GENERAL DESCRIPTION
FEATURES
Cꢀ High-Performance Architecture
Single 8051 Instruction Cycle in 54ns
DC to 75MHz Clock Rate
The DS80C410/DS80C411 network microcontrollers offer
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. The DS80C410 and DS80C411 also
include 64kBytes internal SRAM for user application
storage and network stack.
Flat 16MB Address Space
Four Data Pointers with Auto-Increment/
Decrement and Select-Accelerate Data Movement
16/32-Bit Math Accelerator
Cꢀ Multitiered Networking and I/O
10/100 Ethernet Media Access Controller (MAC)
Optional CAN 2.0B Controller
To enable access to the network, a full application-
accessible TCP IPv4/6 network stack and OS are provided
in the 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 and DS80C411 provide four
data pointers, each of which can be configured to
automatically increment or decrement upon execution of
certain data pointer-related instructions. High-speed shift,
normalization, accumulate functions and 32-bit/16-bit
multiply and divide operations are optimized by the
DS80C410/DS80C411 hardware math accelerator.
