peripheral interoperation.

FAQ

What is the maximum operating frequency and CPU architecture of the R5F564MLGDLJ#21?

The R5F564MLGDLJ#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 and includes a single-precision IEEE-754 floating-point unit. This architecture enables deterministic real-time performance for industrial control tasks while maintaining code density advantages over RISC alternatives - a key design goal of the RX64M Group.

Does the R5F564MLGDLJ#21 support IEEE 1588 Precision Time Protocol hardware timestamping?

Yes, the R5F564MLGDLJ#21 integrates a dedicated IEEE 1588-compliant PTP controller (EPTPC) linked to both Ethernet MACs (ETHERC), enabling hardware timestamping of ingress and egress frames with sub-microsecond accuracy. This eliminates software-induced jitter and is essential for time-sensitive networking in industrial automation. The R5F564MLGDLJ#21 datasheet (R01DS0173EJ0120) confirms EPTPC is present and functional in all 177-pin TFLGA variants including R5F564MLGDLJ#21.

What package type and pin count does the R5F564MLGDLJ#21 use?

The R5F564MLGDLJ#21 uses the PTLG0177KA-A package: a 177-pin Thin Fine-Pitch Land Grid Array measuring 8 mm × 8 mm with 0.5 mm pitch. This compact TFLGA variant supports the full peripheral set including dual Ethernet, USBA with battery charging, and 3× CAN - distinguishing it from 176-pin LFBGA and 145-pin TFLGA variants in the RX64M family. Pin compatibility is not guaranteed across package types due to differing signal allocations.

How much on-chip memory does the R5F564MLGDLJ#21 include?

The R5F564MLGDLJ#21 includes 4 MB of on-chip code flash memory (operable at 120 MHz with zero wait states), 64 KB of reprogrammable data flash (rated for 100,000 erase/write cycles), 512 KB of general-purpose SRAM (zero wait state), 32 KB of ECC-protected RAM (SEC-DED), and 8 KB of standby RAM backed by VBATT. These memory resources are fully documented in the R5F564MLGDLJ#21 datasheet section "Outline of Specifications" (Table 1.1).

Is the R5F564MLGDLJ#21 qualified for industrial temperature range operation?

Yes, the R5F564MLGDLJ#21 is rated for operation from –40°C to +105°C (G-version), qualifying it for harsh industrial environments including factory floors, outdoor energy infrastructure, and transportation systems. This extended temperature grade is explicitly specified in the RX64M Group datasheet (R01DS0173EJ0120 Rev.1.20, Page 1) and applies to all devices with the "G" suffix in the part number - confirming R5F564MLGDLJ#21 meets this requirement.
