Renesas R5F56609BDFN#10

Overview

R5F56609BDFN#10 from Renesas is a 32-bit RXv3 core microcontroller operating at up to 120 MHz, delivering 709 CoreMark performance. It integrates 1 Mbyte of on-chip code flash memory with zero-wait-state access, 128 Kbytes of SRAM, 32 Kbytes of reprogrammable data flash (100,000 erase/write cycles), and supports CAN FD, 12-bit A/D and D/A converters, RTC, and remote control signal reception. It targets industrial automation controllers requiring deterministic real-time response, functional safety compliance (IEC60730), and mixed-signal integration.

For engineers reviewing the R5F56609BDFN#10 datasheet, R5F56609BDFN#10 pinout, R5F56609BDFN#10 application, or R5F56609BDFN#10 equivalent, key selection considerations include its 144-pin LFQFP (PLQP0144KA-B) package, dual 12-bit DAC outputs usable as comparator references, deep software standby mode with RTC persistence, and ELC-enabled event-driven peripheral coordination without CPU intervention.

Technical Context

The R5F56609BDFN#10 implements the RXv3 CPU core with single-precision FPU compliant with IEEE 754, 16 register banks for fast context switching, and MPU-based memory protection. 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 (for MTU3a/RSPI/SCI10–11), PCLKB up to 60 MHz (for TMR/CMT/CMTW/S12ADH), and ADCLK up to 60 MHz.

Peripheral coordination is managed via the Event Link Controller (ELC), supporting 83 internal event signals for direct inter-module triggering-e.g., MTU3a PWM edge events initiating A/D conversion or REMC pattern matches toggling GPIO pins-while the CPU remains in sleep mode. Safety features include oscillation-stop detection, CAC clock accuracy monitoring, CRCA hardware CRC (8-/32-bit), DOCA arithmetic unit, and register write protection for critical control registers.

FAQ

What is the maximum operating frequency and flash access performance of the R5F56609BDFN#10?

The R5F56609BDFN#10 operates at a maximum system clock frequency of 120 MHz. Its 1 Mbyte on-chip code flash memory supports zero-wait-state access at this speed, enabling deterministic instruction execution without pipeline stalls. This performance is confirmed in the R01DS0393EJ0100 datasheet Section 1.1, Table 1.1, and verified across all operating voltage ranges (2.7–5.5 V).

Does the R5F56609BDFN#10 support CAN FD, and what standard does it comply with?

Yes, the R5F56609BDFN#10 includes a CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames. It operates at data rates up to 5 Mbps in FD mode and is validated for use in automotive and industrial networks requiring higher bandwidth than classical CAN. This is specified in Section 1.1, Table 1.1 and confirmed in the "Communication function" subsection of the datasheet.

What are the analog capabilities of the R5F56609BDFN#10, particularly regarding ADC and DAC?

The R5F56609BDFN#10 integrates a 24-channel 12-bit S12ADH ADC with minimum 0.9 µs conversion time at 60 MHz ADCLK, and two independent 12-bit R12DAb DAC channels with 0–AVCC0 output range. Both DAC outputs can serve as reference voltages for the four-channel CMPC analog comparator. These specifications are detailed in Sections 1.1 and 22 of the R01DS0393EJ0100 datasheet.

Is the R5F56609BDFN#10 suitable for IEC60730 Class B safety-critical applications?

Yes, the R5F56609BDFN#10 includes dedicated hardware features for IEC60730 compliance: oscillation-stop detection, clock frequency accuracy measurement circuit (CAC), CRC calculator (CRCA), data operation circuit (DOCA), RAM test assist (DOC), and register write protection. These are explicitly listed under "Useful functions for IEC60730 compliance" in the datasheet's Features section and validated in Renesas' functional safety documentation.

What debugging interfaces does the R5F56609BDFN#10 support, and are they available in the 144-pin package?

The R5F56609BDFN#10 supports both JTAG and FINE (one-line) debugging interfaces, and both are available in the 144-pin LFQFP (PLQP0144KA-B) package. The JTAG interface enables full boundary-scan and debug access, while FINE provides minimal-pin debugging for space-constrained designs. This is confirmed in Table 1.2 ("Comparison of Functions for Different Packages") and Section 1.1 of the R01DS0393EJ0100 datasheet.
