Overview
Description
RZ/N2L is an Ethernet communication microprocessor (MPU) that enables customers to easily implement industrial Ethernet and TSN in various IoT and industrial applications like drives, gateways, remote IO and more. RZ/N2L has functions such as an advanced 3-port Gigabit Ethernet switch with TSN, EtherCAT® slave controller, and supports major industrial Ethernet protocols such as EtherCAT, PROFINET RT/IRT, EtherNet/IP™, and OPC UA.
RZ/N2L is optimized for network companion chip use-cases. It easily connects to existing systems through its parallel or serial host interface without requirement of major changes. The real-time protocol is managed by its Arm® Cortex®-R52 core with a maximum operating frequency of 400MHz and large on-chip RAM with ECC, unloading the application CPU. Thanks to its rich peripheral functions such as PWM timer, delta-sigma (ΔΣ) interface, ADC, and more the device also realizes applications like remote I/O, sensor-hub systems, inverter and gateway as a single chip.
A rich software support package with peripheral drivers and many application examples enables rapid evaluation and prototyping.

RZ/N2L: What input voltage is acceptable for VCC1833?
The RZ/N2L has five independent power supply domains (VCC1833_0 to VCC1833_4) for the Ethernet interfaces and xSPI interfaces, and you can supply voltages separately for each of the domains. Ethernet interfaces (target power supply domains: VCC1833_0, VCC1833_1, and VCC1833_2)The supply voltage differs ...
