Renesas R5F562N8ADLE#U0

Overview

R5F562N8ADLE#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, and 32 KB data flash. It integrates Ethernet MAC (10/100 Mbps), dual USB 2.0 Full-Speed (Host/Function/OTG), CAN 2.0B (1 channel), 12-bit ADC (8 ch), dual 10-bit DAC, TFT-LCD controller, and RTC - deployed in industrial HMI and networked gateway applications.

For engineers reviewing the R5F562N8ADLE#U0 datasheet, R5F562N8ADLE#U0 pinout, R5F562N8ADLE#U0 application, or R5F562N8ADLE#U0 equivalent, key selection criteria include its TFLGA145 package (145-pin, 0.65 mm pitch), CAN exclusion ('A' suffix), Ethernet+USB+RTC integration, and support for Deep Software Standby with RTC retention.

Technical Context

The R5F562N8ADLE#U0 implements the RXv1 CPU core with 5-stage CISC-Harvard pipeline, delivering 165 DMIPS at 100 MHz and supporting little-endian or big-endian data arrangement. Its memory subsystem includes zero-wait-state 512 KB on-chip flash, 96 KB SRAM with back-up retention in Deep Software Standby, and 32 KB data flash rated for 30K erase cycles with background operation.

Peripherals are clocked via independent dividers: ICLK (8–100 MHz) for CPU/bus masters, PCLK (8–50 MHz) for peripherals, and BCLK (8–50 MHz) for external bus. The device omits CAN (per 'A' in part number) but retains full Ethernet MAC with RMII/MII, dual USB 2.0 PHYs, six SCI, two RIIC, two RSPI, and 126 GPIO (5 V tolerant, open-drain, internal pull-up).

FAQ

What is the maximum operating frequency and CPU performance of the R5F562N8ADLE#U0?

The R5F562N8ADLE#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 algorithms in hardware, eliminating software emulation overhead. This performance level supports real-time motion control, FFT-based signal analysis, and multitasking GUI frameworks - all within the R5F562N8ADLE#U0's integrated architecture.

Does the R5F562N8ADLE#U0 include CAN functionality?

No, the R5F562N8ADLE#U0 does not include CAN. The 'A' in its part number (R5F562N8Axxx) explicitly denotes CAN exclusion per Renesas' naming convention (Table 1.3). It retains Ethernet MAC, dual USB 2.0, six SCI, two RIIC, and two RSPI interfaces. For CAN-required designs, consider the R5F562N8Bxxx variants - but note their different pinout and package compatibility.

What package type and pin count does the R5F562N8ADLE#U0 use?

The R5F562N8ADLE#U0 uses the TFLGA145 package (PTLG0145JB-A): a 9 mm × 9 mm, 0.65 mm pitch, 145-terminal fine-pitch land grid array with exposed thermal pad. This package is validated in Renesas' datasheet R01DS0052EJ0140 Figure 1.4 and supports high-density PCB layouts while maintaining thermal performance for continuous 100 MHz operation - a key distinction from the LQFP144 and LFBGA176 variants in the RX62N family.

How does the R5F562N8ADLE#U0 handle low-power operation in battery-powered applications?

The R5F562N8ADLE#U0 supports four low-power modes, including Deep Software Standby with RTC and SRAM retention - drawing only leakage current while maintaining calendar time and critical data. Its 480 µA/MHz Run Mode efficiency and 125 kHz LOCO for IWDT enable multi-day operation on coin-cell batteries. The R5F562N8ADLE#U0's hardware-accelerated wake-up sources (RTC alarm, external IRQ, USB resume) ensure rapid, deterministic resumption without boot-time delays.

What development tools and debug interfaces are supported by the R5F562N8ADLE#U0?

The R5F562N8ADLE#U0 supports background JTAG debugging with high-speed trace capability, two hardware breakpoint channels, and on-chip ROM correction via address breaks. It is fully compatible with Renesas E2 emulator, CS+ IDE, and e2 studio. Debug access uses standard JTAG pins (TCK, TMS, TDI, TDO, TRST#, and TDO) plus BSCANP - all mapped to the TFLGA145 package per Figure 1.4. No external debug probe voltage translation is needed, as the R5F562N8ADLE#U0 operates natively at 3.3 V logic levels.
