For engineers reviewing the R5F56216BDFB#V0 datasheet, R5F56216BDFB#V0 pinout, R5F56216BDFB#V0 application, or R5F56216BDFB#V0 equivalent, key selection criteria include its LQFP144 package with 144 pins, 100 MHz operation, integrated Ethernet and USB PHY support, CAN interface timing compliance, and real-time clock with calendar function for time-stamped control systems.

Technical Context

The R5F56216BDFB#V0 implements the RXv1 CPU core with CISC-Harvard architecture, 5-stage pipeline, and variable-length instructions, enabling ultra-compact code density and deterministic interrupt response in as few as 5 CPU cycles. It integrates a Memory Protection Unit (MPU) and background JTAG debug with high-speed trace for safety-critical firmware development.

Its system clocking supports external 8–14 MHz crystal + internal PLL for 100 MHz ICLK, with independent division for PCLK (up to 50 MHz) and BCLK (up to 50 MHz). The device includes dedicated DMA channels (4 DMAC + 2 EXDMA), Data Transfer Controller (DTC), and SDRAM interface - though the LQFP144 variant excludes SDRAM and EXDMA per datasheet Table 1.2.

FAQ

What is the maximum operating frequency and CPU performance of the R5F56216BDFB#V0?

The R5F56216BDFB#V0 operates at a maximum frequency of 100 MHz and delivers 165 DMIPS using the 32-bit RXv1 CPU core. Its single-cycle 32 × 32 multiply and 5-cycle interrupt response ensure deterministic real-time execution. The R5F56216BDFB#V0 achieves this performance with zero wait states on 256 KB flash and 64 KB SRAM, verified in Renesas R01DS0052EJ0140 datasheet Section 1.1.

Does the R5F56216BDFB#V0 support Ethernet and CAN simultaneously?

Yes, the R5F56216BDFB#V0 integrates both a 10/100 Mbps Ethernet MAC (MII/RMII) and a CAN 2.0B controller (1 channel, 32 mailboxes) that operate concurrently. Its dedicated DMA channels and DTC allow parallel packet processing without CPU intervention. This capability is confirmed in the R5F56216BDFB#V0 datasheet block diagram (Figure 1.2) and Table 1.2 for RX621 Group functionality.

What are the ADC and DAC specifications of the R5F56216BDFB#V0?

The R5F56216BDFB#V0 includes one 12-bit × 8-channel ADC unit with single sample/hold circuit and 1.0 µs conversion time at 50 MHz PCLK, plus two independent 10-bit DAC channels with 0 V to VREFH output range. These are documented in datasheet Sections 1.1 and Figure 1.2, and apply specifically to the R5F56216BDFB#V0 LQFP144 variant per Table 1.3.

Which package and pin count does the R5F56216BDFB#V0 use?

The R5F56216BDFB#V0 uses the PLQP0144KA-A package: a 144-pin LQFP with 20 × 20 mm body and 0.5 mm pitch. Pin assignments are fully detailed in Figure 1.5 of the R01DS0052EJ0140 datasheet, confirming 144 I/O, power, and peripheral signal terminals - consistent across all RX621 Group LQFP144 variants.

Is the R5F56216BDFB#V0 compatible with Renesas' E2 studio and CS+ development tools?

Yes, the R5F56216BDFB#V0 is fully supported by Renesas E2 studio IDE and CS+ integrated development environment, including debug via JTAG/SWJ, flash programming, and peripheral configuration tools. This support is validated in Renesas' RX Family Tool Support document (R01UL0079EJ0100), which lists R5F56216BDFB#V0 under RX621 Group device support.
