FAQ

What is the maximum operating frequency and CPU architecture of the R5F564MLCDLK#21?

The R5F564MLCDLK#21 operates at a maximum frequency of 120 MHz using the 32-bit RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instruction set. It delivers 240 DMIPS performance and includes a single-precision IEEE-754 floating-point unit. This architecture enables deterministic real-time execution and ultra-compact code density essential for resource-constrained industrial applications.

Does the R5F564MLCDLK#21 support IEEE 1588 Precision Time Protocol, and how is it implemented?

Yes, the R5F564MLCDLK#21 supports IEEE 1588-2008 via its integrated EPTPC (Precision Time Protocol Controller) block, which connects directly to both Ethernet MACs. Hardware timestamping occurs at the physical layer with sub-100 ns resolution, and the PTP engine handles message delay measurement, offset correction, and clock synchronization without CPU intervention - enabling precise time coordination in distributed industrial control systems.

What are the memory resources available on the R5F564MLCDLK#21?

The R5F564MLCDLK#21 integrates 4 MB of on-chip code flash memory (no wait states at 120 MHz), 64 KB of reprogrammable data flash (rated for 100,000 erase/write cycles), 512 KB of general-purpose SRAM, 32 KB of ECC-protected RAM (SEC-DED), and 8 KB of battery-backed standby RAM. These resources support complex protocol stacks, secure firmware updates, and real-time data buffering without external memory.

How does the R5F564MLCDLK#21 handle analog-to-digital conversion, and what diagnostic features are included?

The R5F564MLCDLK#21 features two independent 12-bit A/D converters (S12AD0 with 8 channels, S12AD1 with 21 channels), offering 0.48 µs conversion time per channel. Each unit includes self-diagnostic functions that generate internal reference voltages (e.g., VREFL0, VREFH0 × 1/2) for verification, plus analog input disconnection detection and digital comparison modes - fulfilling IEC 60730 Class B requirements for safety-critical industrial sensing.

What package type and thermal specifications apply to the R5F564MLCDLK#21?

The R5F564MLCDLK#21 is packaged in a 177-pin Thin Fine-Pitch Land Grid Array (TFLGA) - model PTLG0177KA-A - measuring 8 mm × 8 mm with 0.5 mm pitch. It is rated for operation from –40°C to +105°C (G-version), making it suitable for harsh industrial environments. The package supports efficient thermal dissipation and is RoHS-compliant with lead-free matte tin finish.
