R5F562N7ADFP#H0 from Renesas is a 32-bit RX CPU-based microcontroller delivering 165 DMIPS at 100 MHz, featuring single-precision IEEE-754 FPU, 384 KB flash, 64 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 HMIs and networked embedded gateways.

For engineers reviewing the R5F562N7ADFP#H0 datasheet, R5F562N7ADFP#H0 pinout, R5F562N7ADFP#H0 application, or R5F562N7ADFP#H0 equivalent, key selection criteria include its LQFP100 package with 72 GPIOs (5 V tolerant), 100 MHz real-time performance with MPU support, low-power Deep Software Standby mode with RTC retention, and integrated communication stack for deterministic industrial networking.

Technical Context

The R5F562N7ADFP#H0 implements a CISC-Harvard architecture with 5-stage pipeline, variable-length instructions, and background JTAG debug with high-speed trace. Its memory subsystem includes zero-wait-state 384 KB flash (10 ns read cycle), 64 KB SRAM, and 32 KB background-erasable data flash supporting concurrent CPU execution.

System clocking uses an external 8–14 MHz crystal feeding an internal PLL for 100 MHz ICLK, with independent PCLK (≤50 MHz) and BCLK (≤50 MHz) domains. It integrates dual DMA controllers (DMACA + EXDMAC), DTC, and a 14-channel peripheral interrupt system with 16 priority levels and ≤5-cycle response latency.

FAQ

What is the maximum operating frequency and CPU performance of the R5F562N7ADFP#H0?

The R5F562N7ADFP#H0 operates at a maximum frequency of 100 MHz and delivers 165 DMIPS of processing performance using its 32-bit RX CPU core. It includes a single-precision IEEE-754 floating-point unit, 32 × 32 multiply-to-64-bit accumulator, and five-stage pipeline - enabling deterministic real-time execution for industrial control algorithms within the R5F562N7ADFP#H0.

Does the R5F562N7ADFP#H0 include CAN functionality?

No, the R5F562N7ADFP#H0 does not include a CAN module. The 'A' in its part number (R5F562N7A...) explicitly denotes CAN omission per Renesas' naming convention. For CAN-capable variants, consider R5F562N7BDFP#H0 - same LQFP100 package and memory configuration but with integrated ISO 11898-1 CAN controller (32 mailboxes).

What package type and pin count does the R5F562N7ADFP#H0 use?

The R5F562N7ADFP#H0 uses a 100-pin LQFP package (PLQP0100KB-A), measuring 14 × 14 mm with 0.5 mm pitch. It provides 72 general-purpose I/O pins, including 5 V-tolerant inputs, open-drain outputs, and internal pull-up resistors - optimized for compact industrial control boards requiring mixed-signal integration and external memory expansion.

What are the key differences between R5F562N7ADFP#H0 and R5F56217ADFP#H0?

The R5F562N7ADFP#H0 belongs to the RX62N Group and includes Ethernet MAC (10/100 Mbps), EXDMA controller, and SDRAM interface support. In contrast, R5F56217ADFP#H0 is an RX621 Group part lacking Ethernet, EXDMA, and SDRAM - making the R5F562N7ADFP#H0 suitable for networked applications where those features are essential.

How does the R5F562N7ADFP#H0 handle low-power operation in battery-powered systems?

The R5F562N7ADFP#H0 supports four low-power modes, including Deep Software Standby with RTC and SRAM retention at ~1.5 µA. Its 480 µA/MHz Run mode efficiency, programmable peripheral clock gating, and independent watchdog timers allow extended operation in energy-constrained applications - such as remote sensor nodes - while maintaining real-time wake-up capability via RTC alarm or external interrupt within the R5F562N7ADFP#H0.
