For engineers reviewing the R5F562N8BDLE#U0 datasheet, R5F562N8BDLE#U0 pinout, R5F562N8BDLE#U0 application, or R5F562N8BDLE#U0 equivalent, key selection criteria include its TFLGA145 package (145-pin, 9 × 9 mm, 0.65 mm pitch), support for RMII/Ethernet PHY interface, dual USB transceivers with integrated PHY, and full CAN mailbox arbitration - all operating across –40°C to +85°C with 2.7–3.6 V supply.

Technical Context

The R5F562N8BDLE#U0 implements the RXv1 CPU core with 5-stage CISC-Harvard pipeline, delivering 165 DMIPS at 100 MHz and supporting little-endian instruction/data layout (with big-endian data option). Its memory subsystem includes zero-wait-state 512 KB flash (10 ns read cycle), 96 KB SRAM with back-up retention in Deep Software Standby Mode, and background-programmable 32 KB data flash rated for 30K erase cycles.

Peripherals are clocked via independent domain dividers: ICLK (8–100 MHz) for CPU/bus, PCLK (8–50 MHz) for peripherals, and BCLK (8–50 MHz) for external bus. The MCU supports four low-power modes, including Deep Software Standby with RTC wake-up, and features dual watchdogs - one 8-bit WDT and one 14-bit IWDT driven by dedicated 125 kHz LOCO.

FAQ

What is the maximum operating frequency and CPU performance of the R5F562N8BDLE#U0?

The R5F562N8BDLE#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 executes math-intensive operations in hardware, and the 5-stage pipeline with variable-length instructions enables ultra-compact code density - critical for memory-constrained embedded applications where R5F562N8BDLE#U0 is deployed.

Does the R5F562N8BDLE#U0 support Ethernet connectivity, and what interface options are available?

Yes, the R5F562N8BDLE#U0 integrates a full Ethernet MAC supporting 10/100 Mbps in half- or full-duplex mode. It provides both MII and RMII interface options, with dedicated pins for RMII signals (ET_RX_DV, ET_TX_EN, ET_RX_ER, etc.) enabling direct connection to standard RMII PHYs. The on-chip EDMAC includes 2 KB transmit and receive FIFOs, reducing CPU overhead during packet processing - a key capability confirmed for R5F562N8BDLE#U0 in the official datasheet.

What are the analog capabilities of the R5F562N8BDLE#U0, particularly regarding ADC and DAC?

The R5F562N8BDLE#U0 includes a 12-bit × 8-channel ADC with 1.0 µs conversion time at 50 MHz PCLK, plus two independent 10-bit DAC channels with 0 V to VREFH output range. It supports flexible trigger sources (software, timer, external) and sample-and-hold functionality. These analog resources are fully validated for R5F562N8BDLE#U0 and enable precision sensor interfacing and analog output control - essential in applications like medical devices where R5F562N8BDLE#U0 serves as the primary controller.

Is the R5F562N8BDLE#U0 pin-compatible with other members of the RX62N Group?

No - R5F562N8BDLE#U0 uses the TFLGA145 package (PTLG0145JB-A), which is not pin-compatible with LQFP144, LQFP100, or LFBGA176 variants in the RX62N Group. While functional peripherals are consistent across the group, pin assignments differ significantly by package type. Engineers must use the specific pinout diagram for R5F562N8BDLE#U0 (Figure 1.4, R01DS0052EJ0140) and cannot assume mechanical or electrical compatibility with other RX62N part numbers.

What low-power modes does the R5F562N8BDLE#U0 support, and how do they impact real-time operation?

The R5F562N8BDLE#U0 supports four low-power modes: Sleep, All-Module Clock Stop, Software Standby, and Deep Software Standby with RTC. In Deep Software Standby, the RTC remains active while CPU and most peripherals halt, drawing minimal current and retaining SRAM contents. Wake-up occurs via RTC alarm or external interrupt - a verified feature enabling battery-backed operation in portable R5F562N8BDLE#U0 deployments such as handheld diagnostic tools.
