For engineers reviewing the R5F5630BCDFB#V0 datasheet, R5F5630BCDFB#V0 pinout, R5F5630BCDFB#V0 application, or R5F5630BCDFB#V0 equivalent, key selection criteria include its 144-pin LQFP package, -40 to +85°C operating range, 100 MHz core clock with 165 DMIPS performance, dual A/D resolution support (12-/10-bit), and IEC60730-compliant self-test features including CRC, IWDT, and A/D diagnostic capability.

Technical Context

The R5F5630BCDFB#V0 implements the RXv1 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates a memory protection unit (MPU) and supports little- or big-endian data arrangement per external bus area.

Its clock system includes PLL, 50-MHz HOCO, 125-kHz LOCO, and 32-kHz sub-clock oscillator - all independently configurable for ICLK (up to 100 MHz), PCLK (up to 50 MHz), FCLK (up to 50 MHz), and BCLK (up to 50 MHz). The device supports four low-power modes and battery-backed RTC operation down to 2.3 V on VBATT.

FAQ

What is the maximum operating frequency and core performance of the R5F5630BCDFB#V0?

The R5F5630BCDFB#V0 operates at a maximum system clock frequency of 100 MHz and delivers 165 DMIPS of processing performance using the RXv1 32-bit CPU core. Its single-cycle 32×32 multiplier and hardware floating-point unit enable efficient execution of motor control and signal processing algorithms. This performance level is sustained across the full -40 to +85°C temperature range.

Does the R5F5630BCDFB#V0 include a CAN interface?

No, the R5F5630BCDFB#V0 does not include a CAN module. The 'C' in the part number suffix indicates CAN omission, distinguishing it from the 'D' variant (e.g., R5F5630BDDFB#V0) which integrates three ISO11898-1 compliant CAN channels. All other peripherals - USB 2.0, SCI, RIIC, RSPI, A/D, D/A, and timers - remain identical between the two variants.

What package type and pin count does the R5F5630BCDFB#V0 use?

The R5F5630BCDFB#V0 uses the PLQP0144KA-A package: a 144-pin LQFP with 20 × 20 mm body size and 0.5-mm pin pitch. This package supports 117 general-purpose I/O pins (including 53 with 5-V tolerance), and is compatible with standard surface-mount reflow processes. Pin function details are defined in Table 1.4 of the R01DS0060EJ0160 datasheet.

How much on-chip memory does the R5F5630BCDFB#V0 provide?

The R5F5630BCDFB#V0 integrates 1 Mbyte of on-chip flash memory (executed at 100 MHz with zero wait states), 96 Kbytes of SRAM (also zero wait states), and 32 Kbytes of data flash rated for 100,000 erase/write cycles. The flash supports background programming/erasing, enabling firmware updates without halting application execution.

Is the R5F5630BCDFB#V0 suitable for IEC60730 Class B compliance?

Yes, the R5F5630BCDFB#V0 includes dedicated hardware features for IEC60730 Class B compliance: oscillation-stop detection, independent watchdog timer (IWDT) with dedicated clock source, CRC calculator supporting three polynomials, and self-diagnostic functions for the 10-bit A/D converter. These are documented in the R01DS0060EJ0160 datasheet and supported by Renesas' functional safety documentation package.
