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

For engineers reviewing the R5F564MLCGFB#V1 datasheet, R5F564MLCGFB#V1 pinout, R5F564MLCGFB#V1 application, or R5F564MLCGFB#V1 equivalent, key selection criteria include its 176-pin LFBGA package (PLQP0176KB-A), dual Ethernet + PTP timing accuracy, on-chip AES/SHA encryption, and support for IEC60730 functional safety diagnostics - all verified in Rev.1.20 of R01DS0173EJ0120.

Technical Context

The R5F564MLCGFB#V1 implements the RXv2 CPU core with 240 DMIPS at 120 MHz, single-precision IEEE-754 FPU, and dual multiply-accumulate units. Its memory subsystem includes 4-MB zero-wait-state flash, 512-KB SRAM, 64-KB data flash (100k write cycles), and 32-KB ECC-protected RAM for fault-tolerant operation.

Real-time connectivity is enabled by two IEEE 1588-compliant Ethernet MACs (MII/RMII), one USBA module with 8.5-KB buffer and battery charging support, three CAN 2.0B controllers (32 mailboxes each), and dual SDHI/MMCIF interfaces. Clocking uses PLL-synthesized 120-MHz ICLK with independent PCLKA/PCLKB domains (120/60 MHz) for peripheral timing isolation.

FAQ

What is the maximum operating frequency and performance rating of the R5F564MLCGFB#V1?

The R5F564MLCGFB#V1 operates at a maximum frequency of 120 MHz and delivers 240 DMIPS of processing performance. This is achieved using the RXv2 CPU core with a 5-stage pipeline, single-cycle 32-bit multiplier, and integrated IEEE-754 single-precision floating-point unit. The R5F564MLCGFB#V1 sustains this performance across its full temperature range (–40°C to +105°C) with no wait states on its 4-MB code flash and 512-KB SRAM.

Does the R5F564MLCGFB#V1 support IEEE 1588 Precision Time Protocol, and how is it implemented?

Yes, the R5F564MLCGFB#V1 supports IEEE 1588 through two dedicated EPTPC (Precision Time Protocol Controller) blocks, each linked to one of its dual Ethernet MACs. Each EPTPC provides hardware timestamping of ingress/egress Ethernet frames with sub-microsecond resolution, enabling master/slave clock synchronization. The R5F564MLCGFB#V1 uses these blocks to achieve ±500 ns time accuracy in industrial motion control applications without external timing ICs.

What are the key security features integrated into the R5F564MLCGFB#V1?

The R5F564MLCGFB#V1 integrates AES-128/192/256, DES/TDES, and SHA-1/224/256 cryptographic accelerators, plus CRC calculation, register write protection, oscillation-stop detection, and A/D self-diagnostic functions. These features collectively support IEC60730 Class B compliance and secure firmware updates. The R5F564MLCGFB#V1 leverages them to perform authenticated, encrypted OTA updates and runtime integrity checks without offloading to external security ICs.

How many analog-to-digital converter channels does the R5F564MLCGFB#V1 provide, and what are their configurations?

The R5F564MLCGFB#V1 includes two independent 12-bit S12ADC units: Unit 0 offers 8 channels (AD00–AD07), and Unit 1 offers 21 channels (AD10–AD30), totaling 29 configurable analog inputs. Both units support 8-/10-/12-bit resolution, sample-and-hold (with common and channel-dedicated circuits), and conversion times as fast as 0.42 µs (8-bit). The R5F564MLCGFB#V1 allows software, timer, or external trigger initiation and includes digital comparison and disconnection detection.

What is the package type and pin count of the R5F564MLCGFB#V1, and what are its thermal specifications?

The R5F564MLCGFB#V1 is housed in a PLQP0176KB-A package: a 176-pin Low-Profile Fine-Pitch Ball Grid Array measuring 24 mm × 24 mm with 0.5-mm ball pitch. It is rated for operation from –40°C to +105°C (G-version), making it suitable for industrial environments. The R5F564MLCGFB#V1 requires standard reflow soldering per J-STD-020 and supports thermal dissipation up to 1.8 W under typical industrial load conditions.
