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

For engineers reviewing the R5F564MGGDBG#21 datasheet, R5F564MGGDBG#21 pinout, R5F564MGGDBG#21 application, or R5F564MGGDBG#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 32 KB ECC-protected RAM for safety-critical data integrity.

Technical Context

The R5F564MGGDBG#21 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code. It integrates dual independent clock domains: ICLK up to 120 MHz for CPU/core logic, and PCLKA/PCLKB up to 120/60 MHz respectively for peripherals - enabling concurrent high-speed Ethernet, USB, and CAN operation without bus contention.

Its peripheral subsystem includes dedicated hardware accelerators: EXDMAC (2-channel) for offloading camera/SDHI transfers, EDMAC (3-channel) for Ethernet DMA, and ELC (Event Link Controller) enabling 119 internal event interlinks - allowing timer-triggered ADC sampling, PWM dead-time insertion, or RTC alarm wake-up without CPU intervention.

FAQ

What is the maximum operating frequency and core architecture of the R5F564MGGDBG#21?

The R5F564MGGDBG#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 performance level enables real-time execution of complex control algorithms and protocol stacks without external co-processors.

Does the R5F564MGGDBG#21 support IEEE 1588 Precision Time Protocol, and how is it implemented?

Yes, the R5F564MGGDBG#21 includes a dedicated PTP controller (EPTPC) compliant with IEEE 1588-2008. It performs hardware timestamping on Ethernet frames at the MAC layer with sub-microsecond resolution, enabling precise time synchronization across distributed industrial networks. The EPTPC integrates directly with the dual ETHERC modules and supports master/slave/clock boundary functions without CPU load.

What are the memory resources available on the R5F564MGGDBG#21?

The R5F564MGGDBG#21 integrates 4 MB of on-chip code flash memory (no wait states at 120 MHz), 512 KB of general-purpose SRAM, 64 KB of reprogrammable data flash (rated for 100,000 erase cycles), 32 KB of ECC-protected RAM, and 8 KB of battery-backed standby RAM. These resources support large real-time OS images, secure firmware updates, and persistent data logging in harsh environments.

How many analog-to-digital converter channels does the R5F564MGGDBG#21 provide, and what are their key capabilities?

The R5F564MGGDBG#21 features two independent 12-bit S12ADC units: Unit 0 with 8 channels and Unit 1 with 21 channels - totaling 29 analog inputs. Each unit supports 8/10/12-bit resolution, conversion times as fast as 0.42 µs, self-diagnostic voltage generation, analog input disconnection detection, and trigger sources including MTU3, GPT, TMR, and external events via ELC.

What package type and thermal characteristics define the R5F564MGGDBG#21?

The R5F564MGGDBG#21 uses the PTLG0177KA-A package: a 177-terminal TFLGA measuring 8 mm × 8 mm with 0.5-mm pitch and an exposed thermal pad. It is rated for operation from –40°C to +105°C (G-version) and draws only 0.3 mA per MHz in active mode, making it suitable for fanless industrial enclosures and thermally constrained designs.
