For engineers reviewing the R5F564MLCDLJ#21 datasheet, R5F564MLCDLJ#21 pinout, R5F564MLCDLJ#21 application, or R5F564MLCDLJ#21 equivalent, this page delivers verified specifications, package mapping to PLQP0176KB-A (176-pin LFBGA), functional pin roles, real-world use cases, and two validated alternative MCUs - all grounded in Renesas R01DS0173EJ0120 Rev.1.20 documentation.

Technical Context

The R5F564MLCDLJ#21 implements the RXv2 CPU core with 240 DMIPS performance at 120 MHz, single-precision IEEE-754 floating-point unit, and memory protection unit (MPU) for safety-critical execution. It integrates dual Ethernet MACs with IEEE 1588 PTP support, three CAN modules (ISO 11898-1 compliant), and a dedicated USBA module with 8.5 KB buffer and battery-charging capability - features confirmed only for 176-/177-pin variants per datasheet Table 1.2.

Its clock system combines external crystal oscillation (8–24 MHz), internal PLL, and multiple on-chip oscillators (LOCO/HOCO/IWDT-dedicated), enabling independent peripheral clock domains: ICLK up to 120 MHz, PCLKA up to 120 MHz (for ETHERC/USBA/AES), PCLKB up to 60 MHz (for timers/ADC), and ADCLK up to 60 MHz - ensuring precise timing isolation across high-speed interfaces and analog subsystems.

FAQ

What is the maximum operating frequency and CPU performance of the R5F564MLCDLJ#21?

The R5F564MLCDLJ#21 operates at a maximum frequency of 120 MHz and delivers 240 DMIPS performance using the RXv2 CPU core. Its single-precision IEEE-754 floating-point unit, 32-bit multiplier (1-cycle execution), and 32-bit divider (2-cycle execution) are fully documented in Renesas R01DS0173EJ0120 Rev.1.20 Section 1.1. This performance level enables real-time signal processing and protocol stack execution in demanding industrial applications.

Does the R5F564MLCDLJ#21 support IEEE 1588 Precision Time Protocol?

Yes, the R5F564MLCDLJ#21 supports IEEE 1588 through its integrated PTP controller (EPTPC), which is directly connected to both Ethernet MACs. The hardware timestamping engine captures transmit/receive packet times with nanosecond resolution, and the EPTPC block handles PTP message parsing and clock synchronization - all confirmed for 176-pin variants in R01DS0173EJ0120 Section 1.1 and Table 1.2.

What package type and pin count does the R5F564MLCDLJ#21 use?

The R5F564MLCDLJ#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 pitch. This package is explicitly assigned to the R5F564MLCDLJ#21 in Renesas' official ordering information and supports all high-pin-count peripherals including dual Ethernet, USBA, and SDHI - as detailed in R01DS0173EJ0120 Page 1 and package dimension tables.

Can the R5F564MLCDLJ#21 perform background programming of its flash memory?

Yes, the R5F564MLCDLJ#21 supports background programming and erasing (BGO) for both code flash and data flash memory. This allows firmware updates or parameter writes to occur concurrently with application code execution - a critical feature for uninterrupted operation in industrial controllers. The BGO functionality is specified in R01DS0173EJ0120 Section 1.1 under "On-chip code flash memory" and "On-chip data flash memory".

What are the key safety and security features built into the R5F564MLCDLJ#21?

The R5F564MLCDLJ#21 includes IEC60730-compliant safety features such as oscillation-stoppage detection, CRC calculation unit, independent watchdog timer (IWDTa) with windowing, self-diagnostic ADC, and register write protection. Optional cryptographic accelerators support AES-128/192/256, DES/T-DES, and SHA-1/224/256 - all documented in R01DS0173EJ0120 Sections 1.1 and Features list. These features reduce certification effort for Class B industrial equipment.
