For engineers reviewing the R5F564MLHDFC#31 datasheet, R5F564MLHDFC#31 pinout, R5F564MLHDFC#31 application, or R5F564MLHDFC#31 equivalent, this page delivers verified specifications, package mapping to PLQP0176KB-A (176-pin LQFP), functional pin roles, real-world use cases, and two validated alternative MCUs - all grounded in Renesas R01DS0173EJ0120 Rev.1.20 documentation.

Technical Context

The R5F564MLHDFC#31 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code. It supports single-precision IEEE-754 floating-point operations at 240 DMIPS and includes dual multiply-and-accumulate units plus a 32-bit multiplier executing in one cycle.

Its clock system integrates PLL, HOCO (16/18/20 MHz), LOCO (240 kHz), and IWDT-dedicated oscillator, with independent domain clocks: ICLK up to 120 MHz for CPU, PCLKA up to 120 MHz for Ethernet/USB/AES, and PCLKB up to 60 MHz for timers and ADCs - enabling precise peripheral timing isolation.

FAQ

What is the maximum operating frequency and CPU performance of the R5F564MLHDFC#31?

The R5F564MLHDFC#31 operates at a maximum frequency of 120 MHz using the RXv2 32-bit CPU core and delivers 240 DMIPS of processing performance. Its architecture includes a 5-stage pipeline, single-cycle 32-bit multiplier, and IEEE-754-compliant floating-point unit - enabling efficient execution of real-time control algorithms and signal processing tasks without external coprocessors. This performance level is fully sustained across its 4 MB code flash and 512 KB SRAM.

Does the R5F564MLHDFC#31 support IEEE 1588 Precision Time Protocol hardware acceleration?

Yes, the R5F564MLHDFC#31 integrates a dedicated PTP controller (EPTPC) compliant with IEEE 1588-2008, tightly coupled to its dual Ethernet MACs. This hardware block performs timestamp insertion, correction, and synchronization calculations in real time - achieving sub-microsecond clock skew in industrial networks. The R5F564MLHDFC#31 does not rely on software timestamping, ensuring deterministic latency critical for motion control and distributed I/O systems.

What are the key analog capabilities of the R5F564MLHDFC#31 for sensor interfacing?

The R5F564MLHDFC#31 features two independent 12-bit A/D converters (S12ADC): Unit 0 with 8 channels and Unit 1 with 21 channels, both supporting 8/10/12-bit resolution and 0.48 µs conversion time. It also includes two 12-bit D/A channels (R12DA), an on-chip temperature sensor (±1°C accuracy), and analog input disconnection detection. These capabilities enable simultaneous multi-sensor acquisition - such as voltage, current, and thermal monitoring - in applications like energy meters and motor drives.

How does the R5F564MLHDFC#31 support functional safety standards like IEC60730?

The R5F564MLHDFC#31 includes multiple hardware features for IEC60730 Class B compliance: oscillation-stoppage detection, built-in CRC calculator, self-diagnostic A/D converter test, independent watchdog timer (IWDTa) with window function, memory protection unit (MPU), and register write protection. These allow developers to implement safety mechanisms without external components - reducing BOM cost and board area while meeting certification requirements for household appliances and industrial controls.

What package type and pin count does the R5F564MLHDFC#31 use?

The R5F564MLHDFC#31 is housed in the PLQP0176KB-A package: a 176-pin Low-profile Quad Flat Package measuring 24 mm × 24 mm with 0.5 mm pitch and an exposed thermal pad. It provides 127 general-purpose I/O pins, including 19 with 5-V tolerance, open-drain capability, and programmable pull-up resistors - enabling direct interfacing with industrial sensors, actuators, and legacy 5-V logic without level shifters.
