It targets motor control, PLCs, and IEC 60730-compliant appliances.

For engineers reviewing the R5F56604DDFB#10 datasheet, R5F56604DDFB#10 pinout, R5F56604DDFB#10 application, or R5F56604DDFB#10 equivalent, key selection criteria include its 144-pin LFQFP (PLQP0144KA-B) package, JTAG/FINE debug interface, 2.7–5.5 V supply range, –40°C to +85°C temperature grade (D-version), and on-chip FPU supporting IEEE 754 single-precision operations.

Technical Context

The R5F56604DDFB#10 implements the RXv3 CPU core with 113 instructions, including 11 floating-point and 23 DSP extensions, and supports collective register bank save across 16 banks. Its memory protection unit (MPU) enforces eight configurable protection areas down to 16-byte granularity, while Trusted Memory (TM) secures code flash against unauthorized read access.

Timing architecture includes independent PLL, main clock (8–24 MHz crystal), sub-clock (32.768 kHz), and on-chip oscillators (LOCO/HOCO/IWDT-dedicated), with system clock (ICLK) up to 120 MHz and peripheral clocks (PCLKA/PCLKB/PCLKD) independently configurable up to 120/60/60 MHz respectively - enabling precise clock domain isolation for mixed-signal and real-time tasks.

FAQ

What is the maximum operating frequency and core architecture of the R5F56604DDFB#10?

The R5F56604DDFB#10 operates at a maximum frequency of 120 MHz using the 32-bit RXv3 CPU core, achieving 709 CoreMark. It includes single-precision IEEE 754 floating-point support, 113 instructions (with DSP and FPU extensions), and a collective register bank save function across 16 banks - all confirmed in Renesas datasheet R01DS0393EJ0100.

Does the R5F56604DDFB#10 support CAN FD, and what standard does it comply with?

Yes, the R5F56604DDFB#10 integrates one CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames. This capability is explicitly listed in the "Communication function" section of the datasheet and verified in Table 1.1 and Table 1.2 for the 144-pin package variant.

What package type and pin count does the R5F56604DDFB#10 use?

The R5F56604DDFB#10 uses a 144-pin Low-profile Quad Flat Package (LFQFP) designated PLQP0144KA-B, measuring 20 × 20 mm with 0.5 mm pitch. This is confirmed in the "Package" section of the datasheet and Table 1.2, which specifies 130 general-purpose I/O pins for this variant with JTAG and sub-clock oscillator enabled.

What safety and reliability features are built into the R5F56604DDFB#10 for industrial applications?

The R5F56604DDFB#10 includes MPU (8-region memory protection), Trusted Memory (TM) for flash security, CRCA (CRC calculator), CAC (clock accuracy monitor), DOC-assisted RAM testing, and register write protection - all documented in the "Safety" section of R01DS0393EJ0100 and aligned with IEC 60730 Class B requirements.

Is an external crystal required for the real-time clock (RTC) function in the R5F56604DDFB#10?

Yes, the RTC (RTCC) in the R5F56604DDFB#10 requires connection to a 32.768 kHz crystal via SUBCKI/O pins. The datasheet states that RTC cannot be used in products without a sub-clock oscillator, and Table 1.2 confirms sub-clock oscillator availability for the 144-pin package - making external crystal mandatory for RTC operation.
