FAQ

What is the maximum operating frequency and CPU performance of the R5F56308CDLA#U0?

The R5F56308CDLA#U0 operates at a maximum frequency of 100 MHz and delivers 165 DMIPS of processing performance using the 32-bit RXv1 CPU core. Its single-precision IEEE-754 floating-point unit accelerates math-intensive tasks such as motor control algorithms without software emulation overhead. This performance level is validated under industrial temperature conditions (-40 to +85°C) with 2.7–3.6 V supply.

Does the R5F56308CDLA#U0 support IEC 60730 Class B compliance?

Yes, the R5F56308CDLA#U0 includes hardware features required for IEC 60730 Class B compliance: oscillation-stop detection, independent watchdog timer (IWDT) with dedicated clock, CRC calculator, and self-diagnostic capability for the 10-bit A/D converter. These are documented in the R01DS0060EJ0160 datasheet and enable reduced software certification effort in safety-critical appliance and industrial control applications.

What package type and pin count does the R5F56308CDLA#U0 use?

The R5F56308CDLA#U0 uses a 100-pin Thin Fine-Pitch Land Grid Array (TFLGA) package, designated PTLG0100KA-A, measuring 5.5 × 5.5 mm with 0.5-mm pitch. It provides 78 general-purpose I/O pins, 44 of which are 5-V tolerant, and supports boundary scan (JTAG) and FINE two-wire debug interfaces per Renesas documentation.

How much on-chip memory does the R5F56308CDLA#U0 include?

The R5F56308CDLA#U0 integrates 512 KB of on-chip flash memory (zero-wait-state at 100 MHz), 64 KB of SRAM (zero-wait-state at 100 MHz), and 32 KB of reprogrammable data flash rated for 100,000 erase/write cycles. The data flash supports background operation (BGO), allowing program/erase while executing code from main flash-critical for robust firmware updates in field-deployed devices.

Which communication interfaces are integrated into the R5F56308CDLA#U0?

The R5F56308CDLA#U0 integrates USB 2.0 full-speed (12 Mbps), CAN (3 channels, ISO 11898-1 compliant, 32 mailboxes per channel), 13 serial communications interfaces (SCI) supporting asynchronous, LIN, SPI, and I²C modes, 4 I²C bus interfaces (RIIC, one FM+), 3 serial peripheral interfaces (RSPI), and 1 IEBus controller. These interfaces are fully hardware-accelerated and independently clocked for concurrent multi-protocol operation.
