FAQ

What is the maximum operating frequency and CPU architecture of the R5F564MJHGFB#V1?

The R5F564MJHGFB#V1 operates at a maximum frequency of 120 MHz using the RXv2 32-bit CISC CPU core with 5-stage pipeline and variable-length instructions. It delivers 240 DMIPS performance and includes single-precision IEEE-754 floating-point unit, two MAC units, and hardware divider. This architecture enables efficient real-time control and signal processing in industrial applications where deterministic timing is critical. The R5F564MJHGFB#V1 leverages this core to execute complex protocol stacks and control algorithms without external co-processors.

Does the R5F564MJHGFB#V1 support IEEE 1588 Precision Time Protocol, and how is it implemented?

Yes, the R5F564MJHGFB#V1 includes a dedicated IEEE 1588-compliant PTP controller (EPTPC) tightly coupled to its dual Ethernet MAC (ETHERC). Timestamping is performed in hardware on packet ingress/egress with sub-microsecond resolution, independent of CPU load. The EPTPC synchronizes with MTU3/GPT timers for accurate clock correction and supports one-step and two-step timestamping modes. This enables the R5F564MJHGFB#V1 to serve as a boundary clock or transparent clock in time-sensitive networking applications such as industrial automation and power substations.

What are the memory resources available on the R5F564MJHGFB#V1?

The R5F564MJHGFB#V1 integrates 4 MB of on-chip code flash memory with zero-wait-state access at 120 MHz, 64 KB of reprogrammable data flash (100,000 erase/write cycles), 512 KB of high-speed SRAM, 32 KB of ECC-protected RAM (SEC-DED), and 8 KB of standby RAM backed by VBATT. These resources allow concurrent firmware execution, secure data logging, real-time buffering for Ethernet/USB traffic, and fail-safe state retention during brownout conditions-all within a single R5F564MJHGFB#V1 device.

How does the R5F564MJHGFB#V1 handle analog-to-digital conversion, and what is its resolution?

The R5F564MJHGFB#V1 features two independent 12-bit A/D converters (S12ADC Unit 0 with 8 channels, Unit 1 with 21 channels), supporting configurable resolution of 8-, 10-, or 12-bit per conversion. Conversion time is 0.48 µs per channel at 12-bit resolution. Each unit includes sample-and-hold circuitry, self-diagnostic functions, analog input disconnection detection, and flexible triggering (software, timer, or external event). This makes the R5F564MJHGFB#V1 suitable for high-fidelity sensor acquisition in energy metering and motor control systems.

What package type and temperature grade does the R5F564MJHGFB#V1 use?

The R5F564MJHGFB#V1 uses the PTLG0177KA-A package: a 177-pin Thin Fine-Pitch Land Grid Array measuring 8 mm × 8 mm with 0.5-mm pitch. It is rated for the G-version industrial temperature range of −40°C to +105°C, making it suitable for deployment in harsh environments such as factory floors, outdoor energy infrastructure, and vehicle-mounted diagnostic equipment. This package supports fine-pitch routing and efficient thermal dissipation required for sustained 120-MHz operation.
