For engineers reviewing the R5F56609HGFB#10 datasheet, R5F56609HGFB#10 pinout, R5F56609HGFB#10 application, or R5F56609HGFB#10 equivalent, key selection criteria include its 144-pin LFQFP (PLQP0144KA-B) package, dual 12-bit D/A outputs usable as comparator references, deep software standby mode with RTC retention, and ELC-enabled event-driven peripheral coordination without CPU intervention.

Technical Context

The R5F56609HGFB#10 implements the RXv3 CPU core with single-precision FPU compliant with IEEE 754, 16 register banks for fast context switching, and memory protection unit (MPU) supporting eight configurable protection areas down to 16-byte granularity. Its clock system combines an 8–24 MHz external main oscillator, 32.768 kHz sub-clock, and selectable on-chip oscillators (LOCO/HOCO/IWDT-dedicated), enabling independent domain clocking: ICLK up to 120 MHz, PCLKA up to 120 MHz, PCLKB up to 60 MHz, and ADCLK up to 60 MHz.

Peripheral integration includes MTU3a (9-channel 16/32-bit timer with complementary PWM and dead-time control), DMACAa (8-channel DMA), DTCb (1-channel data transfer controller), and ELC (83 internal event signals) - allowing autonomous inter-module triggering (e.g., MTU overflow initiating A/D conversion) while the CPU remains in sleep mode. Safety features include CAC for clock accuracy monitoring, CRCA with configurable 8-/32-bit polynomials, DOCA for 32-bit arithmetic verification, and register write protection for critical control registers.

FAQ

What is the maximum operating frequency and core architecture of the R5F56609HGFB#10?

The R5F56609HGFB#10 operates at a maximum system clock frequency of 120 MHz using the 32-bit RXv3 CPU core with integrated single-precision floating-point unit (FPU) compliant with IEEE 754. It achieves 709 CoreMark score at this speed and supports collective register bank save for fast interrupt response. The core includes 16 general-purpose 32-bit registers, two 72-bit accumulators, and hardware multiplier/divider units.

Does the R5F56609HGFB#10 support CAN FD, and what standard does it comply with?

Yes, the R5F56609HGFB#10 integrates one CAN FD module compliant with ISO 11898-1:2015, supporting both standard (11-bit) and extended (29-bit) frame formats. It enables data rates up to 5 Mbps in FD mode and includes hardware message filtering, transmit/receive FIFOs, and error confinement - essential for deterministic industrial fieldbus communication in the R5F56609HGFB#10.

What analog peripherals are integrated into the R5F56609HGFB#10?

The R5F56609HGFB#10 integrates a 12-bit S12ADH analog-to-digital converter with 24 input channels and 0.9 µs minimum conversion time, two 12-bit R12DAb digital-to-analog converters (0–AVCC0 output range), four-channel CMPC analog comparators, and an on-die temperature sensor with ±1.0°C relative precision. Both DAC outputs can serve as reference voltages for the comparators, enabling closed-loop analog signal conditioning within the R5F56609HGFB#10.

How does the Event Link Controller (ELC) function in the R5F56609HGFB#10?

The ELC in the R5F56609HGFB#10 allows 83 internal event signals - such as MTU3a overflow, ADC conversion completion, or SCI receive interrupt - to directly trigger actions in other peripherals (e.g., start A/D conversion, toggle a GPIO, or load a timer register) without CPU involvement or interrupt latency. This enables ultra-low-jitter, deterministic peripheral coordination even when the CPU is in deep software standby mode - a core capability of the R5F56609HGFB#10.

What safety and reliability features does the R5F56609HGFB#10 provide for IEC 60730 compliance?

The R5F56609HGFB#10 includes hardware-assisted IEC 60730 compliance features: oscillation-stoppage detection for main/sub clocks, A/D converter self-diagnosis and analog input disconnection detection, clock frequency accuracy measurement circuit (CAC), CRC calculator (CRCA) with configurable polynomials, data operation circuit (DOCA) for 32-bit value verification, and register write protection for critical control registers - all documented in the R5F56609HGFB#10 datasheet as part of its functional safety support.
