For engineers reviewing the R5F56216BDLE#U0 datasheet, R5F56216BDLE#U0 pinout, R5F56216BDLE#U0 application, or R5F56216BDLE#U0 equivalent, key selection criteria include its TFLGA145 package (145-pin, 9 × 9 mm, 0.65 mm pitch), support for RMII/Ethernet PHY interface, USB transceiver integration, and absence of SDRAM controller or EXDMA - confirmed per RX621 Group specification tables.

Technical Context

The R5F56216BDLE#U0 implements the RXv1 CPU core with CISC-Harvard architecture, 5-stage pipeline, and variable-length instructions. It supports memory protection (MPU), background JTAG debug, and high-speed trace - enabling deterministic real-time execution with interrupt response as low as 5 CPU cycles.

Its clock system includes dual oscillators (main 8–14 MHz crystal + sub 32 kHz RTC crystal), internal PLL for 100 MHz ICLK, and independent PCLK/BCLK domains. Power management features four low-power modes, including Deep Software Standby with RTC retention, and operates across –40°C to +85°C with 2.7–3.6 V supply.

FAQ

What is the maximum operating frequency and CPU performance of the R5F56216BDLE#U0?

The R5F56216BDLE#U0 operates at a maximum frequency of 100 MHz and delivers 165 DMIPS using the 32-bit RXv1 CPU core. Its single-precision IEEE-754 floating-point unit accelerates mathematical operations essential for real-time control algorithms. This performance level is confirmed in the Renesas R01DS0052EJ0140 datasheet Section 1.1 and Table 1.1.

Does the R5F56216BDLE#U0 support Ethernet and USB functionality?

Yes, the R5F56216BDLE#U0 integrates a 10/100 Mbps Ethernet MAC with RMII/MII interface support and a USB 2.0 Full-Speed host/function/OTG module with integrated transceiver. It supports one USB port and requires an external PHY for Ethernet. These capabilities are documented in the RX621 Group block diagram (Figure 1.2) and peripheral summary (Table 1.2).

What memory resources are included in the R5F56216BDLE#U0?

The R5F56216BDLE#U0 includes 256 KB of on-chip flash memory (zero wait states at 100 MHz), 64 KB of SRAM, and 32 KB of data flash rated for 30,000 erase cycles. The data flash supports background erase/program operations without CPU stall, as specified in Section 1.1 of the R01DS0052EJ0140 datasheet.

Which package type and pin count does the R5F56216BDLE#U0 use?

The R5F56216BDLE#U0 uses the TFLGA145 package: a 145-terminal fine-pitch land grid array with 9 × 9 mm body size and 0.65 mm ball pitch. Pin assignments and mechanical dimensions are defined in Figure 1.4 and Table 1.4 of the R01DS0052EJ0140 datasheet.

Is the R5F56216BDLE#U0 compatible with the SDRAM controller or EXDMA features?

No, the R5F56216BDLE#U0 - as an RX621 Group device - does not support the SDRAM area controller or EXDMA controller. These features are explicitly marked "" (not supported) for RX621 in Table 1.2 of the R01DS0052EJ0140 datasheet. Only RX62N Group variants (e.g., R5F562N6BDLE#U0) include them.
