For engineers reviewing the R5F5630DDDFB#V0 datasheet, R5F5630DDDFB#V0 pinout, R5F5630DDDFB#V0 application, or R5F5630DDDFB#V0 equivalent, key selection criteria include its 144-pin LQFP package, 100-MHz deterministic execution (165 DMIPS), integrated memory protection unit (MPU), IEC60730 safety support features, and dual A/D converters (12-bit ×21 + 10-bit ×8) with sample-and-hold.

Technical Context

The R5F5630DDDFB#V0 implements a CISC Harvard architecture with 5-stage pipeline and variable-length instructions, enabling ultra-compact code density. Its CPU core supports fast interrupt response, memory protection unit (MPU), and two multiply-and-accumulate units - one for register-to-register and one for memory-to-memory operations.

It integrates three independent clock domains: system clock (ICLK) up to 100 MHz, peripheral module clock (PCLK) up to 50 MHz, and FlashIF clock (FCLK) up to 50 MHz. The device includes dedicated oscillators - 125-kHz LOCO for IWDT, 50-MHz HOCO, and 32-kHz sub-clock for RTC - with main crystal oscillator support from 4 to 16 MHz and PLL-based frequency synthesis.

FAQ

What is the maximum operating frequency and CPU performance of the R5F5630DDDFB#V0?

The R5F5630DDDFB#V0 operates at a maximum system clock frequency of 100 MHz and delivers 165 DMIPS of processing performance. Its 32-bit RX CPU core features a 5-stage pipeline, variable-length instructions, and single-cycle 32×32-bit multiplication - enabling deterministic execution for real-time control tasks. This performance level is validated across the full –40 to +85°C temperature range specified for the R5F5630DDDFB#V0.

Does the R5F5630DDDFB#V0 support IEC60730 functional safety compliance?

Yes, the R5F5630DDDFB#V0 includes dedicated hardware features for IEC60730 Class B compliance: oscillation-stop detection, built-in CRC calculator (with three selectable polynomials), self-diagnostic function for the 10-bit A/D converter, independent watchdog timer (IWDT) with dedicated clock source, and frequency measurement capability for clock monitoring. These capabilities reduce external component count and simplify certification efforts for the R5F5630DDDFB#V0 in safety-critical appliances and industrial controls.

What package type and pin count does the R5F5630DDDFB#V0 use?

The R5F5630DDDFB#V0 uses the PLQP0144KA-A package: a 144-pin LQFP with 0.5-mm pitch and 20 × 20 mm body size. It provides 117 general-purpose I/O pins, including 53 with 5-V tolerance, and supports standard PCB assembly processes. This package matches the pinout and footprint of other RX630 Group devices in the same family, such as R5F5630BDDFB#V0 and R5F5630EDDFB#V0, enabling scalable design reuse.

How much on-chip memory does the R5F5630DDDFB#V0 integrate?

The R5F5630DDDFB#V0 integrates 1.5 Mbytes of on-chip flash memory (zero-wait-state at 100 MHz), 128 Kbytes of SRAM (zero-wait-state at 100 MHz), and 32 Kbytes of reprogrammable data flash rated for 100,000 erase/write cycles. The memory architecture supports background programming/erasing (BGO) for data flash, allowing firmware updates without halting application execution - a key capability for field-upgradable systems using the R5F5630DDDFB#V0.

Which communication interfaces are available on the R5F5630DDDFB#V0?

The R5F5630DDDFB#V0 provides USB 2.0 full-speed (12 Mbps), CAN v2.0B (3 channels, 32 mailboxes each), 13 serial communications interface (SCI) channels supporting asynchronous, clock-synchronous, smart-card, SPI, and I²C modes, 4 I²C bus interfaces (one FM+), 3 RSPI channels, and 1 IEBus channel. This comprehensive interface set enables the R5F5630DDDFB#V0 to serve as a central communication hub in multi-protocol industrial systems without external bridge ICs.
