Renesas R5F562N8ADBG#U0

Overview

R5F562N8ADBG#U0 from Renesas is a 100 MHz 32-bit RX CPU-based microcontroller with single-precision IEEE-754 FPU, 512 KB flash, 96 KB SRAM, 32 KB data flash, Ethernet MAC (10/100 Mbps), USB 2.0 Full-Speed Host/Function/OTG, CAN 2.0B (1 channel), 12-bit ADC (8 ch), dual 10-bit DAC, and TFT-LCD controller - deployed in industrial gateways requiring real-time protocol bridging and secure edge connectivity.

For engineers reviewing the R5F562N8ADBG#U0 datasheet, R5F562N8ADBG#U0 pinout, R5F562N8ADBG#U0 application, or R5F562N8ADBG#U0 equivalent, key selection criteria include its LFBGA176 package, 100 MHz deterministic timing, integrated Ethernet+USB+CAN triple-interface capability, 165 DMIPS performance, and support for deep software standby with RTC retention.

Technical Context

The R5F562N8ADBG#U0 implements the RXv1 CPU core with 5-stage CISC-Harvard pipeline, supporting little-endian instruction/data layout and optional big-endian data mode. It integrates a Memory Protection Unit (MPU) and background JTAG debug with high-speed trace, enabling safe partitioning of firmware tasks in safety-aware applications.

Its clock system uses an external 8–14 MHz crystal feeding an internal PLL to generate ICLK (up to 100 MHz), PCLK (up to 50 MHz), and BCLK (up to 50 MHz). The device supports RMII/MII Ethernet PHY interface, dual USB transceivers with 2 KB buffer RAM, and CAN with 32 configurable mailboxes - all independently clocked and interrupt-sourced.

FAQ

What is the maximum operating frequency and core architecture of the R5F562N8ADBG#U0?

The R5F562N8ADBG#U0 operates at a maximum frequency of 100 MHz and features the 32-bit RXv1 CPU core with 5-stage CISC-Harvard pipeline, delivering 165 DMIPS performance. It supports single-precision IEEE-754 floating-point operations, 32×32→64-bit multiply-accumulate in one instruction, and Memory Protection Unit (MPU) for task isolation - making it suitable for deterministic real-time control applications.

Does the R5F562N8ADBG#U0 include CAN functionality?

No, the R5F562N8ADBG#U0 does not include CAN functionality. Per Renesas part numbering convention, the "A" in the fourth character position (R5F562NADBG) explicitly denotes absence of CAN. This distinguishes it from R5F562N8BDBG, which includes one ISO 11898-1 CAN channel with 32 mailboxes. Designers requiring CAN must select the "B" variant instead.

What package type and pin count does the R5F562N8ADBG#U0 use?

The R5F562N8ADBG#U0 uses the LFBGA176 package (PLBG0176GA-A), a 13 mm × 13 mm body with 0.8 mm ball pitch and 176 I/O balls. This package supports full peripheral access including Ethernet RMII signals, dual USB differential pairs, 12-bit ADC inputs, and TFT-LCD interface lines - verified in Figure 1.3 of the official datasheet R01DS0052EJ0140.

How much on-chip memory does the R5F562N8ADBG#U0 provide?

The R5F562N8ADBG#U0 integrates 512 KB of on-chip flash memory (zero wait-state at 100 MHz), 96 KB of SRAM (with backup retention in Deep Software Standby mode), and 32 KB of data flash rated for 30,000 erase cycles. The data flash supports background erase/program operations, allowing concurrent CPU execution and nonvolatile parameter storage without interruption.

What communication interfaces are supported by the R5F562N8ADBG#U0?

The R5F562N8ADBG#U0 supports USB 2.0 Full-Speed (12 Mbps) Host/Function/OTG with integrated PHY, 10/100 Mbps Ethernet MAC with RMII/MII interface, six SCI channels (asynchronous/clock-sync/smartcard), two I²C interfaces (up to 1 Mbps), two RSPI channels (up to 18 Mbps master), and two USB differential pairs - all accessible in its LFBGA176 package without multiplexing conflicts.
