DS80C410/DS80C411 Network Microcontrollers with Ethernet and CAN
35 of 102
TERMINOLOGY
The term DS80C410 is used in the remainder of the document to refer to the DS80C410 and DS80C411 unless
otherwise specified.
DETAILED DESCRIPTION
The DS80C410 network microcontroller offers the highest integration available in an 8051 device. Peripherals
include a 10/100 Ethernet MAC, three serial ports, an optional CAN 2.0B controller, 1-Wire Master, and 64 I/O pins.
To enable access to the network, a full application-accessible TCP IPv4/6 network stack and OS are provided in
ROM. The network stack supports up to 32 simultaneous TCP connections and can transfer up to 5Mbps through
the Ethernet MAC. Its maximum system-clock frequency of 75MHz results in a minimum instruction cycle time of
54ns. Access to large program or data memory areas is simplified with a 24-bit addressing scheme that supports
up to 16MB of contiguous memory. To accelerate data transfers between the microcontroller and memory, the
DS80C410 provides four data pointers, each of which can be configured to automatically increment or decrement
upon execution of certain data pointer-related instructions. The DS80C410’s hardware math accelerator further
increases the speed of 32-bit and 16-bit multiply and divide operations as well as high-speed shift, normalization,
and accumulate functions.
With extensive networking and I/O capabilities, the DS80C410 is equipped to serve as a central controller in a
multitiered network. The 10/100 Ethernet media access controller (MAC) enables the DS80C410 to access and
communicate over the Internet. While maintaining a presence on the Internet, the microcontroller can actively
control lower tier networks with dedicated on-chip hardware. These hardware resources include a full CAN 2.0B
controller, a 1-Wire net controller, three full-duplex serial ports, and eight 8-bit ports (up to 64 digital I/O pins).
Instant connectivity and networking support are provided through an embedded 64kB ROM. This ROM contains
firmware to perform a network boot over an Ethernet connection using DHCP in conjunction with TFTP. The ROM
firmware realizes a full, application-accessible TCP/IP stack, supporting both IPv4 and IPv6, and implements UDP,
TCP, DHCP, ICMP, and IGMP. In addition, a priority-based, preemptive task scheduler is also included. The
firmware has been structured so that a MAC address can optionally be acquired from an IEEE-registered DS2502-
E48.
The 10/100 Ethernet MAC featured on the DS80C410 complies with both the IEEE 802.3 MII and ENDEC PHY
interface standards. The MII interface supports 10/100Mbps bus operation, while the ENDEC interface supports
10Mbps operation. The MAC has been designed for low-power standard operation and can optionally be placed
into an ultra-low-power sleep mode, to be awakened manually or by detection of a Magic Packet or wake-up frame.
Incorporating a buffer control unit reduces the burden of Ethernet traffic on the CPU. This unit, after initial
configuration through an SFR interface, manages all Tx/Rx packet activity and status reporting through an on-chip
8kB SRAM. To further reduce host (DS80C410) software intervention, the MAC can be set up to generate a
hardware interrupt following each transmit or receive status report. The DS80C410 MAC can be operated in half-
duplex or full-duplex mode with flow control, and provides multicast/broadcast-address filtering modes as well as
VLAN tag-recognition capability.
The DS80C410 features a full-function CAN 2.0B controller. The DS80C411 does not include this peripheral. This
controller provides 15 total message centers, 14 of which can be configured as either transmit or receive buffers
and one that can serve as a receive double buffer. The device supports standard 11-bit or 29-extended message
identifiers, and offers two separate 8-bit media masks and media arbitration fields to support the use of higher-level
CAN protocols such as DeviceNet and SDS. A special auto-baud mode allows the CAN controller to quickly
determine required bus timing when inserted into a new network. A SIESTA sleep mode has been made available
for times when the CAN controller can be placed into a power-saving mode.
The DS80C410 has resources that far exceed those normally provided on a standard 8-bit microcontroller. Many
functions, which might exist as peripheral circuits to a microcontroller, have been integrated into the DS80C410.
Some of the integrated functions of the DS80C410 include 16 interrupt sources (six external), four timer/counters, a
programmable watchdog timer, a programmable IrDA output clock, an oscillator-fail detection circuit, and an
internal 2X/4X clock multiplier. This frequency multiplier allows the microcontroller to operate at full speed with a
reduced crystal frequency, reducing EMI.
Advanced power-management support positions the DS80C410 for portable and power-conscious applications.
The low-voltage microcontroller core runs from a 1.8V supply while the I/O remains 5V tolerant, operating from a
3.3V supply. A power-management mode (PMM) allows software to switch from the standard machine cycle rate of
