For engineers reviewing the R5F56307DDLA#U0 datasheet, R5F56307DDLA#U0 pinout, R5F56307DDLA#U0 application, or R5F56307DDLA#U0 equivalent, key selection criteria include its 100 MHz operation with 165 DMIPS, 5-V-tolerant I/O (54 pins), -40 to +85°C temperature range, TFLGA-100 package, and integrated IEC 60730-compliant self-test features including CRC, IWDT, and A/D diagnostic capability.

Technical Context

The R5F56307DDLA#U0 implements the RXv1 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code. Its memory subsystem includes zero-wait-state 100-MHz flash and SRAM, plus background-programmable 32-KB data flash supporting 100,000 erase cycles.

Peripherals are clocked independently: ICLK up to 100 MHz for CPU, PCLK up to 50 MHz for peripherals, FCLK up to 50 MHz for FlashIF, and BCLK up to 50 MHz for external bus. It supports four low-power modes-sleep, all-module clock stop, software standby, and deep software standby-with RTC operable from dedicated 2.3–3.6 V backup supply.

FAQ

What is the maximum operating frequency and DMIPS performance of the R5F56307DDLA#U0?

The R5F56307DDLA#U0 operates at a maximum frequency of 100 MHz and delivers 165 DMIPS of processing performance. This is achieved through its optimized RXv1 CPU core with 5-stage pipeline and single-cycle 32-bit multiply instruction. The R5F56307DDLA#U0 maintains this performance across its full operating temperature range (-40 to +85°C) with no derating required.

Does the R5F56307DDLA#U0 support functional safety standards such as IEC 60730?

Yes, the R5F56307DDLA#U0 includes multiple hardware features for IEC 60730 Class B compliance, including oscillation-stop detection, built-in CRC calculator, independent watchdog timer (IWDT), and self-diagnostic function for the 10-bit A/D converter. These capabilities are documented in the R01DS0060EJ0160 datasheet and enable certified safety firmware implementation without external components.

What package type and dimensions does the R5F56307DDLA#U0 use?

The R5F56307DDLA#U0 uses the PTLG0100KA-A package: a 100-pin Thin Fine-Pitch Land Grid Array measuring 5.5 mm × 5.5 mm with 0.5 mm pitch and 0.75 mm height. It is lead-free and RoHS compliant. This compact TFLGA package supports high-density PCB layouts and efficient thermal conduction through the exposed die paddle.

How many analog-to-digital converter channels does the R5F56307DDLA#U0 provide, and what are their specifications?

The R5F56307DDLA#U0 integrates a 12-bit SAR A/D converter with 21 input channels (AN000–AN020), of which AN000–AN010 are available in the 100-pin package per Table 1.2. It also includes an 8-channel 10-bit A/D converter (AN0–AN7). Both converters achieve 1.0 µs conversion time at 50 MHz PCLK and support software, timer, or external trigger initiation.

Is the R5F56307DDLA#U0 pin-compatible with other members of the RX630 Group?

The R5F56307DDLA#U0 shares the same PTLG0100KA-A package and pinout with other RX630 Group devices in the 100-pin TFLGA variant (e.g., R5F56308DDLA#U0, R5F5630ACDLA#U0), enabling direct substitution within the same package family. However, peripheral channel count (e.g., CAN, SCI) varies by flash size and must be verified against Table 1.2 in the datasheet before replacement.
