Analog Devices Inc./Maxim Integrated DS80C410-FNY+

Overview

DS80C410-FNY+ from Maxim Integrated is a high-performance 8051-based network microcontroller integrating a 10/100 Ethernet MAC, optional CAN 2.0B controller, 1-Wire Master, three hardware serial ports, and 64 I/O pins. It features 64KB on-chip SRAM, a full ROM-resident TCP/IP stack (IPv4/IPv6), and executes instructions in 54ns at 75MHz - enabling real-time industrial Ethernet gateway and sensor node applications.

For engineers reviewing the DS80C410-FNY+ datasheet, DS80C410-FNY+ pinout, DS80C410-FNY+ application, or DS80C410-FNY+ equivalent, key selection considerations include its dual-supply operation (VCC3 = 3.0–3.6V, VCC1 = 1.62–1.98V), 100-pin LQFP package, integrated network stack support for up to 32 TCP connections, and hardware math accelerator for 16/32-bit multiply/divide operations.

Technical Context

The DS80C410-FNY+ implements a flat 24-bit address space supporting up to 16MB contiguous memory with four auto-increment/decrement data pointers to accelerate memory transfers. Its Ethernet MAC supports IEEE 802.3 MII and ENDEC interfaces, configurable for half- or full-duplex operation with multicast/broadcast filtering and VLAN support.

Network boot capability over Ethernet via DHCP/TFTP, preemptive priority-based task scheduling, and Magic Packet® wake-up in ultra-low-power sleep mode are enabled by ROM firmware. The device includes dedicated hardware for 1-Wire timing control and supports CAN 2.0B protocol when enabled - though CAN functionality requires external transceiver and configuration.

Key Specifications

Pinout & Package

FAQ

What is the maximum Ethernet throughput achievable with the DS80C410-FNY+?

The DS80C410-FNY+ Ethernet MAC supports data transfer rates up to 5Mbps through the integrated network stack under typical conditions. This throughput reflects application-layer payload capacity after TCP/IP overhead, buffer management, and CPU scheduling - not raw PHY bandwidth. Real-world performance depends on stack configuration, external PHY selection, and host application efficiency. DS80C410-FNY+ does not guarantee line-rate 100Mbps forwarding due to 8051 core limitations and shared memory bus architecture.

Does the DS80C410-FNY+ include an integrated Ethernet PHY?

No, the DS80C410-FNY+ contains only a Media Access Controller (MAC) - not a physical layer transceiver. It requires an external IEEE 802.3-compliant PHY chip connected via MII or ENDEC interface. The DS80C410-FNY+ provides MDC/MDIO signals for PHY register configuration and supports both 10Mbps (ENDEC) and 100Mbps (MII) modes depending on external component selection.

Is CAN functionality enabled by default on the DS80C410-FNY+?

CAN 2.0B controller functionality is present in silicon but must be explicitly enabled via configuration registers and supported by external CAN transceiver hardware. The DS80C410-FNY+ datasheet confirms optional CAN support - meaning the peripheral is integrated but inactive until initialized in firmware and coupled with appropriate level-shifting transceiver (e.g., MAX3051). No CAN pins are bonded out separately; they share multiplexed port resources.

What power supply configurations does the DS80C410-FNY+ require?

The DS80C410-FNY+ requires two independent supplies: VCC3 (3.0–3.6V) for I/O and core logic, and VCC1 (1.62–1.98V) for internal digital circuitry. Power-fail warning thresholds are specified at VPFW3 = 2.85–3.15V and VPFW1 = 1.52–1.68V, with corresponding reset thresholds. Both rails must be stable during reset assertion and maintained within tolerance during active operation to ensure reliable DS80C410-FNY+ behavior.

Can the DS80C410-FNY+ boot directly from Ethernet without external flash memory?

Yes, the DS80C410-FNY+ supports network boot over Ethernet using DHCP and TFTP protocols - loading application firmware directly from a configured server. This capability relies on ROM-resident boot loader and requires proper network infrastructure (DHCP server, TFTP server, and reachable IP configuration). The DS80C410-FNY+ does not require external nonvolatile memory for initial boot, though local SRAM or optional external flash may be used for runtime storage or fail-safe fallback.
