Overview

R5F562N8BDFB#V0 from Renesas is a 100 MHz 32-bit RX CPU core microcontroller with single-precision IEEE-754 FPU, 512 KB flash, 96 KB SRAM, and integrated Ethernet MAC (10/100 Mbps), USB 2.0 Full-Speed Host/Function/OTG, CAN 2.0B (1 channel, 32 mailboxes), 12-bit ADC (8 ch), dual 10-bit DAC, and TFT-LCD controller - deployed in industrial HMIs and networked embedded gateways.

For engineers reviewing the R5F562N8BDFB#V0 datasheet, R5F562N8BDFB#V0 pinout, R5F562N8BDFB#V0 application, or R5F562N8BDFB#V0 equivalent, key selection criteria include its LQFP144 package with 144 pins, 100 MHz operation under 2.7–3.6 V, -40°C to +85°C industrial temperature range, and support for RMII/MII Ethernet PHY interfacing, USB device/host stack coexistence, and real-time deterministic interrupt response (as low as 5 cycles).

Technical Context

The R5F562N8BDFB#V0 implements the RXv1 CPU core with CISC-Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. 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 input to internal PLL, generating independent ICLK (up to 100 MHz), PCLK (up to 50 MHz), and BCLK (up to 50 MHz) domains. The MCU includes dual DMA controllers (DMACA + EXDMAC), Data Transfer Controller (DTC), and dedicated Ethernet DMA with 2 KB TX/RX FIFOs - enabling concurrent high-bandwidth peripheral transfers without CPU intervention.

FAQ

What is the maximum operating frequency and CPU performance of the R5F562N8BDFB#V0?

The R5F562N8BDFB#V0 operates at a maximum frequency of 100 MHz and delivers 165 DMIPS using the 32-bit RX CPU core. Its single-precision IEEE-754 floating-point unit enables efficient real-time computation, and interrupt response as low as 5 CPU cycles ensures deterministic timing for industrial control loops. This performance level is fully sustained across the -40°C to +85°C temperature range.

Does the R5F562N8BDFB#V0 support Ethernet connectivity, and what interface options are available?

Yes, the R5F562N8BDFB#V0 integrates a full Ethernet MAC supporting both 10 Mbps and 100 Mbps operation in half- or full-duplex mode. It provides both MII and RMII interface options for connection to external PHY devices, with dedicated 2 KB transmit and receive FIFOs managed by an on-chip Ethernet DMA controller. The R5F562N8BDFB#V0 does not include an integrated PHY.

What analog peripherals are included in the R5F562N8BDFB#V0, and what are their key specifications?

The R5F562N8BDFB#V0 includes a 12-bit A/D converter with 8 input channels (single sample/hold), capable of 1.0 µs conversion time at 50 MHz PCLK, and two independent 10-bit D/A converters with output voltage range 0 V to VREFH. It also features a 32 KB data flash memory rated for 30,000 erase cycles, used for non-volatile storage of calibration data or firmware parameters within the R5F562N8BDFB#V0.

What package type and pin count does the R5F562N8BDFB#V0 use, and is it pin-compatible with other RX62N variants?

The R5F562N8BDFB#V0 uses a 144-pin LQFP package (PLQP0144KA-A) with 20 × 20 mm body and 0.5 mm pitch. It shares the same LQFP144 footprint with other RX62N Group members like R5F562N7BDFB#V0 and R5F562N8ADFB#V0, enabling hardware reuse across flash/RAM variants. However, pin functions differ for CAN, EXDMA, and SDRAM-related signals versus RX621 Group parts.

How does the R5F562N8BDFB#V0 handle low-power operation, and which modes retain RTC functionality?

The R5F562N8BDFB#V0 supports four low-power modes: Sleep, All-Module Clock Stop, Software Standby, and Deep Software Standby. Only Deep Software Standby retains RTC operation and SRAM content with backup power, drawing minimal current while maintaining calendar time and critical variables. This mode is enabled via software control and requires external VBAT or internal capacitor hold-up, as defined in the R5F562N8BDFB#V0 hardware manual.
